You were a Winchester. Sam's twin sister to be exact. Sam and Dean were happy when you decided you wanted to go to college and become an FBI agent. So here you were, working at the BAU, dating Spencer Reid the designated genus. "Everyone to the briefing room!" Hotch called out. You got up from your desk and walked into the room, hand in hand with Spencer.

"Guys this one's a doozie. Three people were killed in Bakersfield, California. The local P.D. found traces of sulfur near the victims." You could feel the color drain out of your face.

"What were the causes of the deaths?" JJ asked.

"Blunt force head trauma." You said looking at the case file. You could tell it was a demon, how you were going to exorcize it and not be questioned by your team, you had no idea. Your phone rang, you picked it up and saw the caller was Dean. "Guys give me a minute." You said getting up and exiting the room. "Hey Dean, what do I owe the pleasure?"

"Hi (Y/N), any Supernatural cases?"

"Yeah, we just got one, I'm thinking it's a demon. Do you think you could come and help?"

"Yeah, we're out of hunts at the moment, where is it?"

"Bakersfield, California. I'll introduce you to the team if you want."

"Sure! Sammy misses you by the way."

"Tell him I said hi, and can't wait to see my twin. Bye Dean!"

"I will, and bye!" Dean said hanging up. You smiled and walked back into the round table room.

"Sorry! It was my brother," You said apologizing.

"No worries," Penelope said. "You can get caught up on the plane."

"Wheels up in thirty," Hotch said getting up and leaving the table. You stood up and walked to your desk, pulling out your copy of dad's journal. You flipped through the pages, looking until you found the exorcism chant. You quickly went over it, translating the Latin in your head.

"Whatcha got there?" Spencer asked leaning over your shoulder. You snapped the book shut in surprise.

"Don't scare me like that, and it's nothing."

"Mm-k, you gonna grab your go bag?"

"Yeah," you said grabbing the bag off your desk and grabbing Reid's hand leading him off to the elevator. Once you boarded the plane you sat down next to your boyfriend and looked through the file. Everyone else was already on the plane so it started taking off.

"Hello, my furry friends!" Garcia said appearing on the screen.

"Hey, Penelope!" You said waving.

"So the three victims just turned to four, Missy Link was just found dead in her home, traces of sulfur near her body, blood pouring out of her mouth and eyes, and no signs of forced entry. The victim must of let the attacker in." You made a mental note, the victims were possessed and then killed by the demon.

"Do you think he had some sort of ruse?" Prentiss asked.

"Like a broken down car or dying dog or something?" You asked

"Dying dog?" JJ asked confused at your example, you just shrugged.

"Possible, we've got to hit the ground running, (L/N) and Reid will go to the M.E., Rossi and Morgan go to the newest crime scene and JJ and Prentiss will go to the third crime scene. We land in an hour." Hotch stated as Garcia disappeared off the screen. Once the plane landed you and Reid made your way to the M.E. Once you got there the guy in front said there were already two FBI agents there, you smiled knowingly and just said that you knew and needed to confide in them with something.

"You just lied to save people who shouldn't be here," Reid whispered into your ear.

"I know! Don't worry I know them." You responded skipping down the hallway, excited to see your identical twin. You Kicked through the door announcing your presence. You saw your two brothers and turn towards the door, ready to make an escape. "Sam, Dean," You addressed smiling madly.

"(N/N)!!" You heard Sam yell as he came running and scooping you up in a hug. "I haven't seen you in three years." He exclaimed putting you down. You could hear your boyfriend clear his thought.

"OH! yeah, Spencer, this is Dean and Sam. My brothers." You said pointing to them. "Dean, Sam, this is my boyfriend Spencer."

"Nice to meet you," Dean said holding out his hand, Spencer looked at the hand then back at you.

"Spence here is a germaphobe, so no handshakes." You explained

"Why are you two here?" Spencer asked.

"We... um... (N/N) you explain."

"Well, you'll think we're totally insane but my family hunts the Supernatural." You said trying to explain

"Is that why you had the exorcism book before? Latin, not one of the languages I know." He said

"Right you have an eidetic memory, and yes that's why. It's what I did before I came into the FBI. We're not dealing with a human serial killer here. And why are you taking this so well?

"It'll catch up to me later. So what are we dealing with?"

"(Y/N) thinks it's a demon, and we have to agree with her. The bodies show sighs of possession. And the sulfur proves our theory." Dean said.

"So now, we just have to find a way to trap the demon and exorcise it." Sam said.

~~~~~Time skip to that night in the hotel~~~~~

Spencer got off the phone. "Derek said that he needed us in his room for something. He sounded a bit off." You grabbed the copy of your dads journal, a bottle of holy water and opened the door walking down the hallway to Morgans room. Once you opened the door you were met with a punch to the stomach. You looked up at Morgan, his eyes were black pits, he had been possessed. You uncapped the bottle and threw some of it on him. His torso burned and he stumbled to the ground. Spencer held down his arms as you started the exorcism.

"Exorcizamus te, omnis immundus spiritus, omnis satanica potestas, omnis incursio infernalis adversarii,-" you got cut off as Morgan threw Spencer off of him and threw you into the wall. You splashed some more holy water on him, he stumbled back. "omnis legio, omnis congregatio et secta diabolica.-" You got cut off yet again as the door burst open reveling your two brothers. They immediately rushed Derek helping Reid hold him down. "Ergo, omnis legio diabolica, adiuramus te...cessa decipere humanas creaturas, eisque æternæ perditionìs venenum propinare...Vade, satana, inventor et magister omnis fallaciæ, hostis humanæ salutis...Humiliare sub potenti manu Dei; contremisce et effuge, invocato a nobis sancto et terribili nomine...quem inferi tremunt...Ab insidiis diaboli, libera nos, Domine. Ut Ecclesiam tuam secura tibi facias libertate servire, te rogamus, audi nos." You finished and black smoke came out of the dark mans mouth. You stumbled to your feet but fell immediately. Spencer rushed to your side and helped you out.

"You ok?" He asked, you winced as you put pressure on your ankle.

"I think I broke my ankle." You winced.

"Glad we got here in time? And why is he so strong? It's like fighting the Incredible Hulk." Dean said

"I'm pretty sure he is part hulk," you laughed

"Well, we've got to get going (N/N)." Sam said sadly

"I guess you do moose," you said smirking

"We'll miss you, you better invite us to the wedding," Dean joked. You and Spencer flushed bright red.

"Sure, bye guys!" You said giving them a side hug, due to Spencer still propping you up. They left the room waving. You heard Morgan groan from the floor.

"What happened?" He asked

"Ummm...." you said.
