The Power of Two:

"Dad?" Sam and Dean repeated, incredulous.

Nathan furrowed his brows as he looked at the two men before he looked at Bobby, who had his eyes squeezed tight.

"Dad? Who are these people?" Nathan asked, narrowing his eyes at Dean and Sam.

"Balls!" Bobby cursed again, louder this time as he looked up. "I knew this was going to happen one day, just not today."

"Bobby, what the hell is going on?" Dean finally spoke, furrowing the brows at the guy that kept calling Bobby dad.

Bobby let out an explosive breath as he recapped his head. "Dean, Sam, this is my son, Nathan, your brother."

"What?!" the three of them chorused this time, all turning to Bobby.

Bobby didn't say anything more and instead turned, going to sit at his desk. He pulled out a bottle of amber liquid and pored some into a glass before he drank it in a few swallows. Dean, Nathan and Sam fallowed him; Nathan and the Winchesters sending each other suspicious glances.

"Dad, what are you talking about?" Nathan asked softly, confused; he was an only child and if Bobby said that these two were his brother, than they were Bobby's sons too.

Bobby finally looked up. "Why don't you take a seat, boys?"

For a second they didn't move and then at the same time they all took action; quickly finding a seat. Dean and Nathan took the chairs that were across from Bobby, while Sam took a seat on the cot by the wall. All three looked at Bobby expectantly, demanding answers.

Bobby let out another sigh before he looked at Nathan. "Nathan, you are my son, we just aren't related by blood."

"But—" Nathan started, but didn't finish; what could he really say to that, all he felt was hurt—Bobby had been lying to him all this time, and what of it was the truth and what was a lie.

"There's nothing to be but-ing about, you are still my son whose diapers I changed and tucked in at night." Bobby told him firmly, a softness in his eyes that only a son could bring out in a father.

Dean looked between the two of them, never seeing Bobby like this before, despite the fact that he thought of the brothers as sons too. Dean didn't know what to think about that—hell, he didn't know what to think about anything at the moment. How could John have another son—again—and not tell them all this time; and Bobby, knowing about it, raising said kid and never telling them all this time? Dean shook his head, he better pay attention because there was no way that he was going to go through this again.

"What about mom?" Nathan asked, for the moment ignoring the Winchesters; right now he just wanted to know the truth, to know that his whole life hadn't been a complete lie.

"Angela Singer was not your mother, she died a year before I got you by Demon possession." Bobby said, looking down at his hands briefly at the reminder of his beloved wife and how he had gotten into the Hunting business in the first place.

"Then who is?" Nathan asked, his voice hard.

Now it did make sense why he didn't feel that mother-son connection between them, despite the fact that he had only seen pictures of her—and never ones were she was pregnant, he now realized. But he thought of her as his mother and thought that that was where he had gotten his dark hair and his emerald eyes—but that had just been a lie too—one, he realized, of many that were to come.

"Mary Winchester," Bobby said, this time looking between Dean and Sam before he turned back to Nathan. "And your real father was John Winchester; both Dean and Sam's parents."

"How is this possible?" Sam asked; confused more than anything.

"When your guys' mother first became pregnant, that was with Dean and then the realized that they were having twins." Dean and Nathan's eyes snapped to each other at that, looking each other up and down, noting the sameness in their features, hair colour and eyes—the weren't identical twins, but they were paternal twins either.

Bobby continued, "They were just starting out, just getting their life started and they realized that they wouldn't be able to take care of the two of you; they just weren't ready." Bobby looked between the two of them, wanting them to understand this. "They did want to give one away to the adoption agency on the chance that you'd be left there. John and me had known each other for years, we worked with each other and were friends; so I adopted you Nathan." he now only stared at his son. "Not only because John asked me to, but because I wanted to; the minute I held you in my arms I knew that you were *my son."

Nathan was silent as he looked at his father, yes, this was his father; the one that raised him and took care of him, not this John Winchester who just happened to be the owner of the sperm that created him. He would always think of Bobby as his father, not matter what happened tonight—despite the fact that they were not related by blood.

Dean took the silence as his chance to speak. "If he's our brother, then why did we just find about this now?" he demanded.

"Afterward, when your parents finally got themselves together, you were four and Mary was pregnant with Sam. They wanted Nathan back, but I wouldn't have it, he wasn't some pet cat that you can get back if change your mind; he was my son." Bobby said firmly. "After your mother died, your father stayed here for awhile while he sorted things out and I made him promise not tot say a word to Nathan. Then he turned the obsession of hunting the Yellow-Eyed Demon onto you and Sam, he wanted Nathan too, but I refused it. I tried to get your father to change his mind about the two of you boys, but he was bull-headed." Bobby shook his head.

Dean hated the fact that he had been lied to; especially as something as big as the fact that he had another brother—a twin at that—and that he had been here the whole time, all around him. Probably only an arms length away every time he and Sam had come to the Salvage Yard. And maybe he was even a little jealous of Nathan, but he was never going admit it to anyone.

"I did agree, however, that I would tell Nathan about the Supernatural when he was the right age and able to make the decision on whether or not he wanted to be a Hunter instead of forcing it on him like your father did to you two bone-heads." Bobby sighed.

Okay, so now Dean was definitely possibly envious—he and Sam had never really had a chance to choose whether this is what they wanted to do; John did force it on them, this is what they grew up with and was what they had been fashioned into. Hunting was sewn into their life-lines, Sam had tried to get out with little success, the Yellow-Eyed Demon haven fallowed him to Harvard. Dean gave a silent sigh as he ran his fingers through his locks and he and Sam shared a look.

"Why did you try so hard to hide him," Dean glanced at Nathan, still not sure what he felt about the other man. "Even he knew about all this shit, you didn't have to hide him—even if we did meet, you wouldn't have to spill the beans."

"You mean like now?" Bobby retorted. "No offence, but you bone-heads drag the Hunting life with you no matter what; like it's your frigin' girlfriend." the three boys raised their brows at the same time at the comparison. "What would be the point of Nathan not choosing that life if it hangs around you guys? I've been trying to protect him from these things for his entire life, and to have all that hard work blown because of a simple 'hello'?" Bobby shook his head. "And now with all this Angels VS Devil crap flying around..."

Nathan's brows shot up at that; Angels and the Devil? This was news to him. He vaguely knew about Ghosts and Vampires and Werewolves and Shape Shifters and all that crap—all the Monsters of the world—but Angels and the Devil; Heaven and Hell stuff? Bobby had told him when he was about sixteen, and Nathan had read all the books and crap, but despite the seriousness in his father's voice and face, he couldn't really believe it, think that it was true—if he saw it face to face, then yeah...that'd be real enough for him to believe, but until then it was all still just a fairy tail.

"Now what?" Sam asked, still trying to wrap his head around the fact that they had yet another brother, and said another brother was Dean's twin.

"Now you guys should probably chat." Bobby said, knowing that whether they wanted to or not, it should be done. He looked at Nathan long and hard, making sure that his son was okay because he knew that this was going to be the hardest on him. Before he stood, "I'll let you boys get to it."

Though before he could move, there was the gust of wind and the sound of wings and Castiel appeared behind Dean and Nathan in a whirlwind of tan coat-tails.
