Shiro: 

Him- When he's sick, he refuses to stop working, even when he has the flu or any other bad sickness. He has to be space dad 24/7. Whenever you see him out of bed, working on something, you literally drag him back to his room. You give him his medicine without any complaint from him. You take on all his responsibilities (other than flying Black of course) when he is resting and recovering. 

You- When you are sick, Shiro builds you a nest of blankets to make sure you're comfortable, knowing that he is going to make you stay in bed all day. He gets Hunk to help him make you soup. He doesn't entirely trust his cooking skills so he needs assistance. He always checks on your health when he's not doing something and checking to see if you need anything. 

Keith:

Him- When he is sick, he tries to walk it off. You stay with him all day to keep an eye on his condition and to make sure he doesn't do anything to make him even sicker. Trainings a big no. You don't want him battling a gladiator when he's barely functional. He keeps trying though.

You- When you are sick, Keith freaks out because he's never had to care for a sick person and you rarely get sick. He gathers tips from the rest of the paladins on how to help you. He makes you soup, keeps you hydrated, and everything! Once he does everything that he knows, he cuddles with you in your pile of blankets and watches movies with you on a device that Pidge made. 

Lance:

Him- When Lance is sick, he exaggerates it. He even gives you the whole "if I don't make it" speech. You of course don't believe him and just force him to take medicine and bring him water and soup. You eventually cuddle with him when he wouldn't let go of your hand. This at least got him to fall asleep and stop complaining.

You- When you get sick, Lance goes all out. He is on top of everything! A single sneeze has him rushing to find every tissue in the ship. He even has Hunk make all the types of soup known to man kind. He doesn't dare step into the kitchen. This boy can burn water.

Hunk:

Him- When sick, Hunk isolates himself in fear of spreading the sickness. He only lets people in if they need to ask him something, are bringing him food or water, or if they need him for Voltron. He lets you in the most though. You give him cuddles. You are the one making his food and giving him his medicine.

You- Hunk is constantly by your side when you get sick. He's like a puppy and its adorable. He carries you to the kitchen when you need to eat and he feeds you. Protect this boy! He cuddles and watches movies with you until you fall asleep in each others arms -w-

Matt:

Him- When he is sick, he refuses to get out of bed for anything. He's just so cozy in there and he doesn't want to get anyone else sick. You never had to care for anyone being sick so you ask him what he needs and he tells you. You also look for certain remedies for his sickness. You don't really know what you're doing but you are trying your best so that's all that matters :0

You- Matt had taken care of Katie whenever she got sick so he knows exactly what to do. He wraps you in blankets and tends to your needs. Wether it's food, water, or cuddles, he's there to give them to you 

A/N: My sister has been a little sick lately so I wanted to write this because it's a good scenario :)
