The sequel is set four years after the events of the first film and a decade before the events of The Conjuring, seeing the aftermath of Frenchie's (Jonas Bloquet) possession by the demonic entity Valak. Frenchie is also revealed to be Maurice, who dies after a failed exorcism in the first Conjuring movie.
At the end of the movie, it appears that Valak has left Maurice/Frenchie's body and that he's back to normal. However, don't forget that this movie takes place in 1956, and the events of The Conjuring—in which Maurice is exorcised by the Warrens—take place in 1968. Maurice clearly still has a little devil left in him.
By the movie's conclusion, Frenchie (who reveals his name as Maurice) is unknowingly possessed by the demon Valak. The sequel sees Sister Irene discover Valak's possession of Frenchie and supposedly free him from the demonic force.
Valak appears in multiple forms throughout the Conjuring movies, mainly taking the shape of a Catholic nun with eerie features. However, it has also appeared as the Crooked Man and its original form, Valak the Defiler.
We are aware from The Conjuring that Maurice gets exorcised by the Warrens and tries to kill his wife before killing himself. This suggests that, once possessed, a person can never be truly rid of Valak - instead, the demon just stays dormant for a while.
Sister Irene starts as a stranger and someone that Frenchie is prone to flirting with, until he finds out that she is a nun. He grows to care for her enough to try and sacrifice himself to save her from Valak's hold at the end of the movie. It is this sacrifice that leads to his own possession.
The horror film ends with its antagonist, Valak, seemingly defeated, with Maurice no longer possessed and able to build a life with Sophie and Kate if he chooses. However, the character is destined to die later in The Conjuring universe, as the demon still latches onto him during an exorcism performed by the Warrens.
Frenchie is also revealed to be Maurice, who dies after a failed exorcism in the first Conjuring movie. However, as The Nun 2 ends with Frenchie/Maurice being saved, fans have been left confused as to how he ends up possessed again nearly 10 years later.
The Nun 2 introduces a new relic to the Conjuring Universe: the Eyes of Saint Lucy, hidden in the school's chapel. Saint Lucy was a martyr who was burned at the stake by Protestants and had her eyes gouged out. Her eyes were imbued with divine power, and Valak sought them to become unstoppable.
Its ability to block Lorraine Warren's visions makes it the most dangerous spirit that the Warren couple ever met. Valak is the most powerful entity thus far in the series, as compared to Malthus the Annabelle Demon, which required a conduit to commit evil, Valak was capable of such without one.
Frenchie is intensely jealous of Derrick for this reason, though he comforts himself by noting that Derrick's braid isn't as long as his and by watching older Council members reprimand Derrick for not waking up in time to join the hunt.
Will there be The Nun 3? The Nun 3 is not yet confirmed, but there is demand and narrative potential for the franchise to continue with another installment. If The Nun 3 does happen, it is likely to be released no earlier than 2026, based on the release timeline of previous films.
Irene uses the relic against Maurice, but he grabs it, causing Valak to appear. Similar to Father Noiret, Valak lifts Irene in the air and sets her ablaze. Irene does not burn as Valak realizes she is a descendant of St. Lucy, able to harness the same power associated with the relic.
Valak seeks Saint Lucy's eyes for divine power but is ultimately defeated by the power of belief and the blood of Christ. The film hints at a possible connection between Sister Irene and Lorraine Warren, setting up future movies in the Conjuring universe.
After The Nun 2 brought back Taissa Farmiga, the relationship between Sister Irene and Lorraine Warren was finally revealed. The two are not the same person, and they might not even be sisters. However, the movie reveals that Sister Irene and Lorraine Warren are from the same bloodline.
Legend has it that Saint Lucy either plucked out her own eyes to avoid marriage to a pagan, or had her eyes put out by the Emperor Diocletian as part of her martyrdom. Eyes are also an attribute of Saint Ottilia of Alsace, a Dominican nun. Her blindness was miraculously cured during her baptism.
Meditating on the concept (and desiring to avoid CGI-heavy effects), Wan eventually settled on the visage of a nun as a character which could attack Lorraine's faith, subverting the sacred religious iconography that grounds her character and makes her feel safe.
Valak is a demon described in the goetic grimoires The Lesser Key of Solomon (in some versions as Ualac or Valak and in Thomas Rudd's variant as Valu), Johann Weyer's Pseudomonarchia Daemonum (as Volac), the Liber Officiorum Spirituum (as Coolor or Doolas), and in the Munich Manual of Demonic Magic (as Volach) as an ...
She learns that Saint Lucy's eyes, imbued with divine power, were removed upon her death and hidden within the French boarding school (formerly a monastery), where the majority of The Nun II's action takes place, and that by acquiring the Eyes, Valak would become unstoppable.
We know from the first Nun movie that at some point in time prior to the events of The Conjuring the Warrens perform an exorcism on a possessed Maurice, indicating that he seemingly still hasn't fully escaped Valak's clutches by the end of The Nun II.
Sister Irene and Lorraine Warren, both characters from The Conjuring franchise, are revealed to belong to Saint Lucy's bloodline, connecting the movies to a larger purpose.
Furthermore, while the demon that possesses the Annabelle doll isn't Valak, Valak conceivably helps this evil spirit complete its goal of possessing Janice due to how it temporarily takes the form of a nun-like figure.
Valak is said to appear as a small poor boy who has angel wings and rides on a two-headed dragon. Other ways to spell Valak's name include Valac, Ualac, Valax, Valu, Valic and sometimes Volac.
