Authors Note: Let's face it. I'm the worst. I never update, and I have no idea what I'm doing anymore.

Emily blinked in shock as she took in the scene before her. When the man in the trench coat had appeared, she'd gone tumbling down to the ground. She found her way to her feet now. She wiped the sweat on her hands onto her pants and took a deep breath.

The rest of her team seemed just as confused as she was. Even Reid was speechless, his mouth opening and closing, reminding her much of a fish.

"Are you okay?" JJ asked, trying to steady herself. Teleportation was still not her favourite way to travel. There was a slight turn in her stomach and the need to empty it. Pursing her lips together, she attempted to keep her stomach contents where they were.

"JJ?"

The blonde stood before her, with that man in the trench coat and Sam Winchester? What was going on?

For some reason, once the bright light had appeared, Haley had seemingly disappeared for the time being. It was just them. The BAU, an angel, and a wanted fugitive.

Despite everything they'd seen, Derek reached for his weapon. Hotch put his hand on Derek's arm and shook his head. Whatever was going on, it put everything into question.

"That was..." Reid's voice broke off. "A ghost?"

Sam nodded, "Yeah, I'd say so."

The agents barely reacted. One of the most wanted men in America was telling them that they'd encountered a ghost, and not one of them thought he was crazy anymore. Parts of their minds screamed that he was. They didn't want to believe that the things that went bump in the night were real, but seeing was believing, and as hard as they tried... They couldn't deny what they'd seen.

"And you're..." Reid looked at the man in the trench coat.

"Castiel." The voice was gruff. "I'm an Angel of the Lord."

"Right," Emily said as she reached for her head. Dizziness overwhelmed her, and she forced another deep breath.

"I'm so glad you're okay," Garcia said, finally finding her voice as she threw her arms around JJ.

"I'm glad you're all okay." JJ looked pointedly at Hotch. He nodded at her. He understood. Or he thought he did. JJ had known all along. He remembered once asking her, when she'd been sorting through case files, what a specific pile was. They were the unexplained ones. Bodies drained of blood. Murders inside a locked home with no other way in. They were the ones she called the Winchesters for, and it was why, the killings seemingly stopped even though his team had never gone out to solve them. So many different things began to make sense to him. She'd kept it from him. He couldn't blame her. He wouldn't have believed her, but still, a part of him felt betrayed.

"Alright, why don't you tell me what's going on?" he demanded, staring at Sam.

"Dean and I came here to investigate killings. We came to the conclusion it was a ghost, and with some research, determined which ghost it was." It was short and to the point, but it didn't leave Hotch feeling much better.

"My ex-wife is the one killing people?"

"Always husbands whose job takes them away from their family," JJ told him, a soft sadness to her voice.

"Oh." There wasn't much else he could say. He saw the sympathetic look from his friend Dave. Words failed David Rossi at that moment. He'd seen his first ghost, but a part of him couldn't believe it. Was it all some optical illusion? Was it an illusion when Emily had been elevated? When Hotch had been thrown across the room? When the man int he trench coat, Castiel, had appeared out of nowhere with one of their team members and a wanted fugitive in tow?

"Let me get this straight. You and your brother... hunt ghosts?" Derek asked, his mind still reeling as he tried to make sense of it all.

"Ghosts. Demons. Werewolves. Vampires." Sam examined the surroundings closely. The ghost had disappeared, but that didn't mean she was gone and they were still in danger.

"Dean's body was dug up in St. Louis. Can you explain that?" Reid asked, his mind wandering to the books he hadn't got to finish. In that one, there'd been a...

"Shapeshifter," Sam said reaching to unzip his bag. "We don't have time for specifics. We've got to be prepared."

Reid's mind was overwhelmed. His thoughts were going so fast, even he couldn't keep up. The books were true. The world of the supernatural was true and it was so much more for him to learn. To understand. Everything he'd thought he'd known was brought into question. Was Castiel really an Angel? His mind strayed to the Tobias. He had been crazy, hadn't he?

"So," Emily said, a slight amusement to her voice at the whole situation. "How do we fight a ghost?"

A part of her couldn't even be shocked as Sam pulled out salt from his bag. "We'll salt the doors in this room, and the windows. She won't be able to cross through."

Now, Dave had opened his mind to a lot of things, but this sounded ridiculous.

"You brought guns?" he said suspiciously as Sam pulled a couple guns out of the duffel.

"The bullets just go right through," Emily said softly, still in shock at the whole thing. She'd tried to shoot the ghost. She'd tried to shoot Haley.

"Yes they do," Sam admitted, "But these are pellets filled with rock salt. They'll hurt the ghost."

It sounded... Insane. It sounded more insane than "ghosts are real."

"It's not unheard of," Reid interjected, seeing the disbelief on his team's faces. "There's a lot of lore that suggests salt. I just never believed it before and thought of them all as stories..."

"Salt and irons for ghosts," Sam said putting some fire irons on the table. "Silver for werewolves and shapeshifters."

"Stakes for vampires?" Rossi asked. Though he'd known what he'd seen, it still came out sounding a bit sarcastic.

"Actually, you behead vampires. Most of the vampire lore is wrong," Sam said, not paying much attention to the sarcasm in the agent's tone. "Dead mans blood can slow them down though."

"I must leave," Castiel said suddenly, his head tilted slightly to the side. "I'm needed elsewhere."

It was a strange and abrupt as he disappeared into the white light. Again. And it was almost as if he could hear something they couldn't... But neither Sam nor JJ seemed phased by it. They had begun salting the room.

Though it still seemed ridiculous to them, the rest of the team began to help. And they rushed as the room quickly dropped to an ice cold temperature. Emily was able to see her breath.

And then she saw her. Her eyes turned an angry red as she stood at the doorway, unable to enter.

Reid's eyes grew wide as she hissed, and a breeze came out of nowhere and the salt began to dissipate. She was trying to clear a path.

The loud sound of the gun caused him to jump. The ghost of the woman they'd once known as Haley, let out a wail and disappeared. He turned, expecting to see Sam standing there, but his jaw dropped when he saw it was Derek. Derek had picked up one of the rock salt filled guns, and fired.

Before he knew it, he was laughing. It was ridiculous. It was all so ridiculous. Here they were, fighting ghosts with salt and allying with a man the FBI had been trying to nail for years.

"Got any more of those?" Emily asked, gesturing to the guns both Derek and Hotch had picked up.

Author's Note: Sorry. Had to make Castiel leave. He would make it way too easy I suppose.
