Master Of None Episode 1.05 The Other Man

Dev's friend Denise invites him to a work party, where he meets her publication's food critic. Right before they have sex, he discovers she is married and backs out. He discusses this further with Denise and a fellow actor from The Sickening, Benjamin, who agree that as long as she doesn't have kids and the husband doesn't find out about it, it's all right. He is still on the fence, but one day the husband cuts in front of him at an ice-cream store. He decides to have the affair and the husband finds out. Weeks later Dev and Denise run into them and learn that the affair brought up several problems the couple faced, and Dev sleeping with the wife actually saved their marriage.
