Chris Claremont's finale on EXCALIBUR is a lackluster three-parter titled "Girls' School From HECK" in which Courtney Ross (who Claremont may or may not remember is actually Sat-Yr-9 posing as Courtney) sends Kitty to the finishing school she (Courtney, not Sat-Yr-9 -- but who knows at this point?) attended as a teen.Kitty makes a rival in Phoebe Huntsman, but the girls put aside their differences to become cheerleaders for England's first American football team and save the school from going bankrupt. Yes, you read that right -- Chris Claremont's graceful exit from EXCALIBUR was apparently re-tooled from a teen farce movie script he couldn't sell back in the eighties.
(To be fair, he may have intended the story to come across as an homage to those types of films, but it's played so straight that it doesn't really come across that way.)
