It turns out the female half of Couple A and the male half of Couple B were both so distraught over the rumors that their mates were cheating on them that they wound up spending a lot of time comforting each other. The comforting became so frequent and so physical that it resulted in a pregnancy. Now Couple A raising a child that is only half theirs. Fortunately for them, the child looks more like the Couple A mother than the Couple B father, but those in the know can definitely see the Couple B father in the facial features. One additional hint: all of the people involved have been actors at some point.
