Peter was a bit surprised, mostly because he didn't have friends outside of James, Remus and Sirius. It was sort of nice, especially since Billy would have fit right in at Hogwarts among the Marauders. He grins brightly and nods his head.

"Sure, mate. We're friends and one of my only ones besides James. I'm sure there are loads of other people that you'll find to be friends with, too. So, yeah, it isn't all bad here."
