Congratulations, Chris is feeling an emotion! It's... like, stunned, or something. He's not sure where to go from here, exactly, or how to swallow this new information. Moira's presence is only creating more questions that he doesn't have answers to, and as much as he likes the kid, he doesn't like not knowing why Barry Burton's fucking daughter is here or what she has to do with any of this or how both of them got here in the first place.

His face is an open book at the moment, and it's not a pretty book. He mainly looks like he's recently smelled something disgusting- no offense to her, it's just his deeply confused and conflicted face, apparently. Where does he even start?

How about starting small? "Uh..."

Okay, not that small. "How have you been?"

Yes, she is in the best hands.
