Angie again:

Wow!  I never dreamed of so many responses to this!  Like, Carol, I 
read all of the responses.

Interesting theories, all.  I can appreciate the theory that Crouch 
Jr. viewed Snape as a Death Eater who got away and therefore, viewed 
him as a foe.  Who knows, maybe LV complained about Snape to Crouch, 
Jr., although, I admit there is no canon to support that.  Guess it 
all boils down to whether the Foe Glass sees one's true enemies or 
one's perceived enemies.  

I believe the Foe Glass shows one's perceived enemies -- otherwise, 
it would be omniscient -- it would know not only the true nature of 
the person possessing the glass, but the true nature of every other 
person/wizard in the world.  And if that's the case, then it WOULD be 
reliable, would it  not?  I see no support for that in the canon.  
Rather, the fact that it is not reliable supports that it sees one's 
perceived enemies.

Perhaps the type of magic that powers the foe glass (or similar 
objects)is like computers.  Garbage in, garbage out.  It is only as 
reliable as the wizard's knowledge of a situation.  Wizards are 
human; therefore the magical objects they create are subject to  
magical human error.

All in all, I think the Foe Glass episode says more about the 
unreliable nature of the Foe Glass (and perhaps all similar 
magical "indicators"?) than whether Snape is truly DD's man.  If that 
is the point, I wonder if the theme will rear its ugly head in Book 7?
