As Harvey goes after Forstman in order to help Cahill, we dip into the past to see where Forstman first appeared. We are also introduced to Donna as she appeared the first time she and Harvey made their pact. This is another wonderful effort to show how you can use a person's strengths to draw them out. With Forstman, we find out that he took advantage of Harvey, using Harvey's brother to his advantage. This eventually leads to a basic sting. The other part of the episode involves the previousl episode where Harvey told Donna he loved her. Donna has been waiting forever to get some real love from him. She gets the admiration from Louis. By the way, there is a great bit here involving an unlikable secretary who dies. This is choice.
