There is a bug going around Julia and Giron talking to Pater and forcing him to accept new law from King. I had to see that conversation twice in same game.If Giron leaves his office at noon, you haven't heard him talk to the Pater about polygamy. Once you have heard the conversation in the church Giron stops leaving his office at noon.
Once when King came and left and you get to hear the dialogues between Giron and Pater. But when Julia proposal of marriage or Emily Marriage is done that dialogue must happen again to make the quest move forward. I think it's cross quest bug where a safety check is perhaps disabling the first conversation by mistake.
