In a sense, the whole novel revolves around Brett. Since Jacob is basically the only person that Brett is honest with, it gives the reader an insight to the evolution of her relationship and life experiences. Jacob starts to get irritated at Brett's casual confessions to him; his discomfort clearly shows that he does not like being her confidant. After all, his sex life with her is tender. His empathy towards Brett dissolved because he is repulsed that Robert Cohn is her lover. This created more conflict as days passed and Jacob realized that his affair with Brett was over. Everyone liked Brett and enjoyed her company. Jake's relationship with Brett is a treasured path through which we learn more about the characters. His love situation with Brett makes Jacob the ideal person to help the reader to understand Brett and to learn about the other characters. For example, when Brett sent the count away for champagne she opened up to Jake. Do you feel better, darling? Is the head any better? Brett said to Jake as she was nursing him back to health. .It's my fault, Jake. It's the way I'm made. I know you are right. I'm just low, and when I'm low I talk like a fool. Other insights into the novel would never have occurred if Jake did not narrate the story. When Robert Cohn and Frances Clyne see Jake in Paris, Frances takes Jake aside and begins to unload her problems on him. Oh, he told everyone that we were going to be married, and I told my mother and everyone, and now he doesn't want to do it I wouldn't marry him if he doesn't want to. Of course I wouldn't. I wouldn't marry him now for anything. But it does seem to me to be a little late now, after we've waited three years, and I've just gotten my divorce. Jacob also adds a compelling thickness to the plot with his thoughts about Robert Cohn. Cohn is very much in love with Brett, but without Jake he would not have had the gall to stay with the crew as long as he did.
