Other: When T-bag catches Michael in his cell looking for the Allen key, he says, 'What are you doing in my cell?' but he doesn't have his usual southern accent.

Continuity: 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.

Continuity: When Michael is feeling the screws in the benches looking for the right one and finds it, you see him touching it and the head of the screw is old and dirty and fixed into the wood. When he gets on the bench to discreetly unscrew it, it is now clean and sticking out a little way, obviously so the actor can twist it out more easily.

Continuity: 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.
