I like that thought process Testing. I do believe the reason Rey’s father is never mentioned as being a clone in the original movie is because of what you said: “a familial, hereditary connection between the two solidifies her belief[s]”. While my original plan was to make the clone side of things even more apparent, what you said here has definitely made me consider going in the exact opposite direction. The biggest question from such an idea is this: who is Rey’s grandmother? Just a random Sith acolyte woman?

Furthermore, when I said my original plan was to lean into the whole clone side of things, consider this. I was going to alter Kylo’s dialog to be the following: “You’re his daughter. My mother was the daughter of Vader. Your father was a clone of the Emperor.” Therefore, technically speaking, doesn’t that make her even MORE like Palpatine? As in, would you rather be Hitler’s grandchild or his child?
