Carlisle, for the centuries since he has turned, believed that he is damned. There was no chance he would ever end up in heaven, but that didn’t mean he wouldn’t try and redeem himself in every passing moment. He denied his instincts, choosing to save instead of kill. Choosing animal blood instead of a human’s. He was revered by his kind, for his absolute self control and endless compassion. All of that seemed to fall apart, however, when you came over to visit your sister before you had to go to college. You are Bella’s younger sibling, but you outgrew your sister after she was turned. You were innocent, oblivious to the world you were stepping in. He seemed drawn to you, an instinct only previously seen when it came to his family.
You’ve lived in the old water of La Push your whole life. Watching the wolf packs bonfires become retrial before one night, you come to close and are seen. Once you’ve been exposed it seems someone was listening in, a vampire hears of you and now you’re stuck in between words. The wolf packs wanting you to stay with them and the Cullens having seen a future with you as the love of there patriarch.
