The author discusses supervision, transference and countertransference as seen in the context of the clinical case of a patient who had been first seen as a training analysis case and who later, in a fortuitous way, was treated by the supervisor of the training analysis. The supervisor, who in the first instance did not recognize the patient, discusses the reasons for this unusual experience in terms of the presence and absence of transference during the analysis of this patient as a training case and the problems inherent in the task of supervising. The patient's feelings towards the first and the second analyst and the vicissitudes of transference and countertransference during the supervision of the training analysis and its influence on the presentation of the analytical sessions by the student are also detailed and discussed. The question of recorded supervision presentations and their possible influence on the dynamics of supervision is raised.
