Vader killing Ahsoka ever. Just not down with it. It seems like a fitting end, but just too morbid for my taste. Think about it, Vader NEVER knew Luke, but he wanted to "get to know him". When Luke rejected his offer to join him, Vader didn't kill him. Ahsoka was almost like Anakin's child, they shared a closer bond than he did to his own children. To have him slay her just seems grotesque. The only way I could even fathom it is if he was more and more bitter that she left him, and in total self defense he killed her. Then he has to be even more remorseful that he did it. I want to hear breathing and tears behind that mask!! But if he killed her maliciously and in anger, it would cheapen his "redemption" in ROTS. As far as Ahsoka being part of a different series? I'm leader of that bandwagon!
