Maybe it would have been better if he'd pushed her away, ignored her, walked away. What he said actually felt like a slap in the face and she took a step back, wondering if she really heard what she thought she heard in his voice. Maybe she was imagining it, maybe he really didn't care, but why the hell did it sound so accusing? Like she didn't care about the Avengers or like she didn't care about him. One of her main priorities was standing right here in front of her, condemning her.
"If it were you in that cell, Tony, I would've done exactly the same thing," she said quietly, crossing her arms tighter. "Any of you. Pietro's my brother, you're my family. I don't care-" that couldn't have been true, either, "What you think about it but him, you, this weird family, the people I care about, will always come first if their lives are on the line. Always."
Wanda had admitted to being selfish and she couldn't believe for a moment that he wasn't, too. She thought of the silly old 'what if' she'd been hearing all their life- if there was a fire, who would you save first? She didn't doubt for a moment that if he had to choose between say, Steve or Pepper and a roomful of strangers, he'd go for the people he loved first. Or maybe he wouldn't, maybe he was Tony Stark and he just made up his own damn solution to fix every problem but everyone else wasn't Tony Stark.
"I'm not perfect, Tony, I'm no saint. I never said I was. I'm sorry for letting you down," she finished, a little sullen, losing some of her confidence, and told herself not to get upset over disappointing him. What else was new? She was always disappointing him. It shouldn't have actually hurt so much anymore.
