Summary: The Heroes have always been able to do the most impossible missions, but when two strangers, Sam and Dean, arrive, things aren't just impossible, they are chaotic.

Colonel Hogan was in the barracks like usual, but everyone was sound asleep, but for some unexplainable reason, he couldn't. He didn't understand why, but he had a terrible sickening feeling, settling in his stomach, making sleep almost impossible. It was like anticipating something bad before it happened. But what could be causing this strange feeling?

He sighed, and sat down at the small brown table in the main room, just staring at his men. They all seemed to be sleeping peacefully, and like usual LeBeau had thrown the covers off himself.

Hogan suppressed a laugh and went over and covered him back up. He started heading back to his office, only to stop about halfway, when the barracks door opened to reveal Sergeant Schultz.

"Inspection again, Schultz?" Hogan asked.

Startled by Hogan's voice, Schultz beamed the flashlight right into Hogan's eyes, causing him to put up a hand to shield, the brightness of it.

"Schultz, please put down the flashlight."

"Oh, it's you, Colonel Hogan; you startled me for a second… Why are you not in bed?"

Hogan rubbed his eyes. "Couldn't sleep, Schultz."

The sergeant could see uneasiness etched on the Colonel's face. "Is something wrong?"

Hogan shook his head. "No. But I think I'll try and get some sleep now."

Schultz nodded, watching as Hogan disappeared into the office, shutting the door behind him. He shone the flashlight around, making sure all the men were there, before walking back out into the cold night.

A white light exploded, and two men stood just beyond the woods of Stalag 13, arguing loudly about something.

"I told you that hunt wasn't a ghoul, but you wouldn't listen, and now look what it did to us," Sam said.

"Okay, smart-ass, if it wasn't a ghoul, then what the hell was it?" Dean asked, staring at his brother, seeing the irritation in his hazel eyes, and the dark circle under his eyes. It had been weeks since the Miller case, and it occurred to Dean that Sam was getting less and less sleep, and instead he was waking up with constant nightmares not to mention the premonitions Sam had to deal with both night and waking hours.

"How should I know? You're the one who wouldn't let me do any research."

"Yeah, well, excuse me, for letting you get your beauty sleep, Sammy."

"It's Sam. I am grateful you let me get some rest, but, you overlook the most obvious things sometimes, mainly because all you do on my laptop is watch porn."

"Hey! That hurts, while you were off at school, I had to do all the research myself."

"Yeah, okay. Whatever." Sam was too tired to argue anymore, since it was getting nowhere. "So, what do we do now, Dean?"

"How should I know?" Dean asked. "You're the brainiac."

Sam rubbed his eyes, and sighed, but before he could reply footsteps crunching into the ground, alerted both brothers, and they positioned themselves, waiting for the attacker—or attackers. And that's when a guy in a black leather jacket with a tan uniform shirt underneath, brown slacks, and a brown hat, stepped out.

Dean grabbed his gun and pointed it at him.

Hogan froze, holding up his hands. "Whoa, hey, I'm an American; I came out here because you guys are going to get captured if you don't come with me."

Sam looked at the man, and he didn't get any bad feelings; he came to realize that they could trust this guy, and turned to Dean, pushing the gun down. "Dean, I think we can trust him."

Dean placed his gun back behind his back, his jacket covering it. "Fine, but I swear to god, Sam, if you're wrong, I'll shoot." Sam nodded.

"Look, let's get you guys into the tunnel, before the Germans come."

"Germans?" Dean and Sam asked in unison.

Hogan nodded. "No time to explain just follow me."

They followed him to a spot, watching as he removed trees and lifted up a trap door in the dirt.

"Get in!" he ordered a whisper.

The brother each looked at each other, before they went down, Dean first, then Sam, then Colonel Hogan. The underground tunnels were absolutely fantastic. Sam's eyes scanned them. There was a money printing station, and much other cool stuff.

"What is this place?" Dean asked, taking in the same fascination as his little brother.

"This is the underground, we help get people in and out of Germany and help the allies."

"Dean, do you know what year we're in?" Sam asked, and Dean turned to see the surprise in his brother's eyes.

"No, but let me guess, you know."

"We are in 1940." Dean looked at him dumbly. "Dude, seriously? We are in the time of WWII."

Dean's eyes lit up with a Son of a bitch look, and Sam understood it. "How do we get back to our time, Sam?"

Sam shrugged. "I don't know, but it's your imperfection that got us into this predicament in the first place, and until I come across a solution to our current situation we can't leave this place."

"Big words, Sammy."

"Translation: It's your fault we are in this situation, you big jerk, and until I figure out a way to get us back, we are stuck here." Sam then smiled brightly and looked at Dean. "Do you know what that means?" Dean shook his head. "It means, you won't get to see your car."

