The Mercedes-Shane Relationship was the formerly romantic relationship between Mercedes Jones and Shane Tinsley. They are commonly referred to as Shanecedes. The two meet and start dating during the summer break, after Sam moved out of the state. In Heart, Shane and Mercedes break up due to Mercedes feeling guilty about kissing Sam and telling Shane about it. They still appear to be on good terms.
During Mercedes' interview with Jacob Ben Israel, Shane is shown to be very confident and encouraging of his girlfriend's dreams. Additionally, during New Directions' performance of We Got the Beat, Mercedes is mostly dancing around Shane, and he seems to be thoroughly enjoying her presence. Unlike most of the students in the cafeteria, Shane appears to like the group's performance, and smiles broadly.

Also, when the girls perform The First Time Ever I Saw Your Face, Mercedes pictures Sam's face instead of Shane's.
Shane finds out about Sam and Mercedes and is seen to be upset. According to Mercedes (who tells this to Sam later on) he felt like she 'punched him in his heart.' The couple splits up. Mercedes and Shane both cry, but Mercedes sings I Will Always Love You to Sam, showing her feelings for him are stronger than her feelings for Shane.
During senior prom, Shane and Mercedes attend prom with different people but during Love You Like a Love Song they are seen looking over at each other, smiling, showing that they were happy for one another and they wave to each other.
