If there was some other man at GH and Voldemort had killed him (or,
in fact, cursed him in any way), then his "echo" or the echo of the
curse would have emerged *between* James and Lily.
 
Snow: If this is a true statement, then where is the echo of what 
happened to Harry that should have been in front of Lily's echo? I 
had wondered about that when I saw that the hand for wormtail had 
been produced as an echo. Wouldn't we have at least heard screams?

Naama:
Since that wasn't the case, and there was somebody else in GH, he 
must have been a collaborator. Which kind of makes the whole dramatic 
secret keeper, betrayal, and Voldemort's attack a bit redundant, no?

Snow:
As DD would say: Yes and
 No. It's a clue that without all the pieces 
is nothing more than a fragmented bit of information. All we truly 
know is that Voldemort, Lily, Harry and a man's voice telling Lily to 
run were at Godric's Hollow. The rest is supposition.
