He catches that glance. He wonders if there's any conscious meaning behind it, but for now, he doesn't dare assume. He'd had that thought, before they arrived here, that maybe once Rey knew what had really happened to her parents, she might be willing to work with him in taking Palpatine down. That maybe she would be willing to join him then in the way that she'd refused before. He can't help wondering if that vision Rey's had might mean he was right, even if it scares her now.

"He told me to kill you. To end the Jedi for good." That was what Palpatine had said, but perhaps the truth is that he had seen just what she could be capable of, and that he was protecting himself from her. He had also claimed that Kylo would rule as the new emperor, but Kylo didn't believe that Palpatine had any intention to hand over any of his power to either of them. He glances to his grandfather, looking for any insight he might have.
