1978 (#7) - Katherine's deception and her marriage to Derek

Despite Derek's refusal, Katherine is more determined than ever to make man her own. So, one night, Katherine gets the man drunk and, having arranged a wedding ceremony quickly, manages to marry him under false pretenses. The next day, when Katherine realizes that Derek doesn't remember anything that happened the night before, she ends up revealing to him that he woke up in his bed having made love the night before without any condition; Katherine's plan, after all, is first of all to make the man fall in love and only then to reveal to him about their marriage. Derek can't believe he could have sex with Katherine, so he decides to keep it a secret from Jill. Katherine denies everyone, especially Brock and Jill, that she has put a plan in place to make Derek her own, but he lets out some anxiety when he shows guilt to Jill. Soon, taking advantage of Katherine's lack of clarity, Derek manages to snatch from her the fact that the two got married. As Katherine begins to speak, begging Derek not to ruin it, the man is shocked. Despite Katherine's attempts to make him give up, Derek thus confesses to a horrified Jill the truth. The girl, convinced that the responsibility for what happened is exclusively Katherine's, Jill forgives Derek, but incites him to ask for the annulment of his marriage to Katherine. On hearing the news, Katherine is devastated and seeks suicide, but is saved by the emergency surgery of Derek and Brock, who tried to convince the man not to give her mother a pain with the divorce. Jill is not surprised by Katherine's attempt to take her own life, convinced that it was only a move to get pity from Derek and convince him to stay attached to her; Derek, however, thinks that Katherine's gesture was genuine even if, at Jill's exhortations to end her relationship with Katherine, confirms his willingness to divorce and get back with the girl.
