Top Portal Secrets That You Probably Didn’t Know

The Rat man is schizophrenic

This point doesn’t surprise me, given the times that he was alone and the entire mental and emotional trauma that this man went through, he was bound to crack up. If you are wondering what possessed the Rattman to draw all the crazy murals on the wall, it is said that in  comic Portal 2: Lab Rat – which is where most of Doug Rattman’s sad story is told – he is a said be a schizophrenic  and is taken off his medication while hiding from GlaDOS. I really feel sorry for this man.
