For a god-child to join in a conversation of god she/he wasn't invited in is seen as disrespect to the gods present, she had indirectly step on the God toes she had offended few moments back, what the hell happened to her luck today
Moro only shot her a glance but didn't take it to heart, what brought him here is more important than teaching little god-child her place, but Nino was secretly praying to his star for the former not to purnish this rude daughter of her too hard
Both of them are gods but truth is they are not in the same level or realm, no other god present is at the level of Moro standing before him, thought Moro sees him as friend,he knew his place, those at Moro level would level an entire planet with just a flicker of their finger talk more of moving their entire hands
