Kind of on the edge of my seat.
I am too. I imagine there is more to Suspiria's plan than to be a sacrifice as she couldn't have known he would confess. It does undermine the whole Conclave if they were using those projection gems to broadcast it, but again there wasn't any reason to know Qtilda would have confessed so easily.
So I'm curious. I admit as well I hold out hope of Blood Mary. Why? Because in any work of fiction whether a TV show or book or otherwise, there are certain chars which catch the audience's attention far more than expected. It's why you see certain chars intended only for a single episode or arc take off and become major parts of a show's story. The same happens in comics and elsewhere. Sort of pre-web virality. When an author stumbles onto a char that resonates like that, it's worth expanding on it because it isn't so common. So cross fingers in that regard.
That of course is a whole separate issue from what Suspiria's plan is and what's happened to her. Perhaps she's simply learned to co-opt those tiny little machines to hold her essence until she decides to return her body now that she's a magical savant? The body itself was a construct to fool Qtilda? I don't know. I suppose she could be dead, but that would indeed seem a bit bleh, particularly as ties back to Crest too. Look forward to seeing how it all plays out though.
