Rey’s natural inclination towards the darkside and its Ramifications on her character and the plot need to be adressed. 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, when 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.
That’s a good idea too. Rey killed her parents. We see Rey’s visions of her friends dying. First Kylo tells her he buried her parents bodies on Jakku. She interprets this as he murdered them. He later reveals she’s the one who killed her parents. We then see Rey’s future visions again of her friends dying but this time see her as a Sith. In other words she will be responsible for their deaths.
Maybe the action of killing Chewie triggers a vision of her doing the same thing to her parents.
It’d sync especially nicely with the shot we see of them flying away. Technically near-impossible maybe, but it’d be great to see her pull their shuttle out of the sky (with lightning) in the same way she tries to grab the shuttle Chewie’s in.
