I really agree with Goremgyrl. Olivia made Nicole real, and complex. She was a monster and vulnerable, created atipathy and sympathy at the same time, and just when you thought you had her pegged, she saved someone's life! She and "Bobby" had a chemistry that brought life into each show, and it is a shame to feel that she is permanently out. Of course, no one in a T.V. series can be counted as permanently "out", just look at all the "dead" people who astonishingly re-appear. The fact that her character has (apparently) died bothers me, as though she were a real person, which says something to her ability to fill a role and make it her own.
