Beware the Batman S01E10 - Sacrifice

After stealing a valuable package from the League of Assassins, Anarky makes a deal with Lady Shiva to steal a deadly virus, in return for her "package." At the same time, he informs Batman where he can find Lady Shiva: the Gotham Contagion Research Center (a building that handles rare and deadly viruses). Although they know it's a trap, Batman and Katana go anyway. Once inside, Anarky releases one of the airborne viruses into the building. Now Batman, Katana, and Lady Shiva have to escape the building before its breach protocol is initiated, while staying ahead of two mutated assassins. In the end, Anarky gives Lady Shiva back the package he stole which contains the body of Ra's al Ghul.
