"You all lived in the Tower together?" Tony asked with just a little bit of awed disbelief at the idea - that would have been amazing. Back at the Academy Steve had lived in one of the other dorms, while Tony had been alone in the tower for a while, at least until Pepper and some of the others had joined up. He wished that was something he could say for his Steve, but they'd gone off to do different things with the closing of the Academy, Steve didn't need to stay with him - he was off with Bucky.
But Tony wasn't here to let himself think about all the things he didn't have, or that Steve was off with his best friend or anything else like that. He was here right now with this Steve and he was offering to teach him a little bit and Tony would have to be an idiot to not take him up on that - and Tony was not an idiot.
"Yeah," He nodded, all eager and excited, enough that GERTY picked up on it looking excited and ready to cheer him on, it was one thing he'd noticed fairly early on about his new little pet, the way she seemed always so eager to cheer him on no matter what he was doing. "Yeah that'd be really cool."
