How does the Phantom suddenly appear in Christines mirror, which still shows her reflection?
[O.P & L.V] It works much like the mirrors you see in police movies, when you can see through one side and not the other. The Big Brother House also uses the same kind of mirrors so its cameras can see the house without people seeing in. When lit from the front, the mirror seems as if it is normal and the audience can see Christine’s reflection.
