I stayed behind when the boys went after Jack. I wanted to help Bobby and Mary talk to the others that had come across with us and see if anybody knew anything.

The consensus was a resounding no. Nobody could think of anybody, from either universe, that would want to hurt Maggie.

There wasn't anything that any of us could do. That was what hurt the most. We couldn't bring her back. We couldn't do much besides just accept that she was dead. She may have been in more danger in the other world, but there she had been alive and here where it was supposed to be safe…

In an odd thought, I had a sudden better understanding of why Castiel had been acting the way he had. This world may not have a war going on, but it still had its dangers. It wasn't just angels and werewolves.

Jack was distraught, obviously. That's why the boys had gone after him. I couldn't blame Jack. He and Mary had promised that this world would be a safer one. I could see the same pain and guilt in Mary's eyes, no matter how hard she tried to hide it.

I could see it as Bobby finished telling Mary that same consensus I'd come to. None of us wanted to hurt Maggie. There were other monsters to worry about besides, well, monsters.

Mary's words were right. Maybe there were monsters in this world that weren't monsters.

At that word, monster, I felt a nudge in my brain.

"We killed monsters." Ketch said calmly. I couldn't see the room around us well in my mind, but I knew that tone. This wasn't a memory from when we were friends. This was one from when we wanted each other dead. "We killed vampires and witches and other creatures that would've killed humans."

"No. We didn't kill monsters." I said to him. "You became one."

"I am not a monster." He argued firmly.

"Really? Then tell me, what do you call everything you've done in your life?" We argued. I kept pushing and he kept telling me to stop talking, until finally I asked him a simple question: "What makes you so different from the monsters your supposed to hunt?"

He called me a monster too.

"I can see that this meeting was pointless." He said. "You may not be a witch anymore, but you are still a monster in your own right, and I will make sure that one day," his voice got a bit different at the end. "I will rid the world of you."

"It takes a monster to recognize another monster." I felt relaxed with those words, I remembered that clearly. I was OK with calling myself a monster, just like I felt OK with calling Ketch one too.

"You know you're going to hell, right?" I heard myself ask him. I was in pain, but that didn't seem to matter. It… it felt good to call someone else the bad guy, for a change. Someone human. "You're a monster, Ketch, and you're going to hell for it."

I snapped back to reality, and saw Jack standing in the room.

"Jack!" Mary exclaimed. It wasn't necessarily a happy exclamation, and I could see why.

Jack wasn't alone.

"Hey." Lucifer offered a small wave to us. I felt an odd shiver run down the back of my spine.

That's the monster, there. I couldn't feel a memory with that, but I didn't need one. It was a gut feeling. What my mind didn't remember, the rest of me did. Don't trust him.

There was another thought trying to surface, but it was one I wasn't quite prepared to look at just yet. So I just focused on what was in front of me.

"Kid, what in the Sam Hell?" Bobby asked. I took a second to remember that expression. I'd heard him say it before. Sam… Sam didn't have his own personal hell. Bobby had said that a few times. That memory helped me re-focus.

"It's all right, okay?" Jack promised. "He's here to help."

"He is?" Bobby sounded about as trusting as I felt. Lucifer walked past him, following Jack's lead towards where Maggie was.

"You know it, Longmire." Lucifer replied with a wink. "Good to see you, Kylie. How's the noggin?"

"It's fine. I thought you were dead?" Lucifer offered a downward wave of his hand in response.

"Fake news. Wouldn't want to bore you with the details." He assured me, continuing to follow Jack. I turned to Mary, and watched her follow Jack and Lucifer.

"Call Sam." She told me. "Now."

"Tell him he's an ass!" Lucifer shouted from the other room. Bobby followed Mary next. I pulled out my phone to do what she said.

"Sam can't talk right now," Dean's voice, almost immediately.

"Dean?" I asked. It kept going. I double checked for a second to make sure I had the right phone number.

"Cause he's waxing… like, everything." Still Dean's voice, but I had definitely called Sam.

"Dean this isn't funny, this is important." I tried. Sam interrupted.

"Dean, come on!" Sam's indignant voice, then the beep. Ah. Definitely voicemail, then.

