“You’re a Palpatine” isn’t great either. Maybe cut both? So he says “You have his power,” Rey reacts, and hes goes on with “My mother was…”
Might cut the scene too short though, and it’s supposed to be the huge dramatic reveal.
I would be cool with that too… maybe that’s why I have an aversion to it, like the audience isn’t that dumb as Kylo basically told us three times in a row that she’s Palpatine’s granddaughter… like, we get it lol
