Gabby threatens to fire Luis and Jon when they bring their rivalry to work. Jackie and Emily have different ideas about the perfect venue for Luis' party. Ben takes Sophi on a boat tour of the island, while Cat blames her mom for her fight with Ben, further damaging an already tense mother-daughter relationship.
