Isaac let out a sound that was half laugh, half whimper as he let one hand lightly clutch at Peter's shirt. "That was a good start," he said, managing a grin. "That was definitely a good start."
The snark was gone, and in its place was a willingness to... if not cooperate, exactly, then at least see where Peter was going to take things before he started with any sort of complaining.
No, that was a lie.
He wasn't going to complain at all, about anything. He trusted Peter. He knew that some people -- okay, a lot of people, apparently -- would say that he shouldn't, but they could go fuck themselves. They'd never bothered to care.
