—Blaine Anderson, Dreams Come True
Blaine Devon Anderson is a major character on Glee. He is an alumnus of McKinley High School and former Dalton Academy student. Blaine makes his debut in Season Two, in the episode Never Been Kissed as the lead singer of the Dalton Academy Warblers, but later transfers to William McKinley High School at the beginning of Season Three. Blaine is openly gay and is now married to Kurt Hummel as of the episode A Wedding. Despite the obstacles after their break-up in The Break-Up, Blaine reconciles with Kurt and goes on to propose to him at the beginning of Season Five. In New Directions, it is revealed he has been accepted into NYADA and, in the same episode, he graduates from McKinley, along with Tina, Artie, Becky, Brittany, and Sam. It is revealed in Season Six premiere that the engagement was called off and he was cut from NYADA after his grades slips because he is depressed, and he started dating Dave Karofsky afterwards. He was working at Dalton Academy as the coach of the Warblers until Dalton Academy burnt to ground with nothing left to save, so he joins New Directions alongside Kurt, Rachel and Will as a new co-director, while the Warblers join New Directions as well. Karofsky broke it off with Blaine when he realised their 'time was up' after Kurt came back to Lima. Blaine and Kurt finally got married in the final season.
Blaine is implied to come from a wealthy family. His older brother, Cooper, was very critical and domineering when they were young, and it is implied that Blaine is not very close to his father because of his sexuality. Before moving to Dalton Academy, Blaine went to a public school where he was constantly bullied because of his sexuality. Just after he came out, he attended a Sadie Hawkins dance with a friend who was the only other openly gay student at his school. While waiting for his friend's dad to pick them up, he and his friend were jumped by three homophobic bullies and were beat mercilessly. Blaine then decided to transfer to Dalton because of their zero-tolerance bullying policy and has soon gained a lot more confidence since.
Blaine first appears at Dalton Academy, where he runs into Kurt, who is trying to spy on the school's glee club. After leading him down a shortcut to the senior commons, it is revealed that Blaine is the lead singer of the Warblers during a performance of Teenage Dream. Kurt and Blaine later have coffee with Wes and David where Blaine accurately guesses that Kurt is having trouble with bullies at McKinley High. He then gives him advice to stay strong and stand up to Karofsky. Blaine is later approached by Kurt again to confront Karofsky, after his first confrontation ended with Karofsky unexpectedly kissing him. However, Karofsky becomes violently defensive, pushing Blaine against a fence, and leaves. Kurt becomes saddened about Karofsky being his first kiss that "counted." In hopes to cheer him up, Blaine takes Kurt out to lunch and Kurt begins to see Blaine as a role model.
Blaine and Kurt have become very close friends as Kurt even breaks plans to hang out with his best friend, Mercedes. After doing this a second time, Kurt invites Mercedes to a dinner with Blaine at Breadstix where Blaine reveals a little about himself, such as his love for Vogue, his stance on politics involving the gay community Baby, It's Cold Outside, and his love for college football. It is then clear that Kurt is too immersed with Blaine to even spend time with his friend.
Blaine tries to help Kurt acclimate to the customs of Dalton Academy and seemingly aloof Warblers. After Kurt unsuccessfully auditions for a solo at Sectionals with Don't Cry for Me Argentina, Blaine advises Kurt to not try to stick out so much. When Kurt's ward, Pavarotti, appears to have fallen ill, he asks for Blaine's help. Blaine then explains that Pavarotti is merely molting, and tells him that he has "got food, water, he seems to like his cage. Just give it a little while. He'll be singing again in no time," which can be taken as a metaphor for Kurt. The Warblers went on to perform Hey, Soul Sister at Sectionals and tied for first place with the New Directions.
While Kurt studies in one of the commons, Blaine pops in and tells him that he is studying too much and convinces Kurt to help him rehearse a duet he is doing for an off-campus performance. After they both finish singing Baby, It's Cold Outside, Blaine asserts that his female partner will definitely not be as good as Kurt, leaving Kurt smiling. When Blaine leaves, Will, visiting from Lima to ask Kurt for advice on getting a gift for Sue, asks Kurt if Blaine is someone special. Kurt lets him know that he and Blaine are just friends, but admits that he is in love with him.
After practicing a sassy number of Bills, Bills, Bills with the Warblers for Regionals, Blaine and Kurt have coffee with Rachel and Mercedes at The Lima Bean. When the girls let them know their problems at McKinley and how the football team is down several players, Blaine reveals that the football team only needs four more members to compete. Later on, he attends the McKinley Championship football game with Kurt where he watches the girls playing football with the guys and is later seen enjoying the performance of Thriller/Heads Will Roll.
Blaine is out with Kurt at The Lima Bean once again, exchanging opinions on Valentine's Day, which he admits is his favorite holiday. He also tells to Kurt that he has a crush on a guy and asks his advice on if it would be too cheesy if he sang his feelings to . At this point, Kurt assumes that it is him Blaine was referring to and happily encourages Blaine. During an emergency Warbler council meeting, Blaine reveals that he is in love with the junior manager of the Gap at the local mall, much to Kurt's shock, and wants to serenade his crush with help from the Warblers. Blaine serenades his crush, Jeremiah, at the mall by singing a rather inappropriate song, When I Get You Alone, with Kurt and the Warblers. After the performance, Blaine anxiously waits for Jeremiah with Kurt outside. When Jeremiah comes out, he rebuffs Blaine's feelings and tells him that he was not only outed by the performance, but fired from his job as well. Jeremiah then mentions that a relationship between the two would not work, since Blaine is a minor and it would be an illegal.
Heartbroken, Blaine becomes more cynical towards Valentine's Day, lamenting over the fact that he made the relationship all up in his head. Frustrated with Blaine's obliviousness, Kurt then reveals to Blaine that he has feelings for him and that he believed that all the flirting between them meant something more. Blaine then admits that he is clueless and cares about Kurt, but wants them to remain friends since he is inexperienced at dating. Kurt accepts this and compares their relationship to the film When Harry Met Sally, in which the two main characters ended up together. Blaine and Kurt are then seen at the end of the episode, performing Silly Love Songs with the Warblers for the crowd at Breadstix, including Kurt's friends.
Blaine attends Rachel's basement party with Kurt where Blaine gets really drunk and ends up making out with Rachel during a game of spin the bottle. Afterwards, Blaine and Rachel sing Don't You Want Me on Rachel's makeshift Oscar stage. Because Blaine was so drunk and unable, Kurt lets him sleep at his house where he is discovered the next morning in Kurt's bed by Kurt's father, Burt. While Blaine is out on another coffee date with Kurt, Rachel calls Blaine and asks him out, to which he accepts. Blaine then begins to question his sexuality, to which Kurt dismisses that bisexuality does not exist. Blaine gets upset at Kurt for not understanding his confusion and accuses Kurt of acting like Karofsky, storming out afterwards. Blaine agrees to date Rachel, but Rachel tells Kurt that while the date was lovely, there was no kiss at the end like she had expected. After Kurt mocks the date for being too gay, Rachel bets that she can kiss Blaine, while sober, to prove that he is at least bisexual. However, when she actually does kiss Blaine, he confirms that he is without a doubt "100% gay." Rachel does not take the news badly, as she believes it would be perfect drama and inspiration for writing an original song.
