Gary and Valene married for the third time in the 300th episode of Knots Landing (Season 12, Episode 24).
It was during Season 11 when Gary and Val became a live-in couple again for the first time since Val left Gary in the Season 3 cliffhanger after discovering Gary's affair with Abby. For years afterwards, a Gary and Val reunion would be teased, and it would never quite happen. A reunion almost happened early in Season 4 when Gary pleaded "don't give up on us!", again in Season 5 when the twins Bobby and Betsy were conceived but Gary married Abby instead. In Season 7, as Val was marrying Ben, it was obvious that she and Gary were in love yet separate as Gary was married to Abby and Val was about to marry Ben. In Season 9, with Ben gone to South America, Gary and Abby divorced and Gary's new relationship with Jill somewhat on-off, Gary and Val had some one-night stands and it looked like they were drawing close enough to be together again, but Val went ballistic when Gary demanded a paternity test on Bobby and Betsy (as Ben had been their legal father) and it drove them apart again.
Jill tried to kill Val in the Season 9 cliffhanger and make it look like a suicide, Jill was eventually exposed and Val turned the tables as Jill became scared of her instead. Jill accidently killed herself in Season 10 and Ben had disappeared since late Season 8, and it finally looked like Gary and Val had no obstacles left (in Season 10), but then came Danny Waleska who Val fell in lust with and married. Only when Val saw Danny's true colours in Season 11 did she finally reunite properly with Gary and start living together with him again in a relationship (their children Bobby and Betsy too), and they got engaged. After Danny's death in Season 12 though, the scriptwriters (the Lechowicks) couldn't resist throwing another potential spanner in the works and gave Val a "brain virus" where she acted very strange and erratically after bumping her head, calling off the engagement for a time. Gary and Val married again late in Season 12.
