Just Cloud is fine. [A bit of sadness comes to his eyes as he finally figures out Alisaie's place among the Heroes.] I see...I'm sorry about all the others that were lost. It's good to have you back with us at least. And thank you for watching over us in Aqures Tosf.

[He then gives Kupni a nod, impressed with the moogle's initiative.]

I guess we just gotta get you moved in then. Again, sorry about the mess. I'll take care of it.