"Sam, it's Kylie. Call me back. There's, um…" I wasn't certain how to phrase it. "Jack is here. With Lucifer. Please call me back." I hung up, and tried Castiel's phone.

"This is my voicemail." Definitely Castiel, and also immediately after I called. "Make your voice... a mail." It had gone to voicemail without even ringing.

"Hey Cas, um, tell Sam to check his voicemail. Lucifer and Jack are here." I paused awkwardly, unsure of what to say. "See you when you get back." I hung up quickly after that. That just… That sounded lame.

I looked at Dean's number for a moment, and decided against it. Jack said Lucifer was OK, and I trusted Jack. Calling all three would make them think this was an end-of-the-world type of alarm. Calling two? Alarming, but nobody is dying.

But why didn't either of the two pick up? Especially if Jack was with us. They went out to find him, shouldn't they have known that Lucifer was with Jack?

Unless something happened.

Something that wouldn't make them able to call. Or answer. Or would have them not know that Jack was here with Lucifer.

"I'll just ask Jack." I decided, taking a breath. No need to worry or panic, everything was going to be OK. This world was safe, there had to be an explanation. I pushed down that thought I didn't want to look at.

I walked in just in time to see Maggie sit up and gasp for air, and see Lucifer's eyes glowing red. Jack was smiling beside him.

"Maggie?" Bobby and Mary rushed to her side instantly, checking her vitals and making sure she was OK. I looked from Maggie to Lucifer and Jack, and in that instant saw three very important things.

The first one was how happy Jack looked. He looked proud of himself, and proud of Lucifer. Maggie was alive. The world was right again. Everything was OK. He just… he looked happy.

The second was Lucifer. His eyes were still glowing red when he looked at me. He offered me a smile that didn't quite look as kind or happy as Jack's. Instead, it looked… Knowing. Menacing. Sadistic. He knew something, it was a secret, and he enjoyed that secret a little too much. How did he get back? The thought I didn't quite want to look at tried to follow behind that question, but I shoved it down again as I looked at Jack and Lucifer.

In that moment, the two didn't quite look like father and son. They had the pose down right, with Lucifer's hand on Jack's shoulder and Jack's beaming smile of happiness aimed at his father. That was it, it was that smile; they were too different. It was like looking at polar opposites.

I didn't have to look for long, though. That was the third thing.

In an instant, the pair disappeared.

"Jack?" I asked. Mary and Bobby turned to see them gone, too. Mary turned back to me.

"Did Sam answer?" I shook my head.

"Neither did Cas. I was about to ask Jack if he knew what was up, and then," I motioned over to where they had been standing prior.

"Try them again, and call Dean. Tell them Maggie is alive." She turned her attention back to the girl after that. Maggie looked a little lost and confused and very much so frightened and scared. She was still taking large, heavy breaths, as though they might be stolen again at any second.

I left the room and did as Mary instructed. Still no answer from either of the three. No ring, just straight to voicemail.

"Hey Cas, it's Kylie again." I did my best to sound less awkward. "Maggie is alive, but Jack and Lucifer are gone. Please," I took a breath. "Please call me back when you can. I'm… I'm worried." I admitted. There was a second question in the back of my mind I was doing my best to ignore, because that question would just worry me further. "I know it's dumb to be worried and that you can take care of yourself, but none of you three are answering so please," another breath. Another pause. I shouldn't be worried. I'd just said why I shouldn't be worried. They were two grown-ass men and an angel. They were fine. "I'm sorry. I shouldn't worry. I'll see you when you get back."

As I hung up, I felt that thought I didn't quite want to look at finally forced its way to the surface.

If Lucifer made it here, did anybody else come with him?

I stared at the phone, that thought running around and around inside my head. I didn't bring Lucifer. Jack didn't do it. We both had thought he was dead. Sam and Dean and Castiel didn't do it.

Could Lucifer have opened that door himself?

