Work Text:
You were surprised to have been called to the med bay a little bit past nine in the evening, woken up by your phone ringing and Ratchet on the other end. You clutched your robe close to your body as you raced through the hallway, sleep in your eyes and worries in your head.
The lead medic had given you no explanation, only telling you to come meet him outside of the med bay as soon as you could before he hung up on you.
You wondered if it was an emergency, if someone was injured or dying, if something had happened during patrol- Wait, no. Their night patrols didn’t start for another hour or so, and if it had been an emergency, someone like Bumblebee or Optimus would’ve called you in a panic.
Still, the whole situation was weird, and you were worried, so when you saw Ratchet outside of the med bay leaning against one of the walls, you immediately approached him with your concern etched in your features.
Upon seeing you, Ratchet stood up straight, then put a strong servo on your shoulder in a reassuring manner before looking down at you. His pale blue optics burned into your (e/c) eyes, and though you tried your best, you couldn’t read his expression.
Finally, after what felt like forever, the medic spoke.
“Optimus Prime has fallen ill.”
“What?” You immediately sputtered, and your eyes flew to the door of the med bay; closed, you couldn’t even see Optimus. You just prayed that he was okay. In the time that you’d known the Prime and his team, you’d seen him injured or sick plenty, though the former was much more common. He never prioritized his own health and tried to push himself to do things, even when he was unwell, so he took forever to recover... Hopefully it wasn’t something severe. “How bad is it? Is he awake? Have you told the team yet?”
“Hey, hey, slow down. It’s nothing crazy, (y/n), so don’t worry,” Ratchet’s words, said in an uncharacteristically gentle tone, soothed you, if only a little. If it were serious or ‘crazy’ as he put it, he would’ve told you directly instead of lying, so you believed him. “This morning, I was the first to wake and go into the kitchen to make myself an energy booster when I saw him stumble in... As in, he was literally stumbling over himself and I could see steam rolling off of him from overheat. He insisted he was fine, but something was off, so I dragged him to the medbay for testing. He’s low on energon and coolant, he was overheating, and there was a minor glitch in his vents from some battle damage that I had to fix. He’s recovering fine, but my main concern is that his chassis seems to be overheating to kill an infection. I think it’s just your run-of-the-mill space bug based on the labs I did, so I gave him some antibiotics.”
“You didn’t answer some of my questions-” You started, now concerned with whether you could actually go and see Optimus or not.
It wasn’t uncommon for the red and blue bot to ignore his own needs, but for him to have ignored symptoms that could’ve turned into something much worse had Ratchet not caught them... You wondered if there was something bothering Optimus that was making him neglect himself, more than he usually would.
“So demanding, you youngin’s,” Ratchet huffed and rolled his optics at you. “It’s not that bad, he’s awake, and no, I haven’t told the others yet. Our nightly patrol is soon and I have to break the news to them somehow, which is why I called you here. You can’t go with us anyway and they need me since we’re down one bot, so I want you to stay with Prime. He responds the best to you...” You blinked and then blushed at that, (s/c) cheeks burning bright. It was true that you and Optimus were close, but for Ratchet to acknowledge it like that... Well, you were flattered. You’d loved Optimus for as long as you could remember, and even though Ratchet surely meant that in a platonic way, it was nice to know that the effort you put into your relationship with the bot meant something. “His condition isn’t from a decline in his physical health- I had to pry like hell to find out what it was, but Prime finally broke and told me that he couldn’t remember the last time he’d eaten an energon cube or ran a self-evaluation to make sure he was functioning properly, which is why he’s energy-depleted and why the damage to his vents went unchecked. He’s so stressed from the leadership that this team needs that he isn’t taking care of himself anymore, and now, it’s led to him falling sick again. I think there’s something else going on in that processor of his, too, but he wouldn’t tell me anything else... I just know it’s more mental than anything.”
You stopped, frowning. What else could Optimus be hiding from everyone? Was he doing something dangerous? Had something happened? Was he breaking down from stress?
“O-Oh.. Okay,” You mumbled and leaned into the servo of Ratchet’s that was on your shoulder, sighing when he ran his thumb over a sore spot on the groove between said shoulder and your collar. The two of you had developed a close bond over the past couple years since they’d been on earth, with you, Sari’s tutor and caretaker, also acting as a second medic for the team with Ratchet’s training. While he’d trained you in how to care for the Autobots, you’d given him the basics of human anatomy and medical care, so with that time spent together, you were close- whether the old grump admitted it or not. “What about his medicine? How often does he take it? Is there anything else I need to do?”
