A/N okay so here I go, taking a crack at writing Daddy Dean, with a bit of a dark beginning in this fic, when Castiel is removing Lisa's memories, he discovers something that Lisa hasn't told anyone, she's pregnant. Pregnant with Dean's child, by the time Cas realizes this, it's too late, Lisa's memories are gone, but Ben's aren't so he makes Ben the child's protector. But keeps a close look over her till one day he doesn't and the unthinkable happens.

Disclaimer: I own nothing! well aside from Danny.

prologue

Ben looked up sharply as the man in the trench coat walked in, he spared only a glance in the direction of the boy, as he moved to Lisa Braeden's bedside, placing two fingers to her temple.

Ben sat up straighter, "What're you doing?" He asked, concern rising inside him for his mother.

The man looked back and Ben, and sighed, "I am helping a friend." He replied simply, turning back to Lisa, then he stopped, retracting his hand from her temple, "How is that possible?" He muttered, his hand dropping to Ben's mother's stomach, his eyes growing wide. He turned to Ben. "I'm sorry. It's too late, your mother will awaken and not remember a thing. But I will leave you." He turned and looked down at Lisa, "They will need protection. It is up to you now Ben."

Ben furrowed his brow, what the man was saying not quite sinking in. "What's up to me now?" Ben shot to his feet, "Who are you? What did you do to my mom? Dean!" he shouts.

The man hushed him, "My name is Castiel. I'm an angel of the lord, and I have locked away the memories your mother had of the supernatural world. Unfortunately, I cannot do the same with the supernatural world and your mother." The man turned and looked down at Lisa woefully, "I was supposed to lock away your memories as well, but with what I just sensed within your mother, that would be… unwise."

"What are you talking about?" Ben demanded.

Castiel turned piercing blue eyes on Ben, "Your mother is going to have a baby, and there will be things, demons most likely that will come for the child. It is up to you to be their protector. I will teach you all you must know, but then. Benjamin it is up to you, I cannot have a hand in the child's life beyond that."

Ben was about to argue, tell the man, who claimed to be an angel to make his mother remember and have Dean be all of their protectors, but something in the angel's gaze silenced him.

In one step Castiel closed the distance between him and Ben, and placed two fingers on his forehead, "When you waken, you will know all you need to protect your mother, and your unborn sibling from the forces of darkness." He told the boy, just before Ben's eyes flickered shut, and he slumped back down to the chair.

~~Danny~~

"Danny!" Ben called, "Olly, olly oxenfree" he stopped as he heard a muffled giggle from the closet down the hall. "Oh gee!" he sighed dramatically, "Where, oh where, could that Danny be?" he said as he approached the closet, his palm closed around the door handle, and he opened it, and looked inside, hearing another giggle from behind the coats. "Well I guess there's no Danny in here, but wait, I was looking for that spring coat of mine…" he said, pushing the coats aside, "well, well, well. What do we have here?" Ben asked, peering down at the small dark haired girl before him.

Danny giggled again, her green eyes glittering with excitement, "you finded me Benny Ben!" she cried using here little nickname for her older brother.

"Sure did angel bait!" Ben responded ruffling the child's hair, "But darn was it hard, I think you might be half chameleon!" he joked, swooping down, and lifting the squirming four year old out of the closet.

"What's a chameleon?" she asked her head tilting curiously.

Ben smiled, "it's a lizard." He told the tot.

Danny wrinkled her nose, "Ew!" she said, "I'm not a lizard!" she shook her head, whipping Ben in the face with her chocolate curls.

Ben couldn't help but laugh at her reaction. "No you sure aren't, but you are a little monkey!" he said, tickling her tummy, which made her giggle and kick at his side.

"Ben! Benny Ben stop!" she shrieked joyfully.

"Make me Angel Bait!" Ben challenged.

Danny started tickling his neck, and he fake squirmed to appease the young girl, as he backed into the living room and wrestled the little girl off of him, tossing her carefully onto the couch where she bounced twice and stopped, her giggling getting if possible higher. "Again!" she yelled, just as the doorbell rang.

