Continuity mistake: When Michael is finishing up the Allen key, he is wearing his grey sweatshirt. Yet when he finishes it and checks it on his tattoo he is wearing his blue shirt over his sweatshirt. (00:36:00)
Continuity mistake: After the gas canisters are thrown into the rabble, Michael runs back up into his cell and puts his hands on the bunk, they are clean. The shot cuts to T-bag yelling up at him and when the shot goes back to Michael, his hands are covered in blood. (00:32:30)
Suggested correction: When Michael stumbles into his cell and leans against the wall, there are blood trails over his hands. He then stumbles against the bed, and his hands are out of shot but his wrists are still visible. Then, when he falls back against the wall, his hands are visible with the blood trails.
