The authors conceptualize Davies's account of the difficult session with her patient Karen as a mentalization mismatch: an expectable failure on the analyst's part to understand the mental state of the patient. In response, the patient used projective identification to re-create the link to the analyst that was temporarily severed. They argue that the therapeutic impasse produced by Karen's successful externalization of a persecuting part of her self is more than repetition of a past relationship. It is the current experience of a disorganized self: a pervasive state for the borderline patient, and a temporary but no less disorganized state in the analyst.
