Chuck gives Ellie the antidote and then sits in the hallway and kvetches with Sarah and Casey about how he is going to die. On the plus side, he doesn't have to come up with another five-year plan. Just as he is about to settle in for a good long sulk, he spies the spy's (ha!) tracking device on the ground. When he picks it up, he flashes on Mr. Stripey. Mr. Stripey is an ex-gymnast who blew out his knee and now sells atomic secrets on the black market. Is that what Kerri Strug is doing these days? Geez, life after the Wheaties box is tough! To the hot beats of Britney Spears (really!), Chuck, Sarah, and Casey track down Mr. Stripey to his lair. As Chuck tells Sarah that she's pretty and tells Casey that his jaw was chiseled by Michelangelo, they knock on Mr. Stripey's door. Mr. Stripey asks who is there, and Chuck announces it's the NSA, CIA, and him. Then they bust the door down and point their guns at Mr. Stripey until he tells them where the antidote is. Just as they are about to swallow it, Chuck stops them. He's read enough comic books to know that the villain should sample the antidote first. You would think that point would be stressed in either the CIA or NSA employee manual, right? In Stan Lee veritas. When called on his bluff, Mr. Stripey literally cartwheel-back handspring-back flip-round-offs right out of there and is about to escape (again!) when Sarah shoots him in the knee. Casey applauds her unsportsmanlike conduct. They tie up Mr. Stripey, who tells them where to find the antidote, key, and codes. Before they take the antidote, Chuck asks Sarah the truth. The truth about whether they have a future aside from their cover story. She says no and gulps down her antidote faster than a Jager shot during pledge week. Chuck looks chagrined and takes the antidote.
