When Richard returned home, after being institutionalized, there was a glimmer of hope and they tried to rebuild their marriage. But when Laura discovered Richard was still scheming with Abby they both realized they should separate and Richard disappeared. Laura's life improved as she started working for Gary Ewing Enterprises, although she has to work closely with Abby, and she meets and they begin an affair Gregory Sumner.

In 1987, the production of Knots Landing was hit by major budget cuts and many actors were let go, including McCashin. Much controversy surrounded this decision made by the producers and was even objected openly by McCashin herself. McCashin explained to Boston.com in 2009 stating, "I was very hurt the way I was let go for financial reasons. I wish they'd handled my demise better".
