Fan Casting The Boy in Legend of the Batman

Following Talia's escape, Batman joins the GCPD in searching the League of Assassins' Gotham hideout to try and find any possible leads on where she might be going. During their search, they find a young boy. He identifies himself as Damian, and claims that Talia al Ghul is his mother. He then looks at Batman and says, "You must be my father."
