1600s
She was a spectacular teacher. Carlisle didn't even know there were so many things in this world worth learning. He had no idea how big the world was before he met her.
Once Bella started teaching it was like she became a completely different person. Her whole face came alive and she lit up. Despite their differences in hunting preferences he couldn't help but be attracted to her.
"Carlisle, come outside!" He heard her shout from a distance. Carlisle smiled and put down the book he was reading. As he stepped out of her house he froze. The scent of human blood was thick and he felt his throat burn. He couldn't speak from fear of losing control if he tasted the blood in the air. "How do you expect to forever abstain from human blood if you can't control your urges?" Bella asked as she held a severed, bloody finger up. A drop of crimson fell onto her hand and he wanted nothing more than to lick it off of her. "Whether you like it or not you'll eventually run across a human. Avoiding them will just delay the inevitable. If you can't control yourself than you'll eventually slip and kill one of your precious humans." Carlisle knew she was right, but didn't want to move. When Bella saw he wasn't going to move an idea came to mind. "Everyday I'll bring back a bloody finger until you can control yourself enough to take it from me. And before you even think about running away to spare those humans their fingers, if you leave I promise you I'll torture 100 humans."
Carlisle didn't want to agree to her terms, but he couldn't live with the thought of 100 humans going through the pain he knew Bella could put them through just because of him. So instead of running away he moved towards her at a gruelingly slow pace. After three steps he couldn't control himself anymore and started charging towards the blood. Once he was in arms' reach Bella easy stopped him without even having to use the hand holding the finger. He struggled against her until his senses came back.
He was ashamed at his actions. This isn't how he wanted to learn control, but he was grateful to her for trying to help him.
What do you think of Bella's methods? Harsh or realistic?
