Ahh, yes that makes sense then, why she reacts that way towards Ziyal, though of course its again somewhat twisted (though most cardassian seem to be) that she faults Ziyal for it.
But wouldn´t she have heart Damars reputation? Though maybe she ignored this as just false gossip, just as Damar ignored lots of things about Dukat. However she did notice his trembling hands and she did stroke Damars cheek gently (as a fake for the Jem Hadar? But then she must have known, what the other ladies do in his quarters.)
