"I don't want my relationship with Allison to affect your friendship." His arms tightened a little, and he sighed. "I don't know if it's better that way...just two people. I had Paige, and then I had Kate. And when I saw you...when I bought you, I didn't think of Isaac in that way, so I didn't think of us as...more than just you and me. I didn't think you were the first among many, or anything. I didn't plan on taking more slaves. It just...happened."
