I would be genuinely delighted to.
Avengers Mansion becomes a thing within two months of everyone housed up (save Thor who is back in Asgard for the time being with Loki business). They all pick rooms and settle in. Tony stops by and asks about what they want to make it their space.
Nat doesn’t have much in the way of requests but what she does ask for comes without delay. Bookcases show up all a rich cherry wood that smells sweet. Not to mention Tony might make her a walk in closet. He doesn’t ask her so much as just goes ahead with it. Nat isn’t even mad because she can recognize this is Tony trying to do something nice for her. Tony who is leaning over for stretches of time and putting too might weight on his bad knee. So Nat just helps and might enlist the others to do the same. It becomes a bonding exercise from there.
And that’s how everyone’s personal modifications go. They do it as a group, themselves. Sometimes with Steve balancing a do-it-yourself books while Clint and Nat glower at him with plaster stuck in their hair. Sure some things are frustrating and they argue. Occasionally they even need to walk away from one another, the first official house rule (1. Don’t escalate, separate. Let cooler heads prevail.) But they put down tiles, take down some walls, and even put up wallpaper together. There are paint fights and the occasional playful scuffle but the job does get done.
Meals after projects are normal. Which makes team meals more common than some might expect. It’s not that they all can sit down together regularly, but that they will make plans. Even if the plans are no more complex than putting in a call for take-out and eating it together. They’re slowly becoming more and more of a team than people brought together through circumstances.
There are side-effects to being together so much. They learn about one another, become friends. And it’s how the Avengers come to understand they all have one thing in common - the compulsion to protect Tony Stark.
Tony who isn’t actually an Avenger but might as well be. Who lives with them, looks after them, and looks up to them. It’s a confounding feeling having a like Stark trust you that much. Tony who will take their word for things and talk them down from any bout of self-loathing he encounters. Stark who turns out to be a softie.
Tony who they realize one day is vulnerable and not an acceptable loss.
It’s no that even merits the full fury of the Avengers. But he has a gun and makes the sensible deduction to point it at the man without the body armor - Tony. Tony who had been there for a team lunch, cane resting against the table. Tony who doesn’t do anything but frown and try to talk the idiot out of what he’s threatening to do.
“Kid don’t do this…” But that’s as much as he says before a chair rams into the thug’s stomach thanks to a sharp, precise kick from Hawkeye.
It’s over quickly, no casualties. Nothing but apparently enough stress on Tony’s heart to make him pass out. The drive to the hospital with like a strategic military rescue between them all. Bruce who keeps watch on Tony, checking his pulse. Nat who drives and Clint who is giving her directions based on the GPS and traffic flow. Then Steve who holds Tony steady for Bruce.
Tony stays for a night of observation with a room full of superheroes apologizing to them for the inconvenience. No one is angry. Instead they sneak food in and spend the night with Tony squeezed into chairs to not leave him alone. But when Tony nods off from the fatigue of the strain of it all, they all come to an agreement. They will protect Tony.
Steve and Bruce take a better control of Tony’s eating, drinking, and sleeping habits. Tony’s alcohol consumption is at an all time low within four months. Tony eats fairly regular healthy meals without issue. Coffee intake doesn’t lower but it happens less frequently at inappropriate hours. Nat and Clint help Tony get exercise. They make a game of it most of the time, inducting Tony into elaborate games of mock-spy hide and seek. The nerd guns are a nice touch and it is fun. They also make certain that Tony’s not overdoing it, the best eyes to spot muscle strain. Making Tony take a break form work is more difficult, but Clint has the idea of a movie night that means they all take a break every week. They come up with a turn system for who picks what movie.
And life if good. They all have a home and friends. But they do try not to forget the only reason that ended up like this was Tony’s pulling them together. It’s about then that Steve slips and calls them a family - no one argues with him.
But Tony starts with withdraw from them all and it only gets worse. The man they’ve all gotten to know for years now is changing back into someone who wore Tony’s face like a mask. The drinking picks up against and Tony shuts himself up in the lab for too long. But when Tony stops showing up to movie night they stop giving him space.
Everyone is gutted when Tony finally cracks and confesses he’s dying. The reactor is killing him, rather. The core is made of palladium and he’s suffering from heavy metal toxicity. He could treat the symptoms and has been for awhile in secret, but he can’t remove the reactor. Tony also confesses he has been trying to find an acceptable replacement for palladium, there is none known to man.
Steve still grips Tony’s shoulder and tells him “We’re in this together Avenger.”
And Tony can’t seem to resist that fully. Even if he tries to be an ass to make them angry, to push them away. They don’t take his shit. Pepper and Rhodey are informed soon after they find out. Even Fury turns up because he’s known Tony since that kid was born and this isn’t under his radar. It’s more than a little overwhelming to Tony that he has people who care about him enough to ignore every attempt he makes to die alone happen.
