Oh, and I should clarify that the reason I think this Rey background change necessary is because in order to fit in the Vader duel and Luke scene I have to remove 2 instances of Palpatine reminding Kylo and the audience that he wants her dead. At that point, it’s best to just play into the idea that there is some level of truth to him never wanting her dead.

Immediately after Palpatine reveals her true nature to Kylo, the audience can assume that Palps tells Kylo that should he fail in killing Rey, that she will kill him instead and inherit what he could have had. This is reflected in another updated Kylo line: “Palpatine wants us to fight” instead of “Palpatine wants you dead.”

So the premise is that Palpatine wants them to fight each other so the strongest bloodline becomes his heir. Granted, this will never be explicitly stated since I have no intentions of further modifying Kylo’s reveal scene for this edit.
