With the movie's Easter egg seemingly confirming the fan theory, director Michael Chaves has opened up about The Nun II's Sister Irene and Lorraine Waren connection. The latest chapter in The Conjuring Universe saw Taissa Farmiga's Sister Irene tasked with investigating a series of murders of priests in France seemingly tied to the demon Valak, despite having defeated the entity in the prior movie. During her confrontation with Valak in the finale, the demon tries to light Irene on fire, with her successfully remaining unburned and a flash of Lorraine's eyes lining up with Irene's as she becomes determined to defeat the being.
