Susan, meanwhile, was writing about Elliot and Nancy’s troubled marriage and their decision to go into therapy while Marshall and Susan were in therapy. Marshall thought Susan’s depiction of… er… Elliot was a bit harsh but was reluctant to say so, so he deputized me to give his wife notes. Susan knew full well that I was giving her Marshall’s notes and confronted Marshall about it in therapy. A fictionalized version of their confrontation in therapy emerged as a wonderful scene written by Susan, directed by Marshall, and starring Marshall as the therapist.
