A/N: Hi, guys! Before we get started here, this is a continuation of last week's chapter. If you haven't read that yet, you need to. Or if you want to reread it as a refresher course, that's cool, too. But another thing about this chapter, in case you haven't picked up on the chapter titles yet, they're all song titles in one way or another. But this one is special. Because not only is it a song title, it's also the title of my favorite fic on the entire internet. The Devil in Disguise is a Destiel AU fic and it's just…Oh, it's delightful. It is smut, though, in case that's not your cup of tea. Dean's a mechanic, Cas is a priest that just moved to town. Dean in confession. It's just…ajiofdewafaeiow…It's on Tumblr somewhere. If not, there's a link to it on my Tumblr. 5/5 Would recommend. Would read again. Want it in a hard cover copy on my dresser.

Um…Ms. Olivier…Your dresser's in your closet. Wouldn't it be more appropriate to say on your nightstand?

Shut up, hypothetical assistant. Always putting things in perspective…Go on. Enjoy the resolution of the cliffhanger I left you with last week.

Finding out if my burger tasted the same coming back up as what it did going down was not in the plans for tonight. But that voice. It brought a lot of emotions up that I had been suppressing for the past year and completely caught me off guard. In those two little words, all of the walls that I thought were super reinforced came crumbling down as I buried my face in his trench coat and bawled my eyes out, "Hi, Cas…"

"Mind if I sit?" he asked.

"No," I shook my head, regaining my composure, "Go ahead."

"Thank you," Cas took the open seat next to me, "How are you?"

"Really?" I took a long, heavy drink from my tea. Not as sweet as I thought it would be. Then again, we are in Philadelphia, not the South. I grabbed half a dozen sweetener packets out of the holder. We both know you're not here to exchange pleasantries, Cas. What do you want?"

"What are you doing here?" he worried.

"Not to brag or anything," I ripped open each pink envelope one by one and poured the delightful chemicals into my tea, "But I took out a few demons today. What did you do to improve the world?"

"That's not what I mean," Cas clarified, glaring a little, "How long have you been running around with Crowley?"

"I don't know," I shrugged, "Maybe a month or so?"

"By yourself?" All of a sudden, Cas turned into the overprotective dad I never had, "Lena, I know he's helped us in the past, but you are aware that Crowley can't be trusted, I hope."

"Relax," I rolled my eyes, "I'm fine. Besides, even though it's Crowley, he wouldn't dare hurt me. This I know for a fact."

"Are you sure?" Seriously, Cas was pissed. Actually, genuinely pissed, "He's a demon, Lena. Boldface lying is in their nature. And Crowley's always had a very silver tongue."

"Don't worry, Cas," I assured, "We can trust him. Crowley's not lying to me. I'm fine."

"I hate to do this to you," Cas took my hand, immediately jerking away, "Lena, those weren't rogue demons. They were planted."

"What do you mean?" I started getting nervous.

"They were more or less target practice," he broke the news, "Crowley ordered them to come to Earth and cause mischief. Enough to make you interested, but not enough for Sam and Dean to get involved."

"No way," I shook him off, "They were on Lucifer's side and it was only a matter of time before they'd come after me."

"Did you find them, Lena?" Cas tightened his grip, "Did you personally find those demons?"

"Well," I bit my lip, "When I woke up, Crowley said there was a job if I wanted it. I haven't been actively hunting since I left. But that doesn't matter, does it? So what if I'm not the one that found us the case? What matters is that those demons are gone."

"You're a very smart girl, Lena," he hardly spoke above a whisper, "Doesn't that strike you as a little too convenient?"

I hated how much Cas was making sense. Crowley has been a tad slippery in the past, but he'd never do that kind of thing to me…Would he? No. This was just Cas trying to get in my head to make me come back to the bunker. And I sure as hell wasn't going to do that any time soon, "And? So?"

"Why?" Cas let out a heavy, exasperated sigh, "Why is it that all of the Winchesters I've ever dealt with have to be so stubborn?"

"I don't know," I played with the straw in my drink.

"It's not only the demons," he cradled my cheek in the palm of his hand, "There's something very different about you, Lena."

"It's the hair color," I figured, twisting a lock of it around my finger, "It's never been black before. I'm kind of liking it. I didn't think I would, but here we are."

"No," Cas shook his head, "It's not that."

"Think about it, Cas," I pointed out, "You haven't seen me in a year. Something about me is bound to change."

"Not your physical appearance," he studied me a little closer, "Your spiritual one. There's a very dark mark on your soul."

"That's probably from me hanging around with a demon," I guessed.

"I've only seen this once before," Cas twitched, "Lena, how are you feeling right now?"

"Like a million bucks," I reported, "Why?"

"What have you done?" Cas' eyes nearly doubled in size. That's not going to make me nervous at all. What was with him today? Cas was more restless than he usually was. He seriously needed to unclench.

"Well," I thought back, "Crowley and I got wasted in a hostess factory last night, if that's what you're talking about."

"And what were you drinking?"

"Whiskey and wine."

"Lena," Cas took in a deep breath, "You're infected."

