Allison paused at his words, thinking them over while looking down, and she swallowed hard. So he'd lost someone. She wasn't sure she'd ever wondered why he was up for auction at first, just assumed someone hadn't wanted him. And she certainly didn't expect him to speak so affectionately about them, either. As prejudice as she'd been taught supernaturals and those raised as slaves could be, she was always learning that her own upbringing hadn't been without it's own prejudices and assumptions.
"... I'm sorry you lost someone." She said at last, quietly, wanting to offer him that, even if it didn't seem like it meant anything. But she remembered what she'd been like back when she thought Scott had gone for good. How lost she'd been. She suddenly felt awkward, almost as though it was she who should leave the room, and not him. She heard his question though, and moved carefully, Mark still against her chest. She should put him down and stop coddling him now that he was asleep, she knew, but she found comfort in holding him. A sense of power in protecting him from anything bad that could happen. Quietly she moved over to the window, and leant with her back against the pane.
"I do care about Derek. A lot. And I don't know how much he knows that or believes that, but I do. I was given a choice. And if that choice was an easy one, I would've made it the day it was offered to me, and picked Scott. But there was even a time I wanted to just... run away. So I didn't have to pick either. So I didn't have to hurt either of them because it was the last thing I ever wanted to do." She ran a hand through her hair, and smiled weakly. "I need Derek. And I think he needs me, too." She glanced down, and moved her hand to her stomach. "... I'm giving him his family back. I wouldn't do that if he didn't matter to me so much."
