Two hours later, we found ourselves sitting in Sherlock and Watson's flat at Baker Street. It was cramped and crowded with every surface littered with papers and books. Sherlock strayed into the kitchen as Sam and I sat on the couch. Cas fluttered off at the first chance he got, said he needed to be alone. Whatever that meant. He seemed distraught, maybe because I yelled at him for not telling me about Ruby. I didn't want to bother him.

"So you're saying that these demons can take people through smoke?" John eyed me warily from the nearest armchair. This whole thing seemed too much for him, he looked nervous.

"It's not really smoke, it just looks like smoke." Sam explained. "But it's black and that's where the eyes come from."

"If I believed you- which I don't by the way," Sherlock interrupted, sitting down in the armchair across from John. "Where would this thing be now? How would it be hiding?"

"That the problem." I sat up, trying to pull myself out of the sunken couch. It practically sucked me back in. "It brought us here, so obviously she has some kind of plan for us. Maybe it want's us to see something."

"She." Sherlock put his hands to his lips as if praying while looking at me intensely. It was almost as if he was mocking me. Have I mentioned how much I disliked this guy? He sent the shivers down my spine, the way he always stared at me.

"What?"

"You said she."

"I meant 'it'." I explained as Sam turned to me. He knew I was lying, but letting me stick to it for whatever reason.

"Right." He got back up, like a spring. "So this thing brought you here and now…" He paused and then clapped his hands together excitedly. John rolled his eyes from beside us, obviously seen Sherlock's charade before. These guys lived together and look awfully comfy, I'm not making any assumptions but I was convinced that John was a bottom by this point in the afternoon. "So what does it want? What is it's motive for bringing you here in the first place?"

"Something to do with Sam." I said, not wanting to wait until later to break it to him. Secrets only screwed with us. He had a right to know that it was his crazy ex-girlfriend that was killing people now.

"Finally!" He turned to me, irritated and eyebrows raised. "So who is it?"

John and Sherlock stayed eerily silent as I struggled to find an appropriate answer that would hurt him. "Cas said that it could be…Ruby."

Sam sucked in a pained breath. Visibly he changed, closing off. Sherlock noticed it and narrowed his eyes at my brother before sitting back down like a child and watching us with his hawk-like eyes.

"It could be?" Sam said through clenched teeth. "What does that mean?"

"Cas said that she got out earlier and he didn't want to tell us." I mumbled, not sure how much to spill in front of these two. Apocalyptic brother isn't usually first-date material. "I kinda yelled at him for it though."

"So, she wants me…for something." He said, turning back toward John who looked concerned.

"So this Ruby." Sherlock gestured while shutting his eyes. "Was some kind of friend? She was a demon friend but she betrayed you."

"Close, demon girlfriend." I smiled at Sherlock, happy at besting him. I still couldn't tell if he believed us or was still humoring us about the whole thing. It interested him, perhaps that was all we needed, an interesting case.

"Ah drat, close enough." Sam turned to stone beside me. I got the feeling it was still a tender subject. He didn't like admitting that he turned dark-side for her.

"So this woman wanted to get your attention." John said beside us. "Possibly in anger? She knew you were going to come after her. Maybe she wants something, like revenge or help with something."

"No that's not her game." Sam spoke up, focusing on the carpet avoiding our eyes. "She would be angry, I mean we did kind of screw her over. So it could be revenge."

"Yea, I mean, all she ever wanted was to prove that she was loyal." I said as he looked at me with hope.

"So what could this woman take from you that would prove she is loyal again?" I got the feeling that Sherlock could pretend that this was a normal case when we talked about Ruby as a woman. She wasn't a woman, she was a parasite. She took with no regard for others feelings. She screwed with my brother's head...when I wasn't around to help him and show him better.

"She lured you here, planning to take something when you got here." Sherlock thought out loud. I only half-listened, thinking. "Something that would prove that she was loyal again? Perhaps she wants to kill one of you."

"No that wouldn't do any good." Sam said, speaking up. "We are…difficult to kill. She'd want to take something that we care about, something we need."

"Ah." Sherlock looked at me, not thinking anymore. He knew what it was. It struck me at how easily he perceived the things I thought I hid so well. I hid my dependence and my fear. He could see it. But he saw more, he saw what I cared for that Ruby could take. He knew it before I did.

"Son of a bitch." I muttered before looked up at the faces. "She's got Cas."
