It hadn't been long, since breakfast, for America to fall asleep because of his sickness and exhaustion. Russia wanted to give him some cold medicine, once he was finished eating his own breakfast (he would've done it sooner, but his stomach was growing more and more impatient for food as time passed on, and the hunger caused him to forget), but he was delighted to find the young nation was sleeping. Since he would need a lot of rest, in order to recover from his sickness at a faster pace, his caretaker chose not to disturb him, and figured he could give him medicine later.
Russia never even considered checking on the young nation more often than every half hour. Other than the fever and lack of appetite, he didn't detect any symptoms he deemed too concerning. He hadn't even been aware of the fact that America was nauseous. This, he came to regret, as when he walked by the other's bedroom, he couldn't help but grow anxious at the sound of gagging. He peaked into the room to determine whether or not America was okay, but grew even more worried at the sight of him. The one he was caring for appeared to be struggling to turn over from laying on his back. His face was strained; as if he was trying to keep the contents of his stomach from entering his throat. It wasn't long before there was some gurgling.
In a bout of panic, Russia dashed over towards America, and grabbed the other, so he would be able put him in a sitting position. He didn't care if he was being too rough. He'd rather have his comrade be bruised than drown in his own vomit. Fortunately, he'd managed to save the other from this fate in decent time, as right when he was placed in a sitting position, the contents of his stomach poured from his mouth. Russia didn't do anything to try and avoid the incoming vomit, as for one, he didn't believe his fellow nation was strong enough to remain sitting, and for another, he didn't have any time to react when the vile substance splattered onto his arm. Now wasn't the time for him to be grossed out anyway. He needed to focus on allowing his ally's body to reject whatever substance was bugging his stomach in a way that wouldn't cause him too much harm.
By the time America was finished vomiting, the vile substance was all over his blanket, shirt, and his caretaker's sleeve. He showed no signs of guilt for having made a mess, though. Despite the fact that he was groaning, due to stomach cramps, there was also relief apparent on his face. He was happy his caretaker was willing to put him in a sitting position while he puked. There'd been times while he was under the scientist's 'care' where he grew nauseous, and was unable to turn over from laying on his back. No one would bother to try and flip him over, so he would end up with vomit in his lungs. Which would always lead to agony. This was how he found out it was important he didn't lay on his back if he needed to let the contents of his stomach out, and he was appreciative towards Russia's willingness to save him from such pain.
Russia scooped America into his arms, once the other was finished regurgitating his breakfast, so he could carry him into the bathroom to clean him up and change him. He didn't care if this caused their clothing to become more messy, as their garments were already filthy.
Upon arriving to the bathroom, Russia searched for the best place to set the young nation down, so his arms could be free while he cleaned himself and America up. One glance at the toilet made him figure it would be the best thing to let the one he was caring for sit on; while the lid was down, of course. After, having the other sit on the toilet, he removed his jacket, in order to prevent himself from being burdened by the warm, clunky liquid on it. Since he didn't want to waste time going all the way to the laundry room, as he figured it would be best not to leave America shivering on cold porcelain for too long, he placed it in the tub. He was aware of how disgusting this may appear to be, but he promised himself he would clean the tub, as soon as he was finished taking care of his sick comrade. He wasn't worried about anyone choosing to shower in that particular bathroom, though, as it was the ill nation's personal bathroom, and it was attached to his bedroom.
Russia was quick to gather some new clothes for America. He didn't waste a single second while changing him and ridding his face of vomit. The caretaker was sure the other was relieved when he pulled him towards his body, after having to sit on the cold porcelain for a short while. America's shivering was violent. The room must have been frigid to him. Though Russia was sure his body was providing him with lots of warmth. He could tell by how the other was snuggling against him the moment any conduction developed between the two.
America was aware of the fact that horrible, unfamiliar memories attacked his mind when he first observed the human in front of him with his glasses on. These memories always gave him a sense of emptiness within his chest in the other's company. Though before the doctor's appointment, it became more bearable to deal with as time passed on. He was also aware of how his caretaker forced him to go through some uncomfortable procedures, which he believed would only do him more harm than good. However, he couldn't help but become more forgiving towards those unfortunate experience. Russia had done him a huge favor not too long ago, and he was grateful for the agony he saved him from. He was also grateful for the gentle behavior his caretaker was expressing towards him.
Russia lifted America into a carrying position once more, and headed out into the living room to make the other comfortable on the couch. The blankets and sheets on his bed would have to be changed now, so the young nation wouldn't be able to sleep in his bed at the moment. Besides, on the couch, it would be easier for him to keep America in a decent laying position than it would on the bed. In case he happened to throw up again, Russia was sure he would remain on his side, and so he wouldn't risk causing himself any harm.
As soon as America was placed on the couch, Russia was quick to retrieve a blanket and thermometer. He made sure to wrap the blanket around the other's form tightly, before placing the thermometer in his mouth to check his temperature; only to frown when he found it was now at thirty-nine degrees Celsius. Sure, this wasn't the worst his temperature could be at, but he still didn't enjoy the fact that it was rising. There were still some things Russia could do for his ally to make him more comfortable and improve his condition though. He still hadn't given America his medicine yet, and the other also appeared to be in need of some water.
Russia set off to gather these needed items, and elevated America's head, so it would be easier for him to have him consume the medicine and water. He was happy to find the ill nation not rebelling against having the bitter flavor of medicine in his mouth, as he would've expected him to. Though, he figured this could be due to his exhaustion and stomach cramps. He must not have had enough energy to resist.
By the time America was finished consuming these much need fluids, Russia made sure to place a bucket next to the uncivil nation's couch, before he happened to forget. The caretaker allowed himself to relax, though, when he figured he wouldn't need to do anything else for his comrade at the moment. He settled for stroking America's hair, in an attempt to comfort him as he slowly drifted off to sleep. It was refreshing to see the young nation enjoy his affection, instead of resenting it.
While Russia watched America fall asleep, he spoke to him in a quiet voice, though he was aware of the fact that the other wouldn't understand him, "I hope you feel better soon. It's too bad that you have to deal with this sickness. Especially after your horrible experience at the doctor's. I guess none of this should surprise me, though. You're immune system is a lot weaker than it used to be, so it's really a wonder that it took you this long to get sick."
The soft words were helping America drift off to sleep, and he was curious towards what his caretaker was saying. Though, it wasn't too important for him to know at the moment. Instead, it was the tone that mattered more to him, anyways, and so he continued to listen as the other spoke, "You're very strong, though. So I'm sure that you're immune system will improve in a short amount of time."
With that said, Russia gave America's head a few light pats, before leaving the young nation alone to rest.