“One pill every six human hours, they’re the white gel capsules that are rationed out on the table by Prime’s med-berth. I just gave him a dose, so don’t get him another one until three in the morning. He also needs to drink plenty of energon, coolant, and lubricant to get better, so make him do it, even if he gets pissy with you- shove it down his throat if you have to... But those are all things that I already told him, and he’s fully capable of taking care of himself. I don’t need you in there to take care of him so much as I need you to stay in there to make sure he doesn’t get up and do anything stupid. You know how he gets when he’s sick.”
“Unfortunately, I do...” You let out a long sigh and crossed your arms over your chest. It was going to be hard dealing with Optimus- hell, you could already imagine how he would be trying to sneak out of the med bay to go on patrol or trying to make you bring paperwork for him to do. You wouldn’t allow either, but considering how much larger he was than you, you’d have to convince him to relax instead of just being able to hold his aft down like Ratchet or Bulkhead could. “I’ll make sure he stays put. I’m assuming you’re taking over leadership until he recovers, Ratchet?”
“As the team medic, I’m second in command, so yeah... I have to. I’d let Prowl do it, but Primus knows he doesn’t want to, and I wouldn’t let Bumblebee or Bulkhead within a ten mile radius of any form of responsibility like this. I’m really the only option.”
“Right...” You imagined what a patrol without Optimus, led by a stressed and grouchy Ratchet would be like, and then cringed. “Good luck.”
“Thanks. I’ll need it.”
With that, Ratchet withdrew his servo from your shoulder and waved at you before turning around and walking down the hallway. You figured that Optimus shouldn’t be left alone for too long, so you quickly entered the med bay and shut the door behind you.
It was dark, with a small night light plugged into the walls that illuminated the room just a bit. You could see Optimus, who looked uncharacteristically pathetic, weakly laying on a med berth with a small side table on the ground next to him. On the table were some energon sticks, a cup of coolant, and the white pills that Ratchet had mentioned.
“(y/n), is that you?” Optimus asked, trying to sit up, but immediately groaning in what you assumed was pain and flopping back down. His eyes squeezed shut, a strained grimace taking over his face-plates. You pulled one of the stools by a wall-counter to the side of the room where Optimus’s berth was and put it right by his side table so you could sit by him. You were close to his face, so you leaned down to look at it as his optics slowly opened back.
He was sick, and it would take at least a few days if not a week to recover; you could tell just by looking at him. His ocean-hued optics were abnormally dark and foggy, his powder blue faceplates were stained dark with heat, and though he wasn’t steaming like Ratchet had described this morning, there was definitely still heat radiating from his frame.
“Yes, Optimus, it’s me... I’m here to watch over you,” You leaned in to kiss the top of his helm, able to feel just how hot the metal felt against you. When you pulled back, you frowned at the absurd amount of heat- almost hot enough to make your lips sting, while Optimus’s normal temperature was a bit cooler than that of an average human’s by a degree or two. “Ratchet called me down here and told me what’s going on a bit ago. The team’s on patrol right now.”
“Slag, I can’t believe Ratchet told you,” Optimus groaned again, this time in annoyance instead of pain. “I told him not to earlier when he was fixing my vents... He’s probably going to tell the rest of the team, too. I have to get up and go supervise the patrol-” He forced himself to sit up this time, forced back a wince, forced his optics to open fully, but the second you pressed a rushed hand to his chest plates and attempted to push him back, he froze.
“Oh, no you don’t!” You argued, eyebrows furrowing in frustration as a pout formed on your face.
