Monster - episode 66 - 02 Aug, 2005

Capek reveals to Nina that she and her twin brother Johan are the products of an extensive eugenics experiment which he designed to breed "the perfect children" without their mother's knowledge. When pregnant, their mother unsuccessfully tried to escape, and after the children were born they were taken away. He then takes Nina to an abandoned building where Johan is waiting. Meanwhile, Tenma drives Kristoff to a hospital while Eva demands to know Johan's location. While Eva makes a phone call to the hospital at a payphone, Kristoff reveals Johan's location to Tenma who leaves without Eva. Nina enters the abandoned building and sees Johan, and memories come flooding back of when they fled Prague, and the people Johan killed that were kind to them. (Source: Wikipedia)
