Imagine: instead of Sam you were infected with demon blood and starting going off the rails. Will your brothers reach you in time before you get too far gone?

This will be a two part series.

First's P.O.V

*17 years old*

Blood. That's all I can think about now. More specifically, demons blood. Holding that knife in my hand as I cut the demons arm slowly, watching as the fresh drop of blood slowly makes its way down their arm.

That's all my mind can think of, is that first drop of blood.

"Y/N come on we gotta go," Dean pounds on the motel bathroom door.

I splash cold water on my face trying to overcome the thoughts, but in the end they're apart of me. How can you kill something that's attached to you? I dry off my face taking a deep breath before exiting the bathroom.

I see my brothers throw their bags over their shoulders.

"Is there a new job already," I ask grabbing my bag.

"Yeah in Montana," Sam throws me my stuff animal before opening the door.

I follow behind Sam with Dean behind me. I feel guilty about keeping this secret from my brothers but they wouldn't understand. How could they? I'm a whole new level of freak and with everything going on I would just be a problem.

I know they want what's best for me but maybe keeping my mouth shut is what's best for them.

"Hey mouse you okay," Dean looks in the rear view to meet my eyes.

"Yeah I'm just sleepy," I lie.

"Well get some rest we have 10 hours ahead of us," he puts the car in reverse driving away from the motel.

I rest my head against the window holding my stuff animal close to me. The urge to feed is getting stronger, and I'm afraid that I won't be strong enough to stop it this time.

*********************

We pull into a gas station after driving hours. I feel like it would never end.

"I'm going to stretch my legs," I open the car door welcoming the summer night breeze.

I hold my arms above my head stretching.

"I'm going to grab some food. Want anything," Sam asks stepping out of the car.

"Yeah some sour gummy worms and skittles," I reply doing a few more stretching moves.

"What's with you with those sour gummy worms," he mumbles starting to walk away.

"You're just jealous," I yell out chuckling.

He waves me off and enters the gas station. I look from the corner of my eye to see ruby standing in the shadows by the bathrooms. I look back to see Dean focused on the gas pump.

"Hey D I'm going to use the restroom," I walk away from the impala going over to ruby.

I look back to see Dean still turned towards the pump.

"What are you doing here," I grab her wrist pulling her towards me.

"There's a town nearby with some demon infestation. I know one of them knows where Lilith is," she tells me.

"My brothers are going to Montana I can't just ditch them,"

"Y/N if we know where Lilith is then we can stop her from releasing Lucifer. You need to remember what's at stake here,"

"I get that Ruby but my brothers-"

"Please y/n find a way," she begs before disappearing.

I groan leaning against the building. Shit. I harshly push myself away from the wall before going back to Dean.

What the hell am I going to do? I need to find answers but Dean is set on Montana.

"Hey you okay," Dean asks as I get back in the car.

"Yeah something weird happened. I was leaving the bathroom when I overheard some people talking about some freaky stuff happening in the town nearby. They said some people had black eyes and were acting crazy," I lie.. I seriously hate lying to them.

But if I can defeat Lilith then the weight on their shoulders will be lifted by a lot.

"Maybe we can detour," Sam looks at Dean shrugging his shoulders.

Dean sighs starting up the car driving away towards the town.

***************

I sit up carefully making sure to not wake Sam. I slowly get out of bed grabbing my shoes. I tiptoe softly making sure to not make a sound, not even a creak. I can see Dean with his hand under his pillow softly snoring. No doubt he has a gun under it.

I finally make it to the door unlocking the chain lock slowly. I hold my breath praying that it doesn't wake them. I open the door slipping out then shutting it behind me. I wait a few seconds but don't hear any rustling come from our room.

I let out a breath of relief as I turn to see ruby already standing by a worn down mustang.

"Finally," she rolls her eyes getting into the driver seat.

"You try sneaking away from two very good hunters," I reply harshly tying my shoes.

"Well luckily we're near where we need to be," she drives away from the motel heading into a town.

We past a few houses before turning into a diner parking lot.

"A diner?" I ask skeptically.

"I never said demons were the smartest," she takes out the key and we exit the car.

"So what's the plan," I ask as we get closer to the diner door.

"Simple. You do your thing," she shrugs like it's nothing.

"Wait what? Ruby I'm dry I haven't had any... you know what.. since the last time," I grab her before she can open the door.

"Are you serious?! Y/N I told you you need to be feeding constantly to reach your potential," she pulls her arm away groaning.

"It's hard when you have protective brothers breathing down your neck," I yell becoming irritated.

I mean what does she think I should do? It's not like I can put blood in a water bottle and take it with me. Hey Dean I'm going to go refuel be back soon!

Like what the hell.

Ruby pulls me away and rolls up her sleeve. She takes a knife and cuts her arm and I watch as the blood gently rolls down her arm. I can feel my mouth water as I take her wrist.

"Enjoy," she nods at me and I bring her arm to my mouth.

*Sam*

I'm awaken by a rush going through the room. I grab my gun raising it as I turn to see Cas standing there looking at Dean and I.

"Cas what the hell man," Dean groggily says pulling the covers away from him.

"It's Y/N; she's in trouble," he speaks sternly.
