He nodded and sat down opposite her, wondering what it was she wanted to talk about. She appeared more nervous than he'd expected, she couldn't be worried surely? She knew he'd do anything for her didn't she?
His eyes widened when she revealed that Rey was her daughter, he'd had no idea Leia had another child. He'd have been about thirteen if he was guessing Rey's age correctly but it made sense he didn't recall her, as Leia said he was on Yavin IV at that time. And by the time she was abducted Poe would have been training to become a New Republic pilot, he'd never witnessed his fathers upset which was why Leia's next words hit him hard.
"My half-sister?" he repeated with a small confused frown, "But...how...I mean, what happened?"
His father had left the rebellion behind, they'd had a home on Yavin. After his mother died his father only left for brief periods of time for supply runs and...and to check in with old friends, he realised with a start. Leia was one of those old friends and it seemed Kes Dameron had done more than check in with her.
