"Once you're out of my hands, what should I care?" replied Stephen, almost airily. "They can do whatever they like to you for all I care, but what matters is that you get to them. But it matters to me that I see you get delivered to your proper justice." This was all a lie that Stephen was making up as he was going along, and he knew it. "Or I just want to spite you, because you'd want to die, wouldn't you?"
Stephen stepped over to put Matthew's wand in his Mokeskin pouch. The wine could stay, it would be evidence that Matthew was gone. Maybe it would cause a panic, which would be interesting. He grabbed the bag. "Yeah, and you wouldn't want that happening, would you? So face it, you've got a few options. You can stay, and when I tell your mates what you've been up to, you can just be on the run until they torture and kill you, or I can take you back to mine and you'll just be there until I can find something useful to put you to. Which'll it be?"
Sighing when Matthew mentioned the possibility of Stephen killing him here, he said, "And what makes you think you deserve that?"
