Peter would have probably lost it to the wolf again if his wolf knew how happy that made Flynn. He just wants to be your best friend, buddy!

"Well, I mean, if you're not used to being around...uh..." he didn't want to say big animals, but. "Critters, you wouldn't have known. Did you grow up with a dog?" He grinned, though. He liked to work out, and it was something of a point of pride that his wolf was big and muscular. "Was I really buff? I mean, as a wolf. Can wolves be buff?"

"Cool! Research!" Peter gets up, ready to follow him around like an eager puppy.

Really not that much behaviorally different than he was when he was covered in fur.
