Sedgwick is describing something the therapeutic literature routinely underplays: the therapist is not a neutral surface. The field between patient and therapist is not produced unilaterally by the patient's history arriving in the room and coating the therapist with projected figures — it is co-produced, shaped by two unconscious systems that have their own chemistry, their own valences, their own blind spots. Jung's alchemy metaphor earns its keep here precisely because alchemy insists on the transformation of both substances in the vessel. The adept is changed by the work as surely as the matter is.

What this means practically is that the "good match" Sedgwick mentions is not a logistical convenience — compatible schedules, similar cultural background, fees in range. It is an unconscious compatibility of wounds, of defenses, of what each person cannot yet see in themselves. The therapist's unanalyzed material does not politely wait outside the hour. It enters, it interacts, it either amplifies the patient's suffering or — if the therapist has done enough of the descent to recognize the territory — offers the patient a companion who knows the ground. Technique is real. Theoretical orientation matters. But underneath both of them, as Jung insists and Sedgwick confirms, the determining factor is the person holding the chair.
