"Thank you." Wen Ning gives Lightning a serious, grateful look. He doesn't know this woman at all, but she must have meant something to his sister. If that's the case then he feels like he owes her for being there when he couldn't be.

"I'm... really glad she had someone here with her, if I couldn't be." There are others here from his world, sure. Wen Qing hadn't been particularly close with many of them, with the exception of perhaps Wei Wuxian. She hadn't been able to interact with many women around her age, stuck as she'd been doing the bidding of Wen Rohan and then later having to look after their family in the burial mounds - most of whom where those too old to fight. This had to have been at least one positive aspect of her time on the train.