Sue visits Kurt at the Lima Bean, where he is having coffee with Blaine. In an effort to form an alliance, Sue tells them about how New Directions are set to perform "sexy numbers" and encourages them to outsex them to impress the judges at Regionals. Despite Kurt being dismissive, Blaine immediately decides that the Warblers need to be sexier. He invites the girls from Dalton's sister school, Crawford Country Day, to view a Warbler performance of Animal to test their sex appeal. During the performance, Blaine notices how awkward Kurt's sexy faces are and tells him he needs lessons on how to look sexy. However, Kurt's lack of sexual knowledge causes a rift between them and Blaine believes that extra steps need to be taken. Blaine approaches Burt at his auto shop and boldly asks him to give Kurt "the talk." Sensing that Burt is uncomfortable, Blaine confides to him that his relationship with his father is not the same as Burt's with Kurt. He tells him that he worked on a car with his father because he believed his father wanted him to get his hands dirty to make him straight. He also reveals that his father never had "the talk" with him and he had to search himself. He advises Burt to initiate the sex discussion because he fears that Kurt will be ill-informed due to him shying away from the subject.
Blaine opens the episode, singing lead in Misery, where an unimpressed Kurt tries to ignore him. After the performance, Kurt tells him that sometimes it feels that they are not The Warblers, but "Blaine and The Pips." Blaine then rebuffs this claim by saying the council decides who sings. During a meeting with the Warblers, Kurt informs everyone that Pavarotti has died and sings Blackbird as an ode to their fallen ward. It is then that Blaine realizes that he is in love with Kurt. At the next meeting, Blaine proposes that they try something different and pitches a duet with him and Kurt for Regionals, much to Kurt's surprise. The Warblers follow Blaine's lead and calls for a vote where they unanimously decide that Blaine and Kurt will perform the duet together. Blaine later interrupts Kurt decorating Pavarotti's casket to rehearse their duet. Blaine finally tells Kurt how he feels and admits that he wants to be with Kurt. He tells him that Kurt moves him and leans in for their first kiss. Blaine backs away, bashful, and remarks that they should practice. Kurt impishly replies, "I thought we were," and both boys initiate a more passionate second kiss. At the Regionals competition, Blaine and Kurt perform Candles and Blaine ends the performance with Raise Your Glass. In the end, they do not win at Regionals, mostly due to one of the judges' homophobic views, and New Directions advance to Nationals. Afterwards, Blaine and Kurt bury Pavarotti and Blaine says that despite their loss, they still have each other. They hold hands as they walk away from Pavarotti's grave.
Blaine goes with Kurt to McKinley for the benefit concert New Directions is holding for the The Brainiacs. He comments that Kurt seems to miss McKinley. The pair are then interrupted by Karofsky, who starts insulting their presence at the school. Blaine then bravely stands up to Karofsky and shoves him. Karofsky then shoves Blaine back and before things can escalate, Santana intervenes and threatens Karofsky to leave them alone. Blaine and Kurt are revealed to be the only ones, other than The Heckling Club, attending the concert. Despite this, they enjoy the performances and support Kurt's friends.
Blaine joins Kurt and his friends Mercedes, Santana and Tina at the Lima Bean to discuss the possibility of Kurt transferring back to McKinley. Blaine chimes in saying that if it was not for Karofsky, he would be all for it and that he just wants Kurt to be safe. This helps Santana cook up a scheme to get Kurt back to McKinley and win prom queen. When Santana's plan works and Kurt transfers, Blaine decides to serenade him with Somewhere Only We Know in the McKinley courtyard with the Warblers as a way to say goodbye. As the song ends, Kurt hugs Blaine, tears in both their eyes. During the hug, Kurt tells him that he will never say goodbye to him. Blaine takes one last look at Kurt as he joins his friends, knowing he will be happy with his friends, and leaves.
Blaine and Kurt are having dinner at Breadstix where Kurt asks Blaine out to his junior prom. Blaine is reluctant to go at first and reveals that he once asked a guy out to a Sadie Hawkins dance at his old school and three guys had beaten them up. Kurt tells him that he does not have to go if he does not feel comfortable. Touched, Blaine agrees to go to prom with Kurt. Later, at Kurt's house, Kurt shows Blaine, Finn and Burt the outfit he plans to wear to prom: a kilt. Blaine then agrees with Burt when he tells Kurt that kilt is attracting unwanted attention. Kurt gets defensive and says he will go to prom in his kilt with or without Blaine. At the prom, Blaine and Kurt dance to Puck, Sam and Artie's energetic performance of Friday, but decide to skip the slow dance to Rachel's Jar of Hearts, fearing backlash. Blaine performs next with Brittany and Tina, singing I'm Not Gonna Teach Your Boyfriend How to Dance with You. During his performance, a fight breaks out between Finn and Jesse St. James over Rachel. In a shocking twist, Kurt finds that he has been voted prom queen as a cruel joke with Karofsky being the prom king. Blaine chases Kurt into the hall after he runs away, hurt over the fact that the students decided to humiliate him. While in the hallway, Blaine attempts to comfort him by telling him that it was just a stupid joke. Kurt states that the bullies cannot touch them or what they have and gains the confidence to go out there and get coronated. Kurt accepts his crown and sceptor and prepares to have the King and Queen dance with Karofsky. When Karofsky, afraid of being outed in front of everyone, runs off saying he cannot dance with Kurt, Blaine steps in and asks Kurt to dance during Mercedes and Santana's performance of Dancing Queen. At the end of the episode, Blaine and Kurt are seen taking a photo together with the rest of New Directions.
Blaine and Kurt are having another coffee date with each other, following the New Directions' devastating loss at Nationals in New York. Blaine then tells Kurt that he loves him for the first time. Kurt says that he loves Blaine too and states that he has had a pretty good year.
In Season Three, Darren Criss, who portrays Blaine was promoted to series main cast. He remained in this position for the rest of the series.
Blaine and Kurt are having coffee at The Lima Bean where Kurt urges Blaine to transfer to McKinley. Blaine seems hesitant at first, claiming he has not decided because he will miss his friends at Dalton, to which Kurt replies that he wants his senior year to be magical, but that the only way that will happen is if he gets to spend every minute with Blaine. Sometime within the first week, Blaine arrives at McKinley, not dressed in his Dalton uniform, confirming to Kurt that he has transferred. Blaine assures Kurt that he transferred for him and could not stand to be apart from the person he loves. In order to get the New Directions to warm up to him, Blaine performs It's Not Unusual with Santana and the Cheerios in the courtyard. However, this backfires when Santana and the Cheerios pour lighter fluid on a purple piano in the courtyard as part of Sue's political protest against the arts, and it is set ablaze by Quinn's cigarette. This occurrence leads to some members, notably Finn, to disapprove of Blaine's presence. Despite this, Blaine joins the New Directions in performing You Can't Stop the Beat.
When the school musical is announced as West Side Story, Blaine informs Kurt that he plans to audition for the role of Tony, much to Kurt's chargin as he feels that Blaine would be a shoe-in for the role. When Blaine realizes how upset Kurt is over it, Blaine decides to step aside and let Kurt audition for Tony while he auditions for Bernardo or Officer Krupke, using his status as a junior as an excuse. However, when Blaine auditions with a brilliant rendition of Something's Coming, Artie asks him if he could read for Tony instead.
Before the results of the casting list is revealed, Kurt surprises Blaine with beautiful flowers as a way to express that no matter who won the role of Tony, they will still be happy for each other. The casting list is posted and it is revealed that Blaine did win the role of Tony, opposite Rachel who got the role by default after a bitter Mercedes refused the role and leading her to quit.
In order to cheer up New Directions after Mercedes quit, Blaine performs Last Friday Night in the choir room to remind the group what glee is all about—fun. Though it was well received by the majority of New Directions, Santana is displeased with the fact that Glee Club is turning into the "Blaine and Rachel show," prompting her to quit the club and convince Brittany to join The Troubletones, founded by Rachel's biological mother, Shelby, and spoiled rich girl Sugar.
