 Tonks:
 
 I agree that Snape is still working for DD. But I have aother 
 question. DD went to Snape when he was injured and wanted Snape 
when 
 he drank the poison. So is this just because Snape is a better 
Potions 
 Master than Poppy or is there something else that we don't know 
 about.  Why is it Snape that DD needs?  Why is it Snape that was 
able 
 to save him?  I wonder if there is more to this that Snape just 
being 
 a good potions master.  Just how good is he?  Better than someone 
 whose job it is to be a healer??  There must be some deep secret 
here. 
 What is it?
 
 CathyD now:
 Because this stuff, this stuff LV uses, is Dark Magic at it's 
finest (worst?).  Stuff only Snape can understand.  Not sweet little 
Madam Pomfrey.

  And Snape is a healer! Think of the scene in the bathroom after 
Harry used the Sectumsempra curse on Malfoy:
 "Pushing Harry roughly aside, he knelt over malfoy, drew his wand, 
and traced it over the deep wounds Harry's curse had made, muttering 
an incantation that sounded almost like a song. The flow of blood 
seemed to ease; Snape wiped the residue from Malfoy's face and 
repeated his spell. Now the wounds seemed to be knitting". 

Could it be that Snape is able to imitate phoenix song? Or if it is 
a true incantation then some very powerful healer invented it(and if 
so where/when/how did Snape learn it) .... or did Snape create this 
spell too? It maybe that since he (as the HBP) created the 
Sectumsempra Curse he also created the countercurse. No matter what 
you may think of Snape, he is a very powerful wizard! I also suspect 
that Snape was LV's Potions Master when he was first in the DEs... 
he may have been the one who created the potion in the bowl in the 
cave. So he would be the one to know any antidote that might 
exisit.   See also my post at

for some other thoughts on what that potion was intended to do.
