father.  That makes sense to me.  What I do not understand, however, 
is the favoritism he shows toward Malfoy.  If Snape has indeed 
turned his back on LV and the DE, why does he favor the son on a 
known DE?  It makes me wonder where Snape's true loyalties lie.  

Casey:
Maybe because Malfoy is a brown-noser? I mean he's the son of a very 
wealthy, highly respected, old wizarding family, and he shows Snape 
a lot of respect. Harry doesn't, he back talks and argues all the 
time, which, in Snape's mind, makes him arrogant like James was.

Snape was wrong in the beginning but Harry hasn't done anything to 
disabuse Snape of his first impression.
