There was good reason for Wanda to not be satisfied, and nowhere else to direct her frustration, but that didn't mean Tony was willing to take it. The loose relaxation he had forced into his shoulders was forgotten for them to tense defensively, and he frowned while she ranted at him like he was supposed to have kept a fucking collar on the kid and taught him how to be a stable, functioning adult himself, or like he had completely missed his own argument when she was the one who couldn't stand to take three seconds to think it through before lashing out. If she didn't like it, maybe she could have made an effort some time in the last year to track her own fucking brother down instead of waiting for Tony to clean up their mess again. He had his own fucking mess, and she was really good at giving him all the space he needed to wade through that by himself, too.
He really, really didn't need her to help him feel guilty.
When she was quite done, expertly playing her powerless, submissive role as a direct follow-up to her classic indignant ignorance, Tony rolled his eyes up to the milky white winter sky and squinted up into its brightness while he considered the small words she obviously wanted him to use. Fuck that, though. He wasn't going back to Hello, World after all this time because Wanda wanted to be babied. They had progressed to far more advanced interaction since the days he had to routinely send her to her room to think about the latest stunt she pulled.
"Okay, so assuming he's not hazardously codependent, had any leadership qualities whatsoever, and had all kinds of well-meaning, like-minded friends I never got to meet, why do you think he completely cut ties with you, made enemies of the Avengers, and went to Genosha?" he eventually presented, laying out her little fantasy world for her to frolic in like the marked and misunderstood princess she obviously so badly wanted to be.
