Lunasa:
I was thinking that myself actually. And everyone one involved got 
punished. All four kids got points taken away for snooping about the 
grounds in the middle of the night. Or was it detention?
Even if Sirius' trick was just along the lines of telling Snape 
whatever was in the Shrieking Shack was far too dangerous for him, you 
can be sure the first thing Snape did was rush off to  Dumbledore. If 
Dumbledore didn't find out that Sirius and James were animagus until 
PoA, and Lupin was meant to be keeping the Shack and his conditio 
completely secret, how did James and Sirius explain away their presence 
in the Shack on a full moon?
