Warning: The following contains SPOILERS for the Gotham Knights pilot.The premiere episode of the Gotham Knights show confronts the idea that DC Comics' Batman actively seeks orphans to train as sidekicks. The matter was treated as a joke for years in superhero parodies, with it being humorously suggested the best way for an aspiring superhero to recruit a junior partner was to go to an orphanage and ask about any children whose parents died violently. Somewhere along the line, the joke was taken seriously by some writers who handled Batman, though most portrayals of the Dark Knight are sensitive towards the safety of children. This is certainly shown to be the case in Gotham Knights.
