She still can't quite wrap her head around Héctor having been a Hollow once. She's so accustomed to it being a one way street. You go that way and you don't come back. So every time he mentions how he felt as one of those things--or what he said, it jars her a little. She can't imagine it, even with him explaining how horrible it was. So she just grips his hand tighter and holds on to steady him. It's all she feels she can do in that moment.

"Do you think they could be trying to replicate what that girl did? That they're trying to fix him?" That might make sense... She can't deny that she wants to know, too. If there was a way to cure Hollows instead of destroying them... She can't say that all of her clan would be behind it, but she certainly would.

When he asks where the boy lives, she hesitates a little, but ultimately responds. "I've seen him go into Lumière. His room is on the third floor." She already mentioned that she's been watching him, so the fact that she knows where he lives shouldn't be a surprise.
