Knots Landing - Season 7 Episode 18

Peter tells Greg that he's his brother, and brings Sylvia to meet him. Laura thinks Peter is up to something, and is frustrated that Greg seems unconcerned. Abby overhears Laura telling this to Karen, and she asks Peter out for a drink. Gary decides to go into racing. Karen finds Jill's hotel key in Mac's pocket and confronts him with it. He tries to explain that he would never use it, but it made him feel younger, more alive, like life wasn't passing him by, and he hopes Karen will understand. Crying, she says no. Mac's upset that Jill went through his Westfall file without permission. Sonny accidentally drops a tape marked ""Cathy #3"". Val plays the tape, and hears Sonny's notes about his articles. Meanwhile, Sonny is out to dinner with Cathy. She tells him how Joshua tried to throw her off of the roof, and that Lilimae saved her life. Sonny says he's sorry for what Joshua did to her.