"Sorry kid, man of the house duties." Ben said, turning to the door, as Danny threw one of the pillows from the couch after him.

Ben got to the door and opened it just a little, barely enough to see outside, and likewise for any outside to see inside. "Hello?" he asked.

Out on the porch stood a young man dressed in a smart suit, holding a pamphlet no doubt for some church in the area. "Hello! Have you heard the good news?" the boy started.

Ben sighed, "No I haven't, now I guess you're going to tell me." He said, trying to be clear in his disinterest for the subject.

"Why yes I am!" the boy said, "The good news is, the king has finally found just what he's been looking for, and he found it here with you!" he said chipperly as his eyes flickered to a straight black, and he kicked in the door, sending Ben sprawling to the floor.

"Now then right to business, where's the kid?" the demon asked grinning crookedly at Ben.

Ben clenched his jaw, and reached into his back pocket for the flask of holy water he always kept there, and flung the water at the demon, who screamed and fell back onto the rug, clutching his face, which smoked horribly, making the entry way reek of burning flesh.

"Why you little bastard!" the demon howled trying to come after the boy, but finding himself stuck in place.

Ben grinned, and flipped up the corner of the rug, revealing the devils trap etched into the floor.

Then he took off finding Danny huddling behind the couch, and lifting her into his arms, she latched onto his neck sobs wracking her tiny body, physically shaking with fear, "I got you angel bait." He whispered, running for the back door, and throwing it open, only to be met with another demon its eyes jet black.

"Where are you going?" he asked laughing, "The king hasn't even gotten here yet!" he spread his arms wide, "You can't leave before the party begins!"

"Omnis imundas spiritus." Ben started, but was cut off by a loud tsking behind him.

"Nuh uh uh, is that any way to treat your guests Benny Boy?" asked an all too familiar voice, the rough rasp that haunted his nightmares, "Oh, and this must be Squirrel junior. Aren't you a pretty one?"

Ben turned slowly, and his eyes met with the man who intruded his home, "Crowley." He choked, his hold tightening on his sister. He tried to back into the living room, to get to the door that led to the front of the house, but the other demon blocked his way.

'Cas, if you ever wanted to pop in, now would be the time.' Ben thought as the king of hell closed in on him and his sister.

Crowley waved a hand, and sent Ben into the wall, completely immobilizing him, "Not gonna lie. Thought this would be easier, because I was under the impression that Dean-O had all of your memories wiped by Casper the friendly angel, not that he gave you hunter juice to make you grow up big and strong." He said, reaching Ben, and taking hold of the frightened four year old.

"Hope you don't mind me taking this Benny Boy." He said, prying Danny from Ben's arms.

"You son of a bitch." Ben growled, "Leave her alone!"

"Sorry, kid." Crowley said, tickling the tot under the chin. A move which turned Ben's stomach, how dare that demon touch his sister! "I got big plans for little one." He told him, as he snapped his fingers, and the two demons with his sister vanished, and Ben slumped down onto the floor.

He failed. He had one job, one job that Castiel entrusted him with, and he failed. He lost his sister, who was his entire world, all because of Crowley.

Ben heard a scuffle in the front hall, and looked up, the demon in the suit was staring at him still trapped in the devil's trap, "Boo hoo the big bad demon took the baby. Get over it kid, hunters lose more than that every day you brat."

Ben felt white hot rage build up inside him, as he went to the coat closet and pulled out his one mode of defense that Castiel gave him five years ago. A long sleek knife, with a triangular blade, and rounded handle. Cas had promised it would kill anything that would come for Danny.

Ben growled as he charged the demon burying the knife deep into its chest. Watching as its eyes turned black then flashed a brilliant white as it died.

The demon fell from Ben's blade, and lie dead on the floor. He looked down at it in disgust, and wiped his face, dropping the knife, and falling to his knees. That's where Lisa found him not much later, a dead man in the hall and her baby girl gone from her life.
