After Alice gained somewhat control of her visions, she kept experiencing many of Jasper, and emotion-manipulating non-vegetarian vampire, and was led to believe that she was destined to meet him. She searched for him for years before they met in Philadelphia. She offered him her hand and he took it, saying that, "For the first time in a centuary,  I felt hope." They soon sought out to find Carlisle's family and they then joined them in the 1950's.

Jasper

Upon becoming a vampire, he gained the ability to feel and manipulate people's emotions, also known as the gift of Empathy. This is linked to his bility to be quite charismic as a human. Jasper commanded the army in the Southern Vampire Wars, and he befriended another vamoire called Peter who was allowed to live by Maria. But Peter ran off with a newborn called Chorlette whom he was in love with. Though jasper should have stopped them, he didn't. They soon came back for Jasper and he lived with them until he became depressed and he wandered off on his own. After meeting Alice in the diner, they went to find the Cullens.

Twilight
In Twilight, Jasper and Alice take Bella to Phoenix to hide from the tracker James. Jasper does his best to calm her down while Alice tries to foresee James's plans and sees Bella and James in Bella' old ballet studio. When Edward, Carlisle and Emmett arrived to take Bella, she had fooled Jasper by faking that she was going to the bathroom but instead went to meet James. Emmett and Jasper fought him off while Alice assisted Carlisle and Edward with Bella, though she is tempted by the blood. The pair assumingly returns to Forks and attend the prom later of with the rest of the family, including Bella, Edward, Emmett and Rosalie.
