Chuck calls Sarah and Casey at Castle to tell them not to be mad, but he may or may not have called Sydney so she'd track him to the Buy More. He says it's his trap, then he sees Sydney showing up, and he tells Sarah to grab Casey and get up here to take them out. Agent Superman takes the phone and tells Chuck this wasn't smart, and if he starts things on his own he has to finish them on his own. "Good luck." He hangs up, and Casey says he won't be able to handle it on his own. Sarah says without them, he'll panic and won't be able to perform properly. Agent Superman says it happens to lots of guys. Or so he hears. Agent Superman says he's kind of curious about the plan anyway. Uh, the plan was for them to go save him; didn't he just say that. Back upstairs, Sydney and three or four big, burly guys walk in. Chuck talks to them over the intercom, requesting they go to the home theater room. He even suggests a route, but one of the guys finds him. Chuck plays dumb, and says the store's closed and they can come back in the morning. Casey and Sarah say they're going on, so Agent Superman pulls guns on them and says he's going to have to ask them to stand down. He reiterates that he doesn't like guns, but he'll use them when he has to.
Sydney tells Chuck it's a little weird to meet in an electronics store, then asks about Agent Superman. Chuck says he killed him; Devon was just a patsy. Sydney's skeptical, and calls Chuck "Mr. Buy More." She says he shouldn't have any problem with Glenn and Ian, then, and leaves Chuck to fight two of them. Chuck makes threats but can't flash, so one guy punches him out. Chuck gets up with a bloody mouth and says he's angry and in a great deal of pain. He makes ridiculous martial arts motions and sounds at them, then runs off. Back at Castle, Agent Superman scoffs, "That is the plan?" Uh, no, dude: The plan was SARAH and CASEY. Is he a slow learner? Sarah says she's going in: "Shoot me if you have to." He turns to follow her with the guns, but Casey draws his own and points it at Agent Superman before he can. He tells Casey he's fast, and Casey growls, "I love guns." Agent Superman puts his down. Go Team Bartowski!
Casey follows Sarah up to the Buy More. Casey stays on the guys out front and sends Sarah to the back after Chuck. Sydney and two of her guys are there. She asks them to check out the cage. Chuck's hiding, and lights up the battery power on the cage just before the guy touches it. It zaps him and he accidentally shoots the other guy. Thank goodness for fight club, right? Sydney takes out her gun, but Sarah shows up and kicks it out of her hand. They have a bad-ass girl fight like this show is so famous for. Sydney mostly wins and starts to run, but Chuck pulls a gun on her. She runs anyway, knowing he can't shoot. He follows her outside and tells her not to move. She turns around with her hands up, and asks, "Or what?" He asks her to please do what he says. She says spies don't say please and Devon would have had a bullet between her eyes by now. She reaches for her phone, as Chuck tells her not to do that. She says she can think of a use for it, calling fifty operatives here. Chuck says, "Don't make me shoot you," and she says she doesn't think he can. Sarah comes out, but Sydney's already been shot from behind. It's Agent Superman, who once again says he hates guns, but it pays to know how to use one. Maybe with this guy here someone will finally teach Chuck.
