So Elliot and Olivia ride back over to Rook's place and listen in as Cragen dials the lodge number again -- answered by Rook in his apartment, and the detectives swoop in. They note several rental phones. Rook, still on the phone: "Please hold."
Back at the station, Rook wants the detectives to believe that he'd rather his co-workers think he was just playing hooky rather than he was with a prostitute, which is what he's saying now. Here's a tip for the detectives: when you check his alibi with the hooker? Don't do it over the phone. He says he misses his dead wife terribly. Oh, so it's like Good Will Hunting! Elliot has a different take: "You screw whores in your dead wife's bed." Rook says they just sleep, which he finds comforting, and if he closes his eyes, it's like Juliet's back. Then, at the mention of Happiburger, Rook says he hasn't eaten there in twenty years, since he's a localvore, meaning he only eats local, organic seasonal food (optional: being insufferably smug about it).
Casey and Cragen are watching the questioning. Casey says they don't have him for anything other than obstruction for lying, and they need to prove he made those calls. That's Fin's cue: he strolls up with surveillance photos from a bank camera that happened to pick up Rook entering the library just before the call was made to Happiburger. "Lock him up," says Casey.
Rook's representing himself in court, and judges on Law & Order are contractually obligated to remind such defendants of the adage about the man representing himself has a fool for a client. Rook says he doesn't make enough to afford a private attorney but too much for a public defender. Isn't there something in Miranda about "if you can't afford an attorney, one will be appointed for you"? The judge says just that, and Rook shits all over court-appointed lawyers who will sleepwalk through the trial of a client who won't make him rich. He amiably agrees to $250,000 bail (he'll put up his apartment for it), and then tells Casey he's looking forward to working with her. He's smiling like he knows how often she loses cases. "Yeah, should be fun," she says.
During the trial, Rook asks Elliot (who says he has no doubts about Rook's guilt) if he's ever heard of someone strip-searching someone else on phoned-in orders, Elliot says "nothing surprises me" about what depraved people will do, and doesn't say anything about the RASH of cases the police know about. Rook asks if it doesn't make more sense that Lomax wanted to get his jollies and then concocted a cover story. And it kind of does make more sense -- except for all the other cases the cops know about. Which Elliot again doesn't mention. He says a phone call was made from the library to Happiburger that morning on a phone card Rook bought. Rook reminds him that he gives them to homeless people, who are known to hang out at the library, and also be crazy! Elliot says they have a photo of Rook entering the library. "Are you sure?" asks Rook.
