Rey's still trying to process the fact that Darth Vader gave Kylo advice that seemed likely to help the two of them reconcile when he hits her with the question. She nearly flinches; she hadn't been expecting to talk about it yet. She's entirely too tired for whatever argument they're about to have, now that the adrenaline that came with panic has started to wear off.

Still, she supposes he deserves an answer. It hadn't been a complicated one on her end.

"I didn't want it to be a stranger, and I thought someone I knew, a Force user -- we already know how to get into other people's heads, and how to stay out. There weren't that many choices who were correctly aligned."

She'd offered to tether to Obi-Wan, for that matter, but she'd respected his privacy enough not to push when it seemed he was trying to gently deflect.
