This article suggests that supervision is potentially a multi-dimensional developmental space for both the supervisee and the supervisor. It demonstrates how this occurs through a case study of a personal supervisory experience early in the author’s career. There are examples of multiple transference/counter-transference interactions between patient and clinician, supervisee and supervisor, and supervisor and patient. Attention is paid to the experience of lying in the supervision and in development, in general. The author concludes with a description of an orientation toward supervising that attempts to create a developmental space.
