Contrary to popular belief (coughTonycough), Steve is actually pretty good with 21st century technology. The best way to deal with it was to learn it, so he started teaching himself how to use the microwave, and computer sort of. And then the television. And the…the thing underneath the television. And while chronologically speaking he is ninety-one years old, his brain cells still function like a 24-year-old’s and as we all know from personal experience and scientific study, young people adjust to new technology better than older folks, because of neurons in the brain or something. All this to say, Steve had figured out all of those gadgets SHIELD left in his apartment way before he’d started avenging and living in the Tower with the rest of his team. So even if the incident with the tablet and DUM-E was his fault, it wasn’t because he was a war relic. It could have happened to anyone. The buttons are hard to distinguish from each other. And the PS3 doesn’t work anymore because Thor broke it, not because Steve “fixed it wrong.” He doesn’t see Tony reprimanding Thor for not knowing why someone needs four G’s when they’ve already got three (an honest question!) and he’s from a different planet, for Pete’s sake. Steve just needs a little more time to get used to things, and he’ll be good-to-go on any gadget, anywhere. Touch screens, no problem. He’s got this. He may not like it, but he’ll get it, and then, maybe Tony can start working out or something, because last Steve checked he can still beat Tony up like a little kid, huh, funny how that works. Not that he’d ever beat a little kid. Oh, gosh, no, he’s never – no. That would be wrong and against everything he believes in. BUT that aside Tony is as useless physically as he seems to think Steve is with a remote control, and using smartphones isn’t really vital to life, no Clint, it is not. And Steve thinks he can get along fine in the Tower with no supervision, thanks very much. No, he doesn’t count Jarvis as supervision.
He huffs and charges downstairs to the gym.
Tony is still skeptical.