“Oh, yes I do!” The Autobot argued back without hesitation, but didn’t actually move to push your hand away or leave even though he was fully capable of doing so, only resting one of his servos on the one of yours that was on his chest- stumbling and overheating or not, he was much larger and much stronger than you. Then again, he probably knew that Ratchet would beat him to a pulp the second he recovered if he dared lay a single digit on you to escape the med bay. “As much as I appreciate the concern, I don’t want it nor do I need it, and I certainly don’t want it from my team. It’s bad enough that you know. I know they’ll start asking questions when I don’t go on patrol with them, and if they hear that I got sick from overexerting myself and not getting enough rest and energon, they’ll never let me hear the end of it-”
“Well, maybe that’s what you need, so lay your stubborn ass down! I did not come here with my hair all fucked up and in this stupid robe in the middle of the night when I could’ve been sleeping just to have you run away from me when I’m trying to take care of you! You getting up right now just drives home how bad you are about prioritizing yourself,” Optimus’s plump and normally soft lips, now chapped from dehydration, pulled together into a tight frown- it was the face he made when he knew he was in the wrong. “You’re getting out of your bed when you’re supposed to be resting so you can go lie to your team and tell them you’re fine when you’re not, and for what? Your pride?”
“No, I just don’t want them to worry for me. I’m already stressed out enough and the last thing I need is for that to contribute to their struggles. They’re all dealing with so many of their own problems, and I’m sick of being a burden to everyone around me...”
Optimus huffed, but gave up and laid back down, much to your relief. He still held your hand, though, and you let him- even if he was sick, you didn’t want him to let go.
“You’re not a burden, and just like how they’re dealing with their problems, you’re dealing with yours. You don’t have to be perfect to be loved and respected, and not to insult your acting skills, but... They won’t believe you if you walk out there overheating and struggling to stay standing to tell them that you’re perfectly fine. Ratchet told me how you were stumbling around this morning.”
“I hate that you’re right,” He mumbled, and you wondered why he always had to be so childish when he was sick.
Then again, as much as you hated Optimus’s stubborn personality, it was a major component of who you’d gone and fallen in love with all that time ago. It was crazy, you thought; just the extent that you loved Optimus Prime to, and how terribly unaware he was of it. You thought it best to keep the fact hidden, as you didn’t know what his feelings were, and he had so much on his plate already... It hurt to think that he didn’t know how loved he was- not just by you, but by everyone around him, who he was always bending over backwards for, completely unaware that they’d do the exact same for him.
“And I hate that you treat yourself like this. Plus, as much as Ratchet threatens us all with consequences for our actions, he’s not going to tell them what’s going on in depth; just that you have a fever and that you’re resting, you know he respects patient confidentiality. He’ll probably even downplay it because he knows that’s what’ll make you happy.”
“No, you’re just trying to reassure me, but...” Optimus paused and let go of your hand, fully settling back into the berth. You took your hand back and looked off to the side, already missing his touch. “I know you want to, and that Ratchet probably told you to spend the night here and take care of me, but I’m alright now. I’ll stay and rest, I promise. You can go to your room to sleep, I know you’re usually not up this late, and I’d hate to keep you up with my problems.”
You didn’t really want to leave him, but you were tired, and you believed his words. His tone was genuine enough.
“Are you sure?” You asked and received a nod in return. So, you stood up and collected yourself. “Okay, if you’re sure... I’ll leave and go get some rest, then come back at three to give you your antibiotics and make sure you’ve got something on your stomach.”
Silence.
The second you turned around to leave, though, Optimus was grabbing the back of your robe and holding the cloth between his digits, tone low as he spoke again.
“Actually, (y/n), wait... Don’t leave me. I need you.”
You turned back around and looked at him, confused. Hadn’t he just told you seconds before that he was fine and that you should leave to go get some rest so that he could fall into recharge as well? What was with the sudden change of heart? Was there something going on with his physical condition, or was it something else?
“Huh? But Optimus, you said you needed to rest...” You muttered, which earned you a shake of his head in return.
“I will,” Optimus promised. “Please, just stay and don’t question it. I lied to you, I don’t know why, but I can’t be alone right now. Don’t leave me.”
The plead from him was unexpectedly vulnerable, honest, open. You appreciated it, but at the same time, you were concerned about what exactly was going on with him- you felt like there was more to the story than stress and leadership and lack of self-care. While all of that was definitely in character for Optimus Prime, there was something else that he wasn’t telling you about, too. With how close you were to him, it wasn’t abnormal for you to have deeper discussions, but for him to admit that he wanted- no, needed you there with him and couldn’t be alone was something you’d never thought you’d hear in your lifetime.
“Okay, I’ll stay until you tell me to go, then. Thank you for being honest with me.”
With that, you sat back down on the stool and looked at him. A little bit of that light had returned to his optics, but he still seemed like he was in rough shape.
