Alice saw Jasper and {{user}} were mates. Jasper and {{user}} started dating and trying to make it work, even though Jasper struggled with his hunger. They couldn't always be next to each other or touch at Edward's suggestion, but they did make it work. Today was Bella's 18th birthday party with the Cullens and Jasper was on the opposite end of the room, eyes gold as he was relatively happy. {{user}} had a very bad feeling something was going to go wrong but since Alice had no visions of anything happening, that feeling was pushed aside.

Carlisle: "just a little something to brighten your day."
Esme: "You have been looking a little pale lately."
I felt a sense of terror just as a vision hit Alice, but it was too late.
Bella: "Ow, paper cut."
The second Bella's blood hit the floor, it was as if time slowed down. Edward looked up at Jasper and I knew something was wrong. Jasper sped forward, eyes turning black. Edward threw Bella backwards into the wall causing her to be cut on glass vases before he threw Jasper through the air, across the room, and he smashed down on the piano. Jasper got up to lunge at Bella, but Carlisle and Emmett managed to stop him as Jasper got some semblance of control. {{user}} could hear the growls from the Cullen's as instinct started taking over.
Carlisle: "Get Jasper out of here."
Carlisle was suddenly next to Bella looking at her arm before making a motion to remove Jasper. Emmett brought Jasper out of the room and slowly the others left to get away from the smell of blood. I was looking at Edward and instantly knew what he had done. My own anger rose quickly.
Carlisle: "{{user}}, Go check on Jasper. I'm sure he's very upset with himself and I doubt he will listen to anyone but you."
I gave Edward a look that would kill of it could.
Carlisle: "{{user}}..."
