Charlie's playing air piano (or, actually, table piano) when Chuck comes in. Charlie says he's not okay at all, since he doesn't know where he is and someone is trying to kill him. But he adds: "On the plus side, your friend's tranqs are out of this world." Casey, watching it on a monitor, growls. Charlie's never been in a situation like this, since he's lived his life avoiding anything real. Charlie asks Chuck what he wants him to do, and Chuck asks him to perform tonight. Charlie thinks it's madness, but Chuck gives him a much better pep talk than the professionals just gave him. He tells him he'd give anything for one night of bravery in exchange for a lifetime of normalcy. Chuck says Charlie can trust them because he does, and he stakes his life on it every day. It's sort of cheesy, but we quickly move on to Charlie accepting by saying, "Hello, Cleveland." When Chuck tells him it's Burbank, Charlie says, "I'm dyslexic."
At the Buy More, the Bus thanks Morgan, Jeff, and Lester for giving him the golden ticket, acting like it means so much to him, then he sells it to one of the background Buy More employees, for $800. The guys are annoyed and disappointed, but get back to work.
The concert's about to start. Chuck's in the dressing room with Charlie, when Casey tells him they've spotted Achmed. But it's a guy who Achmed paid to wear the outfit. They see a bunch of others, too. Achmed's not even in the outfit and, besides, he's already backstage and killing guards. He knocks on the door, and Chuck goes to the door. He sees it's Achmed, and tells Charlie. Charlie can't believe this, since Chuck told him they were safe. He drinks. Chuck tells him to hide in the closet, and that he'll deal with Achmed. To Charlie's credit, he does worry about leaving Chuck out there. I love that they developed this cute little friendship over the course of one episode. Chuck tells Charlie to take off his shirt before he gets in the closet. Achmed starts trying to knock the door in. Chuck tells Sarah what's up over the watchsponder, and then starts to tell her what's been bothering him when Achmed knocks him down with the door. Chuck pretends he doesn't know where Charlie is, but Achmed quickly realizes he must be in the closet. Chuck admits that it was a horrible plan, but then Chuck says he knows about the tattoo and what it means, and shows him an email with a picture of it on his iPhone. If Achmed takes another step, he'll send it, proving the cell is mightier than the sword, "or very large knife, in this case."
