Work Text:
Tony Stark has problems. After Infinity war, he just wanna rest. He's so done with all the stress, nightmares, insomnia, alcohol addiction (scratch that, Peter's softness change it into coffee now), severe anxiety, and all the stuff in superhero business.
Retirement might be the words he's seeking. Get married (finally!), enjoying his time with pepper, has kids (like Peter is not his son already), maybe spending little time in lab (or a lot), and keeping tabs on his Spidey intern.
So here lies the core problem. How could he really relax when his son/intern constantly putting himself in danger? How will he maintain his "mind health"?
Tony doesn't know that Peter knows.
Well instead having that heart-to-heart father-son talk, Peter just having the greatest. idea. ever.
It's been two weeks since Peter lock himself up in his lab. He just go out to eat, sleep, go to bathroom, and patrol. Thankfully it's summer. Tony and pepper get frustrated because Peter maintains very high level of secrecy. Even Karen locks his door all the time. That one time at first week Tony saw a box delivered to Peter's lab from the lobby, he can almost peek and just read a word "polymer" before Peter running to it. Tony almost running too following Peter to his lab.
Peter is making something with some kind of polymer that is not available at stark industries. Hmm...
"It's a secret." Peter said, closing the lab doors behind him. He's not going to let Mr Stark in, especially in this critical timing.
"Oh come on, what polymer is that? What project are you doing? Don't make me ask Friday."
"No, you wouldn't. You promised that my lab is my safe place."
"But.."
"You did promise to not having me peek into Peter's room and lab, boss. That areas are Karen's authority." Says Friday.
"Please, Tony, this one project is a surprise. You'll see it when I think you're ready to see it." He said with his puppy eyes.
How could tony say no to this adorable and smart kid?
When the project is done, Peter secretly/unsecretly put the module in the corner of living room. Leaving to pepper and tony to find it themselves.
"So it's done." Tony ask as they having dinner.
"Yep." Peter popping the p.
"Where is it? Show me."
"After dinner, boys." Pepper says.
"Really, show me Pete, all the secrecy is killing me." Tony ask again, clearly shows his persistence. "Is it a weapon for the avengers? A robot? part of ironman suit? A quinjet?"
Peter just laughs.
"Oh come on."
In the event of protests, tony accidently push a plate with his hands. Soon, ceramics shattered in the floor.
Tony's eyes got wide. Images from various fights floods him. The broken glass, shot of guns, bombs, dead bodies lying down, when his armor shattered from every punch from Captain America, but the worst, when Peter turn to dust in his arms. He's back to be iron man who failed to catch his girlfriend from exploding oil rigs.
He's numb, yet panicking.
Tony years his name called several times before he feels something soft touching him in the shoulder. Not Peter's or pepper's hand. Soon after, that thing is hugging him.
Wait, hugging.
And saying in robotic, almost Human voice. "It's okay, you're okay, this is just a small panic attack. You have to breathe with me. In, out, in, out... Good job!"
Once Tony can compose himself, he's totally teared up between proud and confused.
"Hello Tony Stark, I am Baymax, your personal healthcare companion. It appears you just have a panic attack. How are you feeling?"
"Um... Okay?" Baymax helping him stand. The robot is so big, taller than Tony.
Baymax is.. smiling? Isn't Baymax that character in Disney movie? Is this the project Peter was working on?
"Scanning... no physical injury. Be careful we have some broken glass on the floor nearby."
Oh yeah, the plate scatters everywhere.
"Your heart and respiration rate is now normal. On the scale of one to ten, how good are you feeling?"
"I'm fine, really." Tony saw the smirk in Peter's.
"The scale one is, I'm rock ! And the scale ten is, help me I'm having a panic attack. How is your scale?"
"Um, three?"
"I suggest a mild sedation so you can rest. Do you want the treatment?"
"No?"
"How about a hug?"
"What?"
"A hug. The comfort will ease your mind and help you recover. The companion of the loved ones will also help." Baymax gestures at Peter and Pepper.
Peter smiles and takes Tony to the couch. Soon they snuggle up to each other after they clean up the kitchen. Baymax ackwardly stands in the back of the couch.
"So Tony, On the scale of one to ten, how good are you feel now?" Baymax asks.
"One, definitely one."
"Excellent. Are you satisfied with the care?"
"Yeah, thanks Baymax."
The big, goofy robot wave his hand a bit, then go to the corner of the room, then deflate onto his station module.
"That's a great project, pete. I'm so proud." Tony said to peter.
Peter smile widely. "Very hugable, right? tomorrow I'll start coding the 2.0 upgrade."
"Don't you dare."
