There was no telling what was to come with all of the simultaneous conflicts floating around in Dean's life. Though he had seen hard days in the past, he couldn't help but have what he would describe as a ball of stress in his stomach. Being the epitome of stoicism he was, he kept his distress to himself, and trudged through the unpleasantness.

All he could do for the moment was wait for what was to come next. It was irritating, feeling so passive. Waiting to see what Crowley would do next. Waiting to see if Sam would forgive him. Waiting to see how the mark of Cain would affect him. Waiting for his guilt to subside. Waiting for death to have him, once and for all, sooner or later.

He tried to fill his restlessness with mundane everyday activities around the Men of Letters' headquarters, giving himself small doses of apple-pie-life. He cleaned his room, the bathroom and the kitchen. He polished some guns and knives, and prepared some salt and silver bullets. He decided to take a break and watch a movie on his laptop, and have some left-over Cantonese-Szechwan when he felt a mild head ache coming on - he attributed it to it being time for his post-lunch, pre-supper snack time.

Dean felt a little funny afterwards, and decided to take a nap in his room. He woke up almost an hour later. He'd been sweating a little and his stomach was beginning to cramp. "Take-out must've gone bad," he thought. He sat up, rubbing his abdomen in circles to soothe the pain.

Sam knocked on his door, Dean inviting him in with a "yeah". He quickly changed his demeanor, what with their new strictly business thing that had going on. More than his stomach could ever pain him, were the lengths Dean had gone to protect and keep his brother near and dear, only to have him push him away, and further the desolation in his heart, that the brotherly love they once shared quelled. So Dean didn't want Sam to mind him, or the havoc that leftovers and the ball of stress wreaked on him.

"Dean," Sam, began - though the elder sibling was trying to appear as though he was okay, Sam could see through him and read him like a book. He interrupted his thought "- are you feelin' okay?" he asked casually.

"Uh... Yeah. Just tired," he lied.

"Are you sure? You look a little green..."

"I had the leftover take-out, it's just not sitting well," he admitted. At least, Dean hoped that it was a simply a stomach ache, and nothing... biblical.

"I was gonna head to the store, get a few things. You need anything?"

"No. I'm good. Just the usual…"

"Beer and Pie"

Sam did a little better than the usual. He got Tylenol incase Dean got feverish, Gravol incase he threw up, Imodium incase it would come out the other end... Chicken soup and soda crackers and ginger ale, and a hot water bottle because Dean had a tendency of getting bad cramping.

Sam felt conflicted in his caring for and helping Dean. Like his anger and frustration wavered temporarily in his time of need. In the grand scheme of things, he needed him to be well to complete to defeat Abadon.

When Sam returned to the headquarters, he's found Dean at the conference table of the main room, doing research. A fellow hunter had called asking for an incantation to get rid of the spirit of a wicken.

Sam looked at Dean, as to say "what's going on?"

"That was Davidson; he's working a witch hunt."

"Huh," Sam answered, noticing Dean's improved appearance. "You're looking better..."

"I told you I was alright," Dean, insisted. He turned his attention to some files he was reading through, but couldn't help but be distracted by Sam staring at him with concern. In return, Dean glared back at him, as to say stop staring at me. Sam took his provisions to the kitchen to put them away.

The elder of the two felt himself relax as Sam left the room, and gave way to his abdominal discomfort, slouching in his seat a little. He then felt a twinge behind his eyes as he thought of the incredible pleasure and pain that came with Cain's mark and infamous sabre. He blinked to try to clear the image from his head. Before he knew it, he was overcome with stomach cramps and nausea and was bolting to the bathroom.

Sam hadn't spent a long time in the kitchen, and when he came back to the main room, he was a little surprised to see that Dean wasn't there. In the quiet of the room, he took a moment to appreciate that in the midst of this whole demon ordeal, he could find time to take care of personal things, like catching up on laundry, or having a little calm and doing some research…

For a time, he'd been studying the Hebraic version of the Cain and Able passage, searching for something that may help Dean. He came across a compelling verse and wanted to see if Dean would it might reveal something… He didn't know…

He headed to the computer room, and then the garage, and began getting impatient. Where was Dean? The way things were with Dean, otherwise, this would have reminded him of his childhood and he would affectionately think of games of hide and seek in Bobby's junk yard when he was 5 and Dean was 9. Rather, it fed into this gnawing irritation that he'd been robbed of his freedom, and betrayed by Dean.

"Dean, where the fuck are you?"

Dean was getting his bearings after throwing up a little. He rinsed his mouth, deciding against a full brush job after it sent him gagging again. He looked at his reflection in the bathroom mirror and wondered how he would keep up appearances when he looked so sickly, nauseated and lethargic. He kept a bottle of bismuth tablets in his hunting duffle bag for those motel nights when he'd had a few too many burgers, beers and pie. He thought that he was usually pretty discreet about his bouts of digestive distress if they weren't too bad. Truthfully, Sam couldn't ignore the tell-tale stomach gurgles and belches on their long stretches across state lines, but he knew that Dean preferred to keep to himself on these things, so he chose not to intervene unless it was grave.

Why couldn't Dean choose not to intervene?

Dean made haste, as fast as he could go without his head spinning and his stomach heaving. His trek to his bedroom was soon interrupted when he ran into Sam in the hallway, as he was coming out of the bathroom.

"Dean – there you are," finally, Sam had found Dean.

Dean tried to steady himself, straighten his back and not alarm his younger brother. This mound of tension that was building between them created this emotional wall that rivals the wall of Berlin. They were like strangers. Dean didn't want Sam to know, but was betrayed by his body when he fainted.
