Casey's testing the powder to see if it's poisonous as Chuck asks nonstop questions without waiting for an answer: about the substance that sprayed on them and about Jill picking that moment to come in, and whether he's going to die. He stops after that last one, as Casey's computer thing tells him the substance is "edible." So he sticks his finger in it, tastes it, and tells Chuck he won't die, but he could add ice and sell it to kids on street corners. Chuck's like, "I knew it! Drugs?" But it's actually fruit punch. I would say something about how ridiculous this is, but Chuck beats me to the punch (pun intended) by asking if this means that not only did they get the Fulcrum list, but Jill's never going to speak to him again because she caught him rinsing off fruit punch with another woman. Casey dryly tells him it's a common spy problem. I love Casey. Have I mentioned that?
Buster's now questioning Lester at the Buy More. He's trying not to crack, saying he's not friends with Chuck, but he has nothing to tell him. He tells Buster to ask Jeff. Jeff says he doesn't rat because his mom taught him that from prison. Then they're being questioned together, and Buster tells them they can't have poker night in the backroom if they don't give him something. They tell him that Chuck's cheating on Sarah with a hot brunette. They don't know anything else about her, so Buster threatens the poker game again. Lester tells Buster that Chuck tells Morgan everything, so that's the nut he needs to crack.
Chuck's at work, leaving pathetic voicemails for Jill. Because we know he never actually works. Jeff and Lester come out and tell Morgan to give Buster something so they can keep their weekly poker game. Buster walks up as Lester and Jeff leave and asks Morgan if he's ready to help. Morgan says he will. He says Chuck's providing service on service calls, and that he has 23 years of best friendship telling him Chuck's the straightest shooter he knows. Buster sees Chuck with Jill, and points it out to Morgan. He instantly recognizes Jill, of course, and loudly says she's Chuck's old college girlfriend. He doesn't like that Chuck didn't tell him about this. Buster says they can keep their poker game and he won't tell Chuck that Morgan was the weak link.
