Morgan has his staff lined up, wondering who broke the prank truce with Large Mart, since Large Mart is claiming that kidnapping BM the BM from the BM was retaliation. He asks Jeffster! what they did, and they lead him to a closet, where a miniature pig is locked up. It's the Large Mart mascot, Kevin Bacon. Lester says they had to so Large Mart wouldn't dominate them like always. "Because, weirdly, an adorable little pig attracts more customers than a large man wearing a big, yellow-and-green BM. Call me crazy." The whole staff oohs and awws, and Jeff says he's buying whatever that pig's selling.
Castle. Jody, Robin Givens, Damian and Lewis have to turn over all their weapons, since the killer is clearly among them. Chuck's panicked! This is like D&D all over again! But Sarah talks him through it. The non-regulars briefly wonder why Sarah and Casey aren't suspects, but Chuck puts that to rest: He knows that neither Casey nor Sarah would ever kill anyone... who didn't deserve it. Chuck says the killer has to be among the other four, and they all look at Damian. He's totally offended they'd blame the bearded guy, since "This is just what my face looks like." He is totally out of here, but not before telling them he's Greek. Chuck follows him out, and as Damian opens the door to leave Castle, Chuck notices it's been rigged with a bomb. He tries to warn Damian, but it's too late; it goes off.
Power is knocked out in Castle, as everyone scrambles. Chuck says communication channels and surveillance videos are down, but Casey manages to get the emergency lights up. Although, he does add that they're locked in and alone. Chuck panics some more, so Sarah talks him through it again. He needs to trick everyone into believing he has it under control, because that's what a leader does. Chuck tries to pass being in charge off to Casey or Sarah, but Sarah pep-talks him: "You did disarm a nuclear bomb using fruit juice." Hee. Chuck tells everyone not to worry; he has this under control. Some more pieces of Castle fall on an already injured Damian. No one's really calm, and Lewis is riling up Casey, who doesn't trust an American with a British accent. Lewis says it's not his fault; it's from his semester abroad. Jody's like, "Wait, one semester? You got an accent from four months in England?" Damian agrees that's totally annoying.
Upstairs, Morgan is at his desk with the entire Buy More crew behind him, talking to a Large Mart guy and his gang behind him, discussing how to make this work out. It's very mafia. The Large Mart guys just want Kevin Bacon, and peace will be restored. Morgan wants his proof of life first, so they allow Morgan to call Big Mike. He tells BM he can't go all day without his number 2. Mike is happily eating a Subway flat-bread breakfast sandwich, which reminds him of Morgan's mama: "Muy caliente!" Morgan's heard enough and gives the phone back. Then Morgan leads the gang to the closet where Kevin Bacon was when last we saw him. But now he's gone. Morgan promises he'll get to the bottom of this if they give him until midnight. The Large Mart leader promises Morgan a big, flaming BM on his doorstep if it doesn't happen by then.
