Laura thinks nothing of the fact that the beautiful movie star Valerie Blake is guest starring on Alan Brady's show until Jerry starts kidding to her that not even Rob would be able to resist the advances of such a famous and beautiful woman. When Rob has to work late to rewrite a sketch for Valerie, which they have to rehearse as well, which in turn is followed by another late working night as Alan didn't like the rewrites, Laura starts to get jealous. Her jealousy is heightened even more when she finds Rob's handkerchief stained with lipstick that is not hers. Laura stops speaking to Rob after she confronts him with her suspicions about him and Valerie. Only seeing Rob and Valerie together will fully answer Laura's questions about what is truly going on between the two.
