You have lived with the Winchesters for what has seemed like forever, but really its only been 5 years. You grew up in a tough place, you had to learn how to defend yourself. You're parents were strict and very superstitious, so they taught you how to protect yourself from evil spirits and entites. They even taught you an excorcism. Sometimes, on friday nights you and your Father would go hunting for deer or anyother food since you lived in a forest a couple miles away from anyone else. You and your father would pack up some holy water, just in case, and you would grab your hunting rifle. Everything was was perfectly normal (for your family) until one night after eating dinner and heading to sleep, you found it hard to sleep. You lay awake on your bed when you hear your parents screaming. You quickly leave your room and peek down the stairs, what you saw was horrifying. Your mother and father were on the floor squirming being torn to shreds by absoultely nothing. You didn't know what to do and you slowly backed up. When you did so a board creeped beneath your feet and you froze. The ripping paused on your parents, you could see your father was already dead but your motjer looked at you and said,
"RUN (Y/N) DON'T LET THEM CATCH YOU, RUN!"
Next thing you knew, your mother's head was bitten off, dangling there in its invisible mouth before swallowing it whole.
You didnt think twice, you turned and ran into your room locking it behind you. You opened your window and looked down the drop wasn't very far. You jumped, tucking and rolling so you could recover quicker. You immeaditly stood up and ran screaming for help. You made it to the road and almost got hit by a black '67 impala. It squealed to a stop and two attractive men stepped out.
"Hey are you ok?" the tall one asked
"No please hel-" you attempted to say but you were tackled by the invisible creature.
"PLEASE HELP ME I DONT KNOW WHAT'S HAPPENING!" You managed to get out as loud as possible. You were being ripped to shreds by something you coouldn't see or even hear.
You heard the shorter one say something about a hellhound, and then you saw him put on glasses and run towards you with a knife. You closed your eyes as he stabbed, but opened them when you saw it pushed through something large. It was bleeding all over you and he kicked it over leaving it on the ground dead. He picked you up and set you on the hood of his impala and began to check your wounds.
He sighed with relief, "They aren't as bad as I thought they would be, it must have been a smaller one."
The taller one walked over and started to patch me up as the other keot checking wounds. Suddenly I remembered something my father tought me. I reached into my pocket and pulled out the small thing of Holy water and splashed it on them, good they aremt demoms I thought. It was the first timed I moved without them helping me and they looked suprised, and even more suprised when i splashed them with the Holy water.
"My name is Dean and that's my brother Sam, who are you and how do you know about Holy water." said the shorter one.
You looked at them, and shakily told them everything, from learning about everything up to now. More stuff happened but thats all smaller details, they ended up taking you in and teaching you everything they know.
