As S8/E20 finishes, Dean and Sam hit the road after thinking Kevin has ditched them. Suddenly, Castiel appears to them, but he's not alone. Who he brings with him, will change everything for Sam and Dean, forever! In a twist of fate, there's another Winchester thrown into the mix, and its someone that no one saw coming.

The idea of Winchester Witch is a story that came to me in dream, believe it or not. Even after a couple of days, it was still stuck in my head, and I just felt compelled to write it out. I've been watching Supernatural for the last few months, and I'm currently towards the end of Season 8, so that's where my story starts out. I have no idea where Supernatural is set to go - as i keep away from any spoilers - But, I do know the Supernatural fandom is vast and very passionate. All rights and major props go to its creator and writers, and no disrespect to any of them or the fans is intended at all. All that said, I hope you like it!

Winchester Witch

CHAPTER 1 - DeanPOV

.

Walking up to the driver's side of the Impala with the bag held in the nook of my elbow and a soda in either hand, I noticed Sammy was asleep against the passenger side window. With both hands full, I realized I had to wake him. With two trials completed, I hated to wake him but he had to eat anyway.

"Sammy! Bro, a little help!" I called out, making my voice loud enough to be heard from the inside of the car.

A guffaw escaped me, when I saw him jolt straight up and look around, as if to asses any danger. By the time his wild eyes noticed me standing beside the Impala holding the food, he shook his head and relaxed his posture. I'm pretty sure I saw him mumble 'jackass' before reaching over to open the door for me.

"Morning, Sunshine." I greeted with a wide smile as I got behind the wheel of my baby, and handed him one of the sodas.

"Yeah... Thanks." He said then took a greedy gulp of soda, sighed and rolled his neck.

I dug into the paper bag and pulled out my burger and placed it on my lap and did the same with my fries. I mentally rolled my eyes as I reached into the bag and pulled out Sammy's salad and dressing packet. How the boy could find such enjoyment out of eating that stuff, would forever be beyond me. I left one last little box of perfection inside the bag for later.

"Oh, good. Thanks Bro." He told me genuinely grateful.

Aside from the almost paralyzing and practically all consuming fear of everything he's been through and the unknown of what's yet to come, I was immensely proud of Sammy. There isn't much else I can do for him these days, so I was happy to spend a few extra bucks for his salad.

Nevertheless, I nonchalantly responded, "Figured you'd had enough burgers over the last few days".

I focused my attention on arranging my drink and fries on the seat beside me, so they wouldn't spill and reached for my burger. As I started unfolding the wrapping, I could tell he was looking at me. Naturally, I wasn't exactly ready for a deep expression of gratitude or anything of the sort and he must have picked up on that. I mentally relaxed when I heard him sigh and turn his attention to his own lunch.

I felt my mouth watering as the burger's aroma filled my nose. I'm not ashamed to admit I moaned as I took a big bite. It didn't even bother me that Sammy chuckled at me either. Hell, I smiled at him around a mouthful of bacon burger deliciousness. I took a swig of my soda to finished swallowing it down and munched on a few fries. We finished our meals in comfortable silence for a bit longer with the windows down, just enjoying the afternoon.

"So, back to the Bunker?" He asked me, after finishing his salad and taking a sip of his soda.

I simply nodded, because my attention was on opening the small triangular container I'd saved in the paper bag. In it, was the last slice of pie from the diner where I'd just gotten out lunch. I could almost savor its cherry goodness as I put the plastic fork into it, ready for my treat.

"Sam. Dean." Castiel's voice said suddenly from behind me, surprising me so much, that I fumbled my hands and accidently tossed the slice of pie right out the window.

"Dammit… Cass?!" I exclaimed, questioning angrily.

I looked out enough to see the entire slice, fork and all, splattered on the asphalt beside my door. None of it salvageable.

I turned towards the backseat, ready to reproach Cass for his impeccable time as always, and barely missed the look of shock on Sammy's face. Almost instantly, my own eyes then focused on Cass... or rather the thing Cass was holing in his arms. Before I could formulate any words in response to the scene before me, it removed a grubby little hand from its slobbery mouth, only to reach out and grab my nose.

"Cass, what are you doing with a baby?" Sam asked as I jerked my face away from the tiny tot's gooey fingers.

"Ugh", I commented as I used my sleeve to wipe my nose and face.

"She must be protected, and I can be tracked … we have to keep moving. We cannot remain stationary out in the open like this for too long." Cass told us, but looked us each in the eye.

"Alright…" I paused, taking in his words, but still needing more. "Why? And, why us? Whose baby is this, Cass?" I asked him.

I figured there had to be more to this … this baby… than met the eye. There had to be a reason an angel would come out of hiding and suddenly show up looking very out of sorts, for a usually expressionless Cass.

"What I have to tell you will probably be difficult to believe, but you must." He told us, seriously and urgently, which only prompted Sammy and I to look at each other for a moment, then back at Cass, waiting for him to elaborate.

"She is a Winchester, and shares your blood. More precisely, the child, she is your sister. Of this, I am certain." He told us, and I immediately released the breath I'd been holding by breaking into a deep bellowing laugh.

"Yeah… Oh, Cass, that's a good one." I said between my laughs.

I looked to Sam's face expecting to see him laughing too. Instead of laughing, he was looking towards Cass with a weird expression on his face. But more than that, he was staring in shock at the baby in Castiel's arms, which made me look in their direction as well. I wanted to continue laughing, but the look on Cass's face made me sober up. I looked at the child again, trying to understand or make sense of what Castiel was trying to make us believe, but I just couldn't.

"Cass, you must have lost your mind again. This is crazy – ridiculous, actually! How can you expect us to believe the kid's our … sister? It's still a baby for goodness sake." I told him, still trying to bring rationality into this crazy situation.

"Yeah Cass… How can you say you're certain? Cass, it just doesn't add up. Mom died when I was a baby and Dad died years ago." Sam – the voice of reason spoke, echoing my thoughts.

"Boys, I will explain everything, but right now, we must move and quickly. Dean, drive!" Castiel said forcefully, leaving no room for argument.

I turned to Sam, who looked skeptical but shrugged his shoulder and nodded at the wheel. I sighed and turned in my seat. Dozens of thoughts still swirling around in my mind, and each one proved the kid couldn't possibly be our sister. Yet, something within made me want to believe this; something I couldn't explain.

"Move it Dean, go!" Castiel urged once again.

"Fine, ok." I said with one last look at Sam who nodded as I turned the key in the ignition. "I drive and you talk." I told Cass as I looked at him through the rearview mirror, then pulled out of the parking spot.

"Castiel, you've been gone, just disappeared for a while. You haven't made contact for months, since you took the Angel Tablet, we don't know where you've been. Now, you show up with this baby you claim is our sister." Sam recounted, voicing some of my own thoughts.

"Please make us understand how you think this could possibly be our sister. Man, I just can't make sense of this at all." I admitted, while I pulled onto the highway.

"Alright. Just, don't ask about the Tablet. It's safe and that's all I'll say about it. Where would you like for me to start?" Came Cass's response.

"Fare enough." Agreed with a grunt, following the highway signs that would lead to the bunker.

"Okay, start with when you found out about the baby." Sammy told him and I nodded.

"It's a long story, but I'll tell you everything I've learned." Castiel replied.

A/N: I was finally inspired to write again and I'm so HAPPY to be back! I have so many ideas of where I'd like this story to go. But I have so many things going on in my life, so I want to make sure people at least like the beginning, before I set aside some time every night to write more. Let me know XOXOX!
