More from Lindsey Lloyd above, as well as two new actors below, Lewis Davie and Sirena Mesa, who get their feet wet with two NPCs that are party guests during one of the quests. Apologies to Sirena, but Bettany refused to stop stirring the pot.
You may notice similarities between Grenier, Roggstad, and Bettany, such as their marital issues. This is deliberate, which will be made clear when you play the quest.
