[Childe picks up on the tone of voice Roxas uses. There's more confusion there than anything, and the way he asks...is he correct in assuming that the guy doesn't know what siblings are?]

Haha...I suppose you could put it that way, to a degree. Though I would say the bonds of family far surpass those of just friends. They're very important to me; and where I come from, family is always first.

[Meanwhile, Childe is trying to figure out how to ask Roxas if he knows what siblings are without being rude.]

But let me ask you this; do Nobodies have anyone they would consider as a brother or sister?
