I don't own Percy Jackson or any of the avengers!
Steve's POV
The day after Percy found out he gets to stay
Percy reaction to when I told him he gets to stay was adorable. He flung himself at me and started hugging the life of of me. I also think he may have been crying and that surprised me because he wanted to stay that bad. I mean, I know he likes it here but I didn't know that much.

The team and I were all eating breakfast but Percy never came down. He never stays in bed this late and I was starting to worry. When he did finally come down I was about to breath in relief but didn't when I saw his appearance. His messy black hair is messier than usual. His green eyes look duller and have bags under them. He looked like he was sweating and shivering at the same time, and his nose and ears were bright pink. He's sick.

All of us quickly ran up to him and I picked him up and brought him back to his room. I put him on the bed and Bruce immediately came over with a thermometer, and gently stuck it under Percy's tonnage. After about thirty seconds he took it out and showed it to me.

103.
Shoot.

Percy's POV
When I woke up this morning I felt horrible. I thought of it as just a little cold but found out it was much worse when I walked down all of the stairs to get to the kitchen. I was shaking from being cold yet sweating from being to hot. All of the avengers looked at me then rushed towards me and brought me to my room.

When I got to my room Bruce put a thermometer under my tongue and everyone waited until it beeped. He took it out and I kind of zoned out trying to put a sheet on me so I wasn't so cold but not to hot. When I was back to reality everyone was talking in hushed whispers but I could still here them. "If it gets a degree higher we have to put him in an ice bath. I don't want to but it's the only thing that will bring is temperature down." Bruce said. An ice bath sounded good and bad right now. But mostly good. "Will he be okay until then?" Steve asked. "Well as good as you can be when you have a high temperature."

Natasha went downstairs and appeared back with a thing of soup in her hands. She gently handed it to me and I said, "Thanks." As loudly as I could. She nodded looking at me with kind eyes. I ate a little broth and it was really good, but as soon as I ate a piece of chicken everything came right back up. I got up as quick as I could and ran into the bathroom. Steve followed me and as I was leaning over the toilet he rubbed my back saying soothing things to me.

When I was finally done I just layed on the floor and closed my eyes. I felt Steve pick me up and I soon fell asleep.

When I woke up I looked at the clock and it was two hours later. If possible I felt even worse than before. For a few minutes I just sat there and stared at the wall, when finally Bruce and Steve walked in. "Can I take your temperature we need to make sure it didn't go up?"

When it was finally done they told me that it was at 105 degrees and that I needed to take an ice bath. The ice bath didn't sound as appealing as it did before and I was dreading to go into, but I'm not weak I'll do it and then I'll feel better so we can have a lot more fun together.

Steve picked me up and brought to Bruce's lab which had a little infirmary in it. They already had the bath set up and said that I could wear my pajamas which made me happy because I love my pajamas.

When Steve set me inside of it my whole body started to tremble from the coldness of it. When I said I wasn't weak before, I feel like I am now. I looked at Steve and he looked back at me with sadness in his eyes.

Steve's POV
When I set Percy in the ice bath he started trembling and looked up at me with big eyes. I looked down with sadness. When five minutes were finally up I reached down and brought Percy out of the ice bath. He was shaking, his lips were blue, and his teeth were chattering. I wrapped him in a big warm blanket, even though he was wet, and picked him up.

As I was walking back I had a sense of De javu because Percy fell asleep in my arms once again. When we got to his room I lied him down and tucked him, then kissed his forehead and walked out.
