Family consultations with the L. family revealed how adolescent processes constitute a sort of vector which gives shape to different drive activity within the family. Analysis of the family’s psychical metabolism, sibling disputes, the impact of inter-generational, transgenerational, and extra-familial conflicts, showed that the adolescent processes in Thomas, Mme. L.’s thirteen year-old son from a previous marriage, exercised a kind of attraction over the family’s implicit violence. The inner rupture of development in the young teenager also causes a rupture of unconscious alliances among the members of this family.
