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. (00:36:50)Melissa Jane Swift
Other mistake: Michael goes to Fox River in April. Maricruz gets pregnant in the same month. In mid-June, when Michael get arrested in Panama, she's still pregnant. That's 2 months. He was in there for about 2 weeks, due to his deal with the company. Therefore, he would have escaped Sona at the end of June or the start of July. The start of Season 4 is set 3 weeks after the escape from Sona, so Maricruz should be 3 months pregnant, but gives birth at the start of season 4, meaning that the baby is 6 months early but looks very healthy.
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.manthabeat
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'. (00:19:45)Callum Lloyd Edwards
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. (00:13:25)
