How would I re-edit TRoS? Well, for starters, I’d throw out the concept of force healing since it pretty much came out of nowhere. Then, I’d have Palpatine kill Kylo by throwing him into the pit. Lastly, I’d have Rey proclaim, “Just Rey,” at the end of the film, and her arc would come full circle.
Firstly, Rey has the Jedi texts, so of course she’d get something from that.
Secondly, killing off Ben at that point misses the point; having Ben heal Rey makes sense from a thematic perspective, he’s fulfilling what Vader started.
Lastly, “just Rey” also misses the point; “Rey Skywalker” is there to show how the Skywalkers’ legacy will live on after the actual bloodline becomes extinct, which is the point of the entire trilogy.
