One of our many Rebel spies sent us this rumor regarding the possible background of Adam Driver's character in Episode VII.
Sounds like Adam Driver is NOT going to play a villain...sort of.
He will be playing the son of Han and Leia, and it seems he will be seduced to the Dark Side, and a main plot point for the movie will be their attempt to rescue him.
We cannot stress enough, this is a rumor, NOT a spoiler. Until Lucasfilm confirm it, please treat it as such.
