Knots Landing - Season 2 Episode 11 A State of Mind

Jeff Cunningham is mad that Abby is having an affair with a married man (Richard) in front of the kids. Sid hears Karen talking with Jeff, and tells her not to discuss Abby with him. Karen says that Sid is blind to Abby, but he defends her and they argue. Jeff files for custody of the kids. He and Abby talk, and he admits he wants her back. Abby sleeps with him so he'll drop the case, and then tells him that it was a one-time thing. Jeff is angry and says she's not playing 'fair' with him. One of Laura's clients kisses her, but she says she can't cheat on Richard. Abby tells Richard that it's over between them.
