   Summary

   "Sothis, the progenitor god, mother of Fódlan and all who reside within it, has blessed us with Byleth to bring renewed life and vitality to the continent, so that her children may protect its peace for many generations to come."

   Oh. Oh. Rodrigue remembered with embarrassment his lurid thoughts about the young lady earlier. "So she imbues those around her with some kind of mating drive."

   "Such vulgar words about the Goddess' vessel border on blasphemy, Duke Fraldarius," the archbishop said in a tone colder than any winter in Sreng. "But you must understand now the urgency of my request. Since she stepped foot out of the monastery, unworthy suitors dog her every step. If you think His Majesty’s actions were extreme, I assure you he is remarkably restrained for someone in his time of life. The blood of the Goddess still runs strong in his veins. It is why he is suited for this honor.”

   ---

   His marriage to Byleth has some unexpected effects on Dimitri. Rodrigue has no choice but to watch.
