I am sad to see Mohan leave. That actress is lovely. Mel is possibly leaving but not sure if that is a negotiation ploy. Her wacky personality change now that her sister is no longer hanging on her every move might be a fun one. She suddenly goes all hedonist, etc.
I was resisting the importance of the Dr. Robby death wish until the last two episodes and they handled it pretty well with his friend and with dr. Abbott talking him through it as men. Sort or ties to first season of True Detective where two men who fought like brothers eventually have a moment of spartan truth.
