The season's long storyline of Greene's illness and death and how it affects many characters marked season eight as the first major turning point in the series.
This season would also mark a major change in the cast with four characters leaving which included original characters Greene and Peter Benton.
For the first time, Carter is centered as the main character of the show at the end of the season and took over as the central character in Season 9 midway through the series, which was a big move in the direction of the show.
