Now that the shock of the transformation's settled, the other differences are becoming clearer. Scott's aware of that same stark contrast that Isaac is, and somehow seeing it like this - even more intense, more different - creates a strange surge of... not jealousy, exactly. It's more like disappointment, a detached sense of loss at the fact that they got something so much worse.

He watches while Isaac reaches out to pet Peter, and it takes a few seconds for him to register that lost look he turns towards him a moment later. Once he does, he kneels down next to Isaac, reaching out to more confidently run a hand over Peter's neck. He still smells like blood, but this - whatever it is - is distracting enough for Scott not to fixate on it.

"Did Derek ever tell you about his sister?"

It's a completely random comment. He realizes that a second later, but he's still distracted by Peter when he elaborates.

"I think she could do— this. Turn into a wolf."
