Foreshadowing?

[Kate]

Hi, I have never posted on this board so if this has been posed 
before I appologize.  I wanted to post it to the HPFG main board but 
I thought that I would be yelled at for it being more about the 
movie.  JKR said that the Prisonor of Azkaban movie foreshadows 
things to come int he series and that readers would think that some 
things that are going to be revealed are really hinted at in this 
movie.  Here is my question:  In the DADA class that Snape subs, he 
asked the characteristics of a werewolf.  Hermione answers with a 
few various facts and then says that werewolves only respond to the 
call of their own kind.  This REALLY bothered me because later in 
the movie, Hermione (during the Timer Turner scene) calls werewolf!
Lupin and he goes after her howl...  Does this mean that Hermione is 
going to be bitten by Lupin in books 6 or 7?  Has she already been 
bitten and we don't know it?  I find this latter possibility hard to 
believe since surely we would have seen signs of it after 5 books... 
but possible I suppose.  Surely that isn't just script slip up...  
Hermione is always described as "bushy" (like fur?), maybe this is a 
hint?  Any ideas?

Thanks,
Katie
