Room 203 (2022) Timeline Explained – Every Event in Order

Izzy becomes possessed after wearing the amulet she found in the wall hole. The amulet belonged to Karen, Ronan's mother, who was murdered by her husband Liam. The cursed amulet carries Morrigu's power and compels its wearer to kill others and ultimately themselves. Izzy's survival instincts from her turbulent past help her resist the curse's full control, but she is unable to resist completely until Kim removes the amulet.

Foreshadowing: The amulet's discovery was foreshadowed by the mysterious hole in the wall that kept expanding throughout the early part of the film.

• Izzy possession
• amulet curse
• Morrigu spirit
• haunted amulet

Ronan is the landlord and the baby who survived the tragedy that occurred decades earlier in Room 203. When Karen was murdered by her husband Liam, the baby survived. Ronan grew up to become the building's landlord, unaware that the cursed amulet his mother once wore would later be found and trigger the curse to resurface. He reveals this connection when he abducts Kim.

Foreshadowing: Milton Briggs, the janitor, earlier revealed that Karen's baby survived the murder-suicide, setting up Ronan's revelation.

The amulet serves as a conduit for Morrigu's curse. Whoever wears it becomes possessed by the crow goddess and is compelled to kill others before ultimately being driven to suicide. The curse spreads through direct contact with the amulet - Izzy begins wearing it after finding it in the wall, and it passes to other visitors who wear it, including the young man and woman Izzy brings home who disappear before dawn.

Foreshadowing: Ronan explains that the amulet belonged to his mother and that Morrigu's curse targets the necklace's wearer.

Morrigu is a figure from Irish Celtic mythology, appearing as a crow and associated with death and prophecy. Ian discovers the connection by researching the stained-glass mural, which contains Celtic pagan symbols depicting Morrigu. The window acts as a conduit for her presence in Room 203. The apartment was built or decorated with this imagery, allowing her vengeful spirit to haunt the building for decades.

Foreshadowing: The repeated crow appearances throughout the film, including one flying into the wall hole, establish Morrigu's presence early.

Ian is killed because Izzy, while possessed by Morrigu through the amulet, attacks him when he rushes to help Kim after Ronan abducts her. The curse compels the amulet's wearer to kill others, and Ian becomes one of its victims. His death occurs during the height of Iz's possession, when she has lost control to the malevolent force.

Foreshadowing: Izzy's increasingly erratic behavior and the disappearances of her guests foreshadowed the violence the curse would eventually cause.

• Ian death
• Izzy kills Ian
• possessed Izzy violence
• curse victims

Ronan becomes possessed by Morrigu after pursuing Kim and Izzy into the basement. The curse, seeking a new vessel, takes control of Ronan and forces him to turn the gun on himself. This happens during the climactic confrontation in the basement, where the curse demonstrates its power to use any wearer as a tool for death.

Foreshadowing: Ronan's revelation that he is the cursed baby and his determination to offer others to appease the curse set up his eventual possession.

• Ronan suicide
• Ronan possession
• basement confrontation
• Morrigu control

Decades before the main story, Liam McNally and his wife Karen lived in Room 203. Karen was murdered by her husband Liam, who then killed himself in the same apartment. Their tragedy created the curse that haunts Room 203. Their names were found inscribed inside a music box that Kim discovers, linking the past tragedy directly to the present events.

Foreshadowing: Kim and Ian discover the couple's story through research, and the music box with their names provides the crucial connection.

The stained-glass window depicts medieval knights in battle and contains Celtic symbols linked to Morrigu. It acts as a physical conduit for the crow goddess's presence in the apartment. The mural is directly connected to the curse's power - destroying the window is what finally breaks Morrigu's immediate hold on the apartment and allows Kim and Izzy to escape.

Foreshadowing: Ronan's first rule to the girls is to never damage the elaborate stained-glass window, establishing its significance early.

• Morrigu mural
• destroy window
• break curse

Kim removes the amulet from Izzy's neck during the climactic confrontation, which lifts the immediate danger of Morrigu's possession. The amulet is the source of the curse - without it, Izzy is freed from Morrigu's control and can regain her true personality. The curse was bound to the necklace itself, not to Izzy inherently.

Foreshadowing: Ronan explains that the amulet belonged to his mother and that the curse targets the necklace's wearer.

• remove amulet
• break curse
• save Izzy
• amulet necklace removal

The ending shows Morrigu's shadowy figure standing amid the shattered stained-glass window after Kim and Izzy destroy it and escape. This suggests that while the immediate curse has been lifted through the amulet's removal and the window's destruction, the ancient threat of Morrigu remains. The crow goddess's presence persists in the building, implying the haunting is not fully over.

Foreshadowing: Hundreds of crows swarm outside as they prepare to destroy the window, signaling Morrigu's power and lingering presence.

Izzy's sleepwalking toward the basement is caused by the amulet's growing influence over her. As she wears the cursed amulet, Morrigu's power pulls her deeper into the apartment toward the source of the curse. The basement represents the heart of the haunting where the curse's energy is strongest, and Iz's unconscious body is drawn there as she becomes increasingly possessed.

Foreshadowing: Ronan's second rule was to stay out of the basement, establishing it as a dangerous area connected to the curse.

Kim decides to write a paper about Izzy's difficult family life, specifically her mother's death from a drug overdose, because she and Ian share a passion for journalism. Kim wants to pursue investigative reporting as a career and sees Izzy's story as a meaningful subject. However, keeping this secret from Izzy creates tension in their friendship and contributes to the rift that develops between them.

Foreshadowing: This decision creates conflict when Izzy discovers the paper and confronts Kim about violating her privacy.
