Mars Investigations. We see Keith sitting at his desk, and then someone comes into frame, but all we see at first is a paper bag and a shapely ass. Keith looks thrilled as he speculates that the bag contains a ham-and-cheese sandwich, and Alicia is gratified that she didn't go with chicken salad. Keith tells her that a beautiful woman bringing a guy a sandwich is one of the top ten male fantasies. Hmm. I suppose that means having the sandwich delivered by beautiful twins is somewhere in the top three. Keith has the good sense to make out a little with Alicia before diving into the sandwich, but Alicia asks him mid-bite if he has a spare gun she can borrow. Honey, if you're going to make him choke, at least have some water at the ready. Keith evenly asks who she intends to shoot, and Alicia confesses that Chicago Dude is an old boyfriend of hers. Keith starts to point out that she was less than forthcoming when it happened, but Alicia says she was totally thrown (I'd point out that given her reaction when they were first talking about Chicago, that might not be completely true), and that she was with the guy almost twenty years prior, before she was married. She was naïve and he was crazy. I'm surprised it happened in Chicago, because it certainly sounds like the beginning of a country song. Keith asks about the gun, and Alicia tells him about the drive-by. Keith says he can't give Alicia a gun, if only for safety reasons, but that he'll be happy to crawl into bed with her at night. Jeez, Keith, didn't you get enough in Chicago? Alicia asks what they'll tell the kids, and the answer is nothing. Seems a little devious, but they'll probably thank their parents for it.
