Part 2! :)

Louis was in bed with an awfully hot Harry, alternating between belly rubs and head massages and doing his best to keep the younger boy's spirits up. Harry was in a lot of pain and Louis knew that, though the boy was all but silent. Harry was so tired. Sleep wasn't coming easy at all, at he was in desperate need. His stomach was just such a sick mess, he constantly felt on the verge of throwing up. His belly was full of air and burps kept escaping him, much to Harry's dismay. His cheeks would burn a bright pink every time it happened and he'd dip his head away, murmuring shaky apologies. "It's okay, don't apologize anymore," Louis said softly.
Harry hid his face against Louis's chest and whimpered.
"It's embarrassing, Lou."
Louis sighed and scratched Harry's back lightly.
"There's no reason to be embarrassed, okay love? No reason. You're so ill," Louis soothed.
Harry didn't answer. Louis knew that the silence didn't mean much like it usually would though, Harry just wasn't talkative when he felt so bad.
"I think you need another dose of medicine, H. It doesn't look like the last one helped any," Louis said, tired of watching Harry's face twist painfully. Harry didn't answer again and Louis sighed. Harry's fever had only been getting higher since yesterday, the boy at least needed to take something to keep that in check.
"I'll be right back, okay? I'm going to grab something for that fever," Louis said, beginning to shift under Harry's weight.
Harry weakly gripped at Louis's t-shirt but it wasn't doing much of anything to stop Louis's movement.
"Stay."
Louis paused, heart hammering at the desperate word. Harry didn't want Louis to go anywhere.
"You need the medicine, Harry. I'm worried about you," Louis explained. He had to do what was best for Harry. 
"M'fine like this," Harry mumbled out.
"No, you're not. I'll be so quick, you won't even realize I've left," Louis said. He was going to get Harry medicine no matter what, but he really wanted Harry to be okay with it.
"Mmmmmh," Harry moaned before muffling another burp.
"Please? F-Feel sick, want you here," Harry slurred. He'd been trying to get rid of his extreme nausea for an hour now, but it seemed it was only getting worse somehow.
"Oh, honey, let's sit you up a little. The bins just on the nightstand, do you think you need it?" Louis asked. He didn't want Harry to be sick again, but if it was going to happen Louis could only hope it took away some of the awful nausea Harry was experiencing. Harry wasn't usually the most stubborn of guys, but he was very adamant that if he drank anything it'd set him off. At this point though, maybe getting sick would be a relief.
Harry didn't make any move toward sitting up in his own so Louis started again. He pushed his arms under him and as gently as possible began shifting upward.
Harry groaned painfully and Louis stopped.
"Doing alright?"
"Lou my tummy feels so ill."
Louis needed to keep moving. If Harry was going to puke-which by the looks of it, he was- Louis needed to get the boy sitting up.
"You need to sit up, love. Just incase," Louis reiterated, getting himself situated before helping Harry off him.
Louis did his best to pull Harry up further as Harry only seemed interested in burying into Louis's side.
Louis leaned temporarily away from Harry to grab the bin, in the short time a confused whimper leaving the ill boy.
"I'm right here," Louis said, wrapping an arm around Harry and coming close again. "Here's the bin, alright? Are you feeling worse?"
Harry burrowed into Louis's side, only a lose arm around the bucket acknowledged it's presence.
"Can't tell," Harry confessed. He didn't know if it was another awful layer of endless nausea or if this was the real thing.
"You should have a sip of water, Haz. You haven't had anything in nearly 2 hours," Louis realized.
Louis was answered in silence.
"After this has passed. You need it," Louis pressed. Niall was physically in worse shape than Harry was, though Harry seemed to be suffering quite a lot. Niall couldn't keep anything in his stomach. Whether he was darting to the bathroom or vomiting everything back up, the boy was sluggish and weak. Nausea was bad on his end too, but it hit in awful waves and Niall was getting far too little back in his system for all he was expelling. A trip to the hospital was looking likely, but Louis didn't want Harry to reach that point too.
