This article explores the transformations that occur in analytic work from methodological, topographical, and dynamic perspectives, with a particular emphasis on the concept of imaginary transition. Through a theoretical exploration and the presentation of clinical material from five cases, the authors show how the process of working-through emerges in treatment as a result of the changes of rhythm, register, images, phenomena of upheaval, and the numerous displacements that are brought about in and through transference. Events are only markers or clues about a transformation that takes place over the long term.