“Thank you.”
Silence again.
Instead of adjusting to get comfortable and slip into recharge, Optimus just sat there with his back against the board of the berth, optics trained on you. It had taken a while to get used to when you’d first met him, but nowadays, you were used to the Prime’s intensity, especially when it came to eye/optic-contact. Still, though, the way he was staring at you now... You couldn’t quite interpret it. Then again, could you usually? Optimus was hard to read sometimes.
“You’re not resting,” You teased, but received a serious response in return.
“I’m thinking, and then I’ll rest.”
“You’re sick, the last thing you need to be doing is overthinking like you always do,” You reached out to him, rested your palm on the side of his face and tenderly ran a thumb over the apex of his cheek. Surprisingly, he leaned into your touch with a smile.
“What if it pertains to you? It’s either I tell you and get my closure, which is daunting, or I sit here overthinking it like I always do.”
You felt your heart drop to the bottom of your stomach and flinched. It had been obvious that something was on his processor, but it had to do with you? What was it? Did it have to do with your feelings? Tense, you talked again.
“...Have I done something? I’d rather you tell me.”
“You’ve made me fall in love with you.”
The words were whispered but still felt so loud, filling the room with their impact in a way that made your cheeks hot and your heart beat hard against your chest.
“Your illness must be making you delusional,” You laughed nervously, but Optimus only gave you a sloppy grin and laughed. You moved your hand to the top of his helm to check his temperature, but it hadn’t changed- as much as you wanted to believe it, you were sure he was being serious and not having feverous hallucinations like you’d initially suspected. Still, you thought it proper to ask. “Do you feel hot? Are you overheating again?”
“No, (y/n), I’m just in love with you,” Optimus peered at you, smile falling a bit. “I mean, yes, I am sick, and I’m still overheating, but I’ve been in love with you for- Ah, I’m actually not sure how long it’s been... I just know it’s been too long.”
There was a pause, in which the two of you seemed to be processing what important things were said; in the span of just a minute or two, Optimus had boldly laid his feelings out for you on the table, unabashed and proud, the tension that came with two years worth of pining that you’d been doing solved so... Quickly. You were surprised you hadn’t felt your jaw hit the floor.
Had he really loved you the whole time? Or was this a recent development? Why was he only telling you now? Had his stress over his feelings for you also contributed to his sickness?
“I’m not sure I can talk about this in good conscience when you’re so vulnerable,” You smiled back at him, (e/c) eyes meeting his ocean-hued optics as you removed your hand from his head. Shyly, he reached out to tuck a strand of your hair behind your ear. “It feels selfish, but... I love you, too, and that’s why I want you to rest and get better, maybe not stress out so much.”
You kissed the back of his servo as he pulled it away, earning what you hoped was a blush and not more symptoms of overheating.
“I’d kiss you if I weren’t afraid of getting you sick,” Optimus sighed. You were sure that you probably couldn’t catch whatever he had going on since he was a Cybertronian and you were human, but you didn’t want to test that theory, so you left it alone.
“It’s okay,” You reached out to hold one of his servos in both of your hands, squeezing reassuringly. “I can feel the sentiment. Just focus on getting better, okay? We have all the time in the world.”
“Sometimes I fear we don’t- Have all the time, I mean, and I suppose that’s why I finally broke down and did this- I like to believe I’m impervious to everything around me, but I’ve already died once, and every time I get sick, I always think about what will happen if I go offline without telling everyone around me just how much they mean. I didn’t want to be scared anymore, not when it came to you.”
“I...” You stood and got on top of the berth so you could sit next to Optimus, curling into his side. “Me, too.”
“Will you be here when I wake up?” The Prime asked and wrapped an arm around you. Gentle. Strong. Warm.
“Would you like me to be?” You asked in return with a tilt of your head.
“Yes.”
“Then I’ll be here,” Optimus looked at you, clearly somewhat doubtful, but you only shook your head with a smile. “I promise, I won’t leave you. Just get some rest, okay?”
“...Okay.”
So, you stayed, and when Ratchet walked in the next morning to see you curled up by Optimus’s side on the berth with your (lip/chap)stick smeared on his servos, both of you sleeping peacefully for once, he couldn’t help but think that Optimus getting sick once in a while wasn’t so bad after all.
