Cute! I like it. People are always so determined to cast Peter as evil in their stories. They don't get that he's not necessarily evil, just somewhat weak-willed. I think if Voldemort hadn't come along he wouldn't have felt the need to be "on the winning side". He's not very brave, and he always tries to befriend the biggest person he can find. I also feel like it's partly Sirius's fault for just dismissing him like that when Peter became the Secret Keeper.
