Four years after the premiere of the original production of Peter Pan, Barrie wrote an additional scene entitled An Afterthought, later included in the final chapter of Peter and Wendy. In this scene, Peter returns for Wendy years later, but she is now grown, with a daughter of her own. It is also revealed Wendy married one of the Lost Boys, although this is not mentioned in the novel, and it is never revealed which one she did marry. When Peter learns that Wendy has "betrayed" him by growing up, he is heartbroken until Wendy's daughter Jane agrees to come to Neverland as Peter's new mother. In the novel's last few sentences, Barrie mentions that Jane has grown up, and that Peter now takes her daughter Margaret to Neverland. Barrie says this cycle will go on forever as long as children are "innocent and heartless".
The Afterthought is only occasionally used in productions of the play, but it made a poignant conclusion to the musical production starring Mary Martin, and provided the premise for Disney's sequel to their animated adaptation of the story, Return to Never Land. This epilogue was filmed for the 2003 film but not included in the final version, though a rough cut of the sequence was included as an extra on the DVD of the film.
