Here’s an idea for a potential tweak.
It seems like the official canon has retconned a line from TLJ that implied something they wanted to nix. This proposed alteration brings TLJ in line with the canon story about what happened, and removes the red herring. It is the scene in which Luke first tells Rey about the night of the Jedi Temple massacre.
Original line: “When I came to, the temple was burning. He’d vanished with a handful of my students… and slaughtered the rest.”
New line: “When I came to, the temple was burning. He’d vanished… and slaughtered my students.”
Here’s the clip, though in audio only. I didn’t want to re-rip the video stream just to test out this idea:
