Yes Jill and Kay were kept apart for some time, which was no bad thing.
It made them coming back into each other's orbits all the more interesting.
Unlike later years where inane stories were created just to keep Victor and Jack's rivalry in the forefront.
After all that Derek and Jill went through they didn't get a farewell scene? I guess the fact that Brenda was gone contributed to that. And whatever happened to Derek's salon? That was his dream yet he seemed quite happy to go to work at Chancellor.
Talking about favorites, I think Bill Bell liked Deborah Adair as he used Jill to introduce the Abbotts. From the youtube episode of Bond she seemed fine so who knows why she was dumped.
Back to Peggy, she was raped while involved with Jack. She was at Chris' apartment .Ron had a grudge against Chris and I think he was there to attack Chris but raped Peggy instead.
Did Jonas and Lucas get proper farewells?
