1x49 - Peter Pan & the Pirates

Peter and the Lost Boys cause a commotion among the pirates when they steal the Jolly Roger's flag. In trying to retaliate, Hook puts too much gunpowder into Long Tom and gets blown to smithereens. The rest of the pirates decide to leave Neverland since their captain's vendetta with Peter was the only thing that kept them there. Peter is devastated that Hook is dead and the pirates are gone. But he may just get one last showdown with his archenemy when the Lost Boys tell him that Hook's ghost now haunts a cave.
