Peter and Wendy
In "Peter Pan in Scarlet" (2006), the official sequel to Barrie's "Peter and Wendy", what happens to the Lost Boys when they begin to grow up is revealed when Slightly starts to grow older, as Peter banishes him to Nowhereland (which basically means that he and all his allies will ignore the banished person's existence), the home of all the Long Lost Boys whom Peter has banished in times past.
