Now me:

I think this is explained in PoA when, in the shrieking shack, Sirius 
says to Pettigrew (liberal translation - I don't have the book with 
me) "You couldn't go back to the DEs because the DEs believed the 
double-crosser double-crossed them" since Voldemort met his downfall 
in Harry based on Pettigrew's intelligence as to the Potters' 
whereabouts.  And Sirius says that Pettigrew wouldn't go back to 
Voldemort until Voldy "was the biggest bully in the playground."  
Sirius also says that Pettigrew wanted to be with a well-connected 
wizarding family like the Weasleys so that he would be able to learn 
when Voldemort did in fact become the "biggest bully."

Sirius' comments intrigue me, because they imply that Pettigrew knew 
that when Voldemort tried to kill Harry, he would lose his powers.  
In the graveyard scene in GoF, when Pettigrew is sobbing over his 
bleeding arm stump and Voldemort is debating whether to give him a 
new hand, Voldemort calls Pettigrew "worthless and traitorous."  Does 
this suggest that Voldemort also believes that Pettigrew knew that 
Harry would be his downfall?  I can't think of another instance in 
the books where Pettigrew did something that Voldemort would 
consider "traitorous" (unless it's simply that Pettigrew didn't try 
to find Voldy for 12 years).  

And if Pettigrew did know that Harry would be Voldemort's downfall, 
how did he know?  How could he know in advance that Lily would 
sacrifice herself for Harry and that the AK would rebound and hit 
Voldy, destroying his powers?  Did Lily tell him she planned a self-
sacrifice?  If so, then both Lily and Pettigrew must have known that 
the sacrifice would save Harry's life and destroy Voldemort's 
powers.  Seems a stretch!  But perhaps while Lily's sacrifice saved 
Harry's life, but it was something "special" about Harry that 
destroyed Voldemort's powers when the AK rebounded (the power of the 
heir of Gryffindor, perhaps)?  So did Pettigrew know that Harry was 
the heir of Gryffindor (this is less of a stretch since he was good 
friends with James)?

Any thoughts??
