> Who says that he doesn't know that Lupin is a werewolf?  This 
memory occurred during their OWL exams, which take place very near 
the end of the school term, so it would stand to reason that Sirius 
has already played the prank on him....remember that they have by 
this time become animagi...Sirius basically calls Wormtail a 
dunderhead for not knowing the ways to tell a werewolf because he 
has been running with one.  So it is very possible that Sirius has 
already played the prank on Severus and he already knows that Lupin 
is a werewolf by the time this memory takes place.

Additionally, Snape was the one who made the potion that helped keep 
Lupin from turning into a werewolf.  This verifies that Snape does 
indeed know he's a werewolf... he just may not have yet made the 
connection about their nicknames.
