I always thought it would be interesting if we found out that she killed her parents the same way she “killed” chewie, maybe she was born with the darkside and her parents hated her for it, they decide to sell her to unkarr and leave the planet but in her rage she force electrocutes the ship, she becomes so traumatised that she locks those memories away, in TROS we see her true nature unravel as the film progresses until we reach the climax where she must make the ultimate choice.

In my own reedit this could actually be done, since I’m not going to be including the whole scavenger hunt. It would be possible to combine a shot of young, abandoned Rey reaching out her hand to the sky, with the TROS shot of Force-lightning exploding the transport.

I think I’ll make this a flashback during Rey’s interrogation. New dialogue could also be created for Kylo in which he says as much. Something as succinct as “You killed them.”
