Why because he would be the most likely to do it out of all the cullens, lets face it he is not yet in control of his hunger and finds it hard to deal with the sight of blood. I give you Jasper Hale he bit me
It was April,1912, i was on board the U.S.S Titanic and fell overboard and hit my head while stopped at a port. i had severe hypothermia . i was taken to the nearest hospital and thats where Carlisle found me. i was bitten on my left wrist due to not being able to easily move any other part of my body without pain.
Little did i know that the huge ship was doomed to hell with or without me on board.
