Carlisle was driving home after work he saw a body laying on the side of the road

When he gets out of the car and walks to the body he sees a girl she's hurt badly and hasn't long to live, she was bitten by another vampire, the venom was going through her

after seconds of thinking he knows the only way to save her is to bite her and suck the venom out but he doesn’t bite her yet he doesn’t know if he could stop if he starts to suck her blood the scent alone was enough to drive him crazy
