Continuity: This happens in the scene where Lisa is scolding LJ for getting arrested. When LJ says "I don't have a father", he is leaning on the table with his arms crossed. When the shot changes, his arms are uncrossed and in a completely different position.

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.

Continuity: Episode "Cute Poison": When Veronica is having coffee with Nick, she picks up her cup to take a sip and is holding it around the rim. When the shot changes she is holding it by the handle.

Revealing: Near the end, when Michael is unscrewing the sink before kicking the wall in, watch his hands in the foreground while he is talking to Sucre. Just when Sucre says "But what you were doing up there in the infirmary." Michael starts using his fingers to take the bolt out. You can see that there is no bolt, just him turning air, with a mystery 'unscrewing' sound effect.

Factual error: During the last several minutes when the Governor and warden are discussing the current situation and the status of the governor's daughter, a cut away shot is shown stating that it is the Capitol Building Springfield, Illinois. The Capitol building shown is in fact the Capitol of Connecticut, in Hartford CT.

Visible crew/equipment: In Riots, Drills and the Devil Part 2, when LJ's mom turns off the TV, the camera man's image can be seen in the glass next to the television.

Continuity: This happens during LJ's fight with his mom and step-dad. When LJ says "You got no clue do you?" you can see Lisa's hands on his shoulders trying to calm him down. When the shot changes, Lisa's hands are on her hips.

Continuity: In the scene where LJ comes to visit Lincoln and admits to breaking the coffee table, LJ's hand moves between shots. When Lincoln is shown, you can see LJ sitting in front of him with his chin resting on his hand. When the shot changes to close-ups of LJ, his hand is down and completely out of the shot.

Continuity: S1E09 - When Abruzzi's lawyer tells Abruzzi he is broke, Abruzzi points at him saying "I told you form the beginning what would happen if he screwed me.". When it cuts Abruzzi's hand is suddenly lowered.

Continuity: In the episode "The Old Head" when Michael gives the cat back to Westmoreland, from the side, the cats paw is on his shoulder but when the angle changes to the front, it has moved down to his chest.

Plot hole: S1E11 - When Scofield comes back after visiting his wife, Fernando announces his arrival. However the problem is, everyone is inside digging the hole. As Fernando walks in along with Scofield, it leaves no one outside watching for guards. The guys are at least smart enough to keep the watch outside instead of all staying inside. If a guard shows up unnoticed, they are screwed.

Continuity: In Episode 14, "The Rat", when Lincoln and Dr. Tancredi are in his cell together, he says "How it gonna feel when they tighten the belts". He then turns his head so that he is looking the doctor in the eyes, but when the angle changes, he is staring directly in front of himself, and his head is not turned at all.

Continuity: When Scofield tries to make the guy remember the path, he touches his chin with both of his hands, and there are no tattoos on his left arm.

Revealing: When Pope bursts into the infirmary and sees Westmoreland's body, watch the collar of Westmoreland's jacket. You can see it moving up and down as though he's breathing.

Revealing: After Pope enters Schofield's cell to see the escape hole, we see him standing outside the cell looking out at everyone throwing toilet tissue etc. If you watch closely right after we see a guy pulling his pillows toward him to tear up, it cuts to another inmate who is throwing stuff out as well. Only thing is, we see the cell door slide to the side slightly which would indicate that the cell doors where not locked. In the event of an escape, lockdown would happen immediately, with all cell doors locked with the prisoners inside their cells.