Both boys sat in the silence for a few solid minutes. Louis would ask every so often if the nausea had gone down any, but every time Harry  merely shook his head. He looked pitiful; Louis had no doubt about how bad the poor boy was feeling.
Harry was like a statue for minutes when suddenly he was lurching forward with a heave. With how bad the nausea has consistently been, it had come to a surprise even to Harry when a rush of sick met the bin.
Harry gasped and hunched over, his stomach spinning wildly. He'd been cramping up for a while but the heaving had the pain intensified quite a bit.
"There you go, H. Breathe," Louis comforted. He pulled Harry's hair away and rubbed his warm back.
"Oh, my poor thing," Louis cooed, shaking his head as Harry coughed up more of his stomach.
Harry wheezed in a deep breath and swatted at his eyes. He was too sleepy for this.
Harry pulled away and leaned back into Louis, closing his eyes.
Louis began to move the bucket but Harry put a hand on it.
"Sorry...not yet," He mumbled.
Louis smiled sadly and let go, instead enveloping Harry in a hug from behind.
"I'm sorry you're feeling so icky," Louis said quietly. Harry nodded and hummed miserably.
He only lasted another two minutes before his head was back over the bin. Louis winced at the force of it, only hoping Harry would be able to get some rest after this.
Harry retched loudly and let a cry escape him. Everything hurt.
"Breathe, Harry. Just try to catch your breath when you can manage. I've got you," Louis said.
Harry's body was trembling and Louis could feel each pant beneath his hand. Another splash hit the bottom of the bucket.
"Louis," Harry moaned, dragging out the word. He spat multiple times before a burp left him.
"I'm so sorry, darling," Louis tried to comfort.
With a few more shallow heaves Harry pushed the bin away. He closed his eyes and tucked into Louis.
"I can't look, Lou. I-" Harry hiccuped, still looking all too queasy.
"I'll take it away, love. Just rinse your mouth out to get rid of that taste and I'll clean everything."
Louis put a glass to Harry's lips and Harry took a slow gulp. The bin came close to Harry once more and Louis guided him back over it to spit again. They repeated the process a few more times until Harry could barely taste the bitter sick anymore and Louis took both the bucket and glass downstairs.
Louis was alone when he went through the living room to the kitchen. For the second day in a row Niall had been confined to the bathroom for the most part, which meant that's where Liam had been as well. After cleaning out the bucket and refilling Harry's glass of water, Louis went to check on the boys. He needed to get the medicine for Harry from the cabinet too.
Louis came to the door and knocked quietly. Niall would be embarrassed if Louis walked in on him using the bathroom, but he suspected that if Liam was inside the cost was probably clear.
"Come in," Liam answered. Louis followed the order and opened the door. Niall was sat infront of the toilet with his head in his hands as he rested his elbows against the toilet rim. He was as pale as Louis had seen him but as far as Louis could tell the toilet water was clear.
"How is this one fairing?" Louis asked, leaning against the counter.
Liam rubbed his eyes. "Not well. He's feeling worse than yesterday. Aren't you love?" Liam added at the end and looking to Niall.
Niall offered a single nod and scooted even closer to the toilet.
"That's not the direction we were hoping for," Louis sighed. Niall needed a bath too, but everyone was hesitant about that with how often Niall was being ill. Nobody thought that their best bet to get him clean would have been yesterday.
"He's got a pounding headache as well. Can barely keep his eyes open," Liam explained. It was like Niall's symptoms had all been magnified overnight.
Louis and Liam made eye contact. This was getting out of hand, and at some point they were going to have to accept the fact that there might not be anything they can do from the house.
"Louis if this doesn't slow down soon..."
"I know. Harry's on a spiral too and he's too nauseous to move. I'm going to try to get him to drink something but..."
Liam just nodded. Niall sniffled, catching both boy's attention.
"I'm sorry," he cried. "I don't know what's going on o-or why I'm not feeling any b-better. I'm sorry th-that you're stuck taking care of me...I just feel so bad-"
"Woah, Niall. Hey, hey, look at me. It's okay. You don't have any reason to be sorry," Liam cut in. He wiped away Niall's tears. "I'm serious, we're just worried about you."