While rehearsing Tonight for West Side Story, Blaine and Rachel are informed by Artie that their performance lacks sexual passion, which makes everyone, including Emma and Beiste, uncomfortable. After Blaine and Rachel admit that they are virgins, Artie expresses that doubt that they could genuinely play Tony and Maria without first experiencing sex. Kurt later brings the topic of sex up to Blaine in Blaine's bedroom, to which Blaine responds by saying that he wants Kurt to be comfortable. Blaine later pays a visit to Dalton Academy to invite the Warblers to see West Side Story and gets sucked into a performance of Uptown Girl led by Nick, Thad, and a new Warbler named Sebastian Smythe. After some obvious flirting, Blaine and Sebastian later have coffee together at the Lima Bean where they are interrupted by Kurt, who instantly feels threatened by Sebastian's advances on Blaine. Sebastian then proposes that they got to the gay bar Scandals in West Lima. After getting a couple of fake IDs, Blaine and Kurt head down to the bar with Sebastian where Blaine becomes obnoxiously drunk and attempts to have sex with Kurt in the backseat of his car. This leads to an explosive fight that ends with Blaine storming off and walking home.
On opening night of the musical, Blaine and Rachel have a conversation about their failed attempts at losing their virginity. Rachel, inspired by Tina's reminiscence of her first time, informs Blaine that the roles of Tony and Maria are more about finding their soulmates and tapping into that emotion to portray two people in love, which she says is an experience that each of them know very well with their respective partners. Blaine apologizes to Kurt in the auditorium after opening night ends in success and Kurt apologizes for ever agreeing to go to Scandals. Blaine tells Kurt that Sebastian means nothing to him and loves Kurt. The couple then share a kiss. At the end of the episode, during an intercut of Blaine and Rachel duetting One Hand, One Heart, Blaine and Kurt lie on a bed together, sharing Eskimo kisses and soft touches, implying that they are about to have sex for the first time.
Blaine helps Puck sing Hot for Teacher with Mike and Finn, unaware of Puck's attraction to Shelby. He is also seen assisting in the group numbers Hit Me with Your Best Shot/One Way or Another and I Can't Go for That/You Make My Dreams.
In honor of Santana's coming out, Blaine and Kurt show their support by singing Perfect. Despite the heartfelt performance, Santana insults them and says the song is another thing to add on her list of terrible things. They take their seats, visibly disappointed.
Feeling resentment from Finn, Blaine lashes out at Sam during a glee rehearsal for Sectionals after Sam turned down his idea in favor of selling sex with Blaine insulting Sam by saying he is not for sale. Finn confronts Blaine, who is hitting a punching bag in the locker room, about his fight with Sam. Blaine questions if Finn has a problem with him and Finn replies that he was jealous and intimidated by Blaine's talent. Finn apologizes and the two reconcile. At Sectionals, Blaine performs Control and Man in the Mirror with the New Directions. Despite stiff competition, the New Directions win and advance to Regionals.
Blaine and Rachel perform the original song Extraordinary Merry Christmas for the Glee Club, but Artie requests they sing a more upbeat song for the Christmas special he is directing. Blaine helps co-host the special with Kurt and they both perform Let It Snow before singing a quartet with Rachel and Mercedes in My Favorite Things. The Christmas special ends up being a success. Blaine, along with the New Directions, would later perform Do They Know It's Christmas? at the homeless shelter. In a deleted scene Blaine gives Kurt a promise ring in the school hallway.
Blaine is rarely seen in the episode. He joins the boys in the opening group number, Summer Nights and sings backing vocals in Moves Like Jagger/Jumpin' Jack Flash. When the Glee Club finally decides on a song for Will's proposal to Emma, Blaine performs in We Found Love with synchronized swimming team at Sam's suggestion.
Blaine discusses Sectionals with Kurt, Mercedes, Santana and Brittany before singing Wanna Be Startin' Somethin' as a way to start Michael week when Will states he is thinking of performing Michael Jackson for Regionals. Blaine later has coffee with Rachel, Kurt, Santana and Artie at the Lima Bean, discussing their favorite Michael Jackson memories. After a small heated discussion on Michael's impact on their lives, Sebastian interrupts them out of nowhere and informs them that the Warblers will be performing Michael Jackson songs at Regionals. When asked how he found out about New Directions plans for Michael, Sebastian reveals Blaine had told him, causing a small rift between New Directions and Blaine. When New Directions discuss what happened in the choir room, Will asks them what Michael Jackson would do? After several suggestions, Blaine suggests that Michael would "take it to the streets." Blaine, Artie, Santana and Sebastian lead a New Directions versus the Warblers face-off in a parking garage with Bad, which ends horribly when Sebastian tosses a slushie at Kurt. However, before it can hit him, Blaine intervenes and takes the slushie to the face, falling on the floor and screaming out in pain. Kurt explains to New Directions the next day that Blaine has a scratched cornea and would need surgery. In an attempt to cheer him up, Kurt, Rachel and Finn visit a bed-ridden Blaine at his house, singing Ben to him and bringing him eye-patch themed movies. During the visit, Blaine proposes a toast for Kurt, who found out about his NYADA finalist letter. It is later revealed that the slushie that hit Blaine contained rock salt, which is why Blaine's eye was injured.
Throughout Valentine's week, Kurt receives Valentine's cards from a secret admirer, believing it to be Blaine. However, it is later revealed at Breadstix for Sugar's Valentine's Day party that it was actually Karofsky who sent them because he is in love with Kurt. Despite being flattered by the gestures, Kurt rejects Karofsky because he loves Blaine, prompting Karofsky to storm out. At the end of the night, Blaine makes a surprising return and leads Love Shack with the New Directions.
Blaine's feelings towards Sebastian have drastically changed. Even when Kurt mentions his name, Blaine gets upset. Blaine sings Cough Syrup as a possible number for Regionals. When New Directions catches news of Karofsky's suicide attempt, Blaine joins the Glee Club in the auditorium and discuss what they are looking forward to experiencing in the future. Blaine says he is looking forward to marriage equality in all fifty states. Later on, he, along with Kurt, Brittany and Santana, confronts Sebastian at the Lima Bean over his blackmailing of Rachel, but Sebastian says he has changed because he feels partially responsible for Karofsky's attempt. After this, Blaine begins to forgive Sebastian and even cheers the Warblers on at Regionals. He participates with the Glee Club in Fly/I Believe I Can Fly and the New Directions go on to win Regionals. In an act of good sportsmanship, Blaine shakes hands with Sebastian and the two appear to be on good terms. He is later seen waiting for Quinn at Rachel and Finn's wedding, unaware that she has just gotten into a car crash.
Several days have gone by since Quinn's car accident, Blaine is lamenting his older brother, Cooper, visiting Lima. They meet up at his locker where Kurt instantly becomes enamored with him as he recognizes Cooper from his credit rating commercials. Blaine watches as Kurt and Sue fawn over Cooper and after Cooper is pulled away by Sue, explains to Kurt that this is the reason why he and Cooper do not talk much. Sue introduces Cooper to the New Directions where he is asked to coach a master acting class to help those with a future in the entertainment business.
During the class, Rachel suggests for Blaine and Cooper to perform together and with some pressure from Kurt, a hesitant Blaine duets Hungry Like the Wolf/Rio with Cooper. While the performance was a hit with the New Directions, Blaine is disappointed that Cooper acts like they are applauding for him solely. The two brothers have lunch at Breadstix together where Cooper charms the waitress to give them free Cokes, using a Scottish accent, much to Blaine's annoyance. During lunch, Blaine gets increasingly annoyed with Cooper's criticisms, until he has an outburst, saying that all Cooper does is tell him what he is doing wrong. There is then a flashback to Blaine and Cooper's childhood, showing their troubled relationship. Cooper tells Blaine that despite their age gap, he wants to be closer to Blaine and Blaine nods, seemingly regretting his words.
