We see the new Bella in an entertaining sequence when her husband, Edward Cullen ( Robert Pattinson ) , takes her on a test drive, so to speak, as a vampire. She can run from place to place instantaneously, see details of nature in great and speeded-up detail, win in hand-to-paw combat with a mountain lion and has a taste for blood.
That point is made in a scene when she and Edward see a mountain climber slip and dangle from his rope. In a flash, shes climbing the mountain barehanded, and my hopelessly idealistic assumption is that she was racing to save his life. Not precisely.
