Plot synopsis
Susan Lewis returns to the show providing continuity of the earlier years and some closure with Greene. Weaver also has a revelation and confronts and accepts her sexuality.
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.
Also this season, two new main characters with very different personalities: Michael Gallant and later Greg Pratt were introduced.
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.
