- In Gaston Leroux's original novel, it is hinted that the Phantom was Christine's biological father, which can explain his intense connection to her. While his true identity had always been ambiguous in the book, this possibility remains one of the driving forces behind his actions and emotional attachment to Christine.
Please note that this idea of shared parentage between the Phantom and Christine appeared exclusively in Leroux's novel during its early serialized publications; the plot element was discarded during later revisions. Its omission from subsequent rewrites leaves the Phantom's identity unresolved and emphasizes the mysterious origins of his character in the novel.
