Morgan Braden- Newborn Vampires

One thing that really stood out to me while reading the part of Breaking Dawn when Bella is a newborn vampire is that she was very tame. The other vampires point out the whole time how Bella "should be" acting as a newborn and she turns their expectations around and is very controlled. My question is why did Meyer make Bella the exception? She's always been the ordinary one, the predictable one. I think Meyer is tired of having her heroine be too plain and wants to bring in some life to Bella's character...(about time). Also, the way that Meyer portrays time through Bella is very odd. Bella kept saying that "one fourty-fifth of a second passed" and phrases like this so that readers get the idea that this is unremarkably fast. Too fast for us to even understand exactly how fast it actually is. I'm curious to know how the movie will show this to the audience without it looking too unreal. Unfortunately, they haven't done such a great job of this in the past so I suppose we will all have to wait and see.
