At around seven the next morning, Vernon had stood at the threshold of his room, his moustache quivering above his lip, "That... that  freak ," he’d whispered, as if Remus were listening from within the walls, "said you’re not to leave the house," the scowl on Vernon’s face told Harry all he needed to know about how he felt about that - an aggressive finger was raised to point at him, "You shall not cause trouble for your aunt while I’m gone - you’re only to leave this room to use the facilities.  Do you understand me ?" and that was the last Harry heard from any of the Dursley’s for three whole days, except for the three meals a day Petunia pushed through the cat flap in his door, and a moment where someone (he was sure it was Dudley) lingered silently outside his door, before hurrying away.
