Honestly, I feel TFA did resolve the whole parents issue. “They’re never coming back.” Bam. Done. Endgame. Nothing else needs be said. TFA never plays up their identities as a mystery. They’re nothing more than a plot device used to hold Rey back, to keep her from “accepting the call.” They’re an anchor around her neck, pulling her back to Jakku, and causing her to push away the actual family she is cultivating: Finn, Han, Chewie. So I honestly have no idea why fans obsessed over this for two years. I just rolled my eyes and crossed my fingers that no one would be stupid enough to ruin all of that and make them Luke Skywalker or some other such nonsense.
Obviously TLJ does tease the audience with this, with the expectations the fans have. And I’m okay with it here since it ultimately just serves as the perfect “pulling the rug out” moment, both for Rey and for the fans who pointlessly obsessed over something they could never hope to be right about. TFA didn’t create this obsession over who Rey’s parents are. The fans did.
