Change Kylo Ren’s line about Rey’s parents being buried in a pauper’s grave in the Jakku desert into:

They were filthy junk traders who sold you off for drinking money. They’re dead, their ship crashed into a pauper’s grave in the Jakku desert. You have no place in this story, as such, there was no reason for your parents to abandon you. I told you, they threw you away like garbage. They did. You’re nothing, but not to me.

(No, I’m not saying go back to TRoS and change it so Rey killed her parents, just that it malfunctioned or something.)
