Casey is sick of having no room in the Venturi house and brings up the subject to Derek and the rest of their siblings. Derek, who doesn't like sharing or losing, tells Casey how they get things in his house. After handing out marbles to represent the disputed areas in the house they start challenging one another for the other marbles. Neither side plays fair, and both sides will be underestimated.
