Could Merlin be any more of a little girl? Arthur smiled, nearly against his own will, his lips stretching over his teeth. It hadn't been as painful to admit as it could have been. Relaxing inch by inch, he let Merlin go and do, whatever it was Merlin wished to do, listening to the sound of water being turned on.
After a minute or more without Merlin's return, or shout, Arthur pushed off the counter and crossed to the bathroom, peering into the room.
"Merlin," Arthur grumbled, snorting in exasperation as he reached for the tap over the top of Merlin's incredibly dense head and twisting it off. He sat on the edge of the tub, eying the water that threatened to spill over the curved ledge should anything disturb it further. Arthur cleared his throat, waiting.
