This article will outline how interventional scenarios were constructed using the method of brief group psychotherapy through a systemic eco-constructivist approach and how new ways of understanding multiple realities and differences that underlie them arose through generative conversations directed in these scenarios. Four consultants and a psychotherapist (as mediator enablercenter) were involved in the process. Methodologically, systemic modeling, in which the therapist, drawing from his own abilities and creativity in order to generate new levels of understanding of the multiple realities, was able to shape intervention scenarios where the reason for consultation became the pretext for generating logical order changes in the levels of understanding of each of the participants. One of the strategies used by the therapist was the use of e-mail narrative, which refers to a platform on which participants in the process logged written narratives that enabled them to recount events emerging during the process and thus allowed them to enhance change. This facilitated the emergence of solutions to different problems.
