Rachel offers Quinn some vocal coaching in order to ensure New Directions' strength against the Trouble Tones. Quinn says she's ok especially since the Trouble Tones won't be a threat once they lose Shelby as their coach. She tells Rachel about Shelby's relationship with Puck but warns Quinn to be careful about spreading the information. Even though Shelby is a teacher, Puck is 18 which means that their sleeping together is legal but if Shelby is fired she won't be able to provide for Beth. What Rachel doesn't know is that this is all part of Quinn's plan. If Shelby is seen as an unfit mother it will make the custody battle much easier for Quinn.

She says that she didn't really appreciate him when he was there. Ultimately, she wants him to be with her to improve her image in the quest for Beth. He turns her down saying that he doesn't want to be a part of her rich girl problems. Mike shocks Tina when he tells her he applied to medical school in the hopes of keeping his family happy. She tells him he doesn't need to make everyone happy and that he should follow his dreams. If he's not committed to following them then she thinks he should just go ahead and become a doctor. He counters by telling her that perhaps his father was right after all and that they shouldn't be together.
At practice, Sam thinks that Blaine's dance moves are too boy band and he throws in some moves from his strip club routines. Everyone likes the results but Blaine thinks that the tactic is cheap.