During Cooper's second master class, Blaine is visibly annoyed with the horrible advice Cooper is giving his friends. While practicing a scene from NCIS, Cooper's constant criticisms become too much for Blaine and they break into an argument with Blaine wondering why Cooper cannot just support him. Cooper then uses the argument as an example for the master class, which frustrates Blaine. In the school hallway, Blaine watches as Cooper take pictures with Blaine's friends and boast about his life. Cooper tells Blaine that he is going to audition for Michael Bay's new movie and is disappointed when Blaine's unenthusiastic about it. Blaine tells Cooper that he is sick of Cooper making everything about him and expresses his frustration by singing Fighter.
Kurt comes by Blaine's locker and tries to cheer him up with a small, dog plush toy. Kurt then gives Blaine advice on siblings and encourages Blaine to make amends with Cooper. Kurt tells Blaine that Cooper has not left Lima yet and is waiting for him in the auditorium. Blaine and Cooper then sing Somebody That I Used to Know before Cooper apologizes to Blaine for being so hard on him. Cooper reveals that he is only like that because he knows that Blaine is talented and will be successful. They make up with each other and Cooper reveals that his audition with Michael Bay was cancelled because they found someone better and/or hotter. They embrace each other again and Blaine tells Cooper that he will help him film his acting to show Michael Bay that how talented Cooper is.
Blaine, along with Brittany and Mike, start off the episode, performing You Should Be Dancing through the school, ending in the auditorium where Blaine reveals that since Nationals' theme is vintage, they thought they could perform disco, to which Will nods in approval. The New Directions however, are not all that enthusiastic about the idea, as they think disco sucks. Nevertheless, Blaine is excited when Will and Sue work together to turn the choir room into a disco hall where they receive their assignment: performing songs from the movie soundtrack of Saturday Night Fever. Blaine, along with Will and Joe, perform Night Fever together as the New Directions have a dance-off to see who will win a replica of the white suit worn by John Travolta in the film. Blaine is later seen enjoying the performances of the finalists, Mercedes, Santana and Finn, as the New Directions close off the episode with a dance number to Stayin' Alive.
After Will reveals to the Glee Club that they will be paying tribute Whitney Houston, Kurt excitedly gushes about what song he will sing while Blaine looks uninterested. After Kurt asks if Blaine can come with him to Between the Sheets, the music store, to help him pick out a song that can double as his glee assignment and his NYADA audition. Blaine, however, declines and tells Kurt to text him later. Unbeknownst to Blaine, Kurt has been texting another guy named Chandler Kiehl and although he claims it means nothing, Rachel points out to Kurt that if he is not willing to show Blaine these messages, then it is not completely innocent. During Rachel and Santana's rendition of So Emotional, Blaine is visibly upset when Kurt ignores him in favor of reading the text messages from Chandler. Later when Kurt and Blaine plan to have a Being Bobby Brown marathon, Blaine looks through Kurt's phone and confronts Kurt about the text messages. Blaine accuses Kurt of cheating, but Kurt denies it and says that it is only texting. He also points out that Blaine used to do the same with Sebastian. After the argument, Kurt tells him that it is okay.
During Glee Club, Blaine decides to publicly humiliate Kurt by accusing him of cheating and singing It's Not Right, But It's Okay as his glee assignment. After the song, Blaine storms out of the choir room. Later, after receiving some advice from Burt, Kurt sings I Have Nothing as an apology and later takes Blaine to "couples therapy" with Emma where the two hash out their problems and make amends. Blaine and Kurt reaffirm their love for each other and hug it out. Towards the end of the episode, Blaine and Kurt are happy again. Kurt tells Blaine that he told Chandler to stop texting and receives a text from Blaine. Kurt invites Blaine for glee practice even though it is not mandatory and says that he wants to cherish the last few glee practices left. They arrive in the auditorium where they sing My Love Is Your Love with Artie and Mercedes as the rest of New Directions join in.
With Kurt and Rachel's NYADA audition looming, Blaine assists Kurt with critiquing his performance of The Music of the Night. Finn calls together the boys of New Directions to help Puck, who is suffering in grades. Puck tells everyone that he ran into his dad and does not want to end up like him, so they guys agree to help Puck study for his European geography exam. Later, Blaine and Finn cheer on Kurt and Rachel as their audition for NYADA. After Kurt puts on a show-stopping performance of Not the Boy Next Door, Rachel unexpectedly chokes during her audition and Carmen Tibideaux, the dean of NYADA, leaves. At three o'clock in the morning in the choir room, the guys of New Directions struggle to help Puck remember the material. The guys then perform The Rain in Spain to help jog Puck's memory. After the taking the test, Puck thanks the guys for his help and says that they all taught him how to be a man, even Blaine.
Class president Brittany is in charge of the prom theme and issues a ban on hairgel because hairgel hadn't been invented yet. Blaine is horrified as he is embarrassed to be seen with his hairgel. Blaine is later seen in the auditorium, singing Big Girls Don't Cry with Kurt and Rachel. The three of them share their discontent on prom and decide to have their own prom, the anti-prom. However, their anti-prom turns out to be a bust and they leave for the prom where Brittany orders Blaine to remove his hairgel. Although hesitant at first, he agrees and his hair ends up making him look like Borat.
Blaine is seen at the mall with Kurt, agreeing with Kurt's stance against Sue's plan of having him cross-dress to face-off against Vocal Adrenaline's transgendered lead singer, Wade "Unique" Adams. Tina runs into the pair and subsequently hits her head on the water fountain. There, Tina enters an alternate reality where everyone in New Directions are switched with another member. Puck is dressed like Blaine while Blaine is dressed like Puck, adopting each other's mannerisms.
The New Directions prepare to compete at Nationals in Chicago. Blaine is a featured soloist in Paradise by the Dashboard Light. After the competition, the New Directions are crowned champions and they return home to the school, following their win. Members of the hockey team approach them with slushies, though it turns out to actually be confetti. By the end of the episode, everyone in New Directions celebrate Will's win for Teacher of the Year by singing We Are the Champions.
As the New Directions prepare to say goodbye to their seniors, Blaine questions Kurt on their future and how Kurt's graduation will impact their relationship. Kurt, however, says that he will never say goodbye to Blaine and imagines a future many years from now with him. Later, as a goodbye song to each other, the seniors, including Kurt, perform You Get What You Give and the juniors, including Blaine, sing In My Life. Blaine attends the graduation with Tina and Brittany to see Kurt off. Kurt ends up not getting accepted to NYADA while Rachel is accepted after Tina helped her set up a re-audition. Even though Rachel says she will decline the offer and apply next year, Finn sends her off on the day they were supposed to get married and New Directions, including Blaine, along with Will and Emma.
The new year sees big a change with New Directions, in personality and popularity. After Jacob Ben Israel asks Artie, Blaine, Brittany and Tina which of them will become the new Rachel, they all simultaneously respond that they will take Rachel's place as lead soloist. When Will introduces last year's MVP Unique from Vocal Adrenaline to the group, Blaine, Tina and Brittany are not very receptive to the idea and Blaine asserts that there is already enough competition for lead soloist. After Unique tells them that she will be the "New Rachel," Blaine declares they have a sing-off. With Artie judging, Blaine, Brittany, Tina and Unique sing Call Me Maybe, with each acting overly competitive with each other. Later at lunch, Artie and Sam exclaim that Unique should not be wearing make-up in public, and Blaine tells her she can be Unique during performances. After some insults are exchanged about the new lunchlady with the new Cheerio, Kitty Wilde, and her football goons, Bobby and Phil, the group are then scolded by Marley Rose, who turns out to be the lunchlady's daughter.

