Claire and Cam want to flip a house, but Phil and Mitch are against it. Phil pretends he is for it leaving Mitch to put his foot down, but eventually Mitch decides to play the good cop as well and leave Phil to put the brakes on the house. If Phil and Mitch had agreed before hand to both be against the plan (cooperate), they could have come to the best outcome, but it was in Phil’s best interest to deviate and act like he supports Claire and Cam, leave Mitchel to take the full cost of the outcome. Mitchel then decides to defect as well and they are now both supporting a project they don’t believe in. This scene represents a more common version of prisoner’s dilemma in which both Phil and Mitchell would be better off cooperating, but they each have an incentive to defect.
