Yeah, her turning into a complete murderous maniac was unexpected. Like the Darkhold obviously corrupted her, but, it was narrated as if she was supposed to just genuinely believe in what she was doing -- getting her kids.
Would have been a lot more believable, for me at least, if she was trying to *save* her children from horrible deaths, instead of simply killing her alternwte self to abduct them. Like show her getting terrible visions of Gargantos swallowing the kids. But then have the reveal be that he created the visions.
Also. Where were Vision and Pietro??????