During the performance, Blaine is seen banging on his chest and swinging around on a liana.

Once he notices that, he is embarrassed and tries to get her to stop. She then shows the video around during Glee Club.

That leads him to make "twerking" the week's assignment. He later participates in a presentation Will holds for the school board, dancing with Kitty to present a group of dances Will summarizes as "dirty dancing."

His fiancé doesn't believe him, and pulls him to sit with him on the bed, telling him that he is scared, and that he can't run away from his talent just because he feels nervous, because he has a gift. Blaine thanks him for knowing him, and they share a loving hug.
Blaine, along with Kurt, Sam, Rachel, and Santana, talk at the apartment, with Santana complaining about a piano Blaine bought for them as a thank you for letting him and Sam stay there for the week. They then talk about Sam's new diet and his meeting with modeling agent Bichette, and decide to perform Just the Way You Are to assure him he doesn't need to lose weight. Despite her earlier complaints, even Santana joins in, and Blaine shares looks and smiles with his friends and fiancé throughout the performance. Tina announces that "Blam" is back as the two arrive near the rest of New Directions and Sue at McKinley, and Sam informs them that Blaine crushed his NYADA audition. When Sue tries to continue confronting Will, and despite her complaints, Blaine and the other members and students perform You May Be Right.
Blaine comes into the choir room after Will got caught up in a staff meeting and tries to present ideas for Nationals. Everyone except Jake dismisses him, calling him controlling and bossy. The conversation upsets Blaine as he fails to unite everyone, leading him to sitting in the next room acting like an upset child. He calls and complains to Kurt afterwards; Kurt reminds him that Glee Club is about equality, but also accidentally calls him a 'puppet master'. He changes the subject to Pamela Lansbury's debut gig and asks Blaine to fly to New York to see it. Blaine agrees before proceeding with his complaints.In the choir room, he complains to Brad about his problems before settling in the back corner and accidentally inhaling gas leaking through the vent, leading him to a daydream about everyone being puppets and encouraging him to show his greatest potential. Blaine performs You're My Best Friend the puppets until the real Tina snaps him out of his dream. Sam and Kitty then complain about him being quiet during the entire practice and his pity party. He then runs into Jake in the halls and tells him to sit in the back corner. He does and dream-performs Nasty/Rhythm Nation.
Later in Arts and Crafts class, Blaine asks the teacher for permission to use the materials to make a puppet version of his fiancé. Though permission is given and the doll is made, it is soon yanked away by Sue, who warns Blaine not to put his hand in butt of any puppet, or he will be in a world of trouble. He tries to steal it back after school, but Sue catches him and sends him to detention, which forces him to miss Kurt's performance. He calls Kurt minutes before the performance and gets scolded (both by real Kurt and puppet Kurt). The next day in detention, he has another puppet dream of Jake and Becky. He has a conversation with the two before the real Jake snaps him out of it.
He makes a Tina puppet to cheer himself up, but Tina catches him. She comes to tell him that the others feel bad about their behavior towards him and agree to let him have at least one solo number in one of the Nationals songs. He hands the Tina puppet to Tina, then sends a new Kurt puppet to Kurt as an apology, and also sends puppet versions of Rachel, Santana and Starchild; In Glee Club, he apologizes to everyone for his behavior and then presents a doll version of each and every one of them, ending the episode with The Fox.
At the end of the Glee Club meeting Blaine starts singing Joy to the World, but all the New Directions' members tell him to shut up. In the McKinley High Non-Denominational Christmas Club he comments how the Club looks a lot like Glee Club, as all the New Directions are part of it. Later he is seen decorating the Christmas tree with the others, and humming O Christmas Tree when Sue comes to judge their tree. He enjoys watching the performance of Mary's Little Boy Child. At the next Christmas Club meeting, after Marley tells them that Kitty think she's not worthy of the role of Mary, Blaine seems shocked and asks Marley if she understood her correctly, thinking that Kitty might have been snarky. He then suggests that if they make Kitty accept the role, she might stop being so horrible. At the rehearsal he dances dressed as angel Gabriel. He is seen in the living nativity at the end of the episode being one of the shepherds. When Becky joins them, he compliments her Baby Jesus costume.Whenever I Call You Friend with New Directions in the choir room. Meanwhile, Blaine has a phone call with Kurt, who worries about his band, Pamela Lansbury, being taken over by bandmate, Elliott. Blaine gives him advice and tells him to keep his friends close and his enemies closer. While then, Blaine is mentioned to have a solo at Nationals for being "The New Rachel." Later on in the episode, due to Tina and Artie's speech-off for valedictorian, Blaine is considered the new valedictorian - which angers both Tina and Artie. Blaine feels guilty and tries his hardest to apologize to them about the situation. Meanwhile, Becky shows Blaine a "Pamela Lansbury selfie" from Kurt and Elliott as she assumes Blaine and Kurt broke up. However, Blaine denies it and believes the selfie is just for friendship. In the choir room, Blaine tries to request singing a song with Tina and Artie instead of giving a valedictorian speech. Therefore, he sings Breakaway with the three and New Directions altogether in the auditorium.
Blaine, along with Sam and Tina, performs Jumpin' Jumpin' in the Choir Room. It is the first time they do a song together, even though they have been good friends. When Tina breaks down crying after the song, Blaine and Sam comfort her.Later that day, Blaine is trying on his graduation robe, together with Sam. Tina walks in on them and starts crying again. When Tina tells them she's afraid she'll never hear from them again, Sam promises her to send a Vine of him doing an impression every week. Blaine says they should do something to remember their senior year by, and they all agree on organizing an overnight lock-in.
At night, Sam, Blaine, and Tina climb through the Choir Room window to get into school. As soon as they're all inside, they start singing Don't You (Forget About Me). During the performance, they do lots of crazy stuff, like rollerskating around the halls, dancing with each other and messing around in various school offices. They get caught by Becky, who is eager to play Twister and drink energy shots with them. Blaine, along with Sam and Tina, doesn't seem to be too excited for this plan.Later on, Blaine is playing Twister with Becky, who is obviously flirting with him. Sam and Tina left them, and when the game is over Blaine tells Becky he is gonna walk his cramp of and goes looking for them. He ultimately finds them in a classroom, where they are making out. They are both startled by him, and abruptly break their kiss. Tina says it happened because of the 11-hour energies, and Sam adds it was cheap, sordid nostalgia as well. Blaine is shocked, blames them for ruining the night and runs away.
The next day, Blaine is walking in the hallways of McKinley when Sam and Tina run after him, trying to apologize to him. Sam tells him that they just tried making out, and that it was hot, but they both decided they don't want to be a couple. However, Blaine doesn't accept their apology. He explains that he wanted to have a fun night with the two of them, but instead they made it all about themselves and shut Blaine out. He didn't want to feel like a third wheel, suggests they just hang out by themselves that night, and fondle each other's boobs. After he walks away, they are left confused.When Blaine enters the Choir Room the next day, Sam and Tina are waiting for him. They come up to him and are shown to be regretful. Blaine tells them he's sorry about freaking out, and he now realizes that they will be friends forever. They all agree to that and hug each other. During Glee Club, Blaine wants to do a final number with the seniors, and Sam invites Artie to be a part of it. The four of them then perform Hold On in the auditorium.
Blaine sings I Love LA with the other New Directions Boys, on their way to Nationals in Los Angeles. He is the first one to recognize their competition, Throat Explosion and their leader Jean Baptiste in the hotel lobby. At night, he joins the rest of the Glee Club to the Nationals stage, telling them he did things like that all the time with the Warblers.When Sam confronts Throat Explosion about the stolen Finn plaque, Blaine quickly follows him out to support him. Blaine tells him that they're just trying to psych them out, and they should let it go and focus on winning the competition. Blaine and Tina open their Nationals with their More Than a Feeling duet. He sings back-up and dances to America and has solo lines in I Still Haven't Found What I'm Looking For, with the other seniors. When it's announced they came in second place, he's just as disappointed as the rest.
