> I seemed to get the impression from the books that Snape was an 
excellent potions master. I don't think it would be too far-fetched 
for Voldemort to want Snape for that. If you were an evil wizard 
planning to take over the world potions could come in pretty handy. 
But that's just my opinion.



Alla:

OK, then let's go back to my original question. What cover Snape has 
to maintain by being nasty to Harry?

If Voldemort want Snape for his potion making skills, Voldemort will 
still want Snape to pretend that he is loyal to Dumbledore.

How is being nasty to Harry shows to Voldemort that Snape is loyal to 
Dumbledore?
