He gets back in the van, and when Sarah asks what happened, Chuck says it was great, fine, they really connected. Casey's like, "She's talking about the bug, moron." He says he planted it, but he might have turned it off. Luckily, it's idiot-proof, and Casey taps in to her cell and room phones. Sarah asks Chuck why he's smiling like that and he says Jill kissed him. I know he and Sarah are over, but you'd think he would still feel a little weird just telling her stuff like that knowing her feelings for him. Or maybe he doesn't actually know her feelings for him? Could he be that stupid? Chuck looks at the surveillance footage of a guy getting into an elevator and flashes on someone's tattoo. He tells them that guy is an assassin called "Wolf Den." They see him push the button for Guy's floor and head out, telling Chuck to stay in the van. Casey adds not to touch anything.
The assassin shows up at Guy's room pretending to be room service. He comes in and locks the regular lock and the chain. Don't most hotel rooms have dead bolts or those metal bar contraption things, not chains? Back in the van, Chuck puts on the headset and listens to Jill making a phone call. I was so afraid she would turn out to be evil right here, but she's just calling her old bitch friend Sherry to tell her Chuck came to apologize. Sherry, still a bitch, says she hopes Jill didn't let that loser in. Chuck's sneering in the van. Jill says Chuck's a puppy dog and she couldn't say no, plus she thinks he's cute. Sherry says, "Cute? He's a computer dork who makes ten dollars an hour." Chuck says to himself, "Hello? It's $12.50." Only it's not just to himself, because apparently they can hear him, and Jill's like, "Chuck?" He pretends he tried to call her and must have gotten patched in. She asks if he bugged her phone, and he's like, "What am I? An entomologist?" She says she's calling security, and he realizes he's totally blown it.
In Guy's room, the assassin approaches him from behind and... tries to choke him. Wow, what a good assassin, going for the always messy and difficult choke hold instead of stabbing or shooting while you have a good shot from behind. That's just dumb. They fight around the room, and then the assassin throws Guy out the window. Oh, right, that's another no-fuss, no-muss way: a struggle followed by shattered glass and a broken whatever the body lands on. Which happens to be the van Chuck's sitting in. Sarah and Casey break in right then, and the room's empty (where'd the assassin go?). They tell Chuck Guy's not in his room right as Guy's bloody body slides down the windshield. Chuck says he knows.
