In an earlier scene, Mitchell bumps his daughters head on a doorframe, but then begins to worry that he may not be ready to have a child. Mitch sees how much Lily likes Cam and how good of a caretaker he is and begins to worry that he is a worse parent, but Cam reassures him that they are both great parents because they complement each other. Their decision to specialize in particular tasks allows them to complete more work together and both recognize they wouldn’t accomplish nearly as much if each had to go it alone.
