Somewhere along the line, Tony became Steve's unofficial teacher for all things past and present. Tony, with some help from Jarvis, took to the role quite enthusiastically. First there were the outings. Tony would show up at Steve's SHIELD-gifted apartment at random times and drag him off to a museum or back to Stark Tower because there were things that Steve "absolutely had to see and what was SHIELD doing anyway? Giving him pamphlets?"

The first place Tony took him was the Metropolitan Museum of Art. Tony was bored out of his mind, but it was worth it to see Steve's face light up at each new piece. He remembered his father saying that Steve had been something of an artist himself, so after that day, he arranged for a shipment of every conceivable art supply to be sent to Steve. He thought he'd done a fairly decent job of covering his tracks, but Steve figured out where the gift had come from anyway.

Telling Steve about the many wars America had been in over the years was a little more difficult for him, especially because it forced him to reflect on the role Stark Industries had played in the conflicts. Tony knew he had a lot of blood on his hands, so much that he wasn't sure it could ever be completely washed away. Surprisingly, Steve didn't seem to care about that.

Teaching the good Captain about music was probably Tony's favorite part of the job. He asked Jarvis to compile a list of songs from every decade since Steve's plunge into the ice and put it on the tablet he had given him. He found that Steve's tastes in music were far less old-fashioned than he expected. Steve loved classical music, apparently he always had, and jazz, but he also enjoyed a lot of more modern artists including some of Tony's favorites.

(Of course, the desire to introduce him to new tunes didn't stop Tony from requesting that Jarvis play "Star Spangled Man" every time Steve walked into a room, but that was beside the point.)

Tony knew they had an interesting friendship. It was very different to the rest of the relationships in his life. Steve challenged him in a way that had originally irritated him but eventually made him a better man. On the other side, Tony brought Steve out of the past and helped him to really live in the future. They made a good team.

It had taken Tony a lot of time and thought to adjust to working on a team, but at the end of the day he couldn't imagine not being an Avenger. Maybe he was still a genius, billionaire, playboy, philanthropist, but he was also a hero, suit or no suit. And even if Steve had been one of the first people to call that into question, he was also the one who had made Tony believe it was true.

There were still times when he didn't quite see himself as a hero, when he was just a man trying to make up for past mistakes. But Steve was a hero, and if he believed Tony was as well, he couldn't really argue with that.

One thing was for sure though. Neither one of them was half as good without the other. Tony was glad they'd finally figured that out.