"Jack would've said something." I muttered, trying to work it out. I wanted to convince myself that Lucifer had walked out himself. I needed to know that that was the truth. I walked away from the others, pacing in the main room as I tried to figure it out. "If Jack had opened the door to go and get Lucifer, he would've said something. If I had opened a door," I looked down at my hands. "I would've known. I… I should've known that a door had been opened." I thought on that. "But I didn't. Then again, I didn't hurt when Jack used his powers either." I shook my head. "I didn't know it opened, and I didn't do it. Jack didn't do it. The other witch… Rowin," that wasn't quite right. Almost, though. "No, Rowena." That was who Charlie was with. "She and Charlie are busy, so they're not local and probably didn't do it. Maybe we should call them to double check later, though." Maybe it was just Rowena? That didn't set right either, though. Rowena knew the Winchesters pretty well, wouldn't she have said something to them? "I didn't do it. Jack didn't do it. Rowena and Charlie probably didn't do it. If Lucifer opened the door himself…" What did it take to open a Rift? I could feel it somewhere, somewhere in my brain, but I couldn't quite remember what it was. "Grace. A part of it is grace." Someone had mentioned that in explaining how the Rift had stayed open as long as it had. "Archangel grace. Lucifer could've used his own. Would he have enough left over to get himself across and still bring Maggie back? How much power did that take?"

My head hurt trying to put it all together. I didn't want there to be another person. It had to just be Lucifer.

The door opened, the main one, and I looked up to see Sam, Dean, and Castiel running in. "Mary!" I shouted quickly. "They're back!"

"Where's Jack?" Sam asked frantically. I felt my heart sink at those words. They looked panicked. Something was wrong.

They didn't know Jack had been here.

They didn't know that Jack was with Lucifer.

If Lucifer made it here, did anybody else come with him?

Mary, Bobby, and Maggie walked in, with Mary offering Maggie support as they did.

"He's not here." I told the boys. Sam looked from me to Mary for confirmation.

"He's gone." She said.

"I've been calling you guys, why didn't you answer?" I asked. Castiel looked over at me. He… He looked scared.

Nobody said anything for a few moments. I could feel concerned eyes on myself and Maggie.

"Maggie, lets go sit down in another room." I heard Mary say. "We'll get you something to drink." I kept my eyes on Castiel. He fixed his expression quickly from one of fear, to, well, I wasn't quite certain. Something beyond determined. Something that wasn't going to let fear get in the way. Something changed in his brain, in that moment; something I probably wouldn't ever learn about.

Once Maggie was out of earshot, and Mary came back, the boys told us what had happened. They told us that Michael had come back.

I felt something tighten in my chest at that. Maybe it was my own fear, or my own determination. I wasn't quite certain either, but I understood it.

We all took a seat around the big map table thing, letting the news sink in around us. Michael was back, in this world. Lucifer had just disappeared somewhere with Jack. It was… A lot. It left open a whole new host of questions to try to both answer and know to ask, and not a lot of time to get it figured out in.

"We can't tell the others." I decided, looking at Bobby. "Not now. Not when they've just started to feel safe."

"But we'll need fighters." Bobby pointed out.

"How did Michael and Lucifer both get here? How did they open a rift?" Sam asked, looking over at me. I put my hands up.

"I got nothing." I said. "I… I should've felt it, but I didn't."

"You know what?" Dean said. "It doesn't matter. We - we've gotta find Jack before Michael does whatever the hell he's gonna do, okay?" He took a breath. "I-I'll call Jody and everybody else."

"You're gonna put out an APB on the Devil?" Bobby asked incredulously.

"What's an APB?" I leaned over to whisper to Cas. Dean confirmed to Bobby that that was exactly what his plan was as he walked away.

"It's like telling other humans that a person is a bad person, and to tell us if they see him." Castiel explained. He thought for a moment. "I'll check angel radio." He decided, walking away to another room as well. I looked around at Mary and Bobby.

"We need fighters." Bobby repeated.

"They'll never feel safe again if we tell them." I argued.

"They'll never feel safe again if we don't." Mary pointed out calmly. I gritted my teeth. She was right. They both were. I didn't like it, but they were.

"Fine." I agreed. "Let's get a force together." I looked around a bit, trying to find a way to feel useful. "I… could I ever use magic to find someone?" I looked at Mary for that. She nodded. "Great. Jack said I had to keep practicing magic. I guess necessity is a good reason to learn tracking spells." I got up from the table. "Was there a room here I used as a workspace or anything?"

"Down the hall, first room on the right. It's probably pretty barren." Mary said.

"I can drag in a small table and a chair, get a hold of some books." I decided. "I'll see if I can find him or Lucifer or Michael."

