That must have been a very interesting piece of the floor Rhys was staring at but he ignored it in favor of just listening. So Rhys was apologizing - really apologizing. Not just the weak 'I'm sorry's they'd gotten at the club that night. And he was trying to be a man about it instead of a child. Good for him.
Although the majority of this conversation was for him and Amadeus, Ariel did take the moment to nod in acknowledgment of his portion of the apology. That was all that needed to be said - for now. If he ever did it again, the wolf would make him pay for it but he figured Rhys probably knew that by now. As it was, for now, he stayed silent and let the two Tremere talk. At Amadeus's admission, the corner of his mouth perked up, knowing that admitting he was wrong wasn't easy but again, Ariel said nothing, did nothing. It wasn't his place and he doubted Amadeus wanted him making a big thing out of the moment in front of the kid anyway.
