Chewing on the parallels of Aranessa's breakdown about how she tried to do everything right and proper and be a Lady of her House and it fell down around her anyway, nothing she did "right" mattered, and then Maya's breakdown of doing everything right and proper as a Lady of her House and it fell down around her anyway, nothing she did "right" mattered.
She wants to blame Aranessa for their downfall, as in their lives as noblewomen Maya is fully in that "our role is to continue the bloodline and ensure the future of the House" mindset. Maya did her duty, having two children to carry on for Davinos. She's lashing out about Aranessa not doing that due to Thjazi, but in the end, whether Aranessa had children or not - and until all this, her brother and his line were her heirs - they would still, as Julien points out, be in danger, if not already cursed or dead. As Callowyn and Alba already are.
They did their duty. They did everything right. It didn't matter.
And meanwhile there's young Ingrid, seeing all this, and deciding she may have to do things differently.
