Dean sat in the bunker absently scratching at Cain's Mark. The more he looked at it the more he wished he could get a branding iron and burn it off. Sam walked in, a towel in hand, scrubbing at his wet hair. He sat down across from Dean and raised an eyebrow. "Oi, Dean you okay?" Dean stopped and looked up. "Yeh, I'm good. So we got a case or what?" Sam didn't say anything but his face made it clear that he didn't believe Dean. "Um yeh," He dragged the laptop towards him and powered it on reading the research he had been doing the night before, "We got a possible ghost problem in Lincoln, and there's a bunch of people going missing in Topeka, but haven't found anything to suggest it's our field."
Dean was itching to hunt, and the way he kept looking at the Mark had Sam worried, he needed to find a case for Dean. If Dean needed to help people to deal with the mark, then Sam would do everything in his power to help his brother deal with it, until Sam and Cas's research came up with a cure. Dean leaned back in his chair for a second and then with a sigh he stood up, "Well, I'll fry up some breakfast and you see what's up in Topeka." Sam nodded and turned his attention back to the screen, his long hair flopping in front of his face. Dean snorted, his brother was such a geek. He turned to walk towards the kitchen when the sound of wings signalled the arrival of Castiel right infront of Dean. "Cas?!" This time he wasn't alone, his hand lay on the shoulder of a young teenage girl and from the way she was swaying and the blood running down her face she was not in good shape. With a groan the girl began to pitch forward and Dean instinctively stepped forward to catch her. "Crap! Cas what the hell?"

Cas's face remained impassive. "Protect her, I will return."
"Wait! Cas! Cas!" but it was too late, Cas had already Scottied out. Dean shook his head, "Friggin great." Shifting the weight of the unconscious girl he swung her up into his arms, she moaned a little but didn't wake. Dean turned with the girl in his arms, Sam sat there with a completely bemused look on his face. "I… don't… just What?" Dean just rolled his eyes, and headed towards the bedrooms, approaching the empty room next to his own where Charlie usually stayed and placed her gently on the bed. Sam followed in with a wet cloth and the first aid kit, and sat on the edge of the bed and gently started wiping away the blood, his other hand moving the hair off her face and trying to discover the source of the blood.

"Who do you think she is?" Sam asked. Dean snorted, "No freaking clue! I can't believe Cas just dropped some random chick here. Cas! You get your feathered ass down here and explain!" Dean took a moment to take a look at her; she had shoulder length light brown hair and couldn't have been older than 16 or 17. "Hey Dean, check this out." Sam was pointing at a silver charm bracelet round the girl's wrist. Dean did a double take, the charms were a mix of protective symbols, including anti-possession and a Men-of-Letters symbol; it looked nearly identical to the one past-Mom had been wearing when he'd been McFlyed to the past. "She's a hunter, or from a hunter family."

Dean scrubbed his face with his hand, this was just awesome. If Cas had kidnapped a hunter's kid there was going to be hell and Cas would only do it if some serious crap was going down.

As Sam reached forward to place a Band-Aid over the cut near her hairline a hand shot out and grabbed his wrist. Sam started, and looked down; the girl's eyes were open and staring at Sam. Her eyes widened and flicked to Dean, then to a spot just behind Dean's shoulder, and she let out a gasp and struggled to move further up the bed. Dean whirled around and nearly collided with Cas, who stepped around him and then strode forward towards to girl, who had let go of Sam's arm and was now trying to get off the bed but Sam was holding onto her shoulders. "Calm down, you're injured, you might have a concussion. No one is going to hurt you here."

Sam hadn't noticed Cas until the angel leaned down and placed two fingers on the girls head, who's eyes rolled and she slumped unconscious.

Silence filled the room and Cas and Dean stood awkwardly looking at each other while Sam placed the girl on a more comfortable position on the bed.

Dean narrowed his eyes, "Explain Cas, Now."

