Well, Richard Mulligan, ever the trouper, was really sick by this time and he had to finish the series... A series finale is not an easy thing to do , but they managed to pull it off with their "feel good" philosophy...
Yes, we know the actress who plays Libby here was on the first season NOT playing Libby, but who cares?? it is a touching scene when she shows up!!!
