I don’t think it’s unreasonable to think he learned at some point in between the trilogies. :p I will admit that’s the one thing I can’t quite figure out with this idea.

Well I haven’t exactly planned out all the motivations and everything with Anakin. It was just an idea I’ve been sitting on for a while for how to solve the problem of preserving the reveals while not letting the audience feel like they’re missing information. It would have to be something of Anakin becoming weary of his own identity and finding solace and power in taking up the identity of somebody else. Maybe it all comes down to simply the Emperer’s manipulation of him.

Well the idea of official apprenticeships is certainly not a make or break thing for this to work well. Maybe Darth’s motivation for joining the dark side isn’t disappointment in the Jedi order itself, but a more personal disappointment specifically in Obi-Wan as a teacher. A line could be thrown in about how “I expected so much more from the protege of the great Yoda, but you’re just so weak.”
