Removed talk about Leia (and possibly Luke, depending on one’s interpretation of the scene) having known about Rey being a Palpatine. In this version, Luke essentially tells Rey, “So what if you’re a Palpatine?” It also seems to make a great deal more sense to assume they did not know this during the events of TFA and TLJ, with Luke learning this postmortem.

I disagree with this. The point of the thing with Leia is for Luke to show to Rey that just because she’s a Palpatine doesn’t mean others inherently hate her for her lineage; it’s part of her arc of overcoming her toxic core belief that she is worthless, she’s developed that core belief during her time on Jakku after she was abandoned.
