Fourth character reminds me of a character my friend played. His name was Jim Spoons, and his backstory was that his wife was murdered and he was trying to find out who the murderer is and avenge her. He carries this out until the final session, when it is revealed that he in fact was the one who killed his wife, and that Jim Spoons is an anagram for… OJ Simpson
