Two young men, both in their late teens, appeared soundlessly in front of a rundown shack on the outskirts of London. Both wrinkled their noses in distaste, only for their expressions of disgust to be traded for wide, pleased smiles when a female's voice, saturated with amusement, said,
"Don't turn your noses up at my home, Messers. I-live-in-luxury."
Both turned to see a beautiful red-haired young woman in her late teens grinning at them, her hazel eyes flashing with amusement. The younger male launched himself at her, pulling her into a tight embrace, garnering laughter from the other two.
"Kitty!"
"Kitty" grinned at the boy, returning the hug.
"It's good to see you too, brother mine. Now, what prompted this visit? You two never come see me during the summer hols." She pointed out, causing the two boys to look sheepish. Then the elder of the two grinned roguishly, reminding his companions painfully of his father.
"I've got you two transferred into my custody by order of the Minister for Magic. And I'm legal in both worlds now, so those bastards have no authority over any of us." He informed them smugly, his grin looking almost painful now. "Kitty's" eyes widened.
"You mean we can leave?" she asked hopefully. His grin becoming a sad smile, he nodded – only to laugh when he suddenly found his arms full with two excited, abused teenagers.
"Yep." He answered, popping the 'p'. "Go pack your bags, Katalina, because we leave in two hours."
Squealing excitedly, she ran to do as she was told. She spun on her heel, a questioning look on her face.
"Ethan?"
The man smiled at her fondly.
"Yes, Kitten?"
"Where are we going?"
Ethan Black smirked.
"Well, Kitten, we're going to live on a Hellmouth."
Both teens stared at him in disbelief. Had their cousin finally gone mad?
Across the pond in Sunnydale, California, Rupert Giles informed the current Slayer that they were getting three very special new inhabitants.