"None of this is your fault, Niall. Being sick isn't any reason for an apology," Louis added.
Niall sobbed loudly, not seeming to understand. He pitched forward unexpectedly, a rush of stomach contents leaving him and messily meeting the toilet water.
Liam pushed Niall's head a little further down, getting him more on target as Niall shook.
"Niall take a deep breath for me now. You need to calm down, everything's okay," Liam spoke, voice low and soothing. The blonde didn't seem to be registering though.
"Shit, Li," Louis said, not being able to keep his worry out of his voice, "What can I do?"
Liam wove a hand under Niall's shirt to feel his back, quickly putting together the awful heat and Niall's behavior.
"Just a cold-pack wrapped in something and a cold washcloth as well. His fever's getting to him."
Louis ran out of the room for the cold pack and got a bowl of ice water for the washcloth to sit in. He needed to get back to Harry, but this felt like another level of urgency. The thermometer had been left in the living room from when both boys had felt somewhat decent enough to lay down on the sofa and stay awake for longer than 5 minutes, but that phase hadn't lasted long. Louis swiped the device from the table and went back to the bathroom.
Niall wouldn't be able to use the thermometer for a while, as his stomach wouldn't be letting up so soon but Liam was thankful that Louis had grabbed it. They needed to make sure Niall's temperature wasn't getting dangerously high.
Niall was still leaning over the toilet when Louis walked back in, but it seemed like at that point it was the sobbing making Niall gag. Liam coaxed Niall into breathing steadier and slowly had the ill boy lean into his chest. Liam placed the cold washcloth over Niall's neck and held the ice pack against his forehead while Louis scooted the trash can closer to the boys incase Niall's belly revolted again.
"I need to get back to Harry. Are you okay?" Louis asked Liam. This scene was a bit overwhelming but Harry had been alone for a little while now and he still needed medicine.
"Yeah, Lou. I've got him. I'll let you know how high this one's fever is," Liam agreed.
Louis pulled out the medicine he'd come for before rushing back to Harry, remembering to grab the bin.
Harry was curled up on himself when Louis entered the room. He peaked a head up when he heard the older boy enter the room before settling again.
"Where did you go?" Harry asked. Louis hadn't been very long but Harry thought he would only be gone a minute or two.
"I'm sorry for the wait, love. Niall's not doing well," Louis answered. Harry sucked a breath in, his stomach in pain.
"What happened?"
Louis sat down on the edge of the bed and placed a hand on Harry's stomach.
"His fever is getting to him, he's really emotional right now. And he still hasn't been able to keep fluids down," Louis listed, "but it looks like you're in quite some pain, darling. What's going on with your belly?"
Harry tried to relax as Louis rubbed his achy stomach but it was proving to be a difficult task.
"Just hurts," Harry mumbled.
"Can you tell me where?" Louis asked.
Harry dragged Louis's hand a little lower on his stomach before adding some pressure with his own hand.
Louis watched Harry's face twist up and he wanted to stop pushing down, but Harry was the one supplying the pressure.
"Honey it looks like I'm hurting you," Louis sighed.
"No, it's helping," Harry said, "I'm just feeling a bit sick still. It's making me on edge."
Louis nodded, feeling bad that Harry couldn't calm completely.
"Let's try some medicine, yeah? You need some help fighting this thing," Louis said.
Harry moaned and smushed his face into the side of Louis. "I have you to help me fight this thing," he tried. But even his voice was shaky and cracked and did nothing to help his point.
"Let's just give it a go, Styles. It might help," Louis coaxed. He started to pull out the proper dosages.
"It didn't help last time," Harry continued.
"You threw up 10 minutes after you took it last time, Harry. I don't think it had enough time to kick in."
"But Louis-"
"No. You've been ill non-stop for 24 hours, love. You haven't felt well enough to try eating anything and you're bound to be dehydrated. If there was ever a time to take medicine, this would be it. You'll only feel worse if that fever of yours gets higher."
Harry didn't argue. He also didn't make any moves to sit up, but Louis wasn't going to make him move until everything was ready. Louis hated the way any color left in Harry's face drained when he sat upright.
