Open with Mercedes (Amber Riley) and Sam (Chord Overstreet) singing "Summer Nights" to their friends in reference to their former relationship.

We get a voiceover (by Helen Mirren) of Becky's thoughts. She tells us she's looking for a new man and is very interested in Artie (Lauren Potter). She tells Sue (Jane Lynch) how she's feeling. Sue tells him she should ask him out.

Beiste (Dot-Marie Jones) tells Emma (Jayma Mays) and Sue she eloped with Cooter over the holiday. The discussion turns to whether or not Will wants to marry Emma. The women tell her she should ask him herself. Emma sings "Wedding Bell Blues." Afterwards, he asks if that was a proposal. She kind of stutters.

Wills tells the class their assignment this week is to find the perfect song/performance for him to use when he proposes to Emma.

Sam is still pursuing Mercedes. He wonders if the reason she's dismissing what they had is because he's not an athlete.

Artie (Kevin McHale) asks Sugar (Vanessa Lengies) if she will work on a song with him. She misunderstands and turns him down for what she thinks is a date. Immediately afterwards, Becky (Lauren Potter) walks up and asks Artie out. He says yes.

Beiste tells Sam the only varsity sport he can still get on is synchronized swimming. We meet head coach Roz Washington (guest star NeNe Leakes). Joining synchronized swimming does not have the desired affect for Sam, as ice hockey guys slushy him together. Mercedes immediately begins wiping him off, to Shane's annoyance.

Artie thinks Will should dance will his proposal, which leads to a performance of "Moves Like Jagger" combined with "Jumping Jack Flash." Watching this was supposed to be Artie's date with Becky. She asks for a more traditional dinner at Breadsticks.

While shopping for rings, Will asks Finn (Cory Monteith) if he'll be his best man. Finn tells him he's spoken to an Army recruiter because he wants to follow in his father's footsteps.

Rachel, Santana (Naya Rivera), Mercedes and Tina (Jenna Ushkowitz) ask Will about the first time he met Emma. The girls perform "First Time Ever I Saw Your Face," with each thinking about the respective loves of their lives (Finn, Brittany, Sam, & Mike). Interestingly, Mercedes thinks of Sam rather than current boyfriend Shane. Later, Mercedes tell the girls she might have more feelings for Sam she thought.

Will has Emma's parents over and asks for their blessing. They don't give it, telling him they aren't sure if Emma is ready for the messier components of marriage and parenting.

The Glee kids ask Artie about his relationship with Becky. They think it's weird. He calls them on their not being accepting of different people.

Will brings in Finn's mother (Romy Rosemont) and Burt (Mike O'Malley) to talk about him thinking of joining the army. They want to know why. It seems clear most of the reason is so he can follow in the footsteps of his father, who died in combat. At this point, his mother tells him she's been lying to him. Finn's father didn't handle combat well and was dishonorably discharged. He had issues with drugs and eventually OD'd back at home. Finn is furious.

Becky sends Artie a suggestive picture of herself and mentions something physical happening that night. Artie goes to Sue and says Becky got the wrong idea. He isn't sure what to do. She tells him he should treat Becky like any girl and tell her the truth.

Will presents some of the concerns Emma's parents had to her and asks whether her disease will allow her to handle what comes with the territory of marriage, babies, etc. She gets emotional and says she loves him and all she can promise is that she'll try. She says he needs to figure out if that is enough and leaves.

Rachel, Kurt and Finn talk about their future. Rachel and Kurt are worried about getting into NYADA. Finn wants to have something special in his life. Rachel breaks into "Without You."

Sam stops Will in the hall and tells him he has an idea for how to propose to Emma.

Will walks Emma down the hall where students and faculty members including Beiste & Sue hand her roses. They go to the pool. The Glee kids perform a synchronized swimming version of "We Found Love." Afterwards, Will asks her to marry him. She says yes.

Artie tells Becky she may have gotten the wrong idea. She asks if it's because "I'm too intimidating." He says yes. She walks away and her thoughts tell us she didn't ask whether the real reason was because of her Down syndrome because she thinks that was the real reason. She tries not to cry but breaks down when she reaches Sue's office. Sue says she too was recently dumped (by Cooter) and they will get through this together.

Finn asks Rachel to meet him in the auditorium. He tells her the something special he needs in his life is her. Finn then takes out a ring and asks Rachel to marry him. Rachel looks down at the ring.The episode ends.
