Y/n is the Winchesters sister, she's 16 and Hunting with them when they heard about Drained bodies in mystic falls and people going missing. Sam is 22 and dean is 26

"Mystic falls. Huh sounds preppy." Y/n spoke.

"Looks preppy." Dean chuckled.

"Looks like a murder town." Sam spoke.

Y/n was in the back when they drove into town, they pulled up next to a Blue car.

"Huh looks like we're back in 1969." Y/n got out of the back seat slightly pushing Sam.

"Ooh look a bar." dean walked into the grill, Sam and y/n following behind.

"Y/n. You stay with me." Sam spoke.

"Got it." She nodded.

They went to a table while dean got drinks.

"Doenst look too bad here." Sam spoke.

"Ooh pool tables. Wanna play?" She questioned.

"Be prepared to loose." Sam chuckled.

The got over to a table by the pool tables.

After about 10 minutes dean came back with drinks and the waiter finally came back with y/ns fries and Pepsi.

"I win!" Y/n yelled.

"Oh whatever." Sam chuckled.

*later*

Y/n was standing and playing pool by herself while Dean and sam were researching.

"Hey, are you new in town?" A boy around y/n age walked up.

"Uh yeah I'm here with my brothers just stopping by for a few days." She nodded.

"Im Jeremy." He put out his hand.

"Y/n." She shook his hand.

"Can I join you?" He questioned.

"Sure, why not." She handed him the pool stick.

Dean and Sam were watching y/n flirt with the boy and laugh while eating fries.

"Hi I'm Caroline Forbes. You must be new in town!" A blonde girl walked over to them.

"I'm Elena, this is Bonnie." A brunette smiled.

"I'm dean and this is Sam." Dean smiled at Caroline.

"Who's with Jeremy?" Bonnie mumbled to elena.

Sam and Dean turned to see them looking at the same boy talking to y/n.

"That's my sister Y/n." Sam nodded.

*later*

Caroline was non stop flirting with dean, Bonnie was staring at Jeremy and Y/n, Elena was talking to Sam about the towns history.

"Hey Sam, dean. Would it be okay if I went to a party with Jeremy?" She questioned walking over and leaning on sam with one arm.

"Give us a minute please." Sam and Dean stood up and walked away.

"Did you find anything?" Sam questioned.

"Vampires." Y/n spoke looking at them both.

"No your not going not unless one of us goes with." Dean spoke.

"I'll go." Sam spoke.

*later*

Y/n and sam were in deans car and just got to the party, y/n saw Jeremy and a few others.

Y/n was walking when a tall dark haired blue eyes man stepped Infront of her.

"Who are you? Why are you here?" He tried to compel her.

"None of your businesses and none of your damn business." She spoke and he looked at her confused.

"Do we have a problem here?" Sam walked over towering over the man.

"Nope no problem." He walked away.

Sam and y/n looked at each other and followed him.

He got further from the party and Sam snuck up behind him injecting him with vervein and y/n opened the car door.

They got to the cellar where Dean was and they dragged him down.

"He's a vampire." Y/n spoke.

"Vampires. Get funnier everytime I say it." Dean spoke sharpening his blade.

*later*

Y/n was back at the party when she was shoved against a tree.

"Where's my brother?" A tall guy spoke.

"I don't- I don't know-" she spoke groaning.

"Where is he?" He yelled showing his vampire face.

"Stefan! Hey!" Jeremy ran over, "what the hell Stefan! Elena control your boyfriend."

"Stefan let her go." Elena spoke.

Stefan grabbed y/n and vamp sped to the Salvatore house.

Y/n was pushed on the floor and she stood up staring at him.

"Stay here. If I find out you took my brother. I'll kill you." He spoke walking away.

Y/n stood scared and terrified, she looked around for a weapon as Dean took hers.

*with dean*

"You said your a big brothers?" Caroline spoke to dean and Sam, "you take care of your little sister? Do anything for her?"

"Yeah we would." They both spoke.

"If you want her to live, you have to let Damon go or his brother will kill her. A sibling for a sibling." Caroline sighed.

Dean and Sam looked at each other and nodded.

They let Damon go and he stood up.

"You try to come after me again I'll kill her." Damon spoke.

"You make a move on her. You'll be dead before you hit the ground. You understand me? Do I make myself clear!?" Dean yelled.

"Understood." Damon glared.

They followed Damon to the house and they heard
Y/n scream.

Stefan walked out and they saw Sam and Dean and grabbed them throwing them into the cellar downstairs.

They heard y/n yelling.

"No! No! Please!" Y/n yelled.

"You hurt my sister I'll kill you I swear! I'll kill you all." Dean yelled at Damon, "I will kill you all!"

Caroline ran downstairs and saw Dean and sam trying to break the cellar door, it crashed down and they walked out.

"What's going on?" Caroline questioned.

"They have my sister." Sam walked past her and Caroline stopped Dean.

"They will kill you if you go up there." She spoke.

"She's my baby sister..." Dean walked away.

They got upstairs and they heard y/n scream and they ran in and saw Stefan feeding off of her.

Sam ran at Stefan tackling him and dean shot him a few times.

Y/n fell to the floor unconscious.

Stefan looked around and realized what was going on.

"Y/n!" Sam ran to her and grabbed her, "hey, hey wake up. Come on."

"What did you do to her?" dean yelled.

"I think I killed her..." Stefan dropped to his knees.

"Y/n! Come on! Wake up!" Sam yelled and started CPR.

"Dean! She's not waking up!" Sam cried.

"Oh my god." Jeremy ran over.

"She's human right?" Jeremy questioned.

"Yes!" They both yelled.

Jeremy took off his ring and placed it on her while Sam held her in his arms.

After an hour she woke up gasping and squirming.

"Is she okay? Is she okay?" Sam looked at Caroline.

Caroline looked at y/n,

"She's okay." Caroline sighed.

"He killed me. Stefan killed me." She spoke scared.

"Your okay." Sam held her.

"Y/n!" Dean ran over and held her.

*a few days later*

"We're leaving. We aren't staying in a town where my baby sister was almost murdered." Dean got in his car.

"Bye Elena." Sam nodded.

"Hey Sam. Here's my number." She handed him a paper and he nodded with a smile.

Y/n was talking to Jeremy.

"Y/n let's go." Dean spoke.

"Bye Jeremy." She smiled.

"Call me." He smiled back.

"Will do." She got in the car and they drove off.

"Watch your backs." Bonnie spoke to Stefan and Damon.

"Why?" They glared.

"I did some research on them. They're the best hunter in the world along with their dad. And an Angel named Castiel helping them. They've been hunting and killing demons way stronger than you two since they were kids." Caroline spoke.

"Oh great." They sighed.
