Was it ever explained what happened to Remo & Jeanie in season 4? I know the actors were cut (likely due to Jonathan Winters' big salary), but I don't recall that it was ever explained what happened to the characters.

It seems weird they weren't at Mork & Mindy's wedding, as they were close friends and hung out a lot.

I know that Glenda and Nelson were also written out, but that didn't bother me as much for some reason.
