On the same evening, per the Mayor's request, Mel goes out to dinner with an artist to discuss bringing his installations to Toledo. But when Mel gets a call from a depressed Joe at his reunion, she rushes over there to surprise him by posing as his girlfriend and save the day - only to realize that in the meantime, Joe has found and reconnected with an old flame. And Lennox and Ryder decide to throw a party with Mel and Joe out for the evening, but it does not go as planned.
