> 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.

Bookworm:
Snape accuses Sirius of attempted murder when they were 16. 
Depending on when Sirius' birthday is, he could have been 16 by the 
end of 5th year. If the Prank occurred prior to the Pensieve scene, 
it would possibly explain Lupin's lack of reaction. Given the way 
Snape attacked Lily Evans ("mudblood") what would he have said if 
Lupin had tried to help – possibly call him a werewolf in front of 
all the other students?
