I feel like there needs to be some expansion of the Leia/Ben moment. As is, it just feels comically abrupt and confusing. I figure what makes most sense would be additional lines for Leia. Even just adding something as simple as “Come home” would add something.
Leia’s “Ben” which distracts him could easily be delivered from beyond the grave. That would probably make more sense than her lying down and force skyping it to him so hard that she dies, anyway. Even Mace Windu, who never learned how to be a force ghost and has been dead about 50 years, managed to communicate through the force to Rey.
The question is, is a bad explanation for her death better or worse than no explanation?
Maybe putting something like “The ailing General Leia Organa” would help set it up, either way.
I also feel like Kylo needs to expound a bit on the fact that he thinks he “can’t go back.” As is it’s just one line tossed in there, pretty close to when Leia contacts him. If it’s established earlier that he thinks his mom has given up on him, it’d be much more powerful for him to be contacted by her.
