Disclaimer: I (we) do not own the characters or places. All credit to the owners and creators of Supernatural and Buffy the Vampire Slayer. Riley's gone, I decided. And before we started writing thing we got a review on the story, which made both of us very happy. Thank you.
And we have some of our own characters. (To find about Amelie, go read the other authors rewrites of Supernatural episodes. I'm sorry, I've forgotten her account name.)
"You do know how to stake a vampire, right?" Buffy asked as she walked up the path to her house with Sam and Dean.
She'd left her friends behind at the Magic Box to do research on Seals while she was on patrol. She figured that if the Winchesters were used to demons and vampires, they could make themselves useful.
"Well, we don't really stake 'em," Dean replied.
"Then how do you kill them?" Buffy asked.
"Chop their heads off," Sam answered.
"You could always do that," Buffy said as she opened the front door to her house. "Dawn! I'm home."
Dean looked over at Sam. "Who's Dawn?" he mouthed.
A fourteen year old girl walked down the stairs, glaring at Buffy.
"You're late," she said.
"I know, I'm sorry. I've been kinda busy," Buffy apologised.
Dawn looked at Sam and Dean, then back at Buffy. "You got over Riley pretty quickly."
"They're going to help me on patrol tonight. Nothing else."
"And there was me thinking you just wanted me for my looks," Dean smirked.
The two sisters exchanged a look that only sisters or best friends understood, and Dawn led them through to the kitchen.
"So, Dawn, how old are you?" Sam asked, trying to make conversation.
"Fifteen. Well, almost," Dawn said.
"Willow and Tara will be here at about ten."
"Are they still researching the murders?"
"Yeah," Buffy said.
"Whilst we're waiting, can you tell us a bit more about these murders?" Dean asked.
Buffy opened cupboards pulling out what she needed to make a quick meal for Dawn.
"The first was in a cemetery on the west side of Sunnydale. I assumed it was a vampire-"
"Because that's what's normal around here," Dawn interrupted.
"But then when there were more it's kinda obvious it's not the normal, even for here."
"Sounds like the seal of the demon child to me," a voice said from behind Dean.
"Dammit Cas! Would you, would you, you know," Dean said, motioning for Cas to move out of his area.
"My apologies Dean."
"Does he do that a lot?" Buffy asked.
''More than a lot," Dean replied huffing. "So, what the hell is a demon child Cas?"
"A demon child, is one of the most powerful creatures in existence. It's power is so great that it can be hidden from an angel or a demon."
"I'm guessing that's so not good," Dawn said.
"No, it isn't," Cas said.
"Thought not," Buffy said.
"No, Dean. Do you know where Amelie's necklace is?" Cas said.
"Who?" Buffy asked.
''Uhh," Dean rubbed the back of his neck. "She's my kinda, ex,ex,ex,ex girlfriend."
"That's a lotta exs," Buffy said as she finished cooking the food for Dawn.
She glanced at the clock, checking the time.
"We've been together."
"A lot," Sam butted in .
"Sammy!" Dean replied.
"Dean you haven't answered my question. Where is her necklace?" Cas asked impatiently.
Dawn and Buffy both looked at Dean.
"For God's sake Cas, ask her yourself!" Dean shouted at Cas.
The Summers sisters turned to look at Castiel.
"Dean," Sam said "Don't take your anger out on Cas, he's done nothing wrong."
"Nothing wrong! He fricken put me in a hospital for 2 days, you know I hate hospitals!"
"I'm sorry if I caused you any trouble Dean, and you too Buffy, Dawn," Cas said before disappearing with a tear running down his face.
Buffy looked at the spot were Castiel had been, and then back at her sister.
"You'll be okay, right?" She asked.
"I'll be fine," Dawn said.
"Do your homework. Don't go out. Don't stay up too late, and Willow and Tara won't be too long."
"I can take care of myself."
"I know you can, but you don't have to," Buffy said, walking through to the living room.
Dean was scowling at Sam, who was thinking when Cas goes to Amelie and she finds out what Dean said he is gonna get smacked. He knows how protective of Cas she is.
Buffy opened the chest in the living room, pulling out a couple of stakes.
"They seriously kill vampires?" Sam asked upon seeing them.
"Yep. Stake in the heart and they're gone," Buffy said, holding one out to each of the brothers.
"Uhh, thanks," Dean said. "Sorry, it's just we were told by our Dad that you gotta chop their heads off 'cause a stake will just piss em off."
"Trust me, it kills them. They turn to dust, and then no more vamp."
"Cool. Our vamps never go all dusty," Dean replied, with all the excitement of a five year old opening presents at Christmas.
"You get used to it," Buffy said, shrugging.
She shut the chest and started walking to the door.
"See you later Dawn!"
Sam and Dean followed. Sam more than tempted to text Amelie to text Castiel.
Buffy shut the door behind them and walked down the path.
"So, we can start at any cemetery in Sunnydale."
