As J.R. continues his single minded pursuit to discover the identity of the spy within Ewing Oil who is providing Barnes with confidential business information, Katherine Wentworth continues her scheming to marry Bobby by getting more information about Jenna Wade's child that everyone assumes is Bobby's daughter.

Meanwhile, Lucy tells Sue Ellen that she feels it's time to quit mourning over the death of Mickey, and that she wants to begin moving on with the rest of her life by asking Peter to escort her to a friends wedding. Despite the fact that Lucy is very aware that Peter has a strong attraction to Sue Ellen, and even appears to be embarrassingly shocked when Peter turns her offer down. Peter later confronts Sue Ellen outside a store front to express his dissatisfaction that she's not doing enough to maintain their mutually agreed upon friendship. In response, Sue Ellen isn't the least bit concerned that Peter's unrelenting need to be with her might be signs of a serious obsessive-compulsive disorder that needs to be treated, and simply tries to convince Peter that she wants to just remain friends.

J.R. eventually discovers that the spy at Ewing Oil is the office secretary Sly, and after confronting her with the evidence, suggest that she work with him to double cross Cliff Barnes.
