So I was thinking about Tonks's wonderful defense of Lupin posts, 
and a thought occurred to me.  (Paramedics weren't necessary but it 
was a near thing.)  The night of the Shrieking Shack incident in 
PoA, Snape, as we know, appears in the Shack.  He tells the group 
that he found out what was happening when he went into Remus's 
office to give him his monthly wolfsbane potion and saw the 
Marauder's Map.  (PoA p.358 US). As soon as he grasps the situation, 
he goes tearing off to the Shack.   But wait a minute-what about the 
potion?  Why didn't Snape bring it with him?  

Angel adds:

I'm sure that the potion has to be drunk before it stops smoking. It's
earlier in the story. We don't know what makes it stop smoking, but it
might have become ineffectual by the time that it gets to the shack. 

I'm guessing that he saw the non-smoking goblet, and panicked. (need to
re-read PoA)
