Imagine the beginning of the apocalypse.
First P.O.V

"Dean," I  yell as a vampire sneaks behind him.

Dean turns, cutting the vamps head off with his machete. I sigh in relief, jogging up to him. His phone rings, and he reaches in his pocket to pick it up.

"Hello," he asks.

I can hear talking on the other end but can't determine what the person is saying.

"Woah, Bobby, calm down; what happened," Dean looks at me, then at Sam.

"We're on our way," Dean turns off his phone, nodding at us.

"What happened," Sam asks, coming to my side.

"I'll explain on the way. Come on," Dean starts running to the impala with Sam and Me behind him.

*********

"Wait, so Lilith is trying to break the final deal," I ask, confused.

"Yes," Dean replies, speeding down the dirt road.

"And Sam is the one who will break it," I slowly ask, trying to process this whole thing.

"Correct," Dean makes a sharp turn.

"That will never happen," Sam snaps from the passenger seat.

"I'm not taking any chances. You and Y/N are staying with Bobby," Dean glances at Sam for a split second.

"What," Sam and I say in unison.

"I get why Sam has to stay, but why me," I whine.

Sam looks back at me, squinting his eyes. I shrug, looking back to Dean.

"Because I don't need my little siblings getting hurt while I try stopping the end of the world," Dean finally stops in Bobby's driveway.

"This isn't fair! I refuse to sit around while you sacrifice yourself," I yell, getting out of the car.

"Dean, I'm not letting you go alone. You can keep me on a close leash or whatever, but you're not doing this alone," Sam looks Dean in the eyes.

"Fine, but you're sticking with me,"

"Oh, come on! I'm (you're age)! I'm not six anymore, Dean," I yell, stomping my foot.

"You stay here with Bobby. End of discussion y/n,"
Dean sternly says.

I roll my eyes in disbelief. I can't believe this; no matter how old I get, I always am treated like a baby. I'll show them myself. I'll show them that I'm strong and that I'm the best hunter they have ever seen.

*********

I stare at my reflection in the mirror. I take black face paint and make smudges around my face.

"Hey, kiddo, you okay," I hear uncle Bobby knock on the door.

"Not really. I'm just going to try to get some sleep if that's okay," I reply through the door.

"Yeah, I'll be in the living room if you need anything," Bobby replies, and I hear his footsteps leave the hallway.

I tighten my braid and slowly open the door. I look both ways to see no one in the hallway. I close the door making my way to my room. Once I'm inside, I close the door and lock it. I put my combat boots on and give myself one last glance.

Time to show you how grown up I am.

*********

A cemetery? I look down at my phone to see my GPS leading me to this cemetery. Okay, well, who am I to argue against a demon? I park the car in between some bushes, so I'm hidden.

I get out to hear nothing, not even crickets. I quietly shut the door and look around to see nobody or no creature near. This is crap security.

I walk up to a building to see the door open and a blood stain on the ground. I sneak in, making sure I'm not being followed. I can hear some yelling down a hallway.

I feel a hand cover my mouth and something cold on my back.

"I've never had a girl before," I hear a snarl.

I slowly grab my knife and turn around, slitting the guys throat. His eyes glow, and he falls to the ground lifeless. I feel some of his blood on my cheek. Gross.

I turn around, making my way to the yelling. Halfway the ground starts to shake. Parts of the ceiling crumble around me, and I start running. I hear a loud thump, and the ground continues to shake.

I pick up the pace, hoping I'm not too late. Suddenly I stop to see something horrific. I see Sam holding out his hand that's pinning Dean to the wall. Lilith is on the ground smiling with her red eyes.

"Sam! Stop," I scream.

He turns, and his eyes are black. I step back in disbelief, tears starting to form.

"Y/N, get out of here," Dean yells at me.

Lilith laughs, and Sam raises his fist towards Lilith, who starts choking. I don't know what to do. I'm watching my brother turn on his own family. Sam released Dean, who ran to me.

"Wha... you," my breath becomes heavy as I watch my big brother kill Lilith.

"What are you doing here y/n?! You're supposed to be at Bobby's," Dean puts his hands on my shoulders.

"He— Dean wha-," I start hyperventilating.

"Come on, we're getting out of here," Dean starts pushing me out the door.

"Sam, stop, please," I scream, trying to get to him.

The doors slam shut, and Dean turns around, mumbling. We run to the doors, but they're stuck—Dean pounds on the door but nothing. Suddenly a white light starts emerging from the cracks underneath the door.

I take a step back, looking at Dean with terrified eyes. All of a sudden, we're on a plane. I look around, confused.

"What the" Dean looks down at his chest and pats it to ensure he's not dreaming.

"Where are we," I ask.

"What happened," Sam asks from beside me.

"We are approaching Kansas again; thank you for flying with us tonight," the captain talks on the intercom.

*******^

We exit the airport to see Dean's car in the parking lot.

"Okay, what happened," Dean asks, looking around.

"We're in Kansas," I say.

"Well, thanks for the observation," Dean replies sarcastically.

We make our way to the impala silently. Once we get away from people, Dean slams Sam against the car. I stop walking, crossing my arms.

"What the hell sam," Dean yells at him.

"I'm sorry! I knew I could stop her," Sam barks back.

"You scared y/n! You betrayed us! We could've died in there because of your reckless thinking," Dean puts his arm against his neck.

"Dean, I'm fine," I interject.

"Stay out of this y/n. What Sam did was unforgivable," Dean snaps at me.

I stop talking. When Dean gets this mad, it's best to stay out of his way. The only thing worse than a bullet to the abdomen is Dean's rage.

"I'm sorry," Sam mutters.

"You broke my trust... I don't think I could ever trust you as I did before," Dean backs away, grabbing his keys.

Sam sighs, looking at me. I lower my head walking past him, not saying anything. I get in the passenger seat, sitting criss-cross. Sam gets in the back, not saying anything else.

"So what now," I ask, looking at Dean.

"We stick together," Dean starts up the car.

"Until the very end," I add, giving him a slight smirk.

He smiles, puts his hand on my lap, and drives away.