Another Bunker… Another Time… 1999

"Dean Winchester! How many times do I have to tell you not to leave your shows lying around!" Rose grumbled as she picked herself off of the floor, grabbing Dean's muddy boots she hurled them into the corner. "Jerk is getting Nair in his shampoo again." She muttered darkly. She sighed, surveing the mess that covered the library desk, and began to clean up. Sorting out all the research they'd done over the last couple of nights. One paper stuck out to her, in all it's un-supernaturally way and she grabbed it. Reading the title she smirked and began to leaf through it. "Rose!" Sam came running into the library, he had his book bag flung over one shoulder and a rolled up pancake in his hand. "My English paper! I can't find it… Have you seen it?! It's due first period and all I have in my bag is my research on Poltergeists!" As Sam continued to 'flap' hysterically around the room, Rose just lifted the paper out in front of her and waited patiently as Sam rambled on. "Dean might be messing with me again. Like that time he swapped out my show-and-tell in fourth grade, or the time he filled my pencil case with rock salt or the time he…" Sam caught sight of her and his paper and sighed in relief. "Gee, thanks Sis for letting me run round like a freak!"

"What else are sisters for? And we're all freaks Sammy so nothing new there."

"Got to go, Dad's heading into town anyways so he's giving me a ride. See you after your free period! And you're still coming to my game tonight right?!" He shouted over his shoulder as he ran out the door.

"Wouldn't miss it!"

Dean entered still in his sweats and with sleep tousled hair, his hand coming up to cover a yawn. Catching sight of her he grinned, "Morning Midge"

Rose scowled. "Don't call me that!"

"Why not Flower Power? You're the midget of this family."

Rose sighed, "I'd almost kill for the days you called me Rosie Posy."

Dean smirked and twerked one of her plaits in a sign of affection, she responded my sticking her tongue out at him.

"Jerk."

"Bitch." He replied easily. "Breakfast?"

"Yeh there's a stack of pancakes next to the stove to heat up, or there's left over batter in the fridge if you want to make some fresh ones."

"Chocolate chip?"

"And blueberry… duh!"

"Ever told you what an awesome little sister you are? Even for a midget pain in the ass."

Rose whacked him upside the head but grinned.

After breakfast Rose pinned her plaits up to her head and tied a blue bandana around her head, while Dean continued to read the magazine he had hiding behind his book on Demon Lore, which he thought she hadn't noticed.

"Right," she said scooping up her backpack, "I'm off. Don't forget Sam's soccer game this afternoon. I got off work so we could both go."

Dean nodded, then put down his book with a sigh. "I'll walk you. Got nothing better to do."

Rose raised an eyebrow but didn't say anything. Even if there hadn't been research to do, Dean would have insisted he take her anyway, part of the annoying overprotective big brother role.

He simply raised an eyebrow in return and reached up to grab his jacket. Dean watched Rose as she tied the shoelaces on her converses and smiled reminiscently remembering teaching her to do that when she was a kid.

"Okay, Let's go then big bro." Dean grinned, and without saying a word took her backpack off her as they left the bunker.

As they walked down the street towards her school Dean and Rose continued to banter, Rose shoving into Dean to make a point. He made a point of stepping on her laces and undoing them so she promptly tripped. He laughed and she glared but knelt down to redo them as Dean continued to walk.

The air began to shift, and the wind began to blow wisps of hair back into Rose's face. She looked up confused as a chill ran down her spine. The wind was swirling around her and her brother, the clouds growing darker. She gasped and Dean whipped round. "Rosie! Look out!" The hair on the back of her neck stood on end. She turned, a woman stood there, long red hair flapping and a long dagger in her hand. She was chanting in a language Rose did not recognise and before she could raise a hand to defend herself the woman struck Rose with the base of the dagger on her temple and Rose felt herself drop like a stone. "Rosie! No! Let her go you son of a bitch!"

Rose's head was throbbing; she could just make out the chanting and Dean's cries. She desperately to reassure him but she couldn't seem to get her body to coordinate her demands and as the cries intensified and the wind swirled and all she could see was swirling grey and black and flashes of light the edges of her vision began to blur and just as she lost her fight for consciousness she managed one final plea. "DEEEAAAANNNN!"

"RROOOSSSIIIEEE!"

Disclaimer: I do not own Supernatural or any of their characters... apart from Rose who is my own brainchild. I wish I did but Warner Brother's got to them first... Damn It.

Please Review!

This is my first Supernatural Fanficton. I've read a lot of sibling fics and hate how they dominate the story so will try and focus on the brothers, but I wanted to see a comparison if there were more women in their lives so this idea popped into my head. Hope you enjoy it!
