Drawing on Ferenczi's “confusion of tongues” paradigm, the author argues that the internalization of the supervisor's superego has the potential not only to expand the supervisee's ego (introjection), but also to repress their idiosyncratic functions and attack their thinking activity (intropression). To illustrate this argument, the author recounts his own supervised treatment of a transgender patient during which the supervisor-supervisee transference lapsed into a sadomasochistic dialectic and a folie à deux, leading to the premature termination of both the therapy and the supervision. While the initial interpretation of this experience underscored the supervisor's transphobia, the après-coup of writing up the case has revealed more complex thinking. Accordingly, the countertransference madness to which the author succumbed with his supervisor can now be understood as the unbinding of repressed infantile sexuality and the reenactment of paradoxical scenarios that the patient experienced with his parents.
