AN: I'm still working on Heir of Slytherin, honest. A lilplot bunny came jumping along and I just had to write this. Enjoy!
Nargles
Ron Weasley, Magical Engineer and father of one, peered into the empty pot. He was sure it had been full only that morning. "Luna! Where'd you put the Floo Powder?" he called.
"It's in the pot." A young woman with long, dirty blonde hair came into the living room, followed closely by a red-headed toddler who had grasped her Mummy's skirt and hadn't the slightest intention of letting go.
"No it isn't," Ron informed his wife, and turned said pot upside down to demonstrate his dilemma.
"Oh," Luna said, apparently surprised by this revelation, yet unperturbed nonetheless. "Perhaps it was the Nargles again." Satisfied with this explanation, she bent and scooped the small, giggling girl up in her arms and carried her back out of the room.
Utterly bemused, and sure in his knowledge that Nargles did not exist, Ron placed the empty pot back on the mantelpiece. "Loony," he muttered fondly.
