Well, not many people read this soooo... :-/ IDK!!!!

Your eyebrows furrowed as you looked from Sam to Dean and back again. You were bewildered. "What do I need to explain to you? I had that hunt under control!" You swung your legs over the side of the bed and rose to your feet. Suddenly you became light-headed and sat down again. "Something about that doesn't seem like 'under control' to me!" Dean shouted, rolling his bright green eyes. "Well, excuussee me princess." you said sarcastically. Sam's concerned gaze darted in between the two of you.

"Was this the 'bad situation' then?" Dean asked accusingly.

"So? What if it was? Watcha' gonna do about it Winchester? Sam's not gonna do shit." you shrugged, raising your eyebrows as if to say 'what can you do?'.

There was an uncomfortable silence which Sam broke by saying apprehensively, "Am I missing something?" Both you and Dean turned to face him. "What do you mean Sammy?" you inquired. "Hey!" Dean shouted, "Only family can call him that!"

"Fine! Whadda ya mean Sammy?"

"[Y/N]!" Dean shouted again. You turned your head to face Dean. Your golden curls fell in strands over your face and down to your waist. Your [E/C] eyes pierced him. Suddenly, memories he didn't want to relive flashed before his eyes. Baking pies, throwing the ball in the yard... The fire.

"Yes Dean?" you asked in an icy tone, your eyes narrowed. Dean, however, stood his ground. No one messed with Sammy but him! "Did you hear what I said, [Y/N]?"

"Yes, and...?"

"Why aren't you listening to what I said?"

"I am!" you screamed, offended. Then you remembered he didn't know. Oh well, it was too late now. "Look," you said, attempting to calm yourself down, "you don't have to believe me, but John had another kid he didn't know about. Mary said she lost the baby to protect her daughter."

"From what?" Sam inquired. You stared up at Sam, bewildered. Fear danced like fire in your eyes. "Everything."

"Does that mean you're.." Dean began.

"Our.." Sam continued.

"Sister." you finished happily.

Sam and Dean stared at each other then gave you a why-should-we-believe-you look. Your expression turned solemn. "This is why." you said, as though reading their minds. You pulled a silver chain from around your neck.

You opened the silver pendent with a roughly carved Devil's Trap on the end to reveal two pictures; one, a family photo showing a young Dean holding Sammy, who had just come home from the hospital, with John and Mary next to him. The other one was merely a picture of a tall man with a scruffy grey beard and a trucker's cap.

"I almost lost it in the fire." you whispered breathlessly, "Mom put it around my neck when I was a week old..." you drifted off. "Oh, I may want to mention," you said, snapping quickly back to reality, "That I'm only three months younger than Sammy." you smiled shyly.

"Finally," Moose exclaimed, "a new youngest Winchester! Already trained, too!" Dean, however, did not take the matter as lightly. "W-Well hi.." Dean mumbled, the heat rising to his cheeks, slightly humiliated due to the fact that he had tried to hit on you earlier. "I'll forgive you this once Dean." you said with a smile and a giggle. Though Sam was younger and taller than Dean, Dean still towered over you. Why did you have to be so short?! It sucked ass.

Suddenly, you spoke, "Mind if I hunt with you for a while? I mean, after all, this is the family business."
