 "The Chase" continued an ongoing storyline of Katherine Mayfair exploring her sexuality. The pairing of Katherine and Robin marks the first lesbian relationship in Desperate Housewives. Actress Dana Delany praised the subplot. She said she did not know if the character would become a lesbian permanently, because the story lines change so often in Desperate Housewives, but that series creator Marc Cherry "is interested in playing the complexity of that". Delany compared Katherine's new realizations to that of actress Meredith Baxter, who realized she was a lesbian late in her life after entering into a relationship with a woman. Delany said she believed her character would be taken by surprise by the new feelings she is experiencing: "I think that she ’ s still so emotionally vulnerable from getting out of the loony bin, and I think she and Robin connect on a kind of wounded, emotional level. And I think if anything, she ’ s feeling this kind of emotional solace with her, and that draws her to Robin in a physical way, and that ’ s confusing to her."
