Okay, Tony got it. He wasn't supposed to be here and that apology wasn't for him and whatever he had to say on the subject wasn't welcome. She could have asked him to leave before turning the engine on instead of making him sit there while pointedly cutting him out. Then making him sit there while Steve explained what a team was as if Tony needed to hear it again; no, really, he got it loud and clear three days ago when he saw the ruins of the Tower and pulled the bullets out of Steve that should have been avoided. Tony completely understood.
He looked up at Wanda again when she snorted at Steve like she didn't understand at all. And what Tony was hearing was, it was entirely okay for Wanda (and Barton, who had no stake in that family tragedy but had the presence of mind to set explosives in a house Tony thoroughly doubted did not contain casualties) to commit acts of violence because she, alone (which was her version of 'be a team' and clearly always had because none of this was surprising), would handle the fallout that was inevitable either way, despite all of them being at their weakest, despite it being an act of war on the only country functioning without a debilitating plague just waiting for an excuse to wipe the rest of them out. Which she also recognized, because otherwise she had entirely given up, because she had seen people die. Well that was simple fucking math. The only detail Tony was missing was why the fuck Wanda had to include the rest of them in her desperate suicide. He didn't understand that if she was going to sabotage herself by deciding it was the end and deciding to be selfish and deciding that she didn't have the strength to save the day, she couldn't do it without making everything so much fucking worse.
Tony wasn't done. He had enough reason to believe he could save this entire planet staring up at him with big, sleepy, brown eyes. He could do it without the Avengers just like he could do it without the Tower; he didn't need Wanda to believe in anything except Pietro. He wasn't angry at her for any of that. But, okay, that apology wasn't for him. Carefully, Tony eased himself off of the bed, hand on Steve's shoulder in farewell before quietly removing himself from the crowded cell with Anthony in his arms, refusing to look back as he slipped into the privacy of his own room.
