[--Ah, that's... Celica's expression clearly falls upon hearing his story.]

You told me you had an older sister, but I don't think you told me about the rest of that. [A pause.] I'm... I'm really sorry, though. I'm sure that wherever your sister is, she's thinking about you... and I'm sure she definitely wouldn't think you went wrong anywhere, either. I'd say you turned out just fine.

[Because of his comment though, she's pretty curious as to what kind of person his sister is. She definitely sounds nice, at least.]
