Rob and Laura are having a romantic dinner at a restaurant before heading out for a night at the theater. They invited Jerry and Millie to tag along, but the Helpers declined as Millie said that Jerry had an issue he had to deal with at the office. That's why Laura is surprised to see Jerry at the restaurant, and even more surprised that he is having what looks to be a romantic rendezvous himself with someone - a beautiful blonde - who is obviously not Millie. Jerry doesn't see them and they try to hide themselves from Jerry's view during the course of their respective dinners. While Laura believes the worst, Rob wants to give his friend the benefit of the doubt. Laura's beliefs are strengthened by implications directly from Millie, and by a similar sighting of Jerry with an unknown woman by Sally. Rob's conversation with Jerry about the issue brings the full story to light.
