Rey isn't going to argue the point; she and Kylo have to work out their issues with one another on their own. But that doesn't feel impossible anymore now that they've managed a few reasonable conversations. She supposes she has Vader to thank for at least part of that.

"You're not what I expected. I think I misjudged you before."

She can hardly be blamed for that, considering that everything she knew of Vader was secondhand and singularly focused on the negative. But she'd nearly made an enemy of him at their first meeting, and it was only by chance that she'd managed to correct her initial assumptions. She isn't quite apologetic, but there's an acknowledgment in her expression all the same.

"While we're here, if you ever need my help, I'll do what I can."

That doesn't mean she'll do murders for him, but maybe he can stop doing surgery on himself when there are Force healers around?
