Re: Avengers +/-
Cap, as an explanation, Wanda "created" two children for her and her husband. They weren't real, not exactly, and when she was reminded of losing them, that's when she broke. Her brother Pietro convinced her that the Avengers and X-Men were going to kill her for being too unstable, and helped create the mutant superiority reality. This version of her hasn't done it yet. But she does have the ability to. Her powers are intense.
