I feel like the best option, if possible, is to cut references to Rey’s parents being good people in TROS. Rey can want revenge for being orphaned even if her parents weren’t the best, which might even better sell her dark side arc by having her want purely selfish revenge instead of avenging good people. And her brief moment of “my parents were strong, they saved me from you” in the Palpatine confrontation doesn’t really matter since it’s Ben and the Jedi who actually help her, and not her parents’ love. Heck, she takes someone else’s last name in the final scene, so her parents suddenly having significance to her again doesn’t even fit in the context of TROS itself.
