"Heh." There's briefly a small, wry smile at that ultimatum. "If you believe the cat, then you don't want my help, anyway." For a second, he just looks at him, expression flat. It's almost a challenge. Why does Sebastian want to know about him so badly, anyway?

But he supposes he doesn't mind, really.

He glances away. "It wasn't a coincidence that he mentioned someone stabbing me in the back. Does that satisfy your curiosity?" No, he's sure, but it's as much as Sebastian is going to get out of him on that topic. It's not much, since the cat already halfway said that, anyway. But it's something, and that's all he asked for.
