In the episode, it all kicked off when Lloyd, Walker and the other ranch hands were herding the cattle for doctoring.
Although the herd had pink eye, which risked the health of the other animals of the Ranch, Lloyd insisted on taking the animal to the arena to make doctoring easier.
Walker publicly disagreed, suggested they should do it where they were to avoid putting the other animals at risk.
