Well I will have a go at putting you out of your misery

. No that bit wasn't in the book and wasn't mentioned later on. I think it was just to demonstrate what a rotter Draco is ie stealing someone else's Christmas present.
But that is what I love about films like Harry Potter - you can watch them over and over and still spot something new every time. I am still playing the scene in POTC2 over and over again in slow motion where they visit Tia Dalma for the first time. Jack steals something and looks at other bits and I know they are all tied up with Davy Jones.
