Unbeknownst to Christine and Raoul, Erik has been watching them and overheard their whole conversation . </P> <P> The following night, the enraged and jealous Erik abducts Christine during a production of Faust and tries to force her to marry him . Raoul is led by a mysterious opera regular known as "The Persian" into Erik's secret lair deep in the bowels of the opera house, but they end up trapped in a mirrored room by Erik, who threatens that unless Christine agrees to marry him, he will kill them and everyone in the Opera House by using explosives . Christine agrees to marry Erik .