"With…?" I hadn't been with anyone. Did I end up catching something from a toilet seat? I always thought the bathrooms in the theatre looked a little sketchy, but never disease ridden.

"The last time I saw this," he cringed, "It was in Sam. You have demon blood in your system."

"What?" I ran a quick assessment of my physical being. A little sweaty. Kind of tired. A bit light headed. Almost the same I felt this morning, but more of the beginning stages of this morning.

"Weren't you ever taught not to take candy from demons?" Cas put the back of his hand to my forehead, feeling for a fever.

"I think it's taking candy from strangers, sweetie," I corrected him, getting the feeling he might have been right.

"You're already running a slight fever," he diagnosed, "We need to get you somewhere safe, so you can detox."

"You mean somewhere like the bunker?" I assumed, getting his hands off me.

"Lena, please," Cas begged, "We can help you. Right now, we have more important things to worry about than why you left. Please come with me."

"Don't you get it, though?" I snapped, "This is the exact reason why I left. Because you and the boys don't think I can make it on my own and I couldn't stand the pity anymore."

"And look where it's gotten you," he fired back, "You're full of demon blood, Lena!"

"You're right," I sighed out, "I drank Crowley's Kool-Aid. And you know what? I like it."

"Do you realize what demon blood does to you?"

"Yeah," I kicked my feet up on the barstool next to me, "It gives me kickass superpowers. Those demons I took care of today? I didn't even lay a finger on them and all it cost me was a little nosebleed."

"It chips away at your soul until you have no humanity left. It's eternal damnation in a liquid. It will burn up your life force, Lena!"

"And who decided my humanity was so great?" my voice broke, "I was doing perfectly fine before any of the supernatural came into my life. I had a job, a mediocre apartment, a life. I got away from Sam and Dean and it's almost as if my life got better. I don't need them and they don't need me. Besides, this power trip thing is really nice."

"Lena…"

"I appreciate the sentiment, Cas," I threw some money on the counter and jumped down from my stool, "But I'm good. Really. If I become some sort of monster because of this, then so be it. This is too much fun and I don't want to give it up any time soon. So, if you'll excuse me, I'm going to go to bed and kick ass again tomorrow morning."

"Lena," Cas grabbed my arm, "Please…Don't do this."

"If you want to do me a huge favor," I kept my eyes on the floor, "Don't tell Sam and Dean where I am. Or that you even saw me. You know how much it would piss Dean off that you saw me without him or that you found me and didn't take him directly to me."

When I walked out of the diner, I felt like such a bitch for using Dean against Cas like that, but it had to be done. I knew he'd turn around and grab the boys. There's no way I'd be able to say no to them. I hope Cas had a different plan. Granted, Sam and Dean were some of the best hunters to ever exist, but when someone's as warded as I am, I'm shocked Cas could find me. He must have some contacts in Philadelphia (or Crowley opened his big mouth again) that let him know where I was. Regardless, I had to have some words with my favorite little demon…

"Your ass better not be sleeping, you son of a bitch," I threw the hotel room door open.

"I was," Crowley groaned, "Until someone came in and ruined it. What the hell, Lena?"

"You and I need to have a little chat," I kicked my boots off.

"What has your panties in a knot?" he rubbed his eyes, still half asleep.

"You do!" I snarled, "Last night, when we were in the Hostess factory."

"What about it?"

"The wine you gave me," I assumed, "What all was in it?"

"What do you mean?" Crowley looked at me like I was on drugs.

"I mean, you demon roofied me, you dick!"

"Oh," he dropped the cockiness real quick.

"Yeah, oh!" my tirade went on, "What the hell, Crowley? Why would you give me demon blood AFTER I SPECIFICALLY TOLD YOU NO?"

"I needed to settle my curiosity," Crowley brushed me off, "I didn't expect you to take to it like a duck to water, though. I don't understand why you're so mad at me."

"Because you could've asked me first!" I was ready to drive him through the wall, but that might also be the withdrawal talking.

And he couldn't help but take notice of that, "Lena…? Are you feeling ok?"

"No!" I started feeling the same way I did this morning, "I think it's wearing off…"

"Thought so."

After a little bit of soul searching and a lot of intestinal fortitude, I broke my glare with the devil I know, "Give."

"Excuse me?" Crowley perked up.

"I'm tired of feeling weak," I looked up, "Make me strong again."

"Are you sure?" Crowley grabbed a knife out of my bag.

"Are you going to juice me up with demon blood or no?" I snapped.

"It'd be my pleasure," he said with a deadly grin, "Always happy to bleed for a Winchester."

A/N: Because SOMEONE read ahead before I even wrote it, yes! Lena's hopped up on demon blood. Crowley spiked her wine and she's all full of it. Also, Cas found her! Yes, she's warded all to hell, but demons in the area will pique certain interested parties. Angels being one of them. And with Crowley and Lena disappearing at the same time, I'm sure Cas was hoping one would lead him to the other. I'd also like to point out that ending line that kind of gave me chills. We've heard that exact line once before. And I'm loving the parallel! It brings me a twisted sense of joy. Kind of like when I drop a random cliffhanger at the end of a chapter. Anyway, see you next chapter! xx
