Kristi and Kenny hastened to Tian Chen's abode, Kristi's heart heavy with concern for Julie. Boyd, already present, dismissed Kenny's anxiety with a shake of his head before departing, briefly engaging Jade on the porch as she lamented the vast unknown.
Meanwhile, Donna, Elgin, and Dale boarded the van, navigating their way to the RV in search of Randall's body. Deep in the woods, they stumbled upon him, alive but unconscious, his screams echoing through the foliage, paralleled by the horrified cries of Marielle and Julie.
As Boyd, Sara, and Kenny trekked through the dense woods, their path leading towards the clearing where Boyd had emerged from, defeated in his efforts to free Martin, Sara's ears began to detect the haunting melody. Her nose bled profusely, her body wracked with distress. She glimpsed the music box, its sinister presence invisible to Boyd and Kenny. Sara informed Boyd that "it" was mocking him, eager to inflict harm upon all. She implored him to silence the melody.
Back at Colony House, Donna instructed Matthias to secure all firearms in the shed, her voice firm and resolute.
Tabitha approached Jim, sharing Victor's mother's words about saving the children in the tower. She begged for his permission to venture into the woods, seeking the elusive structure. She then inquired of Victor if he knew of the tower's whereabouts, to which he shook his head, though he knew of the bottle tree's location.
Frustrated after a futile search for the music box, Kenny turned to Boyd, seeking direction. Boyd advised him to return to the town, striving to alleviate the fear that had gripped its inhabitants.
Elsewhere, Ellis and Fatima decided to seal their bond with a wedding that day, their love triumphing over the chaos that surrounded them.
At the bar, Jade struggled to reframe his perspective, searching for a new angle to decipher the enigmatic symbol. Tom materialized before him, revealing that Jade knew the symbol resided within the tunnel, its answers buried deep within its recesses.
Reggie sneaked into the shed, his eyes gleaming with malice as he slit Matthias's throat, stealing a gun from the stash before fleeing the scene.
Boyd retreated to the serene church, pouring his heart out to the Almighty before Donna's arrival. He recounted Sara's words, condemning himself for the town's newfound curse. Donna urged him to witness Ellis and Fatima's union at Colony House.
Meanwhile, Jade skillfully tied a rope to a sturdy tree and ventured into the mysterious tunnel. He stumbled upon a chamber where children were huddled together on a slab, muttering an incessant phrase. Lifting his gaze, he beheld the symbol etched in the ceiling.
Victor and Tabitha ventured into the woods, stumbling upon the enigmatic bottle tree. Victor revealed that he had found his mother there, the day after the tragedy. He imparted the tree's uniqueness to Tabitha and entrusted her with his lunch box before she entered the tree's portal, emerging in a different part of the woods. She walked for a while and stumbled upon the lighthouse.
Within the privacy of their bedroom, Ellis and Fatima exchanged vows, watched over by Donna and Boyd. As Ellis spoke of a beacon in the darkness, Boyd hastened to the trailer in the woods, retrieving the torch that had saved him from the sinister room in Season 2 Episode 2. Upon exiting, he encountered Reggie, who, blaming Boyd for the town's misfortune, shot him in the shoulder. However, Boyd prevailed, killing Reggie before he could strike again.
With the torch in hand, Boyd reached the clearing and lit it, transporting him back to the chamber. There, he heard the music box's melody and beheld Marielle, Randall, and Julie chained to the wall. Determined, he swung his fist, shattering the box and releasing the trio from their slumber.
Back in the clearing, a canine caught Boyd's attention but quickly scurried away. In town, Ethan noticed the buzzing outside had ceased.
Tabitha ascended the tower's stairs, her ears ringing with the children's haunting phrase. At the summit, the boy in white materialized and shoved her through the window.
Tabitha awoke in St. Anthony Hospital, informed by a doctor that hikers had found her three days prior, abandoned on a trail. Gazing out the window, she beheld a bustling town below, a world she had left behind.
