Sorry this chapter is small i edited out a lot of stuff to help the flow of the story better.
After half an hours drive Dean pulled the car into a gravel path facing an old run down cottage with smashed windows and holes in the roof.
"Quaint." You commented sarcastically.
"It's the last place people will look so we should be safe." Sam replied.
The three of you got out the car and took a moment to look at the creepy looking cottage.
"You know if you wanted to do a ghost hunt you could have left me at a hotel."
They both turned around giving you their bitch faces making you laugh a little.
"What? This place looks haunted."
"I'm pretty sure it's not. Just run down is all." Sam reassured as Dean handed him a duffel bag and shotgun from the boot of the car.
You let them go in first, shotguns loaded with rock salt. Once they gave you the all clear you went inside.
The ceiling was full of holes and the bottom half of the stairs lay broken in a pile on the floor. Bits of broken furniture lay scattered throughout. There was a dark patch of wood that stood out in the kitchen and you remembered reading an old newspaper article about the place.
"I read about this place a while ago." You said out loud.
Both guys looked at you as if wanting you to explain.
"Back in the late 40's a young couple lived here. The husband was believed to have murdered a young boy and some of the towns people broke into the cottage and beat him to death, apparently they even threw him down the stairs. They accidentally killed his wife when she tried to stop them. They disposed of the bodies somewhere but no one ever found out where. A month later the police arrested a local man who admitted to killing the boy. The townspeople felt guilty and those involved in the murder of the couple either came forward to the police and were arrested or disappeared."
"Those poor people." Sam said sadly.
They set out three old sleeping bags and a few portable lights. Dean went on a supply run and by nightfall the three of you were munching away and trading funny stories. You were having a good laugh at their tales and them laughing at yours. You began to realise a bond was forming between the two of them and you.
The next morning you rubbed your eyes and sat up. Although you had slept reasonably well your back hurt from sleeping on the hard floor. You got up and looked around. The place was empty. Both Sam and Deans sleeping bags were already rolled up.
You called out but no reply. You began to worry. You could hear something outside and quickly grabbed a plank of wood and raised it ready to defend yourself.
The door swung open and both your brothers stepped inside.
"What the hell are you doing with that?" Dean asked slightly amused.
"I thought maybe the demon was here or something." You replied lowering the plank and feeling ridiculous.
"I went for some breakfast and Sammy here went for a walk. No demons."
Over the next few days you had grown closer to your brothers. Sam had started showing you the journal they had describing a wide range of monsters and how to kill them while giving you brief descriptions and Dean had given you shooting lessons in the nearby woods and also a few tips in defending yourself.
For the first time you actually felt like you belonged and wanted as part of a family.
"Y/N. There's someone we'd like to introduce you to." Dean came over to you while Sam was explaining how to kill a werewolf.
With a slight breeze a dark haired, blue eyed man in a suit and trench coat appeared.
"Y/N this is Castiel. Cas for short. He's an angel and he's like a brother to us. Cas this is our half sister Y/N."
"Nice to meet you Y/N." Cas' voice was deep but you could tell he was ok.
"You too. Can't believe I'm talking to an angel." You giggle.
Cas smiles at you and then tilts his head slightly to one side and squints a little as if trying to figure something out.
"Cas what's up?" Sam asks curiously.
"I think I know why demons are after her."
"Care to share?" Dean asked.
