Bill's former girlfriend Louise Marshall (Rita Gam) comes back into his life, apparently with marriage in mind. Thanks to the dire warnings of Cissy's friend Sharon (Sharon Alberoni), a child of divorce, the kids become convinced that Bill (Brian Keith) will send them back to Terre Haute should he wed Louise--and they aren't about to let that happen. This episode was written by Elroy Schwartz), the brother of Gilligan's Island producer-creator Sherwood Schwartz. ~ Hal Erickson, Rovi
