Weight room. Finn is alone and struggling to press a weight that is about to crush his larynx when Sam rushes in and saves him. They have a talk about body image, in which Sam complains that he felt fat in those little shorts, up on that stage. If Sam feels fat, you know that's a serious body image problem. Sam thinks he was replaced as Rocky because he complained about the costume, which makes Finn worried that he'll also be replaced. Sam tells him not to worry, since the role of Brad isn't about looking hot, it's about feeling confident, "no matter how douchey you are." Sam tells Finn that if he's just himself, "the sexiness will flow through." I really hope that's a scene that got edited out of the McKinley version of Rocky Horror. Sam has given Finn a lot to think about: "Yeah, you're right. I don't need to hide behind my muscles like you do." Sam: "Awesome. I think. Are you insulting me?" He'll have to figure that out on his own, because Finn is leaving "to show everyone how hot and sexy I am." We get one last gratuitous shot of Sam checking out his own abs in the mirror.
In the auditorium, they're rehearsing the scene in which everyone has discovered that they had sex with everyone else, which consists of the characters of Janet, Brad, Frank, Dr. Scott, and Rocky just saying other characters' names in an accusatory and/or guilty tone of voice (except for Rocky, who just growls). Finn's not there, so Will is running back and forth playing both Rocky and Brad. All of this while Sue sits in the criminologist's armchair and talks about how preposterous the play is. She appears to be in costume, by the way -- a slightly looser black and gold tracksuit with an ascot. Rachel complains that it's pointless to rehearse without Finn, but Will notes that Finn's late and isn't answering his cell phone. He also asks Sue to please stop interjecting her opinions during rehearsal. Sue: "Opinions? These are my rewrites." Then Maharishi Figgins enters the auditorium and calls out to Will.
Maharishi's Pagoda of Punishment. Finn's there, and Figgins has just told Will that Finn is suspended. Why, you (and Will) ask? Because he decided to show everyone how sexy and confident he was by walking down the hallway in his boxer shorts. Flash sideways, where we see that he was also wearing sneakers and his Brad glasses. The kids aren't acting like they think he's sexy. More like he's an object of fear and/or ridicule. The topper comes from Azimio and Karofsky, who joke about the old man nature of his underwear. Back in the Maharishi's office, Figgins says that he's leaning towards a one-month suspension. Will asks for Finn to leave so he can speak with Figgins alone. After Finn leaves, Will tells Figgins that it's no crime to come to rehearsal in costume. Figgins: "Nine children have already signed up for after school therapy. I had to bring in a grief counselor." Will whips out some precedent, reminding Figgins that when Santana pantsed Brit-Brit after the Cheerios won Nationals, Brit wasn't suspended even though she was wearing a lot less than underwear. Figgins backs the punishment down to a warning. And then he tells Will that if there's any blowback from the show, Figgins won't be able to protect him. Which means Glee Club is at risk: "And I want to be sure that whatever you're doing it for, it's worth it."
