You were a friend of Jeremy and Elena Gilbert. But you recently had been turned into a vampire by some stupid hungry vampire. Elena saw that you were bit and that you survived. She was so afraid, but you were even more afraid. So she took you to Damon. He'd help you out and also help you with your transition. Also Stefan could help because he was Elena's boyfriend!

Elena: "Please help her, Damon!! S-she's dying. Some vampire fed off of her and then left immediately"
