My Theory on Sofia's Life... *episode 4 spoilers*

My first clue to the theory I have comes from the inmate waking around without chains in the cafeteria... it's too surreal and makes no sense, even for Arkham. Further, no one really reacted to her. I saw the woman immediately as a Tyler Durden... aka, it's all in Sofia's head. She actually beat someone to death that day, like she did to Magpie later. I think Dr. Rush is also in her head, I mean what doctor is just standing in the cafeteria apologizing like that? I think Carmine used his money to hide Sofia's illness because he, like her mother, is a proud person... but it got too bad. I also think Oz watched Sofia murder the reporter and told Carmine, which led to him having to finally put an end to Sofia's insanity and admit she needed help. I highly recommend rewatching the episode with a "watching Fight Club for the second time" mentality.
