Count Philippe proves a deeply responsible, conscientious adult through the commitment he demonstrates to raise his younger brother, Raoul, and introducing him to the world of high society. A well-educated, noble man, Philippe, who is ballerina Sorelli’s lover and enjoys the musical entertainment at the Opera, remains attached to upper-society norms. As a result, although he is initially amused by Raoul’s infatuation with Opera singer Christine Daaé, he ultimately disapproves of his brother’s desire to marry her, since Christine does not belong to nobility. When he hears Raoul rave about a mysterious Erik, he worries about his brother, wondering if Raoul has gone insane. However, Philippe still proves devoted to his brother’s cause when he remembers Raoul’s claim and enters Erik’s secret retreat to follow his brother. He ultimately dies while trying to cross the underground lake that sits beneath the Paris Opera House. It remains ambiguous whether Erik actually meant to kill Philippe or whether, as Erik claims, the man was already dead when Erik found him on the lake.
