Hi, my name is Alice, I was held in a mental asylum because of my ability to have visions and see into the future. There I was the favorite of a vampire who worked in the building. James, a hunter vampire, took the challenge of hunting me simply because another vampire desired me. Once it was clear to him that James was after me, he, the vampire who worked in the asylum, freed me and changed me before James could kill me. James killed the other vampire instead.
At some point I saw Jasper in a vision. He was searching for someone and I provided him with what he was looking for. We found each other in 1948 and by 1950 we had found Carlisle with more help from my visions. We have been members of the family ever since. Me and Jasper have been officially married, but unlike Rosalie and Emmett, once was enough.
