Concepts and Ideas Update

For the scene in which Lucifer possesses Rebecca and explains to Kai his role in starting the apocalypse, I will film Emily speaking her lines as she would nromally. But later on, I will record my voice speaking the same lines. When I upload the footage and the voice recordings, I will edit the audio so that, My voice and Emily's voice will play in a synchronous manner, giving off a dual-voice effect. This is commonly seen in scenes of demonic possession in horror films. I want to use this idea to make a reference to that.
