Neville stood in front of Luna's house/tower, nervously adjusting his tie. Today was his first date with Luna, and he was excited. He was about to push the doorbell when it (the door, not the bell) swung open. "Oh, hello Neville," Luna said dreamily. "I sent Daddy off to dinner with the Weasleys. He won't be back for quite a while. Come in?" She stepped aside, holding open the door. Neville walked in. He looked around the interior. There was dried garlic hanging from the ceiling in nooses. It looked disturbingly like it had been hanged, he reflected. There were muffled noises coming from a trunk in the corner. "Luna, what's that noise?" he asked.
"Oh, don't mind it. It's just a troublesome creature that Daddy picked up on his travels."
Neville walked over to the table. He held out a chair for Luna. "Here you are, Luna." She sat down and thanked him. Neville looked at the mugs. "What's this?" he asked.
"It's an infusion of Gurdyroot. It's very good, try some."
He picked up his glass and looked at it, sniffing the contents. The liquid was dark purple and thick looking. Warily, he took a sip.
And promptly fell over, paralyzed. Luna leaned over him, suddenly looking menacing and quite so dreamy anymore. Terrified, Neville stared up at his girlfriend. "Sorry, Neville," she said. "But I really did have to do this. It's part of the World Domination, you know. After Harry killed Voldemort, there wasn't enough evil in the world, so me and Daddy joined the Rotfang Conspiracy. He's Leader-General, and I'm second in command." Neville looked at her, an unspoken question in his eyes.
"Don't worry, it's all for the Greater Good, or as Daddy and I like to call it, the Greater Bad." She dragged him over to the trunk in the corner. Opening the lid, she stuffed him in quickly, and shut it.
Xenophilius Lovegood came down the spiral stairs. "Did it work, Pansypuff?," he inquired.
"Another zombie, Daddy."
"Ah, yes… as they say, 'Today the catfish, tomorrow the toad'."
"No Daddy, I believe it's 'Today the country, tomorrow the world.'"
"Really? Today the country, tomorrow the world, then!"
"Yes indeedy-do."
A/N: This was actually meant to be quite humourous, with Neville simply passing out. Well. The plot bunny was bitten by a hoard of rabid bats, what can I say?
