The Series Finale

The episode is about Louise having the group do a creative visualization exercise, trying to figure out why none of the group members have had successful relationships. After everybody winds up depressed after the exercise, Louise has them all think of something that lifts their spirits. Louise visualizes the group members attacking her with kitchen utensils like strainers and whisks, and the episode ends there. Since this was one of a few episodes from the last season that NBC never aired, there wasn't really a "final" episode where John remarried or anything like that. If you happen to have the Antenna TV channel, they air the show overnight, and the final episode will air early next Wednesday morning at 4:30AM Eastern time.

However, if you don't have that channel, the episode is available on YouTube. The episode is called "The Nightmare Continues". Hope this helps.
