Has anyone else noticed how Pettigrew is always described 
as "talentless" and "weak", yet he has managed some quite impressive 
magic? He succeeded in becoming an animagus for example. Ok, his 
friends helped him, but he did eventually master the spell himself. 
He also killed twelve people with a single curse, which must be very 
advanced dark magic, judging by the way it is mentioned in 
PoA. "Black killed thrteen people witn a single curse" is always 
emphasising how extremely dangerous Sirius is supposed to be. And we 
haven't heard of any other incident where so many people would have 
been killed by one curse. Is there more to Peter than meets the eye? 
Or is it just that he was using Voldemort's wand? Somehow I don't 
think it was the wand. As Mr Ollivander says in PS (p.64,UK 
paperback edition) "Of course, you can never get such good results 
with another wizard's wand."
