Why is Artie dismayed? Because Becky has been in the audience watching the performance, and now she's walking up to him on the stage. She tells him it was awesome, and a "great Part One." Artie wonders what she means by "Part One," since he thought that was the entire date (which he must have said yes to during a commercial break). But Becky's no fool. She knows what a date is, and on this show, it's always dinner at Breadstix. So that's where she's going to go with Artie.
Hey, it's the jewelry store set in which Santana sang "Santa Baby," in a scene that was unfortunately cut from the last episode and every trace of which has been deleted from the web. This time, Will and Finn are there while Will shops for an engagement ring. There's some blather about how Finn is generally not smart and how Will doesn't want to fail at marriage like he did last time. And then Will asks Finn to be his best man. He has really got to get some grown-up friends. Especially when he tells Finn "You've taught me more about being a man than anyone I've ever known." That is so sad. Finn accepts. And then he tells Will that he's thinking of joining the army. Because he wants to do something special, "like my dad, but without the whole dying part." Commercials.
Will's office. Rachel, Mercedes, Santana and Tina are there to get some info so they can plan the right proposal. Will points out that he has proposed before. Santana: "Oh yeah, how did that marriage work out for you. I mean, what was your big move then, a jumbotron that said 'Hey Terri, I want to make a fake baby with you'?" Mercedes interrupts the heckling to ask about the first they met. Cut sideways to Will walking past Emma as she puts her nameplate on her door. He welcomes her to the school, and then they give each other a look as he walks away. Back in his office, Will tells the girls, "I'll never forget how I felt the first time I saw her." That gives Rachel the perfect idea.
Auditorium. The four girls from the previous scene are on stage, each in a little black dress, sitting on a stool. And they sing "The First Time Ever I Saw Your Face." Each of them sings in turn, and as she sings, you get images of her thinking of her beloved. Rachel thinks of Finn, Tina thinks of Mike Chang, Santana thinks of Brittany, and Mercedes thinks of Sam. Because, duh, Sam's a total hottie and Shane's a total tool. As they finish, Will claps, and Mercedes, in tears, walks off the stage and into the bathroom.
