Doug stops by Carrie's office, and is introduced to her work-husband Curt. Although Carrie assures him that he has nothing to worry about since Curt is gay, Doug is threatened by just how close the two are. They go to lunch together, share work secrets, and are very tight. He raises his concerns to Carrie, but she tells him that he has the same relationship with Deacon. Doug is not happy with her comparison, and the two than try to make each other jealous by spending more time with their "work spouses" than with each other. Meanwhile, Arthur is jealous of a new dog that Holly has added to her route.
