I agree Eddie. It also lines up with what they’re doing with Omega in Bad Batch. So it honestly feels like this is where they should have gone with the story.

I doubt future references to this will refer to her as his granddaughter. I think they’ll keep up with just calling her a Palpatine, if anything.

EDIT: Just realized another thing. The name Rey actually means “King” which doesn’t initially make a lot of sense for a female character. It would make sense, however, given that she is a clone of the Emperor, who is basically a king. How would we feel about reinstating Rey’s name being mentioned in the flashback by her parents? I think this is a better lineup than her getting it from the aurebesh of a Rebel helmet, which most viewers wouldn’t remember let alone comprehend. Children that age would definitely remember their own name. It could be the codename the Sith cultists gave her, like how Omega was given by the Kaminoans. This would be similar to how Darth Vader’s name is a hint to his own character - dark father.
