Something just occurred to me. When Kylo reveals the “truth,” he’s in the mask. Similarly, we can hardly see Palpatine’s mouth when he talks. Does Rey even say out loud that she’s a Palpatine? I don’t remember. Part of me wonders if this was something added in post production, and if they actually gave Kylo the mask back because they knew that part of the script was going to keep getting changed.
Anyway, since he’s in the mask, that’d make changing his dialogue a bit easier. But what would he say instead? And what would we have to work with (Lego TFA??)? Truthfully that whole section of the film is a mess, the Palpatine/Kylo/Rey stuff. Doesn’t make a lick of sense. But I’d hate to lose their Force talks, and especially their Force duel which is one of the coolest things in the film (brief as it is).
The question ultimately being, might it actually be possible to remove Rey Palpatine? Keep her a nobody, make it so that Palpatine simply saw Rey’s future/sensed her power/whatever? That’d be the only way I think to preserve the narrative (of course it’ll still suck to some extent because even though she’ll be a nobody she won’t be random, you know?). I fear what it might do to her character in this film a bit (what makes the dark side temptation so fearful?) but it’s not like her character is coherent in this anyway.
