He walks back into the place in the guitar player's jacket and with his guitar. Someone sees him, says he's late and ushers him on stage, ignoring his request to use the restroom. On stage, another guy in the band asks where Manny is, and Chuck says, "Spastic colon. I'm filling in for him." Nice. Chuck awkwardly kicks his guitar case shut and starts making "Mah, mah, mah" sounds into the mic. Casey tells Sarah he's going to blow the whole op, but she says to give him a second. Then Chuck flashes on the guitar and starts playing. Sarah's fake boyfriend asks if that isn't her ex, and she says, "Yeah, he's a bit of a show-off." Chuck mouths "assassin" to Casey, but when Casey asks where, Chuck just shrugs. The fake boyfriend offers to take care of Chuck, but she says no, and asks him to come dance. Chuck watches them dance, and then fake boyfriend asks how he knew Sarah was here and who is he anyway. She says he has nothing to worry about and they dance sexily as Chuck gets more and more frustrated on stage. Casey tells someone to tranq him, but he ducks and they tranq a member of his backup band instead. Outside, the guitar player Chuck knocks out wakes up and removes his moustache and wig. He heads in and points a gun at Sarah and her fake boyfriend. Chuck sees the gun's laser and jumps off the stage to save her. Everyone jumps up, and he says there's an assassin. Casey and Sarah are pissed he blew the whole thing since half this place was undercover agents. Chuck swears there was an assassin, but Sarah tells him he doesn't work anymore, and it's over. Some boots (either the fake guitar player/assassin or Sarah's fake boyfriend, who disappeared in the melee) find Chuck's pocket protector nametag outside. Uh-oh.
