Abruzzi hustles T-Bag out of Michael's cell, snarling, "Listen up, pervert! You're in as much trouble as he is -- do you understand?" T-Bag hisses, "If you were to stick me, I'm sure I could scream awhile about the escape passage before becoming one of the Fabulously Gay White Supremacists In the Sky."
Dr. Tancredi proves she's no fainting violet: not only does she find a good position from which to attack, she's just fashioned a shiv. As she waits, she puts on her angry face. Go, Sara!
In cellblock A, the inmates who are watching on the monitor shout in joy. One yells, "Yo! Stroke's about to get the doc!" Michael looks seriously alarmed. He runs in to check out the monitor and sees Sara crouched behind an examining table, shiv at the ready. He strides back into the cell and tells Sucre to finish what they started, as he's off to sick bay. The guard's all, "You can't get into B-wing." Bobby was previously under the impression that he and Linc were in no danger of getting caught by rioting inmates, so I'd discount anything he says for now. Michael's all, "No one touches the CO No! One!" And he disappears. Abruzzi watches him go; his frustrated expression only deepens as T-Bag leans in and snarls, "You gonna clue me in, paisan?" Yeah, I get the impression T-Bag's no fun on a road trip. Always asking people to hold his pocket is probably embarrassing at rest stops.
Turk is leading Lincoln into a conveniently secluded part of the prison, telling him, "It's faster if we cut through here." Lincoln is either too dazed from pain or too stupid from whatever to question this. As they lope around, we see that Turk is wearing a leather string tied around his wrist. And just in case we don't remember back 50 minutes, we also get a flashback to him on the phone, assuring Diamond, "Burrows is as good as dead."
And then we see Michael scamper through the prison and pop out on the roof: he runs over to the edge of the roof to confirm that yes, Dr. Tancredi's trapped in sick bay with no way out. The last shot of the episode takes us back inside, where she's resumed her crouch by the examination table, breathing heavily from fear and/or adrenaline, shiv out. Stroke is but a few strikes away from breaking in the window.
Will she make it out? Will Lincoln be killed, thus guaranteeing that Michael's gone to all this trouble for nothing? Will T-Bag be tossed from the escape plan? Will Veronica find something in D.C.? (Do we care?) It's all to be continued.
