After the Curse
As per orders from their employers, the Home Office, Greg and Tamara kidnap a young boy, Henry, and make their way to Neverland. While the two have always had the pretense the Home Office wants to destroy magic as they do, this is quickly disproved by the appearance of Peter Pan's Lost Boys and their group leader, Felix. From discovering the trickery, Greg and Tamara refuse to hand over Henry. Calmly, Felix sorts out the situation by calling upon the Shadow, who rips out Greg's shadow and flies off with it while Tamara and Henry are left for the Lost Boys to deal with. Though Henry manages to elude them by running further into the jungle, Tamara is caught early with an arrow to the back.

The Lost Boys give chase after Henry, but lose his trail. Henry stumbles onto another boy who claims he used to be belong to the Lost Boys. The boy's desire to escape caused him to steal Peter Pan's pixie dust, which is now the reason he himself is being sought after, too. Together, they head for the Echo Caves, but are forced towards a dead-end cliff with the Lost Boys quickly closing in on them. Though the boy insists the pixie dust is useless, Henry promises it will work with the power of belief. Dousing the pixie dust over both of them, Henry gains the ability to fly, and pulls the boy along into the air.

Once they ascend to the ground, the boy changes his demeanor, and surprises Henry by knowing his name. The boy answers the latter's confusion by revealing himself to be Peter Pan and states Henry's importance as he has the heart of the truest believer. Pulling out a blade, Peter Pan brings forth the other Lost Boys to surround and close in on a dumbfounded Henry.