"I'll start making calls." Bobby decided.

"Even if we find Lucifer, how are we gonna stop him?" Mary asked Sam. I stopped, as did Bobby, as we both turned to look at them.

Sam looked at all of us for a moment. I could see him thinking, but he didn't have an answer.

He didn't have an answer. He didn't want to say that, either.

"Then we figure it out from there." He decided. That was the closest he'd get.

I walked back towards the room Mary had mentioned, and found a small table and chair already waiting outside it. I took a look inside the room, and saw it was empty. There were marks along the interior walls that showed clear damage, but from what I wasn't certain.

But I knew it was from me. This had been my workspace. I didn't know how I caused the damage, but I knew I had.

I dragged the table and chair inside, and went back out into the library to pull books. They were organized, somewhat, by their purpose. I did my best to find a few books specifically located under "locate" and "find," and ended up with five. Bobby was pacing somewhere nearby making a few calls. He didn't specifically mention what it was we needed people or help for, just that we might need fighters sooner than later. Sam and Mary were sitting and speaking with Maggie. Castiel walked in from wherever he had been.

"Hey Sam!" I shouted. He looked up from his conversation. "If I was looking for ingredients, where would I be?"

"I'll show you." Castiel offered. I nodded, and he led me down to another room not too far from the kitchen. "What do you need?" He asked. I felt myself pause.

"I… Ah…" I looked at the books in my hands. "Let me look through these, and I'll have a better idea." I decided.

"OK." Castiel nodded. He looked over at the books and ingredients in front of me, took a breath, and started to walk away.

Then the weight of exactly what I had to do dawned on me, and I suddenly felt very, very small.

"Wait." I found myself saying suddenly. Castiel stopped and turned. "I… It'll be faster if we work together." I said. "I don't know if we have enough time for me to read all these books, play Pictionary with components, and test out different spells, all while I'm trying to crash course myself back into magic right now."

"OK." He repeated, walking back towards me. "I have a few recommendations, if you would like to hear them."

"Sure." I nodded, and listened as Castiel pulled a few herbs and ingredients and explained what they were along with their purpose and how to identify them. Different things to help with sight, seeing, finding what you want, gleaning information, things like that. "You'll also want something of Jack's, something of his essence." Castiel included. "I think I know where some hairs are, or a feather or two."

"OK." I nodded, taking it all in. Everything he was saying made sense, but at the same time it felt like I was learning a language that I'd known for a long time, but hadn't used in an even longer time. It was both foreign and familiar, and I could feel the information slowly starting to slot itself where it was supposed to be.

"This book is useless," he pointed to one of the ones in my stack. "Entirely theoretical. The notes you would've taken are better. I think some of them are still in Jack's room when he was studying them." I could see him think for a moment. "I think we'll want to add these ingredients, if I remember your books correctly. You wrote them in code, but I've been working on translating them."

"I wrote my own magic spells in code?" I asked. That both sounded insane, but also completely like something I would do.

"Yes." He confirmed. "A very difficult code, I might add."

"Oh. Sorry about that." I muttered.

"Don't be. It was… an entertaining challenge." He admitted. "I'll meet you in your workroom with the notebooks."

And just like that he was gone.

"Huh." I muttered.

I met Castiel in the workroom, just like he said, maybe five or eight minutes later. He had a stack of notebooks, and I was starting to set up a baseline for a tracking spell.

I wrote a symbol near one edge of my circle, thought about it, and erased it to scribble a new one in its place. A better one. Two more over here on the left, a fourth in the lower center, and one in the middle for Jack. The one I'd written on the right was already correct. I drew another circle around Jack's name, and connected it out to my larger circle.

Once I started working, I felt more gears slotting into place. I'd done tracking spells before. I'd done a plethora of tracking spells before. In fact, the blue and orange notebooks that Castiel had brought in should be filled with some tried and failed attempts from when I was…

When I was….

I blinked, and I was out of it. I stopped, a notebook open beside me, some miscellaneous ingredients resting on top of it, and a bowl sitting on top of my center symbol in the middle of my two circles. I couldn't read the symbols, even though I knew I'd known for just a second what they were.

"What?" Castiel asked. I jumped, forgetting he'd been there. "What's wrong?" He asked, coming closer.