Back in Lima, Blaine and Sam are hanging the Finn plaque back on the wall, which was given back to them by Jean Baptiste.
100 As Glee club is coming to an end, Blaine and the rest of New Directions and the alumni come together to celebrate everything the club has meant to them over the years. Will gives everyone the assignment to re-do songs that the club has performed in the past, but with a new twist. Will also announces that April will be joining them. April has brought along a bottle of sparkling cider and champagne glasses to kick off the celebration and suggests they perform Raise Your Glass. Blaine points out that it was actually the Warblers, not New Directions that did Raise Your Glass. April honks Blaine's nose and says that she always had a soft spot for "prep school boys." Blaine joins in with the rest of the group in singing and dancing as Will and April start off the performance. As Rachel, Kurt and Mercedes perform Defying Gravity Blaine is seen sitting in the audience, cheering his fiance on. Later, April tells Blaine and Kurt that she heard about their engagement and congratulates them. April gives Blaine and Kurt flasks of alcohol as a wedding gift. She does, however, warn them that young couples that marry often end up getting divorced. After Sue has uncovered April's shady financial situation, which results in her no longer being able to fund the auditorium for New Directions, April brings in Holly to lift the Glee Club's spirits with the song Happy. Blaine and Mercedes sing and dance along and the rest of the group joins in as well.
We first see Blaine, together with Kurt entering the Choir Room enthusiastically. They can't wait to share their big news with Artie, Rachel, Sam, and Tina, telling them Blaine got into NYADA. Their friends are all very excited, with Tina stating they're all going to New York. Sam accidentally hits Tina with the trophy he was wearing, which leads her to having another dream. During the New York skit, Blaine is living together with Kurt and they both work at the Spotlight Diner.Blaine is in the auditorium, with the rest of the old and present New Directions, listening to I Am Changing. He is also seen dancing to Holly's performance of Party All the Time, together with Kurt, Mike, Puck, Quinn, Rachel and Will. Later on, he is hanging out with Artie and Sam in the Choir Room, when Tina comes in to tell them she didn't got in Mitzvah University. They try to convince her that she doesn't need a university to go to New York, by singing an acoustic version of Loser Like Me together.
Later that day, Blaine is in the Choir Room again, watching Rachel and Santana perform Be Okay, and Puck and Quinn perform Just Give Me a Reason. He is sad when Mr. Schue tells them Glee Club is officially over. Later that week, he performs Don't Stop Believin' with the rest of the alumni and present New Directions, for Mr. Schue. At the end of the episode, Blaine graduates together with the rest of the seniors and Brittany.
This episode opens a few months after Blaine's graduation. Blaine, Artie, Sam and Kurt meet Rachel in the center of New York, singing Downtown. She offers them lunch as a thank-you for being so supportive during her out of town Funny Girl run, and they gratefully accept. He and Kurt accompany her in her town car.The next day, Blaine makes Kurt a pancake breakfast. Kurt remarks that since they have started living together they have become like an old married couple, but Blaine disagrees, singing You Make Me Feel So Young and Kurt joins in. As the song finishes, they begin to have a romantic moment, but are awkwardly interrupted by Sam. With pressure from Kurt, Blaine agrees to talk to Sam about moving out.
Later he comes home to find Sam playing video games, which he has apparently been doing all day. Blaine encourages him to be more proactive in finding a job, and tentatively brings up the subject of him moving out. He encourages Sam to face his fears and embrace change, and despite Sam's reservations, takes him to Times Square where they sing Best Day of My Life and dance with several street performers. Blaine tells Sam if he can sing and dance in the middle of Times Square, he can pretty much do anything. Sam agrees that it is time for him to "conquer the city." At NYADA, Blaine covertly joins Kurt's mime masterclass. Kurt is shocked, and begins to feel like Blaine is infringing on his need for some personal space. Later, back at the loft, Kurt attempts to comfort Artie after his mugging in the subway, but is interrupted by Blaine loudly using a SodaStream machine which raises the tension even more.Rachel comes home with a diva attitude and asks Blaine to make her some lemon water which he agrees to do. Evidently irritated with both Blaine and Rachel, Kurt leaves the apartment.Blaine decides to make some changes in the apartment, and starts taping off areas to set up a workspace. He reveals that he doesn't quite feel at home at the loft, since it was originally Kurt and Rachel's apartment, and he craves his own space. Sam comes home and informs Blaine that he took his advice and has landed his first modeling gig and will be moving out. Blaine seems sad to see Sam go, but is also very happy for him and the two share a congratulatory hug. When Kurt comes home, he is immediately furious with Blaine for rearranging things in the apartment without consulting him first. He calls the workspace “hideous," and refers to the loft as his home, rather than a space they are both sharing. Blaine retaliates by pointing out that not all of Kurt’s design decisions are brilliant. Kurt says that Elliott was correct about their needing boundaries in the relationship, which makes Blaine angry. Kurt demands that Blaine put everything he moved back in its proper place, but Blaine tells Kurt to do it since it's “his apartment”. He leaves and goes to Elliott’s loft to confront him. He accuses Elliott of trying to “steal” Kurt away from him. Elliott remains level headed and reassures Blaine that he is not after Kurt, and only thinks of him as a friend. He also says that Kurt is clearly in love with Blaine, as he talks about him all the time. Blaine apologizes and comes to realize that some boundaries in a relationship is healthy. The two have a jam session to relax and clear their heads.
Blaine returns home to apologize, telling Kurt that Elliott is a good friend. He reveals that he didn't come home right away because he needed some time to think, and Kurt says he has also been doing the same. Blaine tells Kurt that he thinks he should move out, so they can take a step back to evaluate the situation. Kurt initially fears that the move will be a step back in their relationship, but Blaine assures Kurt that making the decision together will actually make them stronger. They reveal their plan to the rest of their flatmates, and Blaine decides to move in with Sam at Mercedes' apartment, an arrangement that everyone seems happy with. Later, as Rachel sings People at her Funny Girl rehearsal, Blaine and Kurt are seen walking hand in hand enjoying some much needed alone time together after which they have dinner with Sam, Mercedes, Rachel and Artie.
Blaine, Kurt, Rachel and Sam attend a candlelight vigil for Russ, a NYADA student who was a victim of a hate crime because he was gay. As Blaine, Kurt, Rachel and Sam walk to where the crowd has gathered for the vigil, they sing No One Is Alone. The next day, at the Bushwick loft, Blaine, Rachel, Artie, Kurt, Mercedes and Sam have gathered for their weekly potluck dinner. The recent "gay bashing" of Russ is brought up. Mercedes, who did not know Russ, asks what happened. Blaine explains that Russ was beat up by strangers, but luckily survived the attack. The group continues to discuss the prevalence of hate crimes toward people who are gay, and how they seem to be increasing in NYC. Kurt suggests they change the subject before "everyone is too bummed to eat." The discussion turns toward the upcoming Mid-Winter Critique at NYADA, the assignment being to perform Sondheim songs. Blaine, Rachel and Kurt seem excited about the assignment.
