"What the hell, Sam?" Dean walked into their hotel room in Kearney, NE and slammed the door behind him. Sam flopped down face first on the right bed and sighed.
"It wasn't my fault, Dean! How the hell was I supposed to know silver was that thing's weakness. It wasn't in dad's journal."
Dean sat down on the corner of the bed and toed his muddy boots off. Without thinking, he took off his clothes down to his boxers and watched as his brother's jaw drop and fake a yawn. Dean noticed, but he failed to make any kind of connection. He turned his back on Sam and headed for the shower.
Sam had been awake for hours. Dean had gotten out of his shower and went to bed at 8 pm and it was now 5 am. Sam couldn't sleep a wink. At 8:30 pm, Sam gave up trying to sleep at all. He went to his laptop, doing research on the monster they failed miserably at trying to kill. It wasn't like they needed the research. They now knew that silver was it's weakness. But every time Sam thought about laying his head down on that scruffy pillow he couldn't help but cringe.
Dean finally woke up around 10. He rose, ran his hands down his face and sighed.
"Another day in paradise." He whispered his silent mantra to himself. He finally looked up and saw Sam sitting at the table, engrossed in an article about weird things in Kearney.
"J'ew sleep?"
Sam finally looked up, saw Dean's disheveled messy hair, he chuckled lightly, and shook his head 'yeah.'
"A little."
"Wanna talk about it?"
Dean shuffled to the kitchen and pulled the coffee carafe out of it's cradle and started the tap water.
"Nah," Sam rubbed his eye with his balled up fist and yawned. "But I'm telling you, a twister would do this town a favor."
Dean let out a big yawn as he shoved the coffee carafe under the water, letting it fill to a full 12 cups.

Dean got dressed and he wanted to find breakfast. Hell, a hunter runs on his stomach. They'd been having too much fast food. Sam was starting to grumble about it so Dean swiped some poor guys card and off they went. They found Peggy's diner at the edge of town and they were seated.

"What are you havin', doll?" The plump red headed waitress asked impatiently as she popped her chewing gum.
"I'll have the cheeseburger and fries. And Sam?"
Dean looked at Sam and he was extremely focused on the kitchen at the edge of the counter. The large cook flipped sautéed onion and peppers and every once and awhile you would see flames licking the side of the frying pan.
Every time the cook flipped the pan, Sam would flinch. His tired eyes squinted, hardly keeping them open long enough to cringe.
Dean snapped his fingers in front of Sam's face, trying to refocus him.
"Whaddya want, Sam?"
"Uhh." Sam blinked, closing his eyes shut tight for a second, trying to remember where he was. He shut his menu closed with a heavy thud. "Not hungry."
Dean's eyes flew open. He scoffed and put his hands down flat on the table and turned to "Marge".
"He'll have a chicken salad."
When Dean turned back, Sam was refocused on the fry cook.
"Dude, what's your trauma?"
Sam licked his lips and turned to Dean, slinking down into his seat.
"I just didn't sleep... I mean, I just-" Sam cut himself short. No chick flick moments. Right. He'd been on the road with Dean for what, 6 months? He still had to repeat that to himself.
"What, Sammy?" Dean looked both confused and compassionate for once. He could plainly see he was worried for Sam. He hadn't had a sleeping issue since he was a kid. Dean thought for a second.
No. Sammy's always had nightmares.
when Sam would get scared when he was a kid, he would try to crawl into their dad's bed. John would roll over in his drunken stupor, and kick Sam out. So Sam would get so scared he would start crying and go back to bed. He would cry silently, for hours. So Dean, being the amazing brother he is, would crawl into Sam's bed and hold him while Sam sobbed; and then eventually fell asleep.
Was that it? Was he having nightmares again?
"Look, Dean, don't worry about me." Sam shut his eyes tight and seemed to have a hard time opening them again. "I'm fine."
"No, Sam, obviously you aren't. You can't even keep your eyes open. And I hate to break it to you, but I think that fry cook's married."
"Wha- no! That's not...-" Sam pinched the bridge of his nose in frustration and felt a bit of relief when he closed his eyes. "It's the fire, Dean ." He flailed his hand out in front of him.
"What's the fire?" Dean leaned forward.
"That's what I'm looking at. I keep having these...Nightmares."
"Nightmares?" Dean barely got the word out before Sam started muttering.
"They're not even nightmares, they're worse than that. They're these night terrors. Every time I close my eyes.. I mean, it starts out like a good dream.. Um.. Then it just gets.. Bad. Fast. And-"
"I get it."
"No, I don't think you do, Dean ."
"Nahhh, I get it. You just lost Jess, you're out on the road with me, blah blah blah. Listen, I get it. But whatever it is, you better buck up for this hunt 'cause this next one's gonna be tough with you at half speed."
"I know." Sam scoffed and played with the edge of the upside down coffee cup the sat at the edge of his plate.
They ate their food silently, Sam ate very little. But periodically, he would look up and watch the fire for a little. Flinching in fear every time one flame got out of hand.
Dean gave Marge a decent tip for dealing with Mr. Coo Coo nest and waved a gentle goodbye when her eyes lit up. Sam darted for the car and Dean followed after him. 'Thank you for giving her a decent tip, Mr. Tomakato.' Dean said sarcastically to himself as he slipped the visa back into his wallet. Sam glared at Dean and scoffed.
"Sam!"
Sam kept walking.
"Sam, stop!"
Sam stopped in his tracks and refused to turn and face Dean. Dean went around him and put his arms out. Dean pushed a hand into Sam's chest and pushed him into the impala. Dean got in his face.
"Sammy, seriously, what's going on?"
"What, Dean you want me to stand here and tell you how scared I am? How I haven't slept for a week? I already told you. I'm fine."
There noses almost touched as Sam leaned forward, feeling Dean's warm breath on his neck and the friction of his jeans rubbing against his own.
"No, asshat. You aren't." Dean poked a finger into Sam's chest. "Tell me before I beat it out of you."
Sam sighed and walked away from Dean and to the car, the heat too much to bare, opening the passenger door and looked desperately at Dean.
"Consider yourself warned. I'll tell you. Just..." Sam laid his palms flat on the impala roof. "Not here." He got into the car without another word.
They drove back to the hotel while Dean jammed to AC/DC's shoot to thrill.
They arrived, and Dean sat in idle for a minute just to hear his baby purr. Sam got out and Dean followed, Sam unlocking the door. The boys sat in the adjacent bed and just stared at one another. Waiting for the other to talk first.
