Unlike his colleagues Mercier and Rémy, the chorus-master is superstitious and open to the possibility of supernatural events such as the Phantom’s existence. Believing that the Persian has the “Evil Eye,” Gabriel hurts himself while frantically trying to flee from him. On the evening of Christine Daaé’s disappearance, he concludes that this must be the Phantom’s doing. Like Mercier, he takes part in locking up Mme Giry so that she will not interfere with Moncharmin and Richard’s efforts to discover the Phantom’s tricks.
