To the Infirmary! Michael figures if Dr. Tancredi is going to keep him waiting this long, he's just going to pour toxic chemicals down a giant grate on the floor. Yes, he empties the contents of his tubes of toothpaste down the drain, and, just as we saw in the flashback, the intended "bathtub Guinness" effect is achieved. There's bubbling and fizzing, and I'm going to assume this is eating through some pipes or the floor or whatnot. After he's done, Tancredi enters, dispensing with any flirty banter. Noting the self-inflicted cut on his left eyebrow, she asks what happened. "Caught an elbow playing basketball," he smirks. The good doctor is not amused. As she inspects the cut, she lays it out for Michael: "You know you're gonna get killed in here, right? If you're not careful?" Michael answers this sobering warning with more smugness. He offers a bet, that "when" he gets out of Fox River, alive, he'll take her to dinner. At her silence, he bargains down to lunch, then a cup of coffee. Tancredi's not taking his shit today. "Michael, this charm act could be exactly what's getting you into trouble out in the yard." Sufficiently chastised, Michael leans forward for his eye bandage as the Guinness foam fizzes from the grate in the background. Nice stuff from Sarah Wayne Callies in this scene, I thought.

In the prison meeting room, Veronica and Nick are going over the events of the murder with Lincoln. They get past how he fled the parking garage and dumped his gun down a storm drain. After that, Linc explains how he went back to his apartment, saw the bloody pants in his bathtub and zzzzzzzzz...sorry, that was Linc, not me. I think Dominic Purcell actually fell asleep in the middle of a line reading. Okay, not really, but he's that low-key. He gets to the cops busting in on him, but explains that his hands were wet from splashing water on his face. You'd think the difference between hands wet with water and hands wet with water and blood would have been noticeable by the cops. You'd be wrong. Nick brings up the gun, which "had [Linc's] prints all over" it. They lose me a bit here by talking about the gun Linc dumped and the murder weapon, which I'm assuming are two different things, because the former was dumped and (according to Veronica) never found again, while the latter was apparently found at matched to the slug that killed Steadman. But, whatever, there are bigger plot holes to fill. Linc insisted the murder weapon was planted, and when Nick reminds him his prints were all over it, Linc has a revelation. He brings up "Bo," the guy who "arranged everything." This looks like news to both Nick and Veronica. In flashback, we see Linc comparison shopping for some guns in a back alley with the seedy Bo looking over his shoulder. "That was the setup right there," Linc concludes, "one of those must have been the murder weapon." Nick wants to clarify that Bo set this whole thing up so Lincoln could clear a $90,000 debt. Wha...but...wasn't the debt owed to Crab? Never mind. Don't need to know. La la la. Rather than quibble over that discrepancy, Linc drops this bomb on his new lawyers: "He was going to kill my son." Thus the ostensible lowlife morphs into a noble lowlife. Travel safely, moral ambiguity!
