zgirnius:
Indeed it has. If you go back to post 132908 and onwards, the very 
first post after the list reopened post-HBP release had SNape in the 
thread title. (One of many, many such posts...)

Not that I object to discussing it again, but you might find it 
interesting to look back at some of 'em.

zgirnius:
I mostly agree with you, about Snape, Dumbledore, and Lily, except 
for this rather important detail. I think Snape became Dumbledore's 
spy during the first war, well before Voldemort killed the Potters. 
(My ownb guess is about a year before). Dumbledore does not state 
Snape felt remorse over Lily's death, but over *Voldemort's 
interpretation of the prophecy*. In GoF, Dumbledore clearly states 
(in the Pensieve memory of Karkaroff's hearing) his opinion that 
Snape spied on Voldemort "at great personal risk".

I think Snape approached Dumbledore with news of Voldemort's plans to 
kill the Potters before they were dead, in an attempt (ultimately 
doomed by Peter's betrayal) to protect them.