Time is not on their side because the symptoms of the poisoning only worsen. Tony loses weight, lacks any real appetite so they will feed him anything he wants if it means he eats. His cheeks become more pronounced as he loses weight and the softer spots on Tony that made him seem healthier are gone. His hair dulls slowly and only ever has much sheen to it when it’s greasy. Tony tires so much faster than he used to and they let him rest, guard him when he naps because Tony needs the rest.
They talk among themselves and realize they are almost genuinely out of options. Lawyers had come that morning so Tony can solidify his will. Tony had been cracking jokes about what he’s leaving them for their last movie night. They try to keep some normality for Tony, for them too. Steve remembers resting his hand on Tony’s ankle and wishing he could anchor Tony in their world.
Thor can offer nothing that does not come at a price. The team is so ready to agree to most things at this point but Tony flat out refuses to let them. Tony sites the rest of the world as needing them more than it needs him. None of them might agree but Tony is stubborn as a mule, he won’t budge.
Going through the contents of the mansion with Tony is morbid but they agree to it. In the process they find some of Howard’s old things, and some of Steve’s kept away. Steve has mixed feelings about it all. But they do all watch the reels. Some of it is Steve’s old war highlights, others the propaganda they had been pushing in WWII, and lastly is a bit of Howard from the late seventies. Clint teases Tony about his appearance as a child. Nat is of the same mind. Bruce offers that he thinks Tony was adorable. Tony flings old rubber bands at them for their trouble. Steve is sitting closest to him and spots the mix of emotions that come with seeing Howard.
The away moment that Howard has surprises them all. Steve doesn’t mention anything when he spots hints of tears to his eyes. But somehow seeing a ghost tell Tony he can finish what Howard started gives a little will to Tony to try again. Steve plans to stick with him now, not able to leave him really.
The workshop is quiet, it’s nothing new. Tony hasn’t bothered to play much music in the last month in general. Steve almost misses the sound of AC/DC.
Over the scratching of his sketching Steve hears Tony start mumbling. It’s enough to make him lift his head. As it turns out the display Howard had left behind had been a blueprint, a sort none of them had guessed at. Until Tony had sorted out just what it was, pushing and pulling at the clues until the answer was there in the blue holographic display.
At that moment looking at Tony surrounded by the light, hope and relief in his face, Steve finds himself rising to his feet in a hurry. Striding over while his face breaks out into a grin that matches Tony’s. Steve can’t tell which one of them laughs first, but it’s the best sound he’s heard in ages. Without realizing Steve’s lifted Tony right up off his feet while they laugh. When he settles Tony back onto his feet he is so caught up in the happiness, the relief, the joy, of the moment he kisses Tony.
When they break apart the clarity comes with Tony’s wide-eyed stare. Steve loves Tony. Not the warm camaraderie they all share now. Not even the fondness that had made him hold onto Tony so tightly when he almost lost time to the portal. They are the best of friends. Steve knows more about Tony than he thinks he knows about himself some days. Steve is in love with Tony.
Breaking the news of the rest of the team after that is strange. Steve’s still happy but he’s blindsided by his own affections. Tony seems equally uncertain how to feel. But he smiles and laughs lighter than he has since he confessed to the toxicity. They celebrate of course. They make it an occasion and included a slightly extended list of guests than their usual get togethers.
Over something spiked with Asgardian mead Steve spills to Thor about his revelation. Thor is understandably happy for him. But Steve’s doubts must show because Thor hums thoughtfully. In the end Steve decides no matter what now is not the time for this. Tony is alive and well and they’re all thrilled. Tony needs time to recover and settle again no matter what. No amount of affection Steve feels will allow him to compromise that so he refrains from having the talk he should have with Tony.
Meanwhile Tony maybe tells Rhodey and Pepper about the kiss Steve gave him. Rhodey might choke on his beer. But Pepper eyes Tony and mentions that clearly Tony’s interested if it even got this far. But then Tony shakes his head and reminds her Steve is out of his league. Rhodey calls his bluff but Tony’s still ridiculously stubborn even if he’s worlds better about himself than he once was.
There is a giddiness about Tony’s survival to be sure, but the odd open-ended feel to the conclusion of it all is disconcerting.
So of course that’s when Aldrich Killian comes to SI with business propositions and a hell of a chip on his shoulder concerning Tony Stark. But it’s also thankfully when Janet Van Dyne and Carol Danvers fall into their lives as Avengers. Not to mention the mission Nat and Steve gets to a nation in Africa called Wakanda due to unrest in the area which seems like a power struggle. Sam Wilson is a new recruit from SHIELD who ends up another of their mission party that turns out to be a hell of a lot more impressive in person than in his briefing packet.
