Bill pointedly ignored that glance toward the floor, quietly convincing himself that it was perfectly fine to sleep on the bathroom floor. He'd slept on worse surfaces in his life. At least he knew (mostly because his mother had been over) that his bathroom floor was clean. Maybe he'd ask Ginny to help get everything else cleaned up. Otherwise he'd have to deal with his mother or Kingsley cleaning. Not that Kingsley ever seemed to mind cleaning. He quietly drank the potion he was given, resting back against the cabinet for a moment as he let it sink in.
"Thanks," he said quietly after a moment. "For not...being Mum for a moment. I just..." He peered at his fingers. "Can't sleep. Don't want to be dependent on potions just so I can sleep without nightmares. Firewhiskey's cheaper anyway. It dulls everything...except cutting your hand on glass. Sort of does nothing for that."
