Commercials. Sorry, Applebees, but "wonton tacos" don't sound appealing, even if you pay John Corbett to talk about them.
When we're back, Casey's duct-taped to a chair as Chuck points a gun at him. Pauly and Edgar want him to stop stalling, but Sarah tells him to keep stalling. Chuck puts his gun down and says he's not a murderer; he's an assassin. He kills as a means to something, and in this case, it's to get information, which he wouldn't get from a dead guy. He asks Casey who the leak is, and Casey says he's not telling him. Then, through his teeth, "Sell it." Pauly offers Chuck some torture tools, and Chuck grabs pliers and heads toward Casey. They communicate with their eyes, Casey telling Chuck to pull a tooth and Chuck not wanting to. Until he finally relents and does it. Just then, the feds bust in to rescue Casey. Sarah corners Chuck, who tells her he's freaking out. She tells him to stop it. He's not him; he's Rafe, and needs to think about what he'd do in this situation. So Chuck flashes and takes out all the cops with his kung-fu fighting, including Sarah. Then he, Pauly, and Edgar get the heck out of there. "Rafe" tells them to split up and he'll contact them later. Edgar says he's incredible. Inside, Casey's impressed by Chuck and Sarah looks mopey again (although very pretty with her hair up -- apparently she put it up before going in to save them in an emergency situation -- and black eyeliner).
Castle. Chuck shows up and says he has a lot to do, but Casey says Shaw and Sarah went to his place to fix dinner since they knew he wouldn't have time. Chuck's surprised, and Casey says, "Weird huh? Walker helping you get laid." Chuck apologizes about Casey's tooth, and Casey says he got the one with a cavity, saving him a trip to the dentist. He tells Chuck he's proud of him, and even though he's a little disgusted with himself for saying that, it's very cute. Some government guys lead Rafe through the room to interrogation, but he freaks out a little and they knock him down onto the table next to a Buy More pen. After he's out, Chuck asks about the name Alex Coburn, and Casey tells him to mind his own damn business.
