The new Harvey journeys with new characters
As Harvey tries to unravel his issues, he would turn, mostly to Dr. Agard, his shrink. Korsh said he will visit her more often throughout the season because they wanted to stylize his anxiety. When Harvey said he wanted to examine himself, it cannot just be covered in one episode alone.
Whether his sessions with Dr. Agard develops into a more meaningful relationship, Korsh did not say. But, he said that they looked at a wide variety of actresses and ages for the role and Christina Cole is the best fit. She has American and a British accent. She actually tried for the Rachel Zane role. They thought she was not fit for that character, but she is perfect as Dr. Agard.
Because Harvey and Dr. Agard seemed to be peers of the same age range, this gives the duo a certain dynamism and chemistry. That being said, it is still uncertain if Harvey would already be ready to face another relationship, but Korsh said he probably isn’t.
Lastly, Korsh said there could be a rift in the relationship between Donna and Louis in Season 5. He said that they will hit a fragile point and this can mess things up in the law firm.
