"Dean, Sam." Cas walked to the woman holding the door open for us. She was cute. She was a shy brunette who fiddled with her hair when she was nervous. "This is Molly Hooper."

"It's nice to meet you." She walked ahead of us through the white hallways, ducking her head down. "Although I wish it were on better terms."

She paused, bringing us past two swinging doors into the small morgue. "Is this more of the Leviathan?" She asked, tuck a lock of hair behind her ear.

"We don't think so, they have been gone." Same spoke up, walking to the bodies on the tables. They were still covered in white sheets. "But they seemed strange enough for us to check out."

"It is strange." She uncovered one of the bodies. "I mean, all these people, connected like this."

"Are they connected in any other ways? Like, anything similar about the deaths?" I asked her, crossing my arms as Cas stood beside me.

"Well, I had a few theories…I hope you don't mind, but I asked a colleague of mine to help with that." She said, covering the body back up.

"This guy…does he know?" I asked, looking at her.

"Oh no, no nothing of the sort." She looked up at me, pressing her lips together, "But you may find him a bit odd. But I really do believe he will help."

"I'm sure his input will be welcomed." Cas said resting a hand on her shoulder.

"Anything look weird?" I asked to Sam as he lifted up another sheet.

"Not much," He bent down to the corpse and lifted up it's lip. "Rules out vampires."

"Kinda reminds you of Croatian virus?" I asked softer, as Molly spoke to Cas.

"Kinda." He lifted up the man's hand. "But it's way more contained. The virus would have spread much faster than this."

"Yea that's what I thought." Sam put the cloth back down and we followed Molly out.

"See, I was relieved when I heard you were coming. I have never seen anything like it." She called behind to us as we followed her from the morgue.

"Like what?" Sam asked from her side.

"Well, you probably couldn't tell on the bodies, but there was a message in their skin. It very small, I had to use a magnifying glass, but it was on the same place on each victim. And the same symbol." She opened a large door and led us inside a small lab where two men were waiting.

One was small, wearing a coat and looked seemingly bored in the lab. He was short and had short blond hair. The other was tall and had thick wiry black hair. He was bent intently over a microscope at the table.

"Sherlock, John." Molly stood beside the men, "This is Cas, Dean, and Sam."

"John Watson." The shorter man came to Sam and shook his hand, then mine. He was so formal. I wondered how much they had guessed about the real case.

Sherlock made no move to get up, only sat hovering over the microscope.

"So Molly says that she asked for your help on the case?" Sam asked as Cas and I hung back.

"Well, she just mentioned it and Sherlock was on it. The symbols and the chemicals alone were enough to draw us in." John let out a small nervous laugh as Sherlock stayed silent, bent over the microscope.

"Chemicals?" I raised an eyebrow, John shot a glance at me.

"Yes." He said, blinking. "Molly didn't tell you?"

"Of course not." The statue-like Sherlock finally spoke up. "They already know what chemical it was that we found on the bodies."

His eyes looked up, not to Sam, but to me. They were bright blue, like ice. He narrowed them, looking me up and down. He seemed to be able to read me, I didn't like it.

"Tell me. What chemical did we find?" Sherlock rested his elbows looking intently at me.

"Sulfur." I said.

"Exactly!" He beamed, shooting up out of the chair. I shot a glare at Cas, I asked him if this had been demonic. It hadn't seemed demonic to me.

"How did you know that we knew?" Sam crossed to floor, standing next to me, as if to protect me. It would have been funny. Sam must have thought that this Sherlock guy was a threat if he knew so much already.

"Because your brother there lit up when John said the word 'chemicals'. His pupils dilated and he shifted his posture to an almost defensive stance. Now that was almost instinctive, so obviously, you know what the sulfur means or who it leads to. And you have known for a while." He said, walking next to Molly and John. "As to what it leads to, now that is tricky. One would suggest an animal or a serial killer with that kind of reaction. But not just any animal or serial killer, a highly deadly one. One you have been after for a very long time. One you know."

There was a pause, I could see Sam in front of me pull Ruby's knife from the back of his jeans and hold it behind his back. This man knew. He knew about us and what we were hunting. He must have been one of them. There was no other explanation.

"Tell us about the symbols." Cas shrugged it off, after the silence.

"Ah! Now that is where it gets interesting!" He walked forward to the table. "As Molly told you, they've all got the same symbol, which is a star inside of a circle."

He slid a photo across the table. Sam flipped it over, revealing the star inside of a circle in what seemed to be, behind a man's ear. His grip of the knife behind his back relaxed as he tucked it back into the waistband of his jeans.

"That's the symbol on the Colt." I said walking beside him. Cas stayed behind, eyes squinting into the fluorescent lights above us. Molly walked out, leaving just the five of us. I motioned to him.

"Dean, this may be the work of demons." He said as I pulled him aside. Sherlock spoke to Sam across the table. He kept eying us, creeping me out.

"You don't think?" I asked him sarcastically.

"No, I do think." He said, cocking his head.

"That Sherlock guy, he has to be one of them. He is practically taunting us with it." I said, trying to calm myself.

"I can see his face, Dean. He is human." Cas looked at him again and them back to me. "But I fear it may be a certain demon, one we have met before."

"Why didn't you say this earlier?" I asked, trying not to let my anger carry.

"I hoped that this was not it." He said, sighing. "I have heard rumors, of demons breaking out of hell. Certain demons getting freed."

"Well who is it? We can handle it." I said, putting a hand on his shoulder. "We have dealt with demons like this before."

I caught him glance at Sam before he said the name.

"Ruby."
