David Schramm essentially left the business after Wings (http://www.aoltv.com/2010/04/19/wings-cast-where-are-they-now/) ended (he only has one credit (https://www.imdb.com/name/nm0775116/) post-Wings). The Fay character seemed to disappear in the final season though Rebecca Schull was still credited. I worried at the time that she might be ill but she's still acting (https://www.imdb.com/name/nm0776042/). The guy who replaced Thomas Haden Church (Brian Haley) was fired and they never mentioned what happened to his character. And weren't there rumors that Crystal Bernard felt threatened when Farrah Forke was added to the cast and lobbied to get her fired?
