Charlie is Charlie Gordon.The following will spoil the ending of Flowers for Algernon. Think about it. At the end of Flowers for Algernon, Charlie moved out of New York. Since this was an attempt to move somewhere where people didn't know him, he may have changed his last name to Kelly. He then got a job at Paddy's Pub (also cleaning), and he kills rats because they remind him of what he can remember of Algernon. He didn't remember his parents, so he probably met up with his "mother", who thinks Charlie is her real son because she's, well, crazy. Since Charlie's memory was decreasing, everything said about his past in the show was probably just made up by him, and everybody in the show plays along out of pity. The most clear evidence of this theory are Charlie's impossibly bad spelling, not to mention the fact that he's already borderline retarded.
The finale will be exceedingly dark and humorless and will be about the group realizing that Dennis is a serial killer
Green Man is Charlie's "safe" persona created to cope with being molested
Dennis is a reincarnation of Patrick Bateman.
The finale will have the whole gang die.
The Waitress' name is Nicki Potnick.
Mac isn't really gay. He's just confused and the writers are just messing with us
The gang will eventually kill Cricket
