[@OppositionJ] Ziotea might have been willing to go, if only to see a demon in person.  She's a capable fighter, and not bad at controlling a battlefield -- she could probably knock Tatiana or the demon away if things got bad.  No idea if she's the sort Tatiana would want to have on that sort of thing -- probably not, actually -- but she would have been quietly interested, even if she didn't say anything.
