Tony felet a pang of guilt when Peter takes his explanation so easily. The kid shouldn't have so much faith in him.

"Pete, it's okay," he says, waving away the apologies. "There's a lot going on, kid. Thanks." He takes the shirt and puts it to his head.

It didn't really help, as he was pretty convinced at this point he had completely lost his mind.
