So the point of this exercise, as Tony liked to put it, wasn’t to show up the two Really Old Guys and make them realize that they ought to retire.
Seriously, Tony wasn’t blind and despite all the senior citizen jokes, Steve Rogers and Bucky Barnes were pretty much on the right side of young, fit and smoking hot. He was also familiar with the Three Rules regarding America’s Sweetheart and America’s Oldest Heartthrob and would have to admit that he was solidly set upon Rule No. 3. Which was okay, since everyone else on the planet was crushing on the good captain and his sergeant. Nice to know he wasn’t alone and all that.
The point was that they needed to test the combat fitness and teamwork of Captain America and the newly reclaimed Winter Soldier. Tony, by the way, had JARVIS archive the priceless footage of Steve Rogers planting his feet by the river of truth (quote unquote) and proving, beyond a shadow of a doubt, that James Buchanan Barnes could not be held truly responsible for his actions as HYDRA’s pet assassin. He was the country’s longest held POW, subject to unimaginable torment and brainwashing, and yeah - at the end of it, Tony was fairly sure Steve would’ve been elected President of the United States if he wanted to, the show of support was so overwhelming.
So anyway. Retraining. Getting Cap and Bucky back in the saddle against the Forces of Evil. And also this was a GIANT FUCK YOU to HYDRA and the long dead Obadiah Stane for what they’d forced Barnes to do to Tony’s parents - never mind Daddy Issues.
Tony sets up the ginormous Training Room (“room” was an understatement but it had to do) which he referred to as “The Jungle” because he pretty much had classic G n’ R playing while he designed the place. The Room could be set up to simulate any environment, any structure for a nearly infinite number of potential missions and ops. Happy and Maria Hill brought in the agents - carefully screened and processed to infinity because again, HYDRA - as opponents.
The objective for today was a rescue. Since Tony valued his balls and also hey, trying not to be a sexist pig here, Natasha wasn’t going to be the damsel in distress. Clint got the honors.
"Why do I gotta play Princess Toadstool?" Clint had whined. "I don’t even look good in a pink dress!"
"Because Nat will probably rescue herself in Real Life before the rest of us idiots can even get our acts together," Tony explained patiently. "And I’ll get you a purple dress if it makes you happy. Now go sit tight and wait for Mario and Luigi to come save you."
Naturally, Agent - no, Director Agent brought the popcorn.
