This is something that has been sitting in my stories-folder for almost a year now and I recently rediscovered it and saw that quite a lot of it was already written and I still liked it. It probably won't be very long just two or three chapters total. I hope you'll enjoy.
"That was Bobby. He wants us to check out a possible case in Golden, Colorado. Several young women have been sexually assaulted and they describe their attacker as distinctly non-human. Local police blame it on alcohol and possibly other drugs, but Bobby isn't so sure. And we're only a few hours away," Sam told his brother after hanging up the phone.
They had just finished another job, a regular haunting, and hadn't made any new plans. At the moment they were sitting in a small roadside diner, having lunch.
"Does it have anything to do with the apocalypse?" Dean asked.
"He didn't say," Sam answered and, sensing his brother's reluctance to take the case, started to say, "But I think…"
"Wait, did you say Golden, Colorado?" Dean suddenly asked between two bites of his bacon-cheeseburger when he'd processed all the information, interrupting Sam. "Isn't that where the Coors Brewery is located?" Sam simply nodded and picked at his salad. "Awesome. I say we check this thing out." Dean was so excited that he almost forgot about his burger.
The next day the brothers arrived in Golden. Sam had used the drive to read the police reports for all the assaults, but it hadn't helped him to figure out what they were dealing with. It seemed to confirm Bobby's suspicion that something supernatural was going on though.
As soon as they had found a motel room Sam got out his laptop to do more research and Dean felt restless, so cleaned his gun until his stomach gave an audible rumble. This made Sam look up for the first time in hours. Dean pretended not to notice and kept polishing his already spotless gun. Sam glared at him for a moment but when Dean didn't react he finally said something.
"Are you gonna get some food or what?"
"Food?" Dean asked innocently and suddenly found himself on the receiving end of Sammy's favorite bitchface.
"Your stomach is making it hard for me to concentrate," Sam said slowly.
"Buy some earplugs," Dean suggested but pressed his hand against his stomach when it gave an extra loud growl.
"Jerk."
"Bitch."
Dean would have loved to stay and mess with his brother some more but he really was hungry so he got up, grabbed his leather jacket and his car keys and left the motel room. Sam hadn't said anything about wanting food, too, so Dean didn't bother to look for a place where he could find something green and leafy for Sam. He just drove through town and found a place that sold hot dogs by a small park. He bought one and sat down on one of the benches to eat.
Before he could take the first bite, he heard a soft fluttering behind him. He didn't need to turn his head to know who it was.
"Hello, Dean," the gravelly voice greeted him.
"Hey, Cas," he said and then finally took a bite from his hotdog as Cas sat down next to him.
"Dude, could you stop staring? It's fucking weird," he said a minute later when he could feel Cas' eyes on him, watching him eat. It was unnerving and made him feel strangely self-conscious.
"My apologies, Dean," Cas said and looked at the children playing in the park instead.
"Get your own hotdog, if you want one so badly."
"I do not wish to eat," Castiel replied evenly.
"Okay. What are you doing here then? And how did you find us?"
"Bobby told me where you would be," Castiel explained.
"Okay, and what are you doing here?"
"Nothing in particular. Just….taking some time off."
"Taking some time off?" Dean asked in disbelief. He couldn't see Castiel just 'taking some time off'. But Castiel didn't elaborate on it and when Dean prepared to ask more questions he simply vanished, leaving Dean confused and a little disappointed at being on his own again.
He quickly finished his food and then got back in his car, driving aimlessly through town until he suddenly found himself in front of the Coors Brewery. Since he didn't really feel like returning to the motel yet he decided to check it out and was delighted to see that they offered free tours of the brewery.
It really was no question for him whether to go inside or not. It was not like he could do much back at the motel anyway, with Sam using the laptop to do research and no other new leads for them to pursue.
The tour was nice, interesting even. The best part though was the end, where he was allowed to sample some of the beer. Yeah, it had definitely been a good decision to take this case, even though they didn't yet know what they were dealing with.
After the tour Dean was hungry again. That hotdog from earlier had hardly been more than a snack. He tried calling Sam to see how he was doing but the line was busy. Probably Sam was talking with Bobby. Well, the two of them were expert researchers and they didn't necessarily need his help.
He found a diner and ordered a burger and fries and started eating. After a few bites he suddenly caught himself wishing Cas was there, staring at him. He didn't dwell on those thoughts though and finished his dinner, getting some pie for dessert. When he left the diner it was dark and he felt a little guilty for leaving Sam alone for so long. But he figured that Sam would have called if he'd found something or had needed Dean's help, so probably it had been a very uneventful afternoon for his brother.
He returned to the motel and found Sam asleep, with his head on the table next to his laptop and a stack of police reports. There were some containers with leftover Chinese take-out on the table. At least Sammy had remembered to eat something. Dean gently touched his shoulder and shook him awake.
"A bed would be more comfortable," he teased and Sam glared but really he was thankful that Dean had woken him or his neck would hurt like hell the next day.
"Did you find anything?" Dean asked when Sam came back from the bathroom.
"Nothing. There's nothing to go on other than the eye-witness reports and you know how unreliable they can be. And the girls couldn't really describe their attacker. Maybe they were too drunk or too scared, I don't know. It's all vague and contradictory and I have no idea what attacked them," Sam answered, sounding tired and frustrated.
"So what are we supposed to do?"
"Talk to them again? Wait for another attack? I don't know Dean. Maybe someone date-raped them and whatever they saw were hallucinations. Anything is possible at this point," Sam answered and stifled a yawn.
"Okay, let's think about this some more tomorrow. You obviously need your beauty sleep."
Dean only barely dodged the pillow Sam threw at him. He didn't bother to pick it up, annoying Sam some more who had to get out of bed again to retrieve his pillow. But by the time Dean was ready for bed Sam already fast asleep again.
A few hours later his phone rang and within seconds both brothers were awake and alert.
"Are you two idjits still sleeping?" Bobby's voice asked when Dean picked up his phone.
"Bobby. It's only six in the morning and we haven't got any leads to follow," Dean defended himself and Sam.
"Well, boohoo. I haven't even been to bed yet. And if you hadn't either you'd have a lead now. Police found a body. The girlfriend reported it in the night but it took a while until they got her to make some sense. She was talking about a monster that killed her boyfriend."
"Any details about the monster?" Dean wanted to know.
"No. But she was right about the killing and it definitely wasn't her. Maybe she's right about the monster, too. Worth checking out, I'd say, so get your lazy asses to the crime scene," Bobby said and then gave Dean the details he needed. The crime scene was behind a bar just outside of town, where the woods began.
"Okay, Bobby, well have a look. And you should get some sleep. You're cranky," Dean told him when he had all the information and then hung up immediately to avoid Bobby's response to his last remark. He quickly told Sam everything and the two of them changed into their suits and were on their way within fifteen minutes.
