Peter Pettigrew: has a silver hand (yeah, maybe it was just silver-colored, but I choose to believe it was actually made of silver)
Remus Lupin: is a werewolf
Am I the only one who was hoping that Peter would do something hardcore like kill Remus by ripping his heart out of his chest with his silver hand? Silver bullets that are *fingers*, the fingers of one of his former best friends, ripping his heart out! Ripping his heart out *again*, really, this time literally rather than like before when Peter just killed/betrayed everyone Remus ever loved! Come on, you know it would have been awesome.
