A/N-Like the last chapter, the first part of this one is a lot of conversation to move the story forward quickly to the huge changes to coming for Sam, Dean and their relationship.

…

After Cal and Dean's rough first encounter, it was a matter of building trust between them. Cal had a process in place for earning a new omegas trust. Most of them had been abused in some way so Cal looked for tells in their expressions, voice and body language. He got a good read on what Dean would and wouldn't tolerate. It was like being in the presence of a tamed lion, you needed to remember you were still working with an apex predator and avoid triggers.

Dean Winchester was so much more than a beautiful face on a bangin' body. The kid was a rebel, a fearless warrior, quick and smart and a heart so full of love that the recipient of that love would be a lucky person indeed. The things Dean had been through in his young life would have destroyed a lesser man. Cal saw all of this in him.

Dean was a perfect match for this particular mentor.

…

In the very beginning, Dean would leave the isolation and vanish for a day or two and sate all his desires then slink back to the cabin. That is until one morning he got back the cabin to find himself locked out. This was a test to see if the hard headed young omega was willing to tough it out and stay under his mentor's rules or would he leave out of anger and throw this chance away.

Dean chose to stay. He swallowed his pride and apologized to his mentor and showed Cal he was committed to the process.

There was a plenty of studying and lectures on omegas and their place throughout history. It was a roller-coaster ride of highs and lows depending on factors like leaders, war, disease, natural disasters and social discourse. Dean was surprised to learn there were omegas before him who took their brothers as mates and produced perfectly healthy offspring, thanks to omegas and their unique genetic makeup. Nature's failsafe to ensure the continuation of the human species.

As Cal was explaining this, Dean became very uncomfortable. He never told his mentor about his feelings for Sam and it was as if this man had entered the darkest reaches of his mind and found out every little secret. He was relieved when Cal moved on to something else. Dean just wasn't ready.

He often wished Sam was there, for many reasons but mainly because this was his baby brother's thing, books, history, research and the like. Sam could do it all and then give Dean the short version.

Things Dean deemed awesome and actually enjoyable during his stay there, was learning about the security setup for the cabin, the strategically placed trail cams in the forest, the false walls in the home, the weapons cache, the tunnel, how to make his own arrows, proper use of a bow staff and a crash course in Hapkido, the Korean martial art that incorporates a variety of weapons, including belts, ropes, and canes used in moves including kicks, joint locks, throws, and hand strikes to the body's pressure points. That was Dean's favorite. Cal was not a pacifist which only made Dean admire the man even more. That was another thing about Cal, he made no bones about omegas being men. The guy had long, shiny hair and wore clothes that he called tunics but Cal was a bad ass motherfucker and omegas were in the middle of a quiet war that Dean was glad to be a part of.

Dean missed Sam every single minute of every single day but he told himself he was doing this for his brother also. They spoke on the phone every week and it helped their situation that Sam was maturing and didn't hassle Dean for being gone so long. They'd parted ways both so confused, especially Sam, and the young alpha hoped if this helped Dean, it would help him in turn.

Nothing had changed for Sam, he still yearned for his brother's kisses and every night when Sam touched himself, Dean was always in the mix of fantasies. Sometimes they took a turn where Sam was the aggressor, those were the nights his orgasms were explosive. Later Sam would try to analyze those fantasies but there was really nothing to it, he wanted Dean in the worst possible way. As time went on, Sam found himself attracted to girls but he hadn't run across one yet who could hold a candle to Dean.

Sam's awkward shyness, respect for females and omegas, plus his love for his brother kept him pure as the driven snow.

…

The night Dean decided to reveal all his secrets, he picked the lock on the liquor cabinet and started on a bottle of something called Green Chartreuse.

"This tastes like crap…"

Next, he went for the Hennessey cognac.

"Yeah, for ceremonial use, my ass…"

When Cal returned, he found his charge drunk on a terrible blend of alcohol. Dean sat there on the couch with his legs spayed open and actually wearing one of the long tunics he was provided with.

"Oh Dean, not my Green Chartreuse."

"Relax, I only took a swig of it. Its gross, by the way."

Cal gathered up the bottles and put them away then made Dean a special tea in a tea bowl, "Drink this, it might help with that projectile vomit later. Dean, why did you do this, what set you off?"

Dean leaned forward and crooked his finger, "I'm gonna tell you what's wrong. Have you ever loved someone so much that what happens to you doesn't matter? Loved someone so deeply that a day doesn't pass by without him on your mind? I run away from him and I fill up my time with everything dangerous and bad because it's what I deserve."

"Go on Dean, just say it. Say his name."

"My Sammy my Sam my baby boy my brother."

Dean waited for his mentor's look of disgust or surprise but Cal's calm expression never wavered. It was a little disappointing in fact because Dean was counting on getting scolded. It would make it so much easier to leave Sam alone if this relative stranger passed judgement on him.

"Your words are raw and real and the love you feel for Sam is evident from the tears in your eyes to the pain in your voice. I know you're looking for some sort of answer. I can tell you this, you won't be the first omega to fall in love with his brother and you won't be the last. We talked about this, Dean. Its ok."

