And right now the Emperor being a clone is just speculation. He could be an animated corpse, he could’ve used what he learned from Plagueis to create a new body, etc.
I’m going in with an open mind Thursday, as long as they execute and have a good story I’m cool. I just don’t want to feel conflicted about what I just watched like I did walking out of Last Jedi. The Force Awakens has me grinning like an idiot at least on first viewing. The trailers have me pumped up at least!
Edit: also that wasn’t a clone of Luke on dagobah, that was a vision of the future. I get your point, though.
