The Big Picture
The Nun II effectively bridges the entire Conjuring franchise together, connecting the main films and the Nun movies.
The end-credits scene features a familiar residence in Connecticut and Ed and Lorraine Warren answering a call for help.
The Nun II establishes a connection between Sister Irene and Lorraine Warren, both descendants of Saint Lucy, with Valak continuing to haunt them.
