In keeping with Grey’s Anatomy‘s cloying tweeness, the actors on the medical soap are “invited back” for each new season. Or, in Isaiah Washington’s case, not. Washington’s rep recently confirmed the news that the show’s exec producer Shonda Rhimes had not invited his client back for the next season. So we suppose there was no need for Washington to RSVP. An anonymous insider said that the troublemaking Washington had shown a “pattern of problematic behavior” even before the F-word incident with colleague TR Knight. “I imagine [his dismissal] was a result of all that.” Washington’s reaction to his firing, in a statement, was, “I’m mad as hell and I’m not going to take it anymore.” Not original, but predictably menacing just the same.
