4tnz has a little interview with Ashley Greene who talks about Taylor, as well as Rob becoming a flittering image in New Moon!

“Of course they threw Rob in there! He comes in as a flittering image to tell Bella not to do anything reckless and then you have him at the very beginning at school, at the party when he’s saying goodbye to her and the flitterring images and in Italy as well, so they’ll get their fix.”
