<P> In the ninth and final season, the series aired on NBC's Saturday night lineup at 8: 00 p.m. NBC still had confidence in the series, making it the 8: 00 p.m. anchor, kicking off the network's second - highest rated night (next to Thursdays). For February sweeps, the writers created a controversial storyline in this season for the episode titled "The First Time", in which Natalie became the first of the girls to lose her virginity . Lisa Whelchel refused this particular storyline that would have made her character, not Natalie, the first among the four young women in the show to lose her virginity . Having become a Christian when she was 10, Whelchel refused because of her Christian convictions . Whelchel appeared in every episode, but asked to be written out of "The First Time". The episode ran a parental advisory before starting, and placed 22nd in the ratings for the week . </P> <P> With the show still comfortably winning its timeslot, NBC made plans to renew The Facts of Life for a tenth season, but two castmates--Mindy Cohn and Nancy McKeon--chose to leave at the conclusion of season nine . </P> <Table> <Tr> <Th> Actor </Th> <Th> Character </Th> <Th_colspan="12"> Seasons </Th> </Tr> <Tr> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> 5 </Th> <Th> 6 </Th> <Th> 7 </Th> <Th> 8 </Th> <Th> 9 </Th> </Tr> <Tr> <Td> Charlotte Rae </Td> <Td> Edna Garrett </Td> <Td_colspan="7"> Main </Td> <Td_colspan="2"> Absent </Td> </Tr> <Tr> <Td> Lisa Whelchel </Td> <Td> Blair Warner </Td> <Td_colspan="9"> Main </Td> </Tr> <Tr> <Td> Kim Fields </Td> <Td> Tootie Ramsey </Td> <Td_colspan="9"> Main </Td> </Tr> <Tr> <Td> Mindy Cohn </Td> <Td> Natalie Green </Td> <Td_colspan="9"> Main </Td> </Tr> <Tr> <Td> Nancy McKeon </Td> <Td> Jo Polniaczek </Td> <Td_colspan="1"> Absent </Td> <Td_colspan="8"> Main </Td> </Tr> <Tr> <Td> John Lawlor </Td> <Td> Steven Bradley </Td> <Td_colspan="1"> Main </Td> <Td_colspan="8"> Absent </Td> </Tr> <Tr> <Td> Jenny O'Hara </Td> <Td> Emily Mahoney </Td> <Td_colspan="1"> Main </Td> <Td_colspan="8"> Absent </Td> </Tr> <Tr> <Td> Felice Schachter </Td> <Td> Nancy Olsen </Td> <Td_colspan="1"> Main </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="4"> Absent </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="1"> Absent </Td> </Tr> <Tr> <Td> Julie Piekarski </Td> <Td> Sue Ann Weaver </Td> <Td_colspan="1"> Main </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="4"> Absent </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="1"> Absent </Td> </Tr> <Tr> <Td> Julie Anne Haddock </Td> <Td> Cindy Webster </Td> <Td_colspan="1"> Main </Td> <Td_colspan="2"> Recurring </Td> <Td_colspan="4"> Absent </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="1"> Absent </Td> </Tr> <Tr> <Td> Molly Ringwald </Td> <Td> Molly Parker </Td> <Td_colspan="1"> Main </Td> <Td_colspan="1"> Guest </Td> <Td_colspan="7"> Absent </Td> </Tr> <Tr> <Td> Pamela Segall </Td> <Td> Kelly Affinado </Td> <Td_colspan="4"> Absent </Td> <Td_colspan="1"> Main </Td> <Td_colspan="4"> Absent </Td> </Tr> <Tr> <Td> Mackenzie Astin </Td> <Td> Andy Moffett </Td> <Td_colspan="5"> Absent </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="3"> Main </Td> </Tr> <Tr> <Td> George Clooney </Td> <Td> George Burnett </Td> <Td_colspan="6"> Absent </Td> <Td_colspan="1"> Main </Td> <Td_colspan="1"> Recurring </Td> <Td_colspan="1"> Absent </Td> </Tr> <Tr> <Td> Cloris Leachman </Td> <Td> Beverly Ann Stickle </Td> <Td_colspan="7"> Absent </Td> <Td_colspan="2"> Main </Td> </Tr> <Tr> <Td> Sherrie Krenn </Td> <Td> Pippa McKenna </Td> <Td_colspan="8"> Absent </Td> <Td_colspan="1"> Main </Td> </Tr> </Table> <Tr> <Th> Actor </Th> <Th> Character </Th> <Th_colspan="12"> Seasons </Th> </Tr>
