Steve: "Steeeeeeeeeve..." you groaned from your bed. You heard scurrying footsteps to your door and Steve appeared, holding a towel around himself. "What? Are you okay? Woah, you look pretty crappy." he said from the doorway. "I think it's strep throat." you murmured. "Oh, that's the worst. I'll be right back, Sweetheart, I'll go tell Coulson I can't make it today."
"But you-" you paused to cough, "you can make it." Steve simply smiled and ran off. You quietly whimpered- you needed water desperately, but felt bed ridden. Nearly ten minutes later, Steve came in, arms full of water bottles, candy, any junk food he could find. "Is this okay? And I can set up Netflix, or whatever you need." he plopped down on the King-sized bed beside you, dropping all the stuff with him on the duvet. You immediately grabbed for a Twix bar and a water bottle. He was at your side the whole day, and most of the night. (He didn't worry about catching it with the Serum.) The next day, you woke up, throat almost completely better. "Thanks, Steve." you whispered, placing your head on his chest.

Tony: "Ton-" you interrupted your self by throwing up your guts into the toilet bowl again. "What's wrong, Babe...? Oh..." Tony walked in and almost immediately backed up a little. He was terrified of getting sick. "Can I have... Water or something?" you gasped breathlessly, before throwing up again. Tony made a small squeak. "Yeah, yeah, of course... Anything you want." he ran off, and you hoarsely laughed. How Tony hadn't known you were sick before you called him in, you didn't know, but you knew he wouldn't be touching you at all until you were healthy, because that happened every time you were sick. He went and got you everything you wanted, but if you asked him for hugs, he had an excuse to leave the room.

Bruce: "Bruce? Can you help me find my medicine? I think I lost it... And it was really expensive." Bruce's smile immediately faded. "Medication? You're sick? What's wrong? Why didn't you tell me?" he came over to you, absentmindedly checking things like your fever and pulse, both of which were fine. "Softie, I'm fine. It's just an ear infection, but it really hurts and I need my antibiotics... And probably some pain meds." you smiled, and got down on the floor, looking for the orange bottle. Bruce got down, too, and after awhile, you found it wedged between the couch and the wall. Bruce got you everything you needed, from a blanket to chick flicks, and was basically the best boyfriend ever.

Clint: Oh, why? Today of all days, you had to get a stomach bug, and Clint wasn't even there to make it feel better. You threw up for the millionth time, and upon hearing your iPhone chime, you left the trash can for a quick second. "Hey Pee- whoa, are you okay? You look a little..." Clint pondered, his face inching towards the screen. "Sick? Yeah, pretty..." you paused to spit out the bile infested saliva in your mouth. "Much so. I wish you were here." you continued, wiping your face with a wet towel. "Well, I was actually calling to tell you that I was coming home early... Good thing I am, because from the looks of it, you'll be like that for awhile. I'll be at your house in a couple hours, okay?"
"Alrighty. I'll try not to-" you threw up yet again. "To throw up my organs before you get here. Love you, Katniss."
"And you Peeta." he blew you an air kiss and ended the FaceTime. It was going to be a very long couple of hours.

Thor: "Ah, crap."
The although quite delectable meal you'd just shared with your boyfriend must have had (food you're allergic to) in it. You'd developed a very red and extremely itchy rash that you knew was caused by the food. "Milady, are you alright? You seem to be scratching a huge amount." Thor asked, obviously concerned. "It's from the (same food). I'm allergic- this happens every time I eat it, and I really need to go home and take something to fix it." you explained. A sad look appeared on his face. "But of course. I shall take you home and help you with whatever you need. Let us go." Thor said, taking your hand to lead you back home, where he did as he said he would. He got you everything you needed, rubbed medicine on your rash, basically everything that you normally would've done yourself. "Thanks, Thor."
"Anything for you."

Loki: "Lokiiiiiiiiiiiii!" you called through the halls of the huge castle that once again, you'd gotten lost in. Loki had brought you to Asgard to meet Frigga and Odin, and today was your last day. And unfortunately, your immune system must hate you, because you had woken up with a raging sinus infection. "LOKI!" you yelled. "In here, Y/N." His voice sounded like a whisper. You followed it, since it hurt so much you couldn't force him to come with your power. "Oh, there you are. Thank goodness. I have a sinus infection, and I need you to fix it. And don't tell me you can't do that sort of thing, I know you can." you demanded once you reached him. He looked up from his book at you. "Why of course, my Queen." he whispered. And suddenly it was gone. A sigh of relief escaped your lips and it was then you realized where you were. He'd been in his chambers the whole time, as he was now, and yours were right next to his. "You jerk." you whispered on your way out, and he smiled slyly.

Bucky: You sneezed into a tissue, disgusting yourself at the amount of snot. "Hey, Firecracker, what's going on?" Bucky said as he walked into your room. You were curled up under about ten blankets and took them on and off every other minute. "Cold." you whispered. "Ah, baby, I'm sorry." he came up to you and started rubbing your back. You sniffed, and Bucky handed you a tissue. "I'm your worker for the day. What would you like, miss?" he said, causing you to giggle. "Water. And softer tissues, these hurt my nose." you smiled to yourself. "Coming right up, ma'am." he left for a minute, and came back with exactly what you asked for. You sneezed yet again. "Bless you."
"No, bless you. I love you, and thank you for doing this even though you don't have to." you whispered, blowing your nose in between words.
"But of course I have to. I mean, then you'll do it for me when I get sick."
"I'd have done it anyways, idiot." you giggled, going in for a quick kiss on the cheek. Bucky held you back. "Nuh uh, not until you're all better." he said, booping your nose.
