He's frustrated more than angry. It takes a lot to make Peter angry, but the idea of somehow being pushed into making a statement like Lydia's, when he's sure there's a lynch mob here just waiting for the right catastrophe... It was trying, at the least. But, then Isaac's eyes are gold as they look into Peter's blues, and he can feel the wolf lurch inside of his body, despite that it's a week from the fucking full moon (it's one of those nights where he wishes that it wasn't). His body tenses, but his stance shifts lower, his head bows; non-aggressive. Peter is a werewolf, but he's not a fighter, not if there's any other choice.

But then that glow of his eyes catches him completely fucking off-guard and he stares, looking at Isaac, completely shocked out of his frustration. "Woah." Isaac's eyes are the same glowing gold as his own when he turns, but it's the wrong moon and he's not shifting.
