A/N: Here's my Daddy!Sam fic! This is for Sammy's Wolf Girl because I promised her I'd get it out!

Disclaimer: I don't own any of this- I just like fuckin' around with the boys and my OC's.

Warning: Umh… I fill this part in later…

I'm writing out the episodes with my OC in them!

"You did it, Sam." Ruby said, reaching out towards Sam Winchester.

"What? What did I do, Ruby?" Sam asked, panicking.

"You set him free. You set Lucifer free. Now we can go to Vixen and take care of her together." Sam reeled backwards. Vixen? That child Ruby was always talking about? She was alive in this time period?

"Wha- What?" Sam asked, dumbfounded.

Ruby grinned at him, "Vixen Mary Winchester is half you-" Her grin widened, "half Samhain."

Sam's jaw dropped and he felt his knees start to shake, "Vixen is mine?" He asked, bewildered. He'd only seen a couple pictures of Vixen so he knew what she looked like and his brain couldn't process that- yes, she looked like him… too much like him.

But, she was part Samhain. She was part demon. Sam felt sick. His stomach churned and gurgled and he felt like he was going to throw up. Dazedly, he slumped against the cold concrete wall and watched Ruby as she knelt in front of him, "She takes after you, Sam. She's a good kid, she just wants her daddy."

Sam shoved weakly at Ruby but she caressed his cheek and kissed his lips, "We'll take care of her- just you and me." Suddenly, the doors crashed open and Dean rushed through.

"I don't think so, bitch." Dean growled, plunging the knife deep into Ruby's chest. He twisted it and watched her demonic essence spark and stutter out. Sam crawled over to Ruby and shook her lifeless body violently.

"Where is she? Where's Vixen?" Sam screamed, pounding his fists into the concrete floor. Dean grunted as he dragged Sam to his feet.

"Sam, we gotta go." Dean huffed; his entire body was taut from the adrenaline that rushed through his system. But Sam was frozen. His gaze was fixed on the growing light that was pouring from the floor.

"He's coming," Sam panted, a tightening in his chest flooded him with a nauseating warmth. He wanted to go to it, but he knew that it was Lucifer and the fact that he didn't care made him sick. He gripped Dean's jacket with wide eyes.

"We gotta go!" Dean growled, pulling Sam towards the doors. They swung shut just as they reached them, "Son of a bitch!" Dean shouted, pounding on the oak once before cringing at the high pitched ringing sound. He and Sam fell to their knees as the shrill squealing became unbearable.

Then, it all stopped. The ringing, the pain, the burning light… everything. It all just… stopped. Sam blinked in confusion and pulled himself upright into his seat. A small, child-like giggle alerted him to the fact that there was someone next to him.

"Vixen!" Sam said with so much emotion that the little girl just blinked at him. Her skin was paler than porcelain, her lips were plump, cupid-bow pink, her eyes were neon purple with a ring of hazel around the pupil and her hair was a shock of black. She seemed to be just around ten months old.

Sam knew that wasn't true. Ruby had told him she really was only five months old but 'her kind' grew quicker than humans. Now Sam knew that 'her kind' meant half demons. He blinked for a half a second before he could even react.

He scooped her up into his arms and simply held her. As of now- it didn't matter that she was half demon, Sam was going to take care of her. If he wanted her to ever be safe and good he would have to try to show her.

Dean was sitting next to Sam, hyperventilating slightly. Sam placed a gentle hand on Dean's shoulder and gave him a shaky smile, "We're good for now, right?" Dean blinked, swallowed hard, and nodded.

"I think so, Sammy." Vixen reached out towards him, making an impatient noise. Dean frowned at her, "Umh, Sam, you wanna tell me where the munchkin came from?"

Sam blinked, how the Hell was he going to explain this? Vixen patted Sam's neck and he smiled down at her. She was staring up at him with an innocent look on her face, "Dean, this is your niece." Without another word he placed Vixen into Dean's lap and waited for the reaction.

"Niece?" Dean gawked at the girl. She swayed on his lap and before Sam could reach out and stabilize her Dean beat him to the punch. A grin spread across his face when she cooed and leaned into his chest, "I guess you really aren't a virgin, eh Sammy-Boy?"

Sam snorted a laugh and was just about to retort when the overhead speakers came on, "Folks, quick word from the flight deck. We're just passing over Ilchester, then Ellicott City, on our initial descent into Baltimore-"

"Ilchester, weren't we just in Ilchester?" Dean asked, glancing out the window for a quick second before gripping the armrest and forcing his gaze back onto the little girl in his lap.

"So if you'd like to stretch your legs, now would be a good time to-" Before the pilot could finish, a huge beam of stinging white light erupted from the ground below and the shockwave hit the plane, "Holy crap!" was the terrified shout as the plane trembled.

Dean hugged Vixen while Sam tried to get the oxygen mask on her face. He placed one of Dean's face and then his as the plane rushed towards the ground. Sam prayed with all his might that the three of them would be alright.

Dean was still shaking as he drove in a rented car- rented; it was not his baby- with Sam and his niece. They had to find Chuck and just lay low until they could figure this crap out.
