He’s said before that the Leia scene doesn’t bother him so I think he is going to stick with that. I’m with him on that decision.
I don’t think he’s going to change the title but he’s had a theme of using book titles for his edits so I think he would stick with that. I think Dark Force Rising would fit well with TLJ too, but I don’t think it necessarily needs a new title. Legacy of the blank would make for a cool title though!
