The Avengers are, of course, trying to get him changed back, but they’re also… sort of enthralled with the fact that Tony hasn’t really changed at all? He comes and goes as he pleases, randomly demands attention, and sleeps wherever he wants. (One time he slept on Bucky’s gun. On top of a gun. Tony why.) He also enjoys just sitting between people having a conversation and yelling. He doesn’t want anything, he just… wails.
Natasha has the most pictures of him on her phone, mostly because Tony actually stays still for her. Steve even hears her mumble “stick his leggy out real far” as she takes a picture at one point. He doesn’t know what that means.
