It had been six days…

Six days since Jemma had jumped. Six days since she had contracted the alien virus. Six days since he nearly lost her.

That wasn't going to happen again. He made a promise to her that he was going to protect her. He had failed once, he wouldn't do it again.

Fitz spent those past six days locked away in the lab, still going to check on her occasionally. She wasn't allowed in the lab until they were sure the virus was gone. He had no choice but to stay in that lab, however. He had a project that he needed to finish as soon as possible. He wasn't going to break that promise again and this new project was going to help him keep it.

He let out a sigh as he tightened a loose bolt on the mechanism inside. That should be the final part. The project should be finished. After multiple failed trials, it should finally work.

Fitz stood back and looked around, trying to find something to trigger it. His eyes widened as he found a stray roll of duct tape. He quickly tore a piece of the silver tape off and walked back over to the small machine. "Let's hope this works." He muttered before sticking the tape on his arm and ripping it off. He let out a quiet 'ow!' as the tape was quickly ripped off, leaving his skin quite red.

A puff of air turned his attention from his arm that he was sure was bleeding, to the machine in front of him. What was a small red box before was now a big white balloon shape with two black eyes. It blinked and slowly waddled out of the box, carefully making its way to him. "Hello." It said, offering him a wave. "I am Baymax, your personal healthcare companion. I heard a sound of distress. On a scale of 1-10 how would you rate your pain?" It asked. Fitz looked down at his arms and shrugged. "Um... Three?" He spoke, trying to guess the closest number to where the actual pain was.

"I will scan you now." The robot said calmly. Fitz felt a huge smile spread across his lips. It was working. He had gotten to this part before but it seemed like it was actually working this time. Baymax quickly performed his scan. "Scan complete. You have an abrasion on your lower left arm."

It was working. His robot was actually working. Fitz must have stood there, simply staring at it, for a couple of minutes before remembering to actually respond to it. Baymax took his arm and quickly sprayed a soft mist along where the duct tape had been. "The anti-bacterial spray has been applied." He looked down at his arm that was already feeling a little better. "Thank you, Baymax."

The white robot blinked again, staring down at Fitz. "I cannot deactivate until you say that you are satisfied with your care." He nodded. "Right! I am satisfied with my care." Fitz said, crossing his arms as he watched Baymax waddle back to the red box and slowly deflate.

It worked. His project worked! Now he could keep Jemma safe. He wouldn't have to worry about her being alone or in trouble. Baymax would be there for her. With a content sigh, Fitz pushed Baymax's suitcase as he called it, into the closet. He would have to go get Jemma to show her what he had done.

Jemma was in her bunk, sleeping off the last of a bad headache. She'd had yet another nightmare and this one left her with a splitting headache. She groaned as she buried her face back into the pillow, trying to block out as much of the offending light as she could. It wasn't helping very much.

With a defeated sigh, she got up slowly and decided to go to the kitchen. Maybe some tea would help. Grabbing her duvet for added comfort, she made her way to the kitchen to brew up some tea that would hopefully make the remains of the headache disappear.

She hadn't expected to nearly run into Fitz on her way, however. He was running down the hall to who knows where and nearly plowed into her as they were crossing the same intersection. "Fitz!" She said loudly. "What's the matter?" She asked, turning to fully face him.

He scratched the back of his neck, now very sorry that he was in such a rush. "Sorry, Jem… it's just that I need to show you something. It's important." She sighed. "It can't wait until I get a cuppa? My head still hurts quite badly." Fitz shook his head. "No, it can wait. In fact, let me go boil the water. You go sit on the couch." He said, now very worried for her. Normally she wouldn't complain if her head hurt which meant that it hurt her a lot.

Simmons reluctantly sat down on the couch, curling up under her comforter, which she was very glad she had brought. Fitz normally never offered to make her tea. They normally did it together but he understood her pain. She didn't get like this often. It didn't take Fitz long to make the tea either. Within five minutes he had two cups in his hand and was quickly making his way back to the couch.

Jemma couldn't help but smile as he handed her the cup. "Thank you, Fitz. Really, this means a lot." They sat and drank their tea, occasionally speaking to one another. Once both of their cups were empty and on the table, Simmons sat up. "Alright, so what did you want to show me?" He got up quickly and held his hand out for her to take. "I have been working quite hard on something that I think can help a lot of people… especially you."

With a bit of hesitation, she took his hand and stood up, slowly following him to the lab. He was being very vague… She was actually quite nervous! "Alright, so something that helps people do what exactly? Also… why me?" Fitz just shook his head. "Trust me, you will see when we get there."

He wasn't trying to rush her, it just happened. When they actually reached the lab, Jemma had a hand on her head. "Ow… Fitz slow down, my head won't let me go that fast." He had a smile on his lips as the little red box in the corner started to beep. She looked up, trying to find the annoying beeping sound, only to be greeted by a giant white balloon… thing. "What the-" She started, staring at the robot in front of her.

Baymax slowly made his way towards Jemma, having to push a stool out of the way before he finally made it to her. "Hello. I am Baymax, your personal healthcare provider. I was alerted when you said 'ow'. On a scale of one to ten, how would you rate your pain?" A big smile broke out across Jemma's face. "Fitz… this is amazing." He chuckled. "Jem, you have to answer."

"Oh right, sorry! Um… I would say a 7." She spoke truthfully, not wanting to mess anything up. Fitz had done quite an impressive thing here with this robot, might as well see what it can do. "I will scan you now." It spoke as it quickly looked Simmons up and down. "Scan complete. You show symptoms of a migraine. I would suggest sleep in a dark room and heat applied to your head and neck." Jemma nodded. "Very nice. I think I will do just that." The robot only blinked. "You are also showing symptoms of depression and anxiety." She froze. Depression and anxiety? She wouldn't doubt it. She had been showing signs of it as she hadn't really left her room, she didn't want to eat, the nightmares… it made since.

"I would prescribe a close friend to help you through it. Also, a couple pills a day to keep the serotonin levels from dropping." He held out his hand and a little see-through bottle popped out that housed quite a few small white pills. Simmons took them from Baymax before looking up at him and nodded. "Thanks," she turned to Fitz. "I think I will do just that."

"I cannot deactivate until you say you are satisfied with your care." Jemma nodded again before speaking up. "Right, I am satisfied with my care." Baymax slowly nodded in her direction. "Goodnight Jemma." She watched as it made its way back to his travelling case. "Fitz, I…" She didn't know what to say. The robot knew her name… it knew her symptoms and what exactly was wrong with her before she did.

Fitz just shook his head. "I made Baymax to protect you. I can't lose you, Jem. The danger of being a field agent became too surreal when you fell out of this plane. I had to do something." A sniffle was heard coming from Jemma's direction. He had made her cry?! "Jem… are you okay? Did I do something wrong? Talk to me, lass." It was a blur of motion and all of a sudden, she was holding onto him as tightly as she could. He wrapped his arms around her waist and held her close, burying his nose into her neck.

"No… this is the sweetest thing anyone has ever done for me." She whimpered, pulling him closer if it was even possible. "Thank you, Leo. Really, it's amazing." He couldn't help the huge grin that spread across his lips. It had worked and she had liked it… He was going to be able to protect her now, no matter what. He tightened his grip around her waist and let out a sigh.

Everything was going to be okay.

A/N: I am so sorry for that ending first off. My mind stopped working really. Anyways, this is a prompt that popped into my head last month and I finally decided to write it! I love the idea of Fitz creating Baymax to protect Jemma really. It just kinda works... Anyways! I am in need of more prompts to write as I do want to keep writing. Please leave a review! Thank you as always.
