This paper discusses clinical cases presented by Comins and Eliot within a paradigm of psychoanalytic supervisory work based on relational theory. Here, in making the medium of supervision more symmetrical with the message of contemporary psychoanalytic ideas about structure of mind health, pathology, and treatment, the relationship between the supervisor and supervisee is considered to contain crucial supervisory data to be delineated and discussed by both members of the dyad. The supervisory relationship is described using three dimensions: power and authority, the data held to be relevant for supervisory conversations, and the mode of the supervisor's participation in the supervisory process.
