I’m still trying to figure out what Natasha actually MEANT in “Cap3: Civil War” when she exclaimed to Tony “you can’t let go of your damned EGO for one second, can you?”

I mean -- what??? I didn’t see much evidence throughout CACW of Tony flexing his ego -- far from it; almost completely the opposite.  He was consciously deferential to Ross when he was bargaining for more time TO SAVE HIS FRIENDS from Ross’s kill squads. He practically PLEADED with Steve, time and time again, to see reason and sign the Accords.  He did the ONLY thing he could think of doing, before going to meet Steve and the rebels at the airport, to SAVE Steve and the rebels if they got feisty: he brought Peter Parker to “web ‘em up,” which is pretty much the ONLY way you can subdue a super-powered individual without hurting them.

So that line from Nat has always puzzled and frustrated me -- she knows Tony very well. She knows he’s in pain over Rhodey at that moment. So what in holy hell did she mean by that??  Is it just bad screenwriting?  What ego did Tony ever show in CACW?? If it’s just supporting the Accords -- well, Nat did too, and so did the wise Vision and Rhodey, so...
