Revealing mistake: Michael climbs out of the hole during the escape in his coveralls. When he looks down to shout to the others to say it's clear he has no top on. The shot is reused from when he first climbed up. (00:37:10)
Other mistake: When Michael climbs up the rope to get to the room below the infirmary, the rope is hanging from the manhole cover, but he still manages to lift the cover whilst hanging from it. In the next shot where he looks down the manhole, it's clear that there is nothing other than the rope he could have held on to while lifting the cover. An impressive accomplishment, defying the laws of gravity. (00:38:00)
Continuity mistake: 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".

Plot hole: In a previous episode Link says he ditched the gun after he was framed and that he chose the gun the night before. Earlier in the episode, Michael met Link off the street, then went to a bar and met Veronica, then those two go to Michael's apartment. At the apartment, Michael gets the call from Link who is trying to get Michael to talk him out of killing Stedman. But how could he choose a gun the night before when he is asked to kill Stedman and calls Michael on the same day?
Continuity mistake: "Episode 16-17. In Episode 16 when Linc is to be executed you see the clouds pass in front of the full moon. In Episode 17 - a couple of days later - you again see the full moon."
Audio problem: When C-Note and the other guy are talking at the train station the other guy says "-been on lead for a long damn time now" and his lips aren't in sync with the sound.
Continuity mistake: Before being sent to psyche ward, Michael had brutally hurt his right hand by repeatedly punching it at the cement wall of the cell. But moments later,seen in psyche ward after being cleaned up, there's no sign of any hurt on that hand, even no gauze covering at all. We can see his normal good hand.
