"Not right away," he says thoughtfully. "We'll keep it in the safe for now. I won't use it."

And then, in a few months, he'll find a way to get rid of it. The weapon will never show up as a possible connection to this crime and even if it does, it will never be connected back to either of them. For now, he returns the gun to his holster, then goes back to the main room briefly to collect the pieces of the stun grenade he'd tossed in earlier. He doesn't bother with the glass from the broken window. The police will assume it's vandalism.

"You can go," he says when he returns to Karen and the body. "That way you can build yourself an honest alibi." He doesn't believe it will come to that and he doesn't really expect her to go, but he wants to know she has the option. He'll do anything to keep her from suffering in any way.
