Did you notice...

That in New Moon in the part were Bella arrives school taking some pictures of her friends, were then enters Edward and lastly comes Jacob, that Kristen was going to say something but it was totally obvious that it wasn't in the script? She was like

"Jacob!" <- It was in the scrip, but then she says something like "Wha..." <- Like if she was going to say "What are you doing here" or something like that, and while sayin this, she made a really funny face like saying "I wasn't supposed to speak here".

If you haven't... I recommend you to procurar for it! Is really funny! XD
