The chapter begins with Peter Pan, who is awakened in his tree home by a mysterious rapping. Despite the darkness, Peter’s adventurous spirit is immediately ignited; he admits that he "loved adventures, especially ones that placed him in danger." Upon discovering that his visitor is Tinkerbell, he learns the dire news that Wendy and the boys have been taken as "prisoners on the pirate ship." The urgency of the situation is palpable as Peter prepares to leap into action, driven by his declaration, "I must save her!"
Before Peter can depart, a life-altering confrontation occurs over a glass of water. Peter, feeling "stubborn and thirsty," ignores Tinkerbell’s frantic warnings that the water is "poisoned" by Hook. In a selfless act of devotion, Tinkerbell flies between Peter’s lips and the glass, consuming the poison herself. As she begins "spinning dizzily in the air," the severity of her condition becomes clear. She whispers a final, touching sentiment to Peter: "I love you, you silly donkey." This moment underscores the profound bond between the two, as Tinkerbell risks her life to protect the boy who often takes her for granted.
As Tinkerbell’s light begins to fade, Peter faces the terrifying realization that "she would die if it went out entirely." In a desperate attempt to save her, he relies on the magical connection between fairies and human belief. Tinkerbell gasps that she could "get well again if children believed in fairies." Peter then issues a global plea, screaming out to children across the universe, asking, "Do you believe?" and instructing them to "clap your hands" to save her. The narrative captures the collective response of children worldwide—some clapping, some hissing—until the collective effort of those who believed provides enough strength to save Tinkerbell, who returns to her "old self" immediately, showing her characteristic lack of gratitude and penchant for revenge against the dissenters.
With Tinkerbell safe, the narrative shifts back to the primary mission: the rescue of Wendy. Tinkerbell, feeling "glumly" about the prospect of saving Wendy, joins Peter as he travels across the island. The atmosphere of Neverland is described as "strangely quiet, as though it were still in shock from the recent battle." Peter searches for clues left by the boys—such as cut trees from Slightly or seeds from Curly—but finds nothing. The chapter concludes with a darkening resolve from Peter Pan. Realizing the lack of evidence and the gravity of the situation, he swears a "terrible oath," declaring, "Hook or me this time." This final vow sets the stage for the inevitable, final confrontation between the boy who refuses to grow up and his eternal nemesis.
