Warning: This article contains spoilers for Insidious: The Red Door. As Insidious: The Red Door proves, it wouldn't be an Insidious movie without the return of psychic paranormal expert Elise Rainier. Lin Shaye once again portrays the medium with close ties to the Lambert Family for the fifth installment in the franchise, which takes place ten years after the events of Insidious and Insidious: Chapter 2. Elise also appeared in Insidious: Chapter 3 and Insidious: The Lost Key, both of which added more backstory to her character and expanded on the world-building and lore of the franchise by showing aspects of her childhood and spectral experience prior to meeting the Lamberts.
