While Elisée clearly trusts Jean, other members of the group are less sure. Elisée seems not to be in the best of health, and his girlfriend, Judith, soon starts to develop an interest in Jean, feelings that Jean willingly reciprocates. We therefore have the classic dilemma of the infiltrator having split loyalties between his police role and his feelings for Judith.
The anarchists exploits become more and more daring, while Jean continues to feed intelligence to his superior. We see Jean becoming concerned as he is obliged to participate in criminality and at one point asks to be taken off the case, a request that is firmly rejected. The dichotomy has to come to an end and as you can probably imagine, there isn't a clean solution.
