That she had tried to track Pietro down, had almost gone to Genosha several times, was no matter to Tony because he didn't know and as far as Wanda was concerned he never would. She should have gone after Pietro, but- if what he expressed in his note and letter was true- he didn't want her to. That her father wanted her dead (and that, yes, she was terrified of him) was no small hindrance itself and so Wanda had to content herself with inaction and no real answers. But she wasn't going to try to lie about it to make herself feel better either. That wasn't going to make the situation seem rational.
"I don't know," she answered flatly and the fire blazed in her eyes again. "But unless my father has suddenly turned into a kind and gentle saint, Pietro's going to Genosha won't make sense even if you want it to. Our father is a monster. He hates us. He's tried to kill us. He abused us and he tortured us-" She unconsciously moved her fingers to her lower back where the "M" still scarred her skin. "The things he made us do, his children. We were terrorists for him. We were murderers. I was daddy's little whore. Pietro was his whipping boy. Escaping Genosha was a second chance for both of us. The chance for Pietro to have a normal life and he left Genosha, he took that chance. He knows full well what our father is. So please, tell me, why do you think he abandoned me, left the Avengers, and went back to Magnus?" she shot his own sarcastic question back to him, arms crossed and eyebrows raised. Wanda had never meant for this conversation to happen, but hearing Tony's reasoning made what Pietro had done seem even more bizarre.
In spite of Pietro's assurances that this was what he wanted, she could not understand how he could willingly subject himself to Magnus' cruelty again and so easily forsake his sister in the process. It was the one fact that Wanda could not resign herself to even if she was willing to accept something like Tony's version of events or any of the other scenarios she'd considered in order to help her cope.
