"Babbo..." He repeats it slowly- getting used to the word, and of course he needs to, he's never heard it before. But after considering it only briefly, he beams impossibly- "That...that's Italian then? A similar term, but from your main language? It sounds rather nice, if it is alright to say so. I apologize preemptively if I happen to take time to adjust, but at the very least I can say without hesitation that 'Babbo' is fine with me!" he confirms, wing resting on that hand.
