houyhnhnm:

In terms of what is said, it is very ambiguous.  However there are at 
least three lies or omissions that Snape tells Bellatrix (or fails to 
tell her)

I think it shows what it means to be a spy.  We finally get to see 
what it is that Snape does.  

I love the title--Spinner's End.  Why "Spinner's End", why 
not "Spinner's Row". The spinner of lies, for all his virtuosity, has 
met his end.  He is caught in his own web of deceit. I think it 
shows "loyal death eater" is NOT one of the possible explanations for 
Snape's behavior.  Because what takes place that day is not the end 
for him if he is, just another opportunity.

The other two possibilities are that he simply loves the power of 
playing the game OR he has remained loyal to Dumbledore.  I favor the 
latter even though JKR doesn't give much encouragement.  I've wanted 
to see Snape redeemed ever since seeing the teenage Snape in the 
pensieve.  The description reminded me so much of a student I once 
had.
