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.
Answer: Because of coincidence.
