Mob didn’t transfer any emotions to me, just his powers. Even though I’m a spiritual expert, that particular evil spirit was pretty strong.. unlike those other opponents who cheated with holograms and cheap tricks, I think that was the only real deal and I’m glad Mob knew when to assist me :-)
AU: The twins are separate except Luke is given to Padme's successor to Naboo while Leia stays with Bail Organa. Leia and Luke could be more aware of each other. Luke could be a leader in the scene of politics or he could still wish to fight with the rebels and does so much to the weary of everyone else but regardless of putting a prince at risk, he's too good of a pilot for them to not allow him into the war zones. Darth Vader could sense Luke and Leia and capture them both.
