Lavon's been distracted thanks to his Ruby Debacle, which is why he assigned Zoe and Wade the most important roles in Pioneer Days -- that of BlueBell's Founding Couple -- and THAT is why Zoe is reading Mrs Founding Couple's Diary in bed here. Apparently, this tome is a Belles favorite and full of helpful tips for successful long-term relationships -- or, rather, ONE helpful tip: whenever your partner enrages you, just... don't get mad at them. Turn it into a positive! My personal favorite positive in this scene is Wade's bare chest.
