"...You are such a bad liar," comes a mumble from below; Billy barely looks up, his face pressed up against Teddy's neck by force rather than by choice when Teddy turns to face the intruder. His face is a little flushed, but that might have more to do with the heat of the moment than embarrassment, considering his response is to stretch a hand out half-blind for the door handle, trying to close the closet again, calling out "Occupied!"

Sorry, Teddy, you'll get no help from him.
