The Nun II Ending Explained: How Sister Irene Finally Defeated Valak at Saint Lucy’s School

Spoiler Warning: This article reveals major plot twists from The Nun II (2023) and its ending.

Valak is back, and this time, Sister Irene faces a demon that wants more than revenge. In The Nun II, the terrifying nun hunts a powerful religious relic hidden beneath a French boarding school. But the biggest twist is that Irene’s connection to the relic may be the one thing Valak cannot overcome.

Here’s how Irene and Sister Debra turn the tables on the demon—and why the ending still leaves a disturbing question.

Why Does Valak Target Saint Lucy’s Descendants?

Set in 1956, four years after the first film, The Nun II follows a new series of brutal deaths across Europe. Irene discovers that the victims share a connection to Saint Lucy, a Christian martyr whose eyes were removed before her death.

Valak wants Saint Lucy’s eyes, believing the relic can restore the power it lost after being cast out of Heaven. Its search leads to a boarding school built on the site of an old monastery.

Unfortunately, Maurice—also known as Frenchie—is working there, unaware that Valak still possesses him.

How Does Irene Find Saint Lucy’s Eyes?

Irene investigates the victims with Sister Debra, a young nun whose faith is still developing. Their research reveals that the relic was hidden beneath the school’s chapel.

A stained-glass image of a goat provides an important clue. When light shines through its eyes, it points toward the relic’s hiding place.

Irene and her allies eventually uncover Saint Lucy’s eyes. But Valak attacks before they can safely protect them, and the demon manages to seize the relic.

Why Can’t Valak Burn Sister Irene?

During the final battle, Valak uses the relic’s power and attempts to burn Irene alive, just as it burned Father Noiret earlier in the film.

But Irene survives the flames.

She then remembers her mother’s unusual visions and realizes that she is a descendant of Saint Lucy. Her mother’s words, “You have my eyes,” carry a deeper meaning: Irene shares the saint’s bloodline and the spiritual connection associated with it.

This revelation explains why Valak’s fire cannot destroy her. The demon has gained power from the relic, but Irene possesses a connection that makes her far more difficult to defeat.

How Do Irene and Debra Defeat Valak?

Irene realizes that she and Debra must rely on their faith rather than physical strength. Together, they recite the sacred Words of Institution over spilled wine in the room.

The wine transforms into the blood of Christ, flooding the area and engulfing Valak. The demon is burned and banished, ending its immediate attack on the school.

Their victory also completes Debra’s emotional journey. She began the story questioning her faith, but standing beside Irene helps her discover what belief means to her personally.

Is Maurice Finally Free From Valak?

For a moment, it appears that Maurice has been saved. He returns to himself and reunites with Kate and Sophie, the mother and daughter he has grown close to.

But Irene watches him leave with a worried expression. Her reaction suggests that she is not entirely convinced the demon’s influence has disappeared forever.

Fans of the first The Nun already know that Maurice’s possession connects to the Warrens’ later investigations in The Conjuring. So although Valak is defeated in this battle, the ending does not promise that the danger has vanished permanently.

What Does the Ending Mean for The Conjuring Universe?

The film expands Irene’s role by revealing her connection to Saint Lucy and suggesting a possible spiritual link to Lorraine Warren, who also experiences visions.

It also explains why Maurice remains important to the larger franchise. Valak’s connection to him helps bridge The Nun II with the events of The Conjuring.

The result is a victory with an unsettling shadow: Irene has saved the school, but Valak’s story is not finished.

Final Thoughts

Sister Irene defeats Valak by combining courage, faith, and her newly discovered connection to Saint Lucy. With Debra beside her, she turns the demon’s stolen power against it.

But Maurice’s uncertain future keeps the ending from feeling completely safe. Valak may have lost the battle at Saint Lucy’s school, yet the wider Conjuring Universe makes one thing clear: evil rarely stays buried for long.
