About "Grip"
Fred's feathers really get ruffled when Grip visits from St. Louis claiming that he is Lamont's actual father. Aunt Esther's normally morally upright image gets deflated when it was revealed that in her youth, young Grip had sneaked into her bedroom, thinking it was Elizabeth -- in the Winfield house and had sex with her! Grip had mistaken Esther for Fred's late wife Elizabeth in the dark, which led Grip to believe that he was Lamont's real father. When Grip realizes this, he recoils -- saying "Me? and her!?" shuddering as he leaves the Sanford residence!
