Rey shrugs, not having sat down and discussed all of this at length with Luke yet. They were still getting to know one another; prying into tether-acquired knowledge didn't seem kind unless it was something urgent.

"So far it's only particularly intense, immediate things. And we can tell where the other person is -- though I'm not clear on whether that's because of our tether or because we're both Force-sensitive, or if one makes the other easier. We haven't tried to communicate intentionally yet."

She's been reluctant not least because her bond with Kylo was already plenty to deal with, though she supposes it would be worth testing just to see. If one of them got into real trouble on a mission they'd want a way to communicate, after all.
