[tw: violence and graphic]

"What to do next, maybe a snap of the neck?" His distortion sounded. He showed a toothy grin as her blood traveled down his arm. His eyes kept that soulless black. Catherine stared at those eyes trying to see any familiarity in them, and there was nothing.

He closed his eyes and sniffed the air. Luckily Catherine pulled herself up enough so she could breathe a bit. But…how long can she last. Vincent's nose eventually went to his arm, to her blood, and he licked it off. Catherine averted her glance in disgust. He started purring, which sounded like a chuckle, and that grin wouldn't leave his face.

-shunk-

Both of their attention was pulled to his shoulder, to find a tranq dart. The tranq dart did nothing to the imposter, but it stopped the flow of adrenaline. Vincent slowly morphed back, claws exiting Catherine's neck, beastly abilities going away. Only the core remained, the beast was gone.

"Drop her!" JT shouted, trying to get to his feet with the tranq gun aimed at Vincent, or whatever this thing is. Why didn't the tranq knock him out? This Vincent looked at JT with a straight face. It was like he didn't know how to react to JT to being awake again. Eventually Vincent showed annoyance.

"Oh look who awoke to play again. I'm glad in a way, because this other toy was straining me too much. Vincent was really struggling to make me stop. But then you had to take the excitement away with this dart." He stated irritably. Vincent let go of Catherine to pull the dart out. Catherine fell to the ground coughing, breathing in all she could. She managed to get grab her pistol and Vincent was making his move to JT.

"Vincent, NO! Fight whatever is in you, don't stop fighting it." Catherine managed to yell out, and the pain resonated in her throat. Vincent stopped walking toward JT, it looked like a spasm happened throughout Vincent's body. Vincent fell to the ground landing on his hands. His body was convulsing, he was heaving and coughing. Catherine worried, rushed to her feet and ran to Vincent. JT shocked, rushed over as well. Catherine bent down to his level.

"What in the hell is going on?! Vincent, you okay big guy?" JT said in a panicky tone. As Catherine looked at his face black smoke was slowly flowing out of his nose and mouth.

"Get out of me.." Vincent coughed. "I won't let you hurt them anymore, Skuld." Vincent put so much effort in those words, he was fighting to speak them. Vincent then snickered.

"I admire your vigor, but I'm not letting go easily." Vincent said. "You might win after all." Now Vincent wouldn't stop chuckling. The laughter soon turned into coughs. Each cough brought out black smoke. It got to the point where Vincent was dry heaving this smoke out. Catherine didn't even know what to do, neither did JT. The smoke then moved back into Vincent. Vincent fist clenched, his body started to convulse again.

"Vincent?!" Catherine exclaimed she grabbed his hand. The convulsing stopped, he breathed in deeply. He looked at her hand; the cuts sent a shiver down his spine. He did that to her. He then put an effort to look in her eyes. Catherine could see the guilt in his eyes, and it was his eyes. No hint of that blackness. She watched as his eyes moved to her neck. He expression turned even sadder.

"Catherine, I'm so sorry," Vincent managed, "You need to get out of here so he doesn't hurt you again…you too JT." He looked to JT, then back to the floor, struggling again. Catherine then took his face and made him look at her, she could see blackness spreading in his eyes, and his effort to hold it back.

"Vincent, we'll never leave you. We work better when we are together. We'll beat this thing back together." She told him. "Yea Vincent, why would we leave when you need us the most?" JT added in. Vincent slowly nodded. Since he was coughing this thing up, Catherine just patted his back, to try to help and to show that she was there. JT was there as support. They had no idea what they were facing so what could they do..Vincent was silent for a moment and then he started to cough again. He was really straining to get this thing out. After a while of hacking and coughing, his body started to writhe painfully. With that pain, he started to yell. This shook Catherine and JT..is he okay? Catherine gripped on to his hand tighter. It was the only thing she could think to do.

"You can do it Vincent. You can beat back the beast; you can sure as hell beat back whatever this is!" Catherine spoke with determination. Vincent breathed in sharply, he was shaking. He strained to hold it in, but Vincent yelled in pain again. As he yelled again a trail of that black smoke tunneled out of his mouth and flew to the ventilation. JT followed it with his eyes and he saw it leave the building and fly away. Vincent almost collapsed but Catherine managed to keep him up. Vincent was breathing heavily, struggling to hold his ground.

"C'mon let's get you to the couch, you can rest there." JT said as he walked to him and put him on his shoulder to support him, Catherine supported his other side. Steadily they made it to the couch and Vincent collapsed on the couch and sat there catching his breath. Catherine then felt the full extent of her wounds and sat down herself. She touched the wounds on her neck and let out a pained sigh. Curiosity was killing JT, although he was hurt he couldn't wrap his head around what happened.

"What was that Vincent? I just saw a column of smoke escape your mouth…and that smoke looked like it had a mind of its own. What kind of sickness has that smoke and causes a personality change?" JT questioned. Vincent swallowed hard. He held the answer but hardly believed it himself, he shook his head. It wasn't possible..this had to be a dream. "Vincent..?" Catherine asked. Vincent looked at her again seeing her injuries on her hand, shoulder, and neck. He did those, it send shivers through out his body. Then looking at JT and seeing all those scrapes and bruises made him feel even worse. Vincent dropped his head into his hands.

"I…I'm so sorry. I couldn't control myself." He stammered. "I can hardly believe it myself..It doesn't make any sense." He lifted his head and looked at the scene before himself. "And it looks like this is actually not my imagination. That thing inside me..was a demon. I was possessed."

"Wait, we are talking like a demon, like the Exorcist?" JT exclaimed. It sounded so weird to all their ears. Vincent sighed, "Yes, I still don't believe it. Among the things this Skuld said to me was that he was a demon, looking for some fun." Just when they all believed their lives couldn't get any weirder, this supernatural event happened.

[A/N: The demon's name, Skuld, means guilt. That gives a hint why the demon was attracted to Vincent.]
