John nods, dealing with the door first, simply because it's the easiest. He takes a towel from his bag, sprays a small amount of cleaner on the cloth, then runs it over the doorknob, inside and out, then proceeds to clean the exterior of the door, the wall, anywhere he thinks she might have touched. So long as her prints aren't too close to the residence, they'll be able to get away with saying she may have just been nearby.

The couch might pose a greater threat, but John also doesn't imagine it would be dusted even if someone were to trace her whereabouts to this place.

So long as he can get rid of the body and blood, they should be fine.

"I'll wait until it's dark to move her," he says after a moment. "I have supplies in the bag and in the meantime we should get as much blood out of the floor as we can." He won't tell them where he takes her. The less they know, the less they'll have to lie about.
