What Happens to Tiffany
Batman The Enemy Within: Episode 5 Choices and Outcomes
If you have been distancing yourself from Tiffany but encouraged her to join the Agency, she’ll show up at the church to assist Batman in defusing the bomb. Assuming you’re on the villain path, later on, she’ll show up at Joker’s trap room and reveal that she was the one who killed Riddler. At the end of the episode, you can choose to either talk to Tiffany yourself or have Waller arrest her. If you choose to talk to her, Batman can remind her not to forget who she is right before she gets on a helicopter to join the rest of the Agency.
On the other hand, if you told Tiffany the truth, she joins your ranks as Batman’s new partner, and she can accompany you to the crime scenes. If you’re on the vigilante path, she’ll confess to having killed Riddler right before Joker kills Waller. Near the end of the game, Batman will talk to Tiffany and you can either give her a second chance and become her mentor or turn her in to Gordon. Choosing the former will allow the two to continue to work together as partners.
