Why?

Steve Rodgers couldn't help but like S.H.I.E.L.D for its patterns. Alarms went off at exactly six am every morning, waking the entire S.H.I.E.L.D complex in Washington, D.C. Breakfast was served from exactly six am to seven am. Training, or mission prep, was from seven am till noon. Twelve until one was lunch, and after that Steve almost always went to explore the new world. From five pm to six pm was dinner. From that point on Steve would read, or try to figure out all the options on his cellphone. At ten pm, he would go to bed, and start the same routine in the morning.

The routine was what kept him sane in this crazy world.

Phone calls from Natasha at five thirty in the morning was another fairly regular thing. She would call from all around the world, craving some sort of human contact. She was mostly alone on missions since Clint had been taken from all field work duties, at least until he passed both his physical and psychiatric evaluations. He had been struggling with the psychiatric evaluation until recently, and had finally been released for field work.

This particular morning was no different. Natasha phoned, quickly telling him that there was a mission prep at seven am sharp, and that he better not be late. She hung up before he could get a word out of his mouth.

Mission preps always started on time. It was something S.H.I.E.L.D took pride in. The clock in room 212 had just past ten o'clock, and who ever was giving the mission plan still hadn't arrived. In the small room there were ten S.H.I.E.L.D agents, Steve, Natasha, and most surprisingly, Bruce Banner.

Bruce had arrived two hours late. He was wearing wrinkled grey dress shirt, and an equally wrinkled pair of black pants. His eyes had black bags beneath them. Black hair was sticking out in all directions. Bruce was practically chugging a large cup of coffee.

When he noticed both Natasha and Steve glancing at him with worry in their eyes, he gave a sheepish smile, "Sorry, I was put on a three o'clock flight from New York, which was delayed until five, this morning in order to get down here on time, or something like that. I can't sleep on planes."

Steve gently smiled at Bruce, "There's no reason to apologize. How have you been?"

"Great actually!" Sleep seemed to disappear from Bruce's eyes as he continued, "Living off of the streets has been great! Being able to take a shower everyday is something people seriously take from granted." Natasha and Steve couldn't help but to smile at their friend's happiness.

"Have you and Stark been working on any projects?" Natasha asked.

"Yes. We've been working on a prototype that can find life forms in space, so next time an attack happens we won't be so unprepared. It's been hard though since neither of us know much about space phys-" Bruce was cut off as Fury slammed the door open.

"Agents! This is a very important mission," Fury yelled, turning on the holo-screen at the front, "Lives are at serious risk if you fail!"

Fury pulled up the pictures of two men, "This is Samuel and Dean Winchester. Both men are high up on the S.H.I.E.L.D most dangerous list. They have committed acts such as murder, torture, grave desecration, and FBI impersonation. Reports say that the two feel justified in doing these things because of a new cult on the rise. A cult that they created."

"And why haven't we gone after these boys before?" Natasha asked, her voice taking a dark undertone.

"The Winchester's are smart. They keep themselves underground, only coming out to commit their crimes. Samuel has faked his death twice, using very similar bodies to his own. Dean has managed this feat three times, using the same methods as his brother. We finally managed to find them holding up in the small town of Lebanon, Kansas." Fury replied, anger evident in his voice.

Bruce took a deep breath, "Director Fury, not to be rude or anything, but this more of a case for the FBI or the CIA?"

"This has gone beyond those organizations," Fury stated with an uncharacteristic eye roll, "The cult that the two have started is beginning to gain members." With a flick of his hand, several new pictures showed up. Pointing to a middle aged man with windswept black hair, "This is Jimmy Novak. In 2010 he disappeared from his home. We believe this is when he decided to join the cult the Winchesters had created. There's a low chance that Novak's family was threatened." Fury swiped to the next picture, "This here is Kevin Tran. Honors student who decided to take a different path than college. His mother was killed by the Winchesters. He's young, but still very dangerous."

The next picture was a girl with long red hair," This is Celeste Middleton. She joined the Winchesters after years of breaking the law. These are the main five, but others have been in their tirade. Jody Mills, Ellen and Jo Harvelle, Ash Grommel, Bobby Singer, Lisa Braeden, Ben Braeden, and Amelia Richardson have also been seen with the Winchesters on more than one occasion."

"What do you want us to do?" Captain Rogers questioned.

"I want the two Winchesters back here alive. The Jimmy, Kevin, and Celeste are not top priority, but having them would definitely benefit us," Fury replied.

"What about the others?" Bruce questioned, sipping his coffee.

"When we take in the Winchesters, the rest of them should scatter. If not, we'll take them down as well. Besides," a small smirk appeared on Nicholas Fury's face, "Most of them are dead anyways."

The people in the room shifted, uncomfortable with the way their director had said that.

Natasha, being the first to recover, quickly took hold of the situation, "How are we playing this out?"

"You leave in 0500 hours tomorrow, Captain Rogers will be commander. Be ready and DO NOT KILL THEM," was Fury's final words before leaving.

"You guys waited there for three hours and he talked for less than fifteen minutes," Bruce commented, looking across the table at Steve and Natasha.

Natasha shook her head, " I make it my job to know everyone on S.H.I.E.L.D's wanted list, and these two have never been on it. You'd think that they would be somewhere on that list if they are as dangerous as Fury seems to think they are, even if they aren't Doom level."

"Director Fury said that they faked their deaths more than once. Maybe they recently showed up again, and that's why they weren't on the list?" Steve reasoned.

Natasha nodded, but the small frown on her face showed she wasn't quite convinced. The three Avengers sat in the cafeteria in silence, eating an early lunch.

"Why do you think all those people joined the Winchesters, I mean, none of them really looked like mass murders." Bruce said, eating a bit of his soup.

"There's a hundred different reasons Bruce," Nat replied, idly picking at her salad, "The Winchesters could have been a way out. A way out from dept, a way out from a boring life. Maybe they were threatened into joining. We just have to rust Fury, and get the job done so no one else gets hurt."

"The good news is I have a plan that should limit any sort of casualties," Steve announced, a smile on his face.

"So whats the plan Cap?"

That night, when Bruce went to bed, a million thoughts were spinning through his head.

The most prominent thought was that he was certain he had heard about the Winchesters. It was like a tickle at the back of his mind.

The Winchesters

Samuel and Dean Winchester.

Where had he heard those names? It was driving him crazy!

The second though that ran through his mind was what could possibly drive someone do those horrible things to someone?

Natasha had, at one point, done similar things, but she had a pretty good excuse. He honestly wondered if maybe it wasn't the Winchesters who had started this, but someone they loved. It was possible that their parents started it, and the brothers just followed what they did.

But that brought up more questions. Why did their parents start doing such terrible things? Did no one teach them how wrong murder was?

Bruce couldn't help but fall into an uneasy sleep that night.
