Almost anything in that direction would be preferable to what was there, but yeah… pie in the sky it would seem.
Since Kylo was considerate enough to be wearing his mask, I wonder if his line “I never lied to you” could be replaced with something like “You were right.” It would be more consistent with the idea that he had previously only looked into Rey’s mind, and got her to admit what she already knew deep down. (And Rey saw his intentions about her and Snoke.) Stating he never lied would seem to imply he knew before.
It’s a line that definitely needs to be cut, regardless of parentage. Clearly it was a line made only for the audience’s benefit, based around a misconception of how TLJ played out. It was Rey who said her parents we’re no one, Kylo provided information that was a “lie” (sold for drinking money). Clearly just the writers being like “oh you think he might be lying? We’ll do you one better, he’s not lying and there’s more to the story” without actually paying attention to what happened. It’s one of the many things that make me wonder if they even saw TLJ. I long for the days of Rian Johnson, who I think outright stated he “forensically analyzed” certain scenes to make sure he wasn’t contradicting anything with his parentage reveal.
