Imagine the Basileus arriving in Szekelyföld with huge retinue and a lot of purple cloth: "''xcuse me, my wife sits in prison here and this is for our son, he needs to be wiped off with these after the birth, or we get succession issues over there in Constantinople".
On a related sidenote, When the Hungarians lately caught my wife tech-spying in their capital (being honest, I had claims on Sopron and Pressburg and wanted to know how much army their current revolt had) the King freed her later after I had won my war against him. My Duke was in love with her, god was he happy:happy:.