Blaine and Rachel decide to perform a duet for the Mid-Winter Critique and select Broadway Baby. Carmen Tibideaux sits with her arms crossed during the entire song and she appears displeased. When Blaine and Rachel have finished, Carmen tells them that they did not follow the directions of the assignment, as they were supposed to perform individual songs. Carmen also accuses both of them of feeling "above their classmates." Carmen threatens to fail them, but then changes her mind because she feels the performance was a good one and offers them the opportunity to re-do the assignment at a later time. Later, at the Bushwick loft, Blaine tries to comfort Sam who is upset after Mercedes tells him she won't date him because he is white and she is black. Blaine offers to read Sam some Star Wars fanfiction, which is apparently something that helps Sam sleep. Blaine then gets the phone call from the hospital informing him that Kurt has been hurt. Several scenes are shown of Mercedes, Rachel and Artie getting the news as well.
At the hospital, a visibly upset Blaine attempts to get information regarding Kurt's condition. Rachel, Sam, Mercedes, and Artie are also there. A doctor emerges and informs the group that Kurt has been sedated with morphine due to his injuries, but will recover. The doctor also tells them that Kurt is unconscious, but they can visit him. Rachel mentions that she feels guilty about leaving Kurt by himself after an argument they had earlier. Blaine reassures her that the outcome would have been the same if she had been with Kurt and that it is not her fault. Blaine, who says he wishes Kurt knew they were there, begins to softly sing Not While I'm Around. As if on cue, the rest of the group leaves the hospital room so Blaine can be alone with Kurt. After he finishes the song, he lays beside Kurt and gently caresses his face. It is revealed that Blaine also performs the song for his Mid-Winter Critique. After Kurt gets out of the hospital, he and Blaine return to the place where the vigil was held for Russ. Blaine tells Kurt that Russ, who was apparently in a coma, woke up and will recover. Kurt places some roses on the memorial. Later, Blaine, Kurt and the rest of the group are having yet another Monday night potluck dinner. Sam and Mercedes announce they are dating, much to the surprise of everyone. Blaine proposes a toast to Kurt in support of his upcoming performance for the Mid-Winter Critique. Blaine is last seen smiling proudly as Kurt performs I'm Still Here for Carmen Tibideaux after which he and Kurt, Burt, Rachel, Sam, and Mercedes share a group hug.
Blaine first appears in a WWII era STD PSA (Public Service Announcement) along with Kurt, Artie and Sam.Next, Blaine is seen walking around and enjoying the city, especially various ethnic cuisines. Blaine reveals that his favorite discovery food wise in the city is the "cronut"-a dessert which is a cross between a donut and a croissant. Unfortunately, Blaine discovers his recent indulgences have led to him gaining the dreaded "Freshman 15" as he is having trouble fitting into his clothes.
At NYADA, Blaine and Kurt are taking a stage combat class. While Kurt seems to excel in the class and has clearly been working out and taking care of himself, Blaine sits nearby, (snacking on cheese puffs) watching Kurt and reflecting on the situation. It seems that Blaine has been feeling out of sorts since coming to NYC and reveals that while he is proud of Kurt's accomplishments, he is also feeling a little jealous and uncomfortable with Kurt being regarded as a "sex object." Later, Blaine and Kurt meet Artie and Sam at Serendipity for some guys bonding time. Sam mentions that he and Mercedes have not had sex yet and that he would like to get tested for STDs to ensure he has a "clear bill of health" should the time come. In the spirit of camaraderie, the rest of the guys offer to accompany Sam to the clinic to get tested as well. They toast the occasion with frozen hot chocolates which Kurt expresses reservations in eating due to his recent health kick, but Blaine encourages to go ahead and eat it anyway.At the Bushwick apartment, Artie confesses to Blaine, Kurt, Sam that he has contracted Chlamydia although he isn't sure how. Blaine asks Artie if he uses condoms. Artie confesses that he doesn't, which Blaine says explains the situation. However, when Sam starts to "slut shame" Artie, Blaine requests that he calm down as Artie clearly feels bad enough. Blaine does tell Artie that he needs to inform the women he has been sleeping with recently, for the sake of their health. Artie later takes Blaine's advice.
Back in stage combat class, Blaine once again struggles which Kurt picks up on. However, Kurt assumes Blaine's recent decline in confidence has to do with the move to a new city and other changes and notes that he and they as a couple are being tested. When the two meet up at Mercedes' apartment, Kurt suggests a date night so they enjoy some alone time, which Blaine cheerfully agrees to. However, tensions arise when Blaine mentions he has cooked a decadent meal for the two.Kurt says they shouldn't eat it because it's rather heavy and that he would rather they get salads out instead. Kurt then finds an adult website on Blaine's laptop while searching for movie playing times. Kurt appears to be hurt by the content and mentions that they haven't been intimate in at least a week. Blaine offers an explanation, but Kurt doesn't want to hear it and leaves the apartment. The next day, Kurt and Blaine are in combat class again. Blaine questions why Kurt left the diner before Blaine got there, as they were going to walk to class together. Kurt says that he simply forgot to tell him he got off work early, but it seems that Kurt blew Blaine off because he is still angry about the adult website he found on Blaine's laptop. Blaine tries to talk to Kurt about it, but he refuses, saying that they talk too much. As combat class starts, Kurt and Blaine sing Love Is a Battlefield. Blaine continues to struggle throughout the class.
At the Bushwick apartment, Kurt comes home to meet Blaine. They have a discussion about the recent tensions between them. Blaine admits that earlier in their relationship it made him feel good to be able to help and "protect" Kurt and now in the present he feels as if Kurt is pulling away from and him and he is not needed. Blaine also admits the reason he has been using the adult website and they have not been intimate in some time is due to his feeling insecure. Kurt tells Blaine that he would never judge him, but he also won't apologize for his recent accomplishments or for not being a "delicate flower." Blaine confesses his fear that Kurt will stop loving him if he continues to change. Kurt tells Blaine that would never happen and pleads Blaine to talk to him the next time he is feeling that way. In the final scene of the episode, Blaine is with Kurt, Artie and Sam at Serendipity again. Blaine reveals he is going on a diet to help lose some weight. Kurt and Blaine have agreed to eat home more often and cook healthier meals. Since Mercedes has told Sam him that she needs to wait until she is married to have sex, (which he agreed to) Sam suggests they all partake in a guys' absence club, which Blaine and the other guys reject.
He is first seen in Rachel's nightmare watching her performance and dancing. Next we see him in the apartment when Tina comes to visit, and he tries to stop Tina from talking about the negative comments about Funny Girl that bother Rachel. Next day he comes to the apartment along with Sam, Mercedes and Tina, and tries his best to make Rachel feel better so she could go on stage that night. After they all fail at cheering her up, he talks to others commenting that it's weird of Rachel to behave this way because she usually pushes people away to get on stage. He is shocked when Sue comes into the apartment and takes Kurt's room without even asking for permission. When Santana manages to cheer up Rachel, he participates in the group hug.
He watches Rachel's opening night and enjoys her performance. After the show Blaine and the others congratulate Rachel on her Broadway debut. When she says she doesn't want to go to the cast party, Blaine suggests a club in Greenwich Village. He has fun with his friends and can be seen dancing a lot in the club. The group comes back to the apartment early in the morning. When Tina mentions she got the DJ's number and shows the paper with the number, Blaine tells her the DJ was clearly gay and takes the number away from her. After Rachel's confrontation with Sue, Blaine claps to show how great Rachel was at standing up for herself. When the group gets to the newspaper stand and buys The New York Times he is both nervous and excited to hear what the critic thought of the show. He reads a part of it, visibly happy that it's good news. When Mr Schue calls Rachel, he's glad to hear everything is fine and that Mr Schue now has a baby boy.