Louis dragged the bin closer just incase after the medicine was ready and wove his fingers through Harry's hair to indicate it was time to move.
Harry scrunched his face up, his bottom lip jutting out in a sad pout. The poor boy didn't want to move a muscle.
"I'm sorry, I wouldn't bother if I didn't think it might help," Louis said softly. Harry drew a hand in to rub his eyes. Sitting up had never felt more a burden.
Slowly, Harry began turning from his side and opened his eyes. He didn't speak a word as Louis helped him up, but slouched sluggishly into the boy's shoulder all the same.
"Let's make this quick, sickie."
In the end, Harry was very compliant. He didn't argue or avoid taking the meds. He only asked for a few seconds between one pill and the next as one went down rather unpleasantly. When Louis went to help him lay back down, though, Harry just shook his head and burrowed into Louis's chest.
"Harry?" Louis asked, unsure about his behavior.
"Love, I don' think they're gonna stay d-down."
Louis sighed and wrapped his arms around his sick boy.
"Aw, honey."
Harry stayed quiet. His mouth was already starting to water but he was trying his hardest not to let Louis down. His eyes were welling up too.
It didn't take another three minutes for Harry to vomit the pills right back up. Louis was shocked at how upset Harry seemed to be before he choked out an apology between retches.
"Oh, no. Harry, it's alright babe. It isn't your fault," Louis hushed him, not wanting Harry to make his stomach sicker with the sobs.
Harry's stomach hurt and so much of him just wanted to feel a little better. It seemed every time he threw up his stomach never stop swirling and his body was heavier with fatigue.
Louis was forced to pull a little away from Harry when he heard his phone vibrating. It took a bit of searching, but eventually he found the device and put it to his ear.
"Hello?"
"Louis, get Harry dressed. We've got to go to the hospital. Niall's fever's too high and he's getting a migraine I think from being dehydrated and we've just got to call it."
Liam was talking quickly and for the first time in the last two days Louis realized he was the calmer of the two. Liam was scared, which meant it was really time to get moving.
"Okay Liam, I'll get Harry ready. We'll be down in a few moments."
Liam agreed and asked Louis to grab an extra set of clothes for the ill blonde. Something warmer but loose, nothing that would make Niall feel constricted.
Unfortunately, Harry was still feeling rather queasy and held the bin close to his side as Louis began to dress him in more layers.
"Lou...what's going on," he mumbled. Louis swiveled to his side for a tissue and wiped Harry's mouth clean.
"We're headed to the hospital, love. Time to get you and Niall feeling better," Louis said, trying to keep his voice light. Harry still looked frightened.
"We need to?" Harry asked. He didn't want to go anywhere, but the hospital was just about the last place he'd happily enter.
"Yes, we need to go. Niall's not faring well, and you're feeling about as miserable as he is," Louis insisted.
Harry frowned and leaned forward into Louis's chest.
"Louis," Harry pleaded. But his body jolted just a bit with a sick burp.
"Honey, you're too ill to argue. But if you need a few moments for your tummy to settle you can have them. I'll get everything ready," Louis shushed.
Harry only crawled up the bed once more and sat against the head board, trash can dragged between his legs. Louis rushed around the room, pulling out the proper clothing for Niall before returning to Harry, whose head was buried into the trash can. Louis cringed at the harsh heave that tore through the younger boy's throat.
Louis came wordlessly to Harry's side and rubbed circles in the center of his back, unsure how else to help.
When Harry resurfaced he asked sadly for his water glass to rinse out his mouth. Louis didn't miss how close to tears he was.
Louis stuffed Niall's extra clothes into a bag before he quickly cleaned Harry's bin of any sick. He wanted it to be clean for the car ride and Harry seemed to be in a sort of daze as Louis moved around.
"I'm going to help you stand, alright? Don't try to move too quick, I know your headache won't fare well," Louis said. He wished he could carry Harry to the car but that just wasn't realistic. He'd just have to take as much weight from the weak boy as he could.
They ended up with Louis's arm around Harry's waist and Harry's arm around Louis's shoulders. Harry had more strength than Louis had expected him to have, but the movement was still torturous on Harry's achy limbs and stomach.
