Floyd and Charley know that Dr. Newton is starting to make Kate nervous. Despite the secretive nature of their lodge, the men offer to hold their upcoming lodge meeting, where Uncle Joe is going through an important initiation process, at the hotel. They hope that this ensures that Kate and the girls feel safe from Dr. Newton. Goings-on during and after the initiation ceremony ultimately settle Kate's mind about Dr. Newton.
