oh... no offense, but that ending kinda sucked. It was very abbrupt and how the fuck did gee die?
Aw, sorry you didn't like it. :/ Yeah I know the ending was a bit abrupt, which is part of why I put in the extra chapter to cushion the blow.
But to answer your question: During the part where Bandit looks over at Lindsey while talking to Frank, she mentions he died of end stage lung cancer. Probably from his smoking habit.
