Different relational dynamics make relationships evolve within entourages. They are here mainly explored from the Caen panel, whose longitudinal dimension allows it to capture detailed movements over time. The diagram of relational dynamics identified in Chapter 3 is taken up again by detailing the main movements articulating relations, contexts and networks: polyvalence/specialization, singularization/embedding, and connection/dissociation. The ways in which these dynamics appear, their frequency, and their evolution over the time of the relationship, and over biographical time, are highlighted here.

All of these analyses raise the question of the inclusion of networks in society: do networks reproduce inequalities, do they possibly reinforce them, or do they still offer small spaces for "play" among social constraints and divisions? Do they constitute for the social sciences an intermediate level of observation, or a relatively autonomous dimension of social life, bearing its own logic and its own dynamics? We have tried here to shed light on some of these dynamics, as part of the implementation of the principles of a relational sociology.
