Irrelevant, but have you read my Rey Palpatine defense yet?
Now that you’ve asked, I just have. I agree that it doesn’t necessarily contradict the decision in TLJ, but I agree with the other responses that Rey’s arc around accepting that her heritage doesn’t define was mostly completed in TLJ - she just needed a film where she finally gains confidence in taking on the Skywalker mantle (which she does in TROS) and not a whole new plot development. I mostly dislike the Rey Palpatine decision because I love when Star Wars has an everyman/woman theme around standing up for what’s right, and Rey Palpatine means Rey doesn’t have her own power but “his power”, as well as reinforcing the feeling of the main star wars characters being interconnected within this small, elite group.
But as I say, I agree that it doesn’t contradict the theme about Rey learning that heritage doesn’t define her.
