Please say more, Andrea, because I also have a hard time 
understanding this scene.  I get what Harry thinks and what Snape 
thinks (possibly--it's not at all clear to me whether he suspects 
that V comes into it somehow, or whether he just thinks Q is trying 
to get the Stone for some more mundane reason; I lean toward the 
latter).  What I don't get is what Quirrell thinks Snape thinks.  
This is key now that we all want to know how much Voldemort knows or 
suspects of Snape's true loyalties.  Can Snape plausibly claim to be 
loyal to Voldemort, or has he given himself away with his activities 
in PS/SS?
