In his position as Deputy Chief, Pierre behaved like a typical petty official: highly obedient toward his boss, Hogarth prior to the Cult Incident, and equally arrogant to his subordinates. He was against the formation of the Special Support Section, slipping in nasty remarks in every conversation with them.
On the other hand, his henpecked situation at home caused him an enormous panic when he lost his wedding ring, which the S.S.S was tasked with to retrieve. Only when he gets drunk he complains about his wife, Margaret.
After Hogarth is dismissed as the Chief of Police and one of Pierre's subordinates is assigned as his successor, Pierre falls into a depression. He also finds out that Margaret is preparing to file for a divorce. Ultimately, they manage to steer away from an official divorce, but especially since it was leaked out he lost their wedding ring, Pierre becomes more and more submissive toward Margaret.