Dean's eyes went wide with fear and sadness. "Oh, son of bitch! Not my baby, not my impala," he sobbed.

Sam couldn't help but laugh.

"It's not fucking funny, Sam!"

Colonel Hogan was staring at them intrigued, yet very confused at what they were talking about, but decided to drop the subject, considering that they were making way too much noise.

"Guys, hate to break it to you, but you need to tone it down, if Commandant Klink hears us, our whole operation could go right down the drain, because of two loud mouths."

"Sorry," Sam apologized, feeling guilty.

Dean just nodded. "So, what's your name?"

"Colonel Robert E. Hogan, but you can just call me Hogan, but will settle with getting to know each other later. Right now, you guys will have to stay down here, until we can get you into Stalag 13 without you having to live down here forever. But that will all be handled in the morning, right now, we sleep. There are two chairs down here, you can use to sleep," Colonel Hogan said, as he started going up the latter, only Dean stopped him.

"Hey, hold up a second."

"I don't want to have to order you if I don't have to, so please, feel free to settle in, everything will be sorted out tomorrow. Oh, Klink will be in for a surprise tomorrow," Hogan mumbled to himself, smiling as he headed upstairs. Thankfully, they made another entrance, for emergencies.

After he disappeared up the ladder, Sam and Dean were alone.

"So, what do we do now, Dean?" Sam asked, and Dean couldn't help but smile as Sam sounded like the scrawny five-year-old that always looked up to his brother for the answers.

"Well, for one thing Sam, we get some sleep, because let me tell you little bro, you look like crap, and are practically dead on your feet."

"Dean, I'm worried." Sam said, and Dean detected the uneasiness easily in Sam's voice, whatever was going on inside his little brother's head was enough to worry Dean. Sam rarely would admit anything, usually keeping secrets to himself.

"Why's that Sam?" Dean asked, as he led them both to the two brown chairs that Colonel Hogan mentioned, and planted Sam down, covering him as he pushed the lever back, but with Sam's gigantic frame, his feet and some of his legs were hanging off.

"What if something were to happen? I mean this place doesn't exactly scream out supernatural."

"You do have a point Sam, but with our luck, supernatural things are just around the corner."

"I wish you hadn't put it like that," Sam said with a yawn.

The next morning, Hogan briefed his men on the two strangers down in the underground and about the situation, he'd come up with a plan for them to sneak in but he needed to be exact, he couldn't afford to make a mistake and lose these two, something about them, had Colonel Hogan's nerves in a bind. He knew deep down he could trust them, but after-all he still felt the urge to get many answers to many unanswered ones.

At roll call, Hogan brought up Sam and Dean tells them to wait in the woods until Hogan yelled, he sent two of his men with them, of course, it wasn't two of the heroes, but it was two others that rarely helped them out. Unfortunately, Klink was not in a good mood, he put the two men that escaped in the cooler for thirty days, while Sam and Dean were sent into his office; thank goodness Hogan's men gave them each a fake name, rank, and serial number, but they couldn't exactly explain the clothing, but like usual Hogan helped sort that out.

"Are you sure these men are sergeants, Hogan?"

"Of course, I'm sure. I've worked with these men at base camp in America."

"I don't know, Hogan, they seem very unusual."

"Well, that's because, and I don't have to tell you, that they are undercover."

"Undercover?" Klink asked, surprised, but then frowned. "For what?"

"Don't you know? They were the two new prisoners your men shot down in that air raid."

"Really? Interesting. But Hogan, how can I be sure these men aren't here to spy on me?"

"Do, you really think they would do that? Besides, look at their fancy clothing, it's not every day you meet such people with great undercover uniforms."

"True. But—"

"Well, let's keep that little secret between us."

Klink smiled. "Hogan your excused."

Colonel Hogan gave a salute, before walking out.

Hogan went back to the barracks and Sam immediately asked, "Well, Colonel, how did it go?"

He smiled. "You're in."

Sam and Dean sighed, thanking whatever higher power was keeping good luck on their side for the time being.

"Now, for the big plan, LeBeau did you and Newkirk find those two missing sergeants?"

"Yes, sir, they are waiting down in tunnel 5," LeBeau said.

"Good, listen, we'll have to move fast—" Hogan never finished his sentence as it was cut off by a gasp of pain.

Dean turned to his brother knowing that it was him that had let out the gasp, and was horrified when Sam put a hand to his forehead. His knees buckled and if Dean hadn't caught him, he would have collapsed in a heap to the floor.

Once they were safe on the ground, he asked, "Sam? Sammy? What is it? What's wrong?"

"Dean… head hurts," Sam said, clutching his head as the pain continued to bombard his brain.

Dean rubbed comforting circles on Sam's back, knowing there was nothing else he could do but wait for the vision to end, and judging by the looks of it, it was a doozy.

