Cornelia Frances was type actress that could make any character she played are strong character and always put her heart and soul into it.
But unfortunately I can understand why she didn’t last long on H&A as regular as direction they were taking show in she wasn’t type character that would fit in that era of H&A and why would like to see Morag and Bobby have bit development but unfortunately writers seemed to want keep them hating each other and was starting get bit old them throwing insults at each other.
I could see Morag being one to put Lois in her place had Morag somehow still be on show til 1991.
But I think H&A did well keeping 5 original characters for first ten years though Pippa being recast.
Irene and Sam and Marilyn all being around 5 years or more mark by 1998.
