Revealing mistake: In the scene where Sarah crashes into the agent's buggy, you see they have been replaced with dummies. When the car first hits, you see one of the dummies fall out, but they are both seated in the next shot. Also you see that it is not Sarah driving but a man.

Audio problem: When Gretchen kills the guy in the prison he lets out a very obvious fake scream similar to a Wilhelm scream. Also, he is being choked around the neck, how is he able to make the scream? Take note of when you see this scene in the next episode's review. The guy doesn't make the scream in that version.
Audio problem: When Mahone is speaking to Baker, just after Michael goes under the X-Ray, Baker says ' My goal is to build one city that entirely self sustains'. After this, Baker's words do not match the actor's mouth, from the shot behind him; 'Depending on no outside resources'.

Continuity mistake: At the car dealer where Don Self speaks to the seller, the seller says "How did you find me?" and they are inside the car dealership. Don responds with "I've never lost you". Suddenly when Don answers they are outside the building, like they teleported.
Plot hole: They exchange Scylla for the life of the general's daughter. If they counted on him valuing his daughter over Scylla, which he did, they wouldn't have had to steal the cards or break into the vault in the first place. Just kidnap the daughter like they did, tell the general to gather the cardholders and hand over the cards, give them Scylla and let them out.