We first see Blaine waiting outside of NYADA for Kurt, who tells him about the latest news that June Dolloway is gonna visit the school. Blaine doesn't know who she is, but is excited once Kurt enlightens him and tells him Kurt was picked to perform for her. Kurt then tells Blaine he wants him to join the performance, by singing Story of My Life together, which Blaine happily accepts.Later that week, they both perform Story of My Life for June Dolloway. June is happily surprised when she hears Blaine singing. After the performance, she tells him she thinks he's extraordinary and wants him to accompany her to an event next week. They both first think she's talking about Kurt, who is excited to hear this, and are surprised when she tells them she meant Blaine.
Kurt is helping Blaine to get ready for the event later, when Blaine tells him he should just stay home with him. Kurt, however, tells him to stop it. He admits to being a little jealous, but states he's not resentful. He tells him to have fun and don't worry about him. Blaine then joins June to an event which includes a lot of rich people. June tells him they have to be friends if she's going to launch his career. She explains she has to know him really well, to be able to serve him. When June isn't satisfied with the two million dollar they have raised so far that evening, she goes up on stage and also invites Blaine over. They sing Piece of My Heart together, while collecting money.
Blaine joins June for dinner again later that week, where she announces they are going to do a show to showcase his talent. Blaine is very flattered and excited, but tells her that he would love to have Kurt in the show as well. When June denies his request, Blaine tells her he thinks he can't do it. She then advises him to break off the engagement at all. Blaine reacts shocked, but she explains love isn't everything in life. It's just what humans do: fall in and out of love. But he needs to break it off in order to realize his full potential, according to her. At home, later that week, Blaine spends some time with Kurt for the first time in days. It is revealed that Blaine hasn't told anything about June to him. When he tells Kurt about the show, he is very excited for him, but is also confused as to why he didn't say anything about it. Blaine doesn't know how to tell him te real story. Instead he tells him he didn't say anything about it, because he wanted to work out Kurt's part more first, which makes Kurt even more excited. Blaine, however, is shown to have mixed feelings.
Blaine is first seen having dinner with Kurt, Rachel and Santana. When Kurt asks if anyone wants to catch a matinee, Blaine apologizes saying he doesn't have the time as June has him busy with dinners and rehearsals. He seems interested in Rachel's public image problem, but also tells her she's lucky the producers of Funny Girl don't know she's thinking of leaving. When Santana suggests a publicist, Blaine responds that Rachel can't afford one. He later helps Rachel build a good public image, first by pretending he's a random person on the street that noticed Rachel Berry, the Broadway star, in front of paparazzi, and later by performing with the others at her charity event.
Blaine helps Kurt with his costume before the show, and then watches him perform Lucky Star as Peter Pan. After the show he congratulates Kurt on a great performance, and then, on the behalf of the charity "Broadway Bitches," invites the old Broadway stars from the retirement home to perform with them at the charity event that evening. We last see him at the event singing Take Me Home Tonight during which they give the dogs from the shelter to people.
At the Bushwick Apartment, Blaine helps Kurt and the others get ready for their evening meal together. Excited about the arrival of screenwriter Mary Halloran, Kurt whispers to Blaine that they have to find a way to get her to attend their showcase. Blaine agrees, unconvincingly - he still hasn't told Kurt that June refuses to let him be a part of the showcase. When Mary arrives, Blaine is taken aback by her eccentricity. As she rushes to the bathroom, he and the housemates watch, bemused. At NYADA, Blaine is getting ready for his showcase. June arrives with food, and gives him some advice on show-business. Blaine is clearly distracted, and confesses to her that he is worried about his lie to Kurt - he has told him he will have a place in the showcase. He begs June to let him have just one line, but June refuses. She tells him that her reputation is on the line - and she cannot jeopardise her track record over Kurt. Blaine persists, but June beats him down with a profound and ominous saying before leaving.
Blaine performs All of Me in sadness at his misleading of Kurt over his place in the showcase. At the end, Kurt enters, and applauds his performance. He asks if he's planning to put it in the showcase - but Blaine flatly admits to Kurt that June doesn't want him the showcase, cutting him short. Kurt is shocked by his blatant lie, and angrily shouts at him. Blaine begins to apologise, but Kurt walks out, furious. Later, Blaine attempts to be interviewed by Mary, but is distracted by the fact that she's lying under a table. In frustration at her ridiculous questions, he begins to doubt her legitimacy. He later joins the group back at the apartment for the first read through of the 'Untitled Mary Halloran Project'. In the script, he has become 'Slaine' - an art exhibitionist who has recently started an affair with 'Nittany'. The group are forced to stop reading due to the scripts sheer awfulness - and Blaine urges Rachel to speak with Mary about it.
Outside NYADA, Kurt joins Blaine, who is feeding pigeons morosely. Blaine admits that he doesn't want to do the showcase any more - Kurt is more important to him. Kurt wonders what it's like to fly for the first time, and tells Blaine that relationships are like that - you never know what day the person you've given your heart to will drop it like a stone. Blaine begins to apologize once again, but Kurt stops him, telling him that he's not angry with him. He explains that trust is a choice - and he has chosen to trust Blaine, no matter if he slips up now and again. They hug, and Blaine tells him that he's getting a little turned on with all the bird talk. They retreat inside. At the showcase, Blaine performs No Time at All with June, to an adoring audience. Cheered on for an encore, he thanks June for teaching him to have passion in his work, and explains to the audience that he has chosen his last song to express his passion about his fiance. He invites Kurt onto the stage to perform the song with him. June is clearly horrified, but can do nothing as Blaine takes him by the hand and leads him onto the stage.They perform American Boy to a cheering audience. At first, June watches, unimpressed, but she slowly begins to get into the performance, and by the end joins the flatmates on stage, dancing along. At the end Blaine starts to apologize for singing with Kurt, but June stops him. She tells him never to let anyone - not even her - cause him to doubt what he is sure of.
The next day, Blaine and the group stand in the streets of New York, admiring Sam's 'Treasure Trailz' advert. Rachel reflects on the past year, and they all agree to meet up back in New York in six months time - come what may. They have a group hug. Blaine and the others perform Pompeii through the streets of New York. As they song plays, there is a shot of Blaine arriving at the apartment, suitcase in hand, having just moved in with Kurt. Later in the song, Rachel gets a call from the network. She reveals to Kurt and Blaine that they love the script - and want to make it into a pilot. Realising that she's going to LA, they hug each other, jumping for joy.
Blaine reunites with Rachel at the Lima Bean six months after the end of the fifth season. He explains how he and Kurt broke off their engagement, which depressed him so much, he dropped out of school. He returned to Ohio and became the coach of the Warblers. Seeing Rachel going through the ringer herself, he sings Suddenly Seymour with her.
Blaine attempts to start new by going for a different style, but realizes, after a poor reception to his knew look, that he doesn't need to change a thing about himself. Afterwards, he meets female student who wishes to join the Warblers. He seeks the advice of his friends, who tell him to give the girl a shot despite his reservations because the Warblers are traditionalists.
He eventually concedes and allows Jane to audition, much to the dismay of the Warbler Council. Jane gives a knockout performance, but she is rejected by the Warblers anyway. After the decision has been made, Blaine attempts to protest by giving up his job as coach in support, but Jane decides to defect to New Directions. Blaine is angered by this and accuses Kurt and Rachel of "poaching", declaring war.
Blaine is last seen snuggling with Karofsky at the McKinley homecoming, watching the fireworks as Kurt looks on with sadness.
Blaine runs into Kurt at the music store while Kurt is looking for sheet music. As it turns out, he's also there with Karofsky, making the moment extremely awkward for all parties. After Blaine leaves, Kurt fantasizes about singing It's Too Late with Blaine all over town.
Later, Brittany and Kurt have a conversation where it's revealed that he is moving in with Karofsky. During Jane and Mason's performance of Will You Still Love Me Tomorrow/Head Over Feet, Kurt begins to reminisce about all the times he had with Blaine.
