I wasn’t making this for Ascendant, just testing out some lines for a Rey Nobody edit, but I was planning to replace the “Do you still count the days since your parents left?” line with something relevant to this. It works fine for a Rey Nobody edit, but I liked the idea of paralleling Kylo’s cracked mask with Rey’s cracked lightsaber. And also play into her identity stuff.
He doesn’t see the actual blade in this scene obviously, but he sees the hilt on her waist, and sees she has repaired it.
I still think AI Kylo should replace some of the lines he tells her on Pasaana.
Considering the fact that Kylo should know at this very moment that her parents didn’t abandon her and instead just wanted to keep her safe, it’s not something that he should be getting her all rialed up about. There are other things he could tell her about her inner darkness to really set her off. Such as her lightsaber, as you’ve pointed out, or even that old line we had been considering: “My mother doesn’t see the darkness in you. Your friends don’t either. But I do.”
