In PoA, DD tells Harry:

"Pettigrew owes his life to you.  You have sent Voldemort a deputy 
who is in your debt. . . . When one wizard saves another wizard's 
life, it creates a certain bond between them . . ."

This being true, James and Snape must have had the same bond.  

DD continues:

"This is magic at its deepest, its most impenetrable, Harry." (PoA, 
427, Am. ver.)

So what exactly happens with this deep magic, impenetrable bond when 
the wizard who was saved is responsible for the death of the one who 
saved him?

What happens when Snape relates the prophecy to LV and causes LV to 
go after and kill James, the wizard who saved Snape's life?  


Ginny343, who has decided "for now" to agree that while some DEs 
knew about Peter, Snape did not.