Harry needed to stop at the bottom of the stairs for another round of dry heaving over the bin. Louis peered down the hallway to see Liam walking slowly towards them, Niall limp on his back.
"Car keys?" Louis asked.
Liam looked at Louis gratefully.
"Could you grab them from me? I can't unlock the door like this," Liam asked. Louis agreed and Liam dropped the keys on the floor. Niall didn't stir but Louis still wasn't sure that was because he was asleep.
From the front door Louis unlocked the car. Louis wanted more details about Niall's situation but they'd have time for that on the way.
Liam carried Niall to the SUV parked in the driveway. He helped Niall maneuver into the back seat where he'd have more room to change with Liam's help.
"Hey, blondie. Are you still with me?" Liam asked, hands on either side of Niall's face.
Niall nodded a little.
"Can you tell me where we're going?" Liam asked. Niall didn't seem too coherent.
"Hospital," Niall moaned.
Liam nodded to himself, thankful Niall remembered.
Niall have Liam's wrist a small squeeze. God, he felt so weak.
"No needles?" Niall asked. His slurring words kept Liam's heart rate up.
"I can't promise you that, darling. I'll be with you though, okay?"
"Okay."
The car ride was nothing short of miserable for all parties. Niall spent the beginning of the ride half asleep, but the twisting road got the better of him before long. Liam saw it coming easily, but Niall's vomiting wasn't helping anyone's nerves. The small amount of blood that came up was alarming as well to say the least.
"It's probably your throat, darling," Liam comforted, but that didn't help much.
Harry on the other hand didn't get 5 minutes before he was quietly heaving. He was bent over the dashboard the whole trip, the trash can sitting by his feet. Louis pulled over when Harry broke down and lead the poorly boy from the car. Harry was crying hard.
"I-I feel faint, Louis," Harry managed. Louis had him sit down in the grass away from the edge of the road and tuck his head between his knees. Harry's stomach finally managed to get something out, but Harry's body was so tired Louis had to keep the boy from slumping over.
Fortunately, once Louis helped Harry's tears subside, Harry was too exhausted to keep awake the rest of the drive. They made it the rest of the way without any more trouble.
Once at the hospital, the four boys sat together in the waiting room. Louis and Liam did their best to fill out the medical forms that were required, but Harry and Niall were barely any help in their conditions. Niall was taken back first, which was no surprise. He'd pretty much sealed the deal when he got up to use the restroom and nearly blacked out on the spot, only Liam and Lou's sturdy hands thwarting the collapse.
Harry luckily didn't have to wait long after, not that it seemed to make much difference. Harry couldn't keep his eyes open no matter how hard he tried. He was completely sacked out against Louis through the wait.
Niall, as suspected, was awfully dehydrated and had messed his throat lining up from being constantly ill.  And with his stomach still sick and unsettled, an IV was going to have to be used to help.
"Niall, you'll barely feel it. Just try to stay still and relax, it'll just last for a moment," Liam murmured. Niall was breathing heavy though. He wasn't a fan of needles in the slightest and his heart was hammering.
"Hey, look at me. They're going to put it in, okay? And you're gonna be just fine. Hey! Watch me, love, just keep those eyes on me," Liam said, not wanting Niall to flinch at the on coming needle. He could do this.
Harry needed an IV too, but he was too sleepy to understand most of what was happening. The lighting in the hospital was doing something awful to Harry's headache, but once the IV began flowing his aches and pains seemed to subside. As Louis had guessed, being dehydrated had made everything feel much worse.
With Niall's fever so high and Harry's on the rise, the boys needed to stay overnight. Neither Louis nor Liam were very surprised by this, but in the rush they both forgot a change of clothes for themselves.
Harry and Niall were released by noon the next day. They were still rather unwell and definitely exhausted, but they were much better after their night with an IV. It took another two days of recovery for either boy to feel up to more than laying around in bed all day, and their appetites were still nowhere to be found, but Liam and Louis were thankful to see the obvious improvements. After the panicked days they all had, a few more days in bed would do them all well.
