What’s the problem with Rey’s vision of seeing her parents leave in a spaceship? I’m sure that would be extremely traumatic. Why do they have to be important people simply because she saw them leaving? Yes, the way it was setup left the audience wondering who are those people, and if we knew them. But the characters weren’t giving any fucks at all, except for Rey. I don’t see what’s the big deal about it. Simply because we saw them leave, it doesn’t make them more important or less, or changes who they are.
They were junkers that sold her for beer money but had a fancy ship they could leave the planet on? I guess they could have sold her for passage off the planet but Kylo says they are buried there on the planet.
I assumed the ship crashed. I honestly didn’t even consider it a potential discrepancy, I mean I suppose there is room for different interpretations (and who knows maybe JJ will incorporate the parents somehow?) but either way I don’t think it’s that big a deal.
Furthermore, it is implied Kylo knows her (or at least JJ was leaning that way). Besides the “what girl” line, in the novelization he says to her in the forest “it IS you!”
“What girl” is precisely because he doesn’t know her - “why is there someone else on Jakku who would be helping the droid escape and a kid, no less?”
When he says “It is you” he’s referring to the awakening he and Snoke felt. This is really the only reasonable interpretation in the context of not only TLJ but just TFA by itself. The line doesn’t make sense in any other way, unless you’ve built up an elaborate alternate completely unspoken of series of events in your head. (It’s likely they cut it out of the film because people would read things into it that weren’t there)
