What if Lucasfilm decides to do the Ben Kenobi film, and in the film he meets up with Vader, which is how he now knows “He is more machine now, than man…twisted and evil.” How did he know what he looked like or what he was made of? Was it his presence? Did he hear rumors of Vader and assumed it was Anakin?
He has to meet him in the new film, and he has to mention to Vader that he has his lightsaber, which Vader could say, “I want my son to have it.” that could fix one continuity error. But, then there’s another error. Vader says, “When I left you, I was but a learner, now I am the master.” so I guess that wouldn’t work would it.
