So we don’t really see his special powers in this one.
Jackson Rathbone: “Oh no.”

Why?
Jackson Rathbone: “We’ve a lot to do in this film and Jasper’s powers are one of those that you don’t really want to give up right on the onset. I think, hopefully, we get to do the second and third film and by the third film I think it’ll be very obvious. However I think we do a little subtleties here and there. I don’t know if you catch up on them but whenever Jasper meets Bella for the first time inside the Cullen house, there’s a little bit of a moment. It’s a slight, very subtle thing that Catherine [Hardwicke] worked on with all of us.”
