In another fan theory that paints Peter Pan as someone you wouldn't want anywhere near your kids, it turns out that he is none other than the grim reaper himself, holding the hands of children on their way to heaven.
In other words, the Lost Boys never grow up because they are already dead.
Once again, the source for this theory comes from maestro J.M. Barrie, who bequeathed ownership and all rights to his story to the Great Ormond Street children's hospital.
A generous donation to help bring in long lasting revenue, or a subtle message of reassurance for all those sick kids knocking at death's door that Peter Pan is coming to whisk them away to Never-more land?
Add in that Barrie would often read his books to terminally ill kids so they wouldn't be afraid of dying, and we'd say this all seems pretty legit.
