Karen Cellini was introduced in a scene where Amanda is being rescued from "La Mirage" hotel fire by her father's former driver (in the seventh season premiere).
According to the movie, Richard Shapiro wrote every word of every dialogue of every episode of "Dynasty" working day and night on his typewriter.

Now Al Corley is back and Steven reverts to his previous face he had lost in the oil rig explosion with no explanation whatsoever.
