Hi there!
I know this is kind of late but i had to say something.
I was watching CoS the other day and i couldnt help but notice one particular girl.
In the scene where Mcgonagal (sp?) is telling the class about the chamber, there is a girl sitting behind Draco and beside Crabbe (or was it Goyle?)
Anyway, in the next scene where Hermione, Ron and Harry are walking own the corridor, Draco, Goyle and Crabbe push their way past the, and the mysterious girl is following them.
Was I the only one to catch this? Check the dvd and you'll see for yourself. I think that girl is Pansy.

Bye!~!
