Hannelore escaping ditter is, let me check, yup certainly not an option. She'll get dragged into it whether she likes to or not, this is still Dunkelfelger after all.
On Alexandria's ranking I have heavy suspicions a certain scheming Gremlin handler has advised the Zent and the Gremlin to suppress Alexandria's ranking for a while in light of the rather close connection between Aub Alexandria and Zent Eglantine. The country just survived an invasion/coup, keeping the other nobles content is a higher priority than accurately ranking the duchies.
Regarding their next 'actual' rank I still think they would evaluate a bit lower than where Alexandria should be simply because Rozemyne's library strategy will take some time to take effect but once it does they could feasibly reach #1 and stay there. Alexandria as is simply is not focusing on anything that produces immediate tangible "duchy points" so to speak. Education and knowledge are abstract concepts that seemingly don't influence the rankings nearly as much as hard achievements do. Though the latter is just a consequence of the former.
Not that anyone will complain about the Divine Avatar not dominating the rankings, which will just be another behind the scenes factor. Rozemyne very clearly can't be bothered about her duchy's rank and I imagine Ferdinand would like to avoid the hassle that comes with it as well for a good while. Up until some fool mocks his wife or their adoptive daughter for it, then the gloves come off, in the latter case whoever did it better run because they're in for a divine crushing.
