"A Bad Wish"
"You have been given detention for a reason, Mr. Ackroyd," Severus said. "You melted seven cauldrons with a foolish and dangerous prank. Something you heard about from one of your friends?"
"Yeah, but it didn't make that happen," Denny said, scuffing the floor of the dungeons with his right sneaker.
"This was a far more volatile potion than the one that Mr. Potter and Mr. Weasley destroyed in their second year, with only a third-rate firework," he said, his anger growing. "You are fortunate indeed that I happen to retain very quick reflexes, and was able to stop the explosion from furthering. Otherwise the entirety of the dungeons would have been obliterated, and all in the name of a practical joke!"
Denny pulled back a few steps, scared almost witless.
"Severus?" Mrs. Snape called, and she walked into her husband's study. "Oh, hello, Mr. Ackroyd. I heard that you nearly made me a widow."
"Did you wish to speak with me, Hermione?"
"Yes, please. It will only take a minute."
"Fine, fine. Wait here," he said, scowling at Denny, before following his wife from the room. While the young Hufflepuff waited, a small girl with curly black hair and big, dark-brown eyes walked in. Three-year-old Amalea Snape was looking for her parents, and she frowned when she saw the older boy.
"You're the one who's got detention all weekend, aren't you?" she asked. The daughter of two extremely intelligent parents, Amalea spoke well, and had a rapidly-increasing vocabulary, thanks to her voracious appetite for the written word.
"S'what if I am?" Denny said, crossing his arms. As the oldest person in the room, he was feeling tremendously empowered; a fourth year up against a toddler. He revelled in the sensation.
"Daddy wants you to be expelled," she said, taking a step forward.
Denny snorted. "And?"
"If I had a wand, I'd challenge you to a duel."
"I've got a better idea," he said. "You know that movie your mother forced us all to watch in Muggle Studies last term? How would you like to see if it's fact or fiction?"
"What do you mean?" Amalea asked, stepping back nervously. Her voice was starting to shake, and so were her hands. "What…"
"I wish the goblins would come and take you away, right now," Denny said, and he laughing evilly, trying to frighten the little girl.
Instead, he nearly wet his pants when the candles were all extinguished, and he heard the scuffling of many light feet. There was a muttered curse from the room next door, and someone cast a spell to make the lights flare up again.
"What's going on?" Hermione asked, looking around. Severus frowned at the young student.
"Why did you put the lights out?" he asked, striding over.
"I d-didn't, P-professor Snape. Honest."
"'Honestly'," the Muggle Studies professor corrected. She glanced around the room. "I'd better go and tell Amalea to wait in her room until we're done here."
"Uh…" Denny said, his gaze dropping to the floor. The Snapes closed in on him.
"What happened?" Severus asked softly, coal eyes glinting.
"Well, you see… I didn't think it'd actually work… and it probably hasn't…"
"What hasn't worked?"
"Use Legillimancy on him, Severus."
"Now you wish me to be unethical, my dear?"
"When it concerns the possible disappearance of my daughter, yes!"
"Fine," he said, and he forced Denny to look him in the eye. He muttered, "Legillimens," and saw—and heard—what had transpired. He was paler than usual when the spell ended, and he could hardly speak. Finally, he looked at the boy. "Tell Professor Dumbledore precisely what happened. Give him a Pensieve memory if you have to."
There came a knocking, and the potions master pushed the boy to the fireplace. Denny flooed to the headmaster's quarters, while Hermione went for the door.
"No!" Severus hissed, and he pulled her back. "I will deal with him. Hermione, go to our bedroom. Find my address book. Look up Sarah Williams; she's my aunt. Tell her that I'm going after Amalea. She may be able to help. She has beaten the Labyrinth before."
"The Labyrinth? Hang on. Sarah Will…"
"My father was Toby. Tobias Williams. Find my Aunt Sarah. Go!" She obediently ran out of the study, just as the door opened on its own, admitting the Goblin King.
"Good evening," he said, tilting his head. "I believe a child was wished away."
"My daughter," Severus said. "I wish to run the labyrinth to get her back. I'm aware of the dangers."
"Yes; that movie," Jareth said, tapping his ornate riding crop against his left thigh. "But the real perils are far more terrifying than any movie could possibly convey."
"The boy who wished my daughter away is too young to have known what he was really doing, while cynical enough to believe that it wouldn't work. He is of no relation to her. It was in retaliation to a punishment that I, as his teacher, was bestowing upon him."
"But he was the one who did the wishing," Jareth said. "Do you really desire to run the labyrinth?"
"Very well then." The goblin king dropped a crystal, and he and Severus vanished from the room, just as Hermione re-entered, having found the floo address. She had only ever heard of her husband's 'crazy Aunt Sarah'. Now she was about to find out why she had isolated herself from the rest of the world so many decades ago.
"House of Sarah Williams," she said, and the fireplace swallowed her up.
The fireplace at the other end spewed her onto the floor. She dragged herself to her feet, shaking off the soot as best she could.
"Who's there?" a voice, hoarse from disuse, whispered.
"My name is Hermione Snape," she said, approaching a darkened corner. "My husband is Severus Snape, son of Tobias… well, as I've learned this evening, Tobias Williams."
"Toby." A lamp was turned up, and Hermione gasped. Seated before her was a young woman, surely no older than Denny, with long brown hair and a haunted expression.
"Who are you?"
"I… I am Sarah Williams."
This is the first chapter of my first cross-over fic. Hurrah! I came up with this idea ages ago, and took the opportunity of writing this as a chapter in "DVD Delights". I hope you all enjoy this story, and look at the banners on Deviantart. I would have posted this yesterday, only ffnet was being silly.
