Hi... If this idea has already been dicussed just let me know... 
anyway... Snape was a DE (no suprises there) but when he become a spy 
for the "old crowd," would he not reasonably have revoked his ties 
and friendly associations with the DE's?... Yet, as is so often 
brought up, Draco is his favorite student... Though it is mentioned 
that the DE's were sometimes unaware of their own fellow members, 
isn't Lucius Malfoy a confirmed DE (even if he was cleared). Why 
would Snape, already having the guilt for being a former DE, be so 
biased towards Malfoy?... I would assume that Snape would distance 
himself from any interaction or associations with DE families... It 
just seems sort of odd...