"You startled me." I muttered, offering a shaky laugh. "Sorry. Just… I almost had it."

"What do you mean?"

"I mean I," I took a breath. "I had it. I had it, for just a second. I knew what I was doing. I felt," I motioned awkwardly with my hands. "I just felt it. I knew what I was doing. I felt like I had been doing this all my life, and I could remember doing something like this before, but the second I got close to it, I lost it." I let my hands fall to my side as I went to stand back in front of the table. "I almost had it, and I lost it."

"It's OK." Castiel commented. "You'll get it again."

"How long do we have?" I asked.

"Until what?"

"Until Michael finds us."

Castiel didn't answer for a few moments. "Don't worry about that. Just focus on what we can do."

"Are you getting anything on angel radio?"

"No. It's just static for right now."

"That's not good, is it?" I asked. Cas didn't even bother to answer that time. "Fair enough. Work on the problem at hand, you said?" He nodded. "OK."

"I'm going to go talk with Sam and Dean." Castiel said. "Do you have your angel blades on you?"

"Yes." I flicked my wrists to show him.

"Keep them on you." He didn't exactly say it like a command, but I knew it was more than a request.

"Can do." I promised. "Let me know what the boys say."

"Can do." He repeated back. I returned to the desk, and he left the room. I took a deep breath.

"OK. Fine. I can do this." I muttered, turning back to the notebooks. "I've done it before. I can find it again." I've done this before. I've done this before, and against bigger things than a lost Nephilim. "I can do this."

I took a few deep breaths and tried to relax. I knew what symbols I'd been writing, even if I didn't know it now.

I flipped back to my notes, carefully nudging aside the ingredients. They were there for a reason. I was on this page in the orange notebook for a reason.

The circles in the middle were similar, but with slightly different symbols. These had been for finding someone else, but they could be modified for Jack. That's what I'd done, I'd modified it just slightly, just so it would find Jack.

I want to find Jack. My intent is to find Jack.

Find Jack.

I picked up one of the things that had been on the notebook, an herb I couldn't name but knew why I needed it. I held my hand out, and a map Castiel had brought in moved from the side of the room to my hand. I put my hand in front of me, flattening the map against the wall. With my other hand, I put more things into the bowl and ground them up. I didn't focus too hard on what I was doing, I knew I'd get it done.

I just had to find Jack.

The last thing I needed was a feather, one of Jack's. I held it with my free hand, the map still pinned against the wall.

"All I want is to find Jack." I muttered quietly, feeling the feather start to light on fire. I placed it in the bowl, and kept my hand in it as the rest of the ingredients began to light. "Show me where Jack is."

The fire shifted, from the hand in the bowl to the hand I had extended. The smallest, thinnest flame left it, burning a small hole in the midwest section of the map.

I closed my hands, and took another breath. There was a small burn hole in the Rocky Mountains National Forest.

"That's where he is." I muttered. "I did it." I let out an excited shout. "I did it!" I ran out of the room, map in hand, to see the others. I had to show them. I had to let them know I'd done it.

"Guys! Guys!" I stopped at the sound of banging. Cas, Sam, Dean, Mary, Bobby, and Maggie were all looking at the door as the lights started to flicker.

"Oh no." I heard Sam mutter.

"What the hell is that?!" Bobby shouted.

"It's him." I muttered. "It's Michael."

"Mom, Bobby, take Maggie and get her out of here." Sam ordered. "Go through the garage." As he spoke, the door began to shake.

"We'll buy you some time." Dean promised. Castiel looked back, and saw me standing there with a map.

"Kylie," he said. "You have to run."

"No!" Mary shouted.

"Mom!" Dean argued.

"Please!" Sam pleaded.

I looked from Cas to the door. The banging was louder, and it was shaking harder and harder.

"Go!" Bobby ordered, pulling Maggie and Mary with him.

"I'm not leaving you, Cas." I said. "I won't leave you." I held the map in my hands, and felt a spark at my palms. In an instant, the map was ashes at my feet. "I'm tired of running."

I could see a thousand emotions flicker across Castiel's face in that instant, but only one matched the small smile on his face. "OK." He nodded.

Then light flooded the room, and the door flew off it's hinges.
