Perry Stephens left the role in 1990 or 1991, to be replaced by Christopher Cass. I guess Cass wasn't as popular. When Jack was written out in 1992 or so I think the door was left open, but he was presumed dead.
That could be a possibility, but I'm not sure. Minnie was mostly a counsel to Egypt, a schemer who had a secret past marriage to Alex Masters (it was this that led viewers to learn "Clay" was a con, I believe). Minnie stayed with Egypt through the time that the truth came out, Alex fell from grace, went through a recast and eventually got back together with Egypt. She had a big role at the hot spot Curtis Alden and Egypt's brother opened in mid-1989 (a lot of those clips are on YT). I think she was written out around 1990 or so, although she may have popped up again briefly with another actress during Egypt's 1993 or 1994 appearances.
Thanks. I'd never seen those Geyheart clips.
