-----------------------------------------------------------------------------------------------------------------------

Adam walked into the bedroom area, looking for you and finding you in bed, wondering why you were there. "Y/N! It's time to get up, let's go. Dean's got us a hunt." he yelled, causing you to cringe and cover your head. In truth it wasn't that loud, but you knew that if you didn't act this out right no one would believe you.

"Shh...." You begged softly, sitting up slowly, putting your hand on your forehead. "My head is killing me." you mumble.

Adam looked at you in surprise, before sitting down on the bed beside you, and studied you for a moment. "I'll go tell Dean that you're sick, don't move." he said, getting up and dashing out of the room and slamming the front door.

You waited two minutes, then got up and ran for the bathroom, as the front opened. You slammed the bathroom door shut and locked it, turning on the water, low so it could barely be heard, and dropped your pants, and sat on the toilet, just in case they opened the door. You kept the water hot until it was boiling, then splashed it on your skin, and put it on the thermometer, until it beeped, saying 102.3.

"Great, now I will be watched for vomiting." you whisper to yourself, not so sure that you love this plan, as you walk out of the bathroom slowly, handing the thermometer to Dean who was waiting anxiously for you, and go back to lay down.

"Y/N, what are your symptoms?" Dean asked, looking at the thermometer in concern, not liking how high that fever was.

You mumble an answer, still cradling your head, and curled into a ball, making it appear that you were cradling your stomach too. You were purposely making it hard on Dean to understand you, so that he couldn't give you any meds.

Adam walked up to you, got down by your head and whispered softly. "What's going on with you, Y/N?" he asked.

You groan softly, turning your face into the pillow, as if even the whisper hurt your head.

Adam walked back over to Dean, and talked to him in hushed tones. "Fever, migraine, nausea... its a good start." he said simply.

Dean nodded, grabbing tylenol and pepto, which always made you puke if you took it and you weren't sick.

This wasn't your first time faking sick, you'd accidentally taken pepto for appearances, and within ten minutes, were vomiting everywhere. You had a feeling this time would be no different.

Dean brought over the meds with some water, which you slowly sat up and dutifully swallowed, then lay back down.

Adam brought over a bucket in case those meds didn't stay down, which you positioned your head perfectly over as the hiccups set in, from the darn pepto.

He sighed softly, shaking his head. "Its that pepto. Y/N's stomach can never handle pink crap." he said defeated, as you urped up the pepto and tylenol. He climbed onto the bed and got behind you, rubbing your back gently as the urping turned to full on vomiting.

Dean sighed softly in frustration, looking at Sam, who looked suspicious. He sighed to Sam, asking him questions, but Sam ignored him, he was more interested in you and your show of no longer vomiting as you curled in on yourself and cradled your head again.

As the evening wore on, Adam stayed by your side, but Sam and Dean left you alone.

Eventually everyone went to bed, and so did you, falling asleep quickly, only to wake up around 4 am, feeling like you were going to throw up again. You barely got your head off the bed and over the bucket on the floor, before the gagging set in.

Adam shot upright on the couch and rushed to your side, feeling your forehead and pulled back in surprise. "Dean! Y/N is actually sick now!" he yelled, and you knew the jig was up. They had spent yesterday taking care of you, even though they knew you weren't sick. That made you feel beyond guilty, which set your stomach rolling, and you officially started vomiting... again, only this time it was without help of any kind.

He pulled your hair back from your face, not wanting it to fall into the vomit's path. "You're okay, just breathe between heaves." he instructed, feeling you gasp softly, between aggressive heaves.

Dean got out of bed, grabbed the thermometer and some Tylenol for you. Once the vomiting stopped, and you could breathe, he put the thermometer in your mouth without a word, waited for it to beep, and pulled it out and frowned. "103.2. How do you feel?" he asked.

You heard the temperature, which explained a lot, of why you were freezing one second and burning up the next second. "I can't regulate my temperature." you said, as your teeth started to chatter.

"Take the blankets off, only the sheets." Dean instructed, watching as Adam did as he was told.

"What if Y/N gets too cold?" Adam asked in concern, watching you closing as you curled into a tight shivering ball under the sheet.

Dean sighed softly, shaking his head. "The fever is too high, we need to wait it out. No more blankets." he said heavily, as he walked over and got a glass of water and returned with it, offering it to you.

You sit up slowly, to not provoke the dizziness that set in after you started vomiting. You take the cup, swallowed only enough to swallow the Tylenol he handed you, and clutched your head as the dizziness returned full force, making you groan in discomfort.

"What's wrong, Y/N?" Sam asked from his bed, as he got up and headed to draw a cooler bath in the hopes of lessening your fever.

"M dizzy." You say weakly, sinking down under the sheet, squeezing your eyes shut, in the hopes the dizziness stops and you don't end up sick again.

Sam walked back into the room. "There is a bath to cool Y/N's temperature ready." he said, as Adam and Dean moved to help you up. Once you were upright, you whimpered, your legs shaking and barely able to move thanks to the fever.

"I think Y/N's fever is higher." Adam said, as he could feel the heat radiating off of you, and it felt too high for comfort.

Dean nodded his agreement, as they helped you into the tub, fully clothed for privacy purposes. He grabbed the thermometer, and checked your temperature again, only to find it had risen.

"103.9, alright, any higher and Y/N will boil their brain. Slowly scoop water over their head, its time to cool down." Dean instructed firmly, as he climbed into the bath behind you, to keep you upright.

He facilitated the water pouring for what felt like hours, until he was satisfied. He used the thermometer and checked your temp again, to find it had dropped, much to his relief.

"What's it at?" Adam asked in concern, as he stopped dumping water on your head.

"101.5," Dean said in relief, as you lurched forward with a harsh gag. "Drain the water," he instructed, as he rubbed your back gently. "You're okay, let it out." he added.

You urped up the Tylenol and water a bit aggressively, and dry-heaved for ages, until only bile and stomach acid colored the water.

"I'm so sorry." you whispered, feeling embarrassed that you had basically thrown up in the tub and it was going to get on Dean.

"Not the first time, won't be the last. Take a rinse off, and we'll get you into bed and resting again." Dean said, looking at the clock, which read 7 am. It had been three hours since all this started.

Sam and Adam helped you up, then helped Dean up, so that you could rinse off, so Dean stepped out, as you rinsed off. The water felt amazing on your bare skin, as you stripped your clothes off, and rinsed off, but the water also set your stomach off. And you doubled over, dry-heaving in the shower, until only bile came up again.

"You good?" Dean asked awkwardly, as he knew not to open the curtain as you were naked.

"Yeah, I am fine." You said breathlessly. You finished rinsing off and wrapped a towel around yourself, before stepping out of the shower woozily.

"Easy, easy. You're woozy?" Dean asked in concern, watching you closely.

You give a barely perceptible nod, as you are afraid that if you open your mouth, bile will come out again.

Adam walked in with clean clothes for you and Dean. "Clean clothes for you both." he said with a smile.

Dean slipped in the shower, as you sat on the toilet and started to get dressed after Adam left. "You decent?" he asked when he was done showering.

"Yeah, give me a sec to leave." you say tiredly, as you get up and leave the bathroom, only to b greeted by Adam at the door.

"I got Y/N," Adam told Dean and shut the bathroom door, as he led you to bed, which he had made all nice and cleaned out the bucket for you. "Get some rest." he said, as he curled up on the bed beside you to keep watch over you.

Adam watched over you, helped you when you got sick, which was every time you put something in your mouth, and he didn't complain at all.
