Yeah, Zessica's not dead, not so suddenly and not-very-important-ly, plus I doubt Mykage's plans for her are done quite yet. You know how it goes: a character isn't dead unless you
see him or her die/see their dead body.
And about Amata's dream.............the way he was posed when he was......well, on top of Mikono, looked like a wild animal (on all fours), i.e., like how we've seen
Kagura move on all fours. Which makes me wonder if it's Trollkage screwing with
Amata now and putting images of Kagura, looking like Amata, in Amata's head.
But at any rate I think it's safe to say that it's not Amata dreaming that stuff up all on his own. Not exactly in-character for him.
