i skimmed the movies when i was making the 2 gifsets, but the only scene tony said "steve" to steve's face is during the lifting hammer during the party scene in aou... but it was just a lot of people talking over each other so :-/
ahhh yes, that sounds about right—i think i even went into AOU and Civil War specifically listening for the way Steve and Tony addressed each other, and I remember coming out mostly disappointed
just, honestly, doesn’t it make your heart ache, that only when in a party setting, lounging around with the people he’s beginning to trust and hidden behind a sea of other voices—only then does Tony feels safe calling Steve by his name, and not by “Cap,” as if they were closer than they actually were :(
