Usually in movies,tv,games,books,etc there are events unexplained and we as an audience are left wondering.
What events do you have theories about and what is said theories
My theory is about the dark knights joker, how he got his lovely scars(in comics joker is referred to as jack)
Jack was a comedian a very poor one at that. He at one show made a joke about a local don. Said don was TICKED. He had him captured and given the grin for punishment. The pain drove him to madness he lost sight of reality and he thinks what he is doing is a game...for fun. He is crazy because of one joke...his killing joke if you will.
