This wiki has always followed a simple rule: if a cast member is given "starring credits" (which Isaiah Washington did for s5), regardless of how many episodes they appear (or credited) in, the character is considered a major/main character for the season. This is why Callie Cartwig is listed as a main even though she appeared in a grand total of one episode. Btw, this is stated within this community's editing guides.
