movie question that's kinda confusing (from main list)

[Jennifer Piersol]

As movie discussion has been "banned" on the main list, I 
reconsidered my automatic reply there and decided to reply to *this* 
list.  Aren't I a good girl?

Here's another point to ponder... along with their Forbidden Forest 
detention, Harry, Hermione, and Neville all lose 50pts each for 
Gryffindor.  Is that going to be taken out, too?  It seems to me that 
it would be fairly important, as it would be the reason for Slytherin 
to be the original winners of the house cup at the end of the year.

What would be the point of the crowd (and esp. Neville) earning their 
bravery/logic/chess points if they weren't behind to begin with?

Jen (who is hoping that there is another instance where they can lose 
their points and get detention that's *plausible*)
