Snape, Dumbledore and Lupin

Hi everybody, here is a new poster who was just asking himself about 
Dumbledore's lack of reaction concerning the fact that Snape informed 
(as Lupin himself states it at the end of PoA) the students' parents 
of his "werewolfsness" ; something that, as a consequence, led to the 
latter's getting fired and prevented him from hoping for another job
(as far as I know, Dumbledore did not really manage to keep him as in 
Hogwarts). 
That surely means (as we have begun to aknowledge it in GoF and OoP) 
that Dumbledore relies heavily on Snape but at the same time he 
refuses to give him the job of professor of defense against the dark 
arts however skilled and well-suited for that job he may seems (save 
Dumbledore and Voldemort, he is probably with Bellatrix, of course, 
the one character that best knows what you got to learn in order to 
master the dark arts ; and remember, as Lupin himself tells Harry in 
OoP, he is as well "a superb occlumens" - and there are only three 
known occlumens in the book, Snape, Dumbledore and Voldemort : that 
definitely sets him apart from the other wizards (including the 
DEs)). 
There must be something about Snape and Dumbledore that we 
don't know yet. What do you think that might be ?
aam.
