Hi. I do not own any of the characters in this story- in all chapters. This is a crossover between The Vampire Diaries and Supernatural. This story takes place after Supernatural series 5 episode 19, and after The Vampire Diaries series 2 episode 9. And Matt knows about the Vampire- Witch- Werewolf thing aswell for some reason. I'm open to suggestions about couples! Enjoy!

Chapter One

Something weird is going on, Elena thought. She was sitting in her bedroom, watching the raindrops fall outside, and the thunder boom, and the lightning strike. She picked up her phone and called Stefan.

"Stefan?" She said when he picked up.

"Elena! What's wrong?" Said Stefan. Elena could hear the whistling wind and thunder coming from the phone.

"Nothing... Stefan, will you do something for me?"

"Anything," Stefan said simply.

"I want you to bring Bonnie, Caroline, Matt, Damon, Rose, and yourself to my house. And hurry!" Elena hung up the phone and sighed.

…...

Katherine was so hungry.

Trapped in a tomb with no blood was really taking its toll on her. She only wished she could have said good bye to one person before she was shut in this damn tomb...

The only person that mattered...

Katherine looked down at the diary in her hands. There was one line of writing on the page.

'Dear Diary,' it said, 'I miss him.'

"Elena!" Bonnie said as she rushed into Elena's room, accompanied by Caroline, Stefan, Damon, and Matt.

"Bonnie? What's wrong?"

"Something bad is happening. It's... It's like The Apocalypse or something."

"So not Katherine?" Jeremy asked, coming into the room and putting his arms around Bonnie possessively.

"I think it's even more powerful than Katherine..."

"So what could it be?" Caroline asked. Suddenly a strike of lightning burst from the black lurking clouds.

"I just don't know," Bonnie said.

…...

"So, it's a Vampire we're dealing with?" Dean said, loading his gun with wooden bullets.

"I think so, Dean. I mean, five bodies drained of blood already. Mysterious attacks on a girl named Vickie Bennett. If it's not a Vampire, what the hell is it?" Sam said, eyes on his laptop.

"An animal?"

"Yeah right."

"Well then," Dean said, "Where is this place?"

"It's a little town in Virginia," Sam said, "Mystic Falls."

"Should we take Bobby?"

"No. Bobby's on a job in San Francisco- taking care of demons, I think."

"What about Castiel?"

"What about me?" Castiel said, appearing in the grubby hotel room from nowhere.

"Are you coming with us? To Mystic Falls?" Sam said.

"Why?"

"We're going to kill some Vampires."

"I'd rather not-"

"Great," Dean said, "Let's go."

"Where are you!" Katherine screamed inside the tomb. She was screaming... Searching... For him. He said if she called, he would come. Could he even hear her?

"Please!" She screamed, as her own screams echoed off the stone walls of her prison.

"Did you hear that?" Damon said back in Elena's room.

"Hear what?" Matt asked.

"Stefan, Caroline, listen," Damon said, ignoring Matt as usual.

Matt sighed.

"Hear that?" Damon said.

"It's Katherine!" Stefan said.

"Who's she calling for?" Damon said.

"Who's Castiel?" Caroline asked.

…...

"I'm on the Highway To Hell !" Dean sang as his Chevy Impala cruised along the road to Mystic Falls.

"Dean- there's a small town on the way to Mystic Falls we should stop at." Sam said.

"Where?" Dean said, turning down the music.

"Called Comet Church- there have been Vampire attacks there, too."

"The Vampire attacks are more severe in Mystic Falls," Castiel said.

"Still, Cass-" Sam turned around to look at Castiel who was no longer there.

"He's gotta stop doing that!" Dean said.

…...

"Katherine? What should we do?" Bonnie said.

"Leave her to rot," Damon said.

"Who's this Castiel guy?" Matt said.

"I don't know..." Stefan said. "Damon, did Katherine ever mention a Castiel before?"

"Never heard of him," Damon said. "Rose? Have you?"

"Yes, once. When I captured her, she kept muttering, "Castiel, my Angel Castiel!"

"Oooh, an Angel," Damon said mockingly.

"Shut up, Damon," Elena said.

"I don't think I will," Damon said.

"Damon," Bonnie said warningly.

"You are Princess Elena. And you're getting your little pet witch to fight your batt-" Suddenly Damon fell to the ground, clutching his head as Bonnie stared at him.

"Shut up, Damon," She said.

Damon just grunted as he stood up again. Rose bit her lip as she watched Damon- wrong as it was, she cared for him. A lot.

"Anyway, Elena, why are we here?" Matt said.

"I need Bonnie's help with something. And if I'm right, I'll need you all here." Elena said.

"What do you need?" Bonnie asked, stepping forward.

"I need you to go into a trance for me; see who or what is creating the storm."

"That's a good idea," Rose said, "This is no normal storm." Everyone turned to look outside of Elena's window.

"I need a candle," Bonnie said simply.

…...

Castiel landed in the middle of a cemetery. He looked around- where was he? He hadn't intended to come here.

"Castiel!" He heard someone scream. He knew who it was instantly.

"Katherine!" He yelled. There was a pause.

"Castiel?"

"Katherine!" Castiel zapped to where the voice was coming from.

"Castiel," Katherine breathed when he appeared.

"Katherine," He said softly as he walked quickly towards her.

"Don't! Stop!" She cried. Castiel stopped.

"Katherine? What's wrong?"

"There's a- a barrier-" Katherine said through tears.

"A barrier? What?"

"I can't- can't get out- you can't get in- a- a- barrier at the entrance of the tomb-"

"What do you mean?" Castiel said. He walked towards the entrance to the tomb and put his hands on the invisible barrier. "Who did this?"

"A Witch," Katherine said, over her crying phase.

"And you can't get out? And I can't get in?"

"Not until you find the Witch who did this."

"Who is it?"

"Bonnie Bennett."

"A Bennett Witch?"

"Yes- so be careful."

"Why did she put you in here?"

"That doesn't really matter right now does it?"

"No- did you call me here?"

"I was screaming your name."

"No, no, it was a magical pull."

"Then it wasn't me."

"I have to go now."

"No, Castiel, don't-"

"I have to go. Where are we?"

"Mystic Falls cemetery."

"Goodbye, Kathy," Castiel said before dissapearing.

"Wait- No- Castiel!" Katherine shouted.

"He should get a cell phone," Sam said.

"Who should?" Castiel said, reappearing in the back of the car.

"You should! Where do you keep going?"

"I went to Mystic Falls."

"Why?" Dean said through a mouthfull of beefburger.

"It wasn't intentional."

"What do you mean? You were pulled there?" Sam said.

"By a stronger supernatural force, yes."

"What "force"?"

"I don't know."

"We're about to find out," Dean said as the Chevy Impala sped past a sign that said, "Mystic Falls. Here since 1831."
