Playing in the park with cute little Billie, handsome student Wilson West meets Mary and both get butterflies. Wilson's impeccable charm, doctor-pa and record pass even Eric's paranoid muster, but on Sunday he divulges that Billie is not kid brother but his own son. At the airport to pick up maternal grandpa Charles Jackson, Matt is smitten at first sight on a girl he later traces and learns is deaf Heather Cain. They date, but she flees the party after some youths make fun of her sign-language. Eric and the kids welcome grandpa's new 'significant friend' Ginger, but Annie irrationally rages against any suggestion a successor for her ma could be less then diabolic.
