Why are people talking about saber colors and Force lightning in a thread about retcons? If you're going to talk about continuity, don't leave out the fact that the writers completely ignored previously established canon regarding Garm Bel Iblis, Bail Organa, and Mon Mothma. It was also rather sloppy of them to try to convince us that the Rebel Alliance had only three major leaders.
