This chapter explores a therapist's autoethnography and the subsequent shaping effects of his self-in-relation, for him and his therapy practice. The autoethnography employed narrative therapy's re-membering practices to (re)write into existence an enriched relationship with the therapist's deceased mother. This process produced movements through which he and his family were transformed. In Deleuzo-Guattarian terms, becoming different became possible in surprising and delightful ways that he did not foresee when he began his autoethnography. The final section of the chapter turns to how these new becomings played out rhizomatically in the therapist's family therapy.
