Is there no way to keep Ochii being a Jedi hunter, who was after the Nobody’s because of Rey and her force sensitivity?
That’s a theme that works even if she’s not a Palpatine. Her parents are just Ms & Mr Nobody, but Ochii - the last Inquisitor- went after them because Rey was an awakening in the force. It wouldn’t need explanation for why he was after her and not some other new force sensitive, imo, her being the protagonist works well enough imo… :p
