Rey would argue she barely knew Kylo -- they've only managed to have approximately three reasonable conversations with one another -- but she can't actually deny that she cares for him. And being Force-bonded to him isn't likely to make that less true.

"Leia's a good leader, but the past year has been hard on her. And Kylo -- honestly I have no idea what sort of leader he is. Or would be, if the First Order's goals were more aligned toward peace. He took over for a tyrant, and I don't think that role suits him."

A part of her regrets walking away from him. There's a chance the two of them might've brought about an end to the war by now, and with fewer losses.