"Dean? What's wrong? Is he okay?" Hogan asked, suddenly very concerned at why the younger brother was hurt. He didn't like to see any of his men hurt.

Dean looked up at him with anger in his eyes. "Not. Now." He knew that the colonel was concerned, but he didn't have time to worry about that, knowing that the constant chattering wasn't helping Sam.

He looked back to Sam, whose glazed eyes were slowly returning to normal and he began to stir, but coming out the vision was always worse than when the vision hit.

He turned back to the colonel and asked, "Hogan, do you have a private room where I can take Sam?"

"Yeah, my office. But Dean, I need to know what's wrong?"

Dean looked at him with anger in his eyes. "Colonel, my top priority is Sam, and right now, I can't answer your question unless Sam here lets me, it's his problem."

Hogan really wanted to demand—no… order the older Winchester but something told him that Dean wouldn't listen, especially when it came to his brother. He just watches with confused eyes as Dean helped Sam up, and led him to his quarters. Everyone in the room was quiet, all wondering what was going on but all too afraid to ask, and so they went back to discussing the mission, leaving the brothers to themselves.

Dean helped lower Sam down on the bed, and Sam put up an arm, shielding the blinding light from his eyes. It only made the pain in his head worse. Dean was by his brother's side, waiting patiently for his brother to explain the vision.

"Dean, there's trouble. A ghost—or spirit is going to attack Klink," Sam said through gritted teeth. Dean really wished they had brought the aspirin, Tylenol, or better yet, Ibuprofen.

He rubbed his brother's arm. "Shh… we'll figure it out, Sammy. But, before you sleep, Hogan and his men are wondering what happened."

Sam looked up at Dean horrified and grabbed his arm. "They don't… I mean… you didn't…"

Dean shook his head, and put a comforting hand over his brother's. "No way, dude, I told Hogan that it was up to you if you want me to tell them." Dean could see the fear and uneasiness in his brother's eyes and quickly jumped the gun. "We don't have to tell them, Sam."

Sam shook his head, slightly, not too much to cause more pain. " No, you can tell them." Sam felt the luring of sleep pull him under, but he tried to fight against it.

"Okay, Sammy, you just sleep."

Once he made sure Sam was comfortable and asleep, he walked out and everyone immediately crowded around, asking the big brother if Sam was okay.

"Everyone Sam's fine," Dean said, walking through the crowd over towards the table, plopping down, staring at everyone. "Now, you have to understand that what is happening to my brother isn't anything we can do."

"But Dean, he…" Newkirk tried to say, but was quickly cut off by Dean.

"Sam's psychic, he gets premonitions, usually, we get a heads up before one hits."

"The headaches?" Hogan asked, immediately realizing the answer.

Dean nodded. "Yeah."

"How long has this been happening?" LeBeau asked.

"About six months, first they started in his sleep now they happen while he's awake or asleep."

"My word," Newkirk said.

"Listen, Hogan, do you have any pain medication? After an intense episode, Sam will usually have a headache for a few hours, so he'll have to be somewhere quiet, but I need to be with him."

"Of course, Dean, use my room for as long as you need, the men and I will plan the rest of the mission in the underground. But is it okay if LeBeau and Kinch stay up here?" Dean nodded, and watched as he turned to the two men. "If, Schultz or any other guards come quickly tell me, and LeBeau, go get the pain medication."

"Yes, sir," they said together, and LeBeau scurried off while the rest of the men went down into the underground and Dean went to his brother with Kinch behind him.

"Will he be alright?"

Dean sighed. "Should be after some sleep."

"What does he usually see in these… visions?"

"Death mostly."

Kinch's eyes widen. "I'm sorry, I didn't mean to pry."

"No worries," Dean said, walking into the room where his brother still laid flat out sleeping. He was twitching ever so lightly, and an occasional low moan would escape his parted lips.

Dean sat down beside him, rubbing his sweaty hair out of his eyes, still seeing the pain lines fixed on his brother's face, and tightness gathered around his heart along with a sense of helplessness. He knew there was nothing he could do to take away the pain Sam was feeling. All he could do was sit by and whisper comforting words in his ears.

A soft knock on the door, had Dean up and over there in less than a second, and when he opened it, LeBeau stood holding out two white pills and a cup of water.

"They aren't real strong, but they'll help… hopefully."

Dean took the pills and water, and laid them on Hogan's table, before returning to his brother's side. Sam, I need you to wake up, and take these pills it'll help with the pain."

Dark eyelashes fluttered, revealing dull pain hazel eyes. "De…"

"Yeah, it's me, Sammy." Dean said, as he helped Sam sit up, and once Sam was awake enough to swallow the two small pills, Dean helped him back down. Man, this day just gets better and better… he thought.
