Young Avengers: the Children's Crusade 7 is out. We finally learn the truth behind Wanda's madness in Disassembled. Basically, after losing her children, Wanda went to Doom for help, and together they cast a spell that wound up giving her almost limitless power but driving her crazy.
I'm not sure how I feel about this retcon. On the one hand, Wanda's insanity wasn't the result of an innate character flaw. On the other hand, Wanda was an idiot for going to Doom instead of Strange, Clea, Voodoo, etc.
I wonder when Wanda went to Doom since he was in Hell for several months preceding Disassembled.
At the end of the story, Doom becomes omnipotent and has healed his face. I wonder if this was intended as a tribute to Secret Wars 10.
So... her kids are pieces/fragments of the Beyonder?
No, it's not in there. I'm just guessing/musing at the implications (yes, very reminiscent of Secret Wars).