"My dad would kill me if he ever found out. He thinks he fuckin' owns me or something. Bobby would be so disappointed in me. I don't wanna lose Sam."

"I promise, things will work out," Cal tapped his forehead, "I've seen it."

Dean scoffed, "I don't believe in dreams, visions or psychics or any fortune telling garbage."

"But yet you've battled witches and werewolves, vampires and ghosts and any host of things. I've heard things about your brother Sam, that he has certain gifts. Don't worry Dean, I'm very discreet and your brother's secret is safe with me. I had a vision of an older Sam writing in a journal and there were children's drawings taped to the wall."

Dean swallowed hard and then downed the bowl of tea. "Sounds about right. Since he was a kid, Sam has done drawings from his dreams. I doubt he'd hang them up though." He let out a sigh, "Weird."

Cal switched gears, "Do you know the world will go through catastrophic changes? Between the couplings of fiendish creatures and the willful damage we've caused over millennia, humanity will be brought to its knees. Sick, rage filled creatures will roam the earth, predators who are no more human than a snake or a bear."

His mentor suddenly stopped and Dean watched as the man's eyes blinked rapidly, opened wide then went back to normal.

"Hey, are you ok?"

The omega elder smiled at him, "What was I talking about again? Oh, I wanted to show you something. He sat next to Dean and handed him a photo of a handsome young man holding the hand of a cute little girl with a big gap smile with missing baby teeth.

"Cute kid."

"This is my brother and our daughter Fara."

Dean's eyes opened wide, "Wow, that's awesome, where are they?"

Cal's whole demeanor changed, "A car accident years ago…they didn't make it."

Dean put an arm around his shoulders, "I'm so sorry, man."

"Hold on to those most dear to you because life is uncertain. Hold onto Sam."

…

The next morning they had their last breakfast together at the top of the ridge where they shared a thermos of coffee and some muffins while enjoying the view of the valley below and the first hints of autumn colors.

"I'm leaving today."

"I know."

"But I just decided this morning! How did you-never mind."

Cal smirked, "I saw you packing."

"Ha! Ok."

"I left you some boxes in the back seat and the keys to my kingdom."

"Uh, what does that mean exactly?"

Now you see how fortuitous this was, us meeting. You are an incredible young man Dean Winchester."

"I don't know how to thank you for everything, Cal."

"You and your brother survive and thrive no matter what the world sends your way and that will be my thanks." He nudged Dean, "Also please take all those clothes I gave you. Maybe Sam or Bobby would like to rock a tunic."

Dean cracked a smile and laughed, "I know Sam will wear one. Who knows, maybe I'll use them for pajamas."

"Don't for there is a special, dressy one in there you can swan around in on your important day."

"Yeah, and what day would that be?"

"You'll know it when the opportunity comes."

"Dude, you are so weird."

"Birds of the feather."

….

The sound of his feet rhythmically hitting the pavement and Rumsfeld's panting as the dog ran alongside his human, put Sam in a calm, steady state of mind. A rush of endorphins spurred him on just a little farther.

"Scrambled eggs and fruit when I get back…nah, that requires cooking…cereal, fruity O's…"

Sam made a U turn and headed back toward home and Rumsfeld was right beside him. "Come on Rums, you can do it!"

The dog stopped in his tracks and let out a throaty growl. A man appeared at the edge of the woods, then shambled up the ditch and onto the road. Rumsfeld looked up at Sam then back to the stranger. He started barking like mad, teeth gnashing and hackles up.

"Come on Rumsfeld, it's just some guy."

Sam waved to the stranger who was some distance away and walked to the opposite side of the road, "Come on fella, time to go home." The rottweiler went quiet as he eyed the dangerous thing ahead. He would protect his boy at all costs. Rumsfeld charged just as it charged Sam. Sam scrambled for a rock to stop what he could now see was something not human. Rumsfeld launched himself through the air and knocked it on its back, the dog clamped down on a forearm but this monster in melted human skin suit, sunk its teeth into the dog's meaty neck.

Sam lifted the large rock and with all his strength, brought it down on its skull again and again until it released the dog's neck. Rumsfeld was prone in the grass, letting out a wet, wheezing sound. Sam ran as fast as possible back home for help.

…..

Bobby stood when the vet entered the waiting room. By the look on her face, Bobby knew it wasn't good news.

"How's my dog, Doc?"

"Come on back, Bobby."

He found Rumsfeld on an old blanket with chest heaving and strangled sounds coming from his throat. Bobby crouched down and stroked the dog's sleek fur, "I'm so sorry boy, yah don't deserve this."

"It's very bad I'm afraid. There isn't anything to be done, Bobby." She placed her hand on the man's shoulder.

Bobby sat on the floor next to Rumsfeld, "Go ahead, I don't want him suffering anymore. Goodbye, good boy, goodbye."

…..

Dean was almost there with Singer Salvage in his sight and then he saw the flames as he got closer, licking the sky and the musky smell of smoke and pine needles filled the cabin of the car through the open windows.
