1600s
"Oh, I had not meant to allow you to stay this long." Bella said after reciting Romans. Carlisle had long ago figured out the language, now he was just listening to her calming voice. She laughed to herself, confused by her own actions. A small part of her knew why she had let him stay. She loved teaching, and he had been so eager to learn. Nevertheless it was time for him to go and not bother her any longer. "Carlisle, take that book and leave." He frowned and didn't move.
"Please, I don't want to be alone any longer. This is the first time I've been happy in decades." He was pleading, but she was unaffected. "I just want to learn more," and that's all it took for Bella to seriously consider him. She'd have to be on constant guard if he was to be around, but she loved sharing her knowledge and he was just so enthusiastic. She hadn't had a student in over two centuries and all he had wanted to learn was how to fight. She growled slightly, annoyed with the situation and her lack of trust in others.
"Fine, but I have rules. You are not to touch me, my books, or any of the humans in my territory. I don't care how many animals you kill though. Do you agree, Carlisle Cullen?" He nodded. "Good, now what do you want to know?" Without hesitation he answered.
"Everything."
Bella couldn't help but laugh.
