Two hours later, after using a Denny's and Sam's dying laptop, the brothers find out Del Sean had rented a motel room two streets over.

Now the two carried holy water, their guns with salt rounds and Dad's journal, creeping up to the fourth floor of the motel.

They walked cautiously over to Room 13D and Dean nodded to Sam.

Sam cocked his gun and Dean picked the lock. They opened the door slowly and slid into the dark room.

Dean stepped over to the bed, seeing how still it was. He raised the butt of his gun to hit the kid on the head.

"What the hell are you doing?" A feminine voice hissed.

"Carena?" Sam asked in a whisper.

Dean turned around to see Carena in the shadow of the open lit bathroom.

"Is that a knife?" Dean asked in a shock whisper.

"Get out!" She whispered angrily, "Before I have to kill one of you too!"

"Whoa whoa," Sam raised his hands in a surrender gesture, "Let's talk in the hall and not kill anyone ok?"

Carena glared and Dean raised an eyebrow.

Sam nudged the door back open and the three of them nodded.

Once they made their way outside the motel completely, Carena exploded.

"What the hell are you doing here? Why were you trying to kill Sean?!"

"Why are you trying to kill him?" Dean asked, "Don't tell me that knife is for making sausage and eggs in the morning cause it ain't."

"Because it's my freaking job!" She growled, "You have no idea what the hell you're in here!"

"You a hunter?" Sam asked, he had guessed it but now he knew for sure.

"That's what I'd like to think. That or some sort of vigilante hero without the cape and adoring fans," Carena snapped back, "I'm guessing your not investigators are you?"

"We're hunters," Sam explained, "Of the supernatural kind. Monsters."

"Like the one that killed my mom," Carena interrupted, "I'm guessing you know what did that don't you?"

"Ok can we start from the beginning here?! How the hell are you a hunter?" Dean asked.

"Pretty simple actually," Carena sighed angrily, "My mom didn't die in just a fire, she was murdered. Pinned on the ceiling, sliced open like a turkey! My sister saw it all. She knew. Dad didn't believe her though. We played games, hunting monsters growing up. What I didn't know was that she was trying to prepare me. Dad had enough and sent her away. Told her to stay gone if she was going to keep putting this crap in my head. He forced me to stop fighting."

Sam and Dean eyed each other, the sister behind everything? It didn't fit, but Carena continued.

"About a year and a half ago I was in a race. I saw something jump out in front of me. I spun out and saw these things. But it wasn't like I saw them there. I saw houses and more people burning. I saw one man marching with a horde of shadow monsters and about a dozen kids walking with him. Then it was over. I found myself in the hospital. Del Sean cheated on me. That's when I found out I had abilities."

"Abilities?" Sam asked earnestly, Carena was describing a vision. He didn't know how he knew but it felt the same as when he saw Jess burn.

"Ya," Carena nodded.

She twitched her finger and suddenly Dean's gun was in her hand.

Dean stepped back, whipping out his small dagger from his jacket. Sam resisted the urge to point the gun at Carena.

"I can't explain it," She said quickly, "All I know is that I had the one vision and I was sick for a week. I had stomach pains and migraines. I couldn't sleep or eat! Then it just stopped. I got out and went to see Sean. Suddenly everything was flying. The couch, his backpack, clothes, cooking stuff, blankets. I couldn't control it. I told him to leave and never come back. He freaked out and ran."

"Did your dad know?" Dean asked cautiously, his eyes trained on Carena's hands now.

"I tried to tell him," Carena's eyes leaked, she hiccuped with emotion, "I tried and he wouldn't listen! He said my brain was rattled from the accident and I was emotional over Sean! He told Sean to leave and not tell anyone what he saw. And Sean said that if my dad didn't do something he would regret it! Then my dad died on The Devil's Ex!"

Sam breathed, trying to file through everything. Then it clicked.

"You went back to fighting didn't you? The vision, you couldn't believe it was true. Some demon found out and sabotaged your dad's car. You knew your dad was too good to die like that. Something's after you, not the car people."

Carena nodded, tears falling freely.

"The smoke monsters are demons. Sam, demons are going to pour out of some hell hole and take over. One man is controlling them, one man and a bunch of kids. And I was a part of it."

"Alright, we'll handle that," Dean said, "What I want to know is what's up with the people vanishing, then weeks later showing up dead and Del Sean."

"The first demon I caught, said I'd never belong. That they had to bring me home My true home," Carena explained, "He almost killed me when..."

"When what?" Dean asked, "When your dad's ghost came?"

"Yes," Carena agreed, "My dad came and said he was sorry. That he was going to protect me now. No matter what. I only managed to cut the demon before he left the body. Then my dad vanished."

"So Jon was the demon?" Sam asked.

"No. That's the thing! The demon said he'd take me by force. That he'd make me want to join them. That's when the people went missing."

"You haven't found them?" Dean asked.

"No. There's too many people. I have no idea who's a demon," Carena sighed, "I was going after Sean because my dad told me he was possessed."

"Your dad who hated Sean?" Dean asked.

"Yes."

"Carena, the thing about spirits trapped behind is that one they have unfinished business or they're attached to an object. Like an emotional tether," Sam explained, "I'm not a hundred percent on the tether, but your dad swore to run off Sean. Sean's back. He'll want you to get rid of Sean. And it's been a year since he died. His mental state isn't strong anymore. It won't be enough to run off Sean, he'll want you to kill him."

"You don't know that!" Carena roared, "What if the demon who wants me possessed Sean? Just to mess with me?"

"You want to take that chance?" Dean asked, "There's a way to test if he's a demon. If anyone is."

"How?" Carena asked, eying him.

"Cristo."

"Excuse me?" She asked.

"It's a name. If the person's a demon, they'll flinch, the eyes will turn black, they'll be a reaction. If not, he's human," Sam explained.

"You're positive?" Carena asked.

"Completely." Dean nodded.

Carena looked down at the knife and gun in her hands. She sighed and handed Dean's gun back to him.

"Then let's see if he's an evil spawn of hell."
