This episode stages Dani's debut on the show. She is a waitress at the Spotlight Diner, where Santana, Rachel and later Kurt work as well. Dani was first seen taking orders from a customer when she sees Santana staring at her, causing the latter to blushingly look away. Her first scene is a talk with Santana about their comeouts. Dani tells Santana that her parents hated the idea of Dani being a lesbian and how after a big fight with them (due to their finding her making out with a girl in their basement) she took her guitar and never looked back. Santana tells Dani that her parents were okay about her being a lesbian, but her grandmother wasn't, and about Brittany. After hearing this, Dani tells her she needs someone new and acts very flirty towards her.
We see Dani again in another scene, when Rachel leaves the diner early to leave Santana and Dani alone. Santana asks if Dani shouldn't be going too, to which Dani replies that she likes to stay at the diner to watch the sunrise. Santana admits she never did it, so she stays with Dani and this leads to their performance of Here Comes the Sun, which ends with them reaching Dani's house. After it, they said goodbye and share an innocent first kiss.
By the end of the episode, Santana and Dani are officially dating. Santana invited her back to the loft where she, Rachel and Kurt live. Rachel, Kurt and Santana all have parts in Let It Be, however, Dani does not even sing though she is seen during the performance.
Dani got excited when Kurt mentioned that he is starting a band and asked if girls are allowed to join. He said yes and wanted Dani, Santana, and Rachel to sign up to spare him the agony of open auditions. Dani agrees to join, Rachel passes. Dani then asks her girlfriend if she'll want to join and Santana agrees to join, wich makes Dani really excited, but Santana says she'll only join if they get to help with the setlist and have a say in who joins; Kurt agrees. At the auditions, she's sitting on a platform, bored and she asks how long do they have to wait here. When Elliott shows up she is impressed by his clothes and tells him that he looks "freaking badass". When Starchild performs Marry the Night she plays the guitar and is impressed by his singing voice. When he's finished, she congratulates him because she was really enjoyed his performance.
Dani is seen at the loft with Kurt, Santana and Starchild trying to come up with a name for the band. She suggested "The Nipslips" and added that boob lovers of all genders would show up, but the name was shot down by Kurt. Rachel jokingly came up with the band name, "Pamela Lansbury," and they all agreed. She is happy when Rachel agrees to join. To mark the beginning of Pamela Lansbury she and the rest of the band perform Roar.
Dani is having a meeting with Pamela Lansbury where she is seen lying on the couch next to Santana, in which Kurt tells them about their debut gig. They are excited until they find out it’s at Callbacks. Dani, Elliott, and Santana don’t think it’s the best place to have their first performance, but Kurt insists to perform there and shuts down Dani's input. She is then seen in Kurt's vision of the band performing Into the Groove in which she is seen playing the keyboard.
She is later seen at Callbacks with the rest of the band, but there is only one person in the audience. She and the others are disappointed and retreat backstage. It is assumed that the band still perform off screen because at the band's second meeting of the week (which Dani isn't present for) Kurt explains how their sole audience member helped to set up the band's second gig at the Music Hall of Williamsburg after watching their show.
Since Rachel and Santana keep fighting when they are in the Bushwick apartment with Kurt, he tells them they are out of Pamela Lansbury and that he is disbanding the band to start a new one with Dani and Elliott. Santana, surprised, asks if her own girlfriend agreed with kicking her out, and Kurt responds Dani only wants to have fun and sing, and that she knows it is impossible while they are still in the band.
She is finally seen during One Three Hill's (the name of the new band) first gig at Callbacks, performing The Happening and having fun, she is also seen making eye contact with Santana in some parts of the song. Later, Dani is seen entering the Bushwick Apartment with Kurt and Elliott when Santana and Rachel were talking about their friendship status. When Santana tries to leave she asks her to stay so she can feel less guilty about agreeing with Kurt kicking her out of the band, but fails and says goodbye to her girlfriend with a kiss. She is last seen performing Hold On with One Three Hill as Santana and Rachel didn't make things up.
Brittany mentions Dani after kissing Santana by saying: "I'm sure your girlfriend's great, but you can't recreate what you and I have".
Dani is not mentioned at all in this episode, but as Santana and Brittany got back together, it can be assumed that in some moment between 100 and this episode, Santana and her broke up.
Kurt mentions that One Three Hill has been on a hiatus ever since Dani's Roller Derby team became state champions.
