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'. (00:19:45)
