You start off where the last episode ended. In the cryo-chamber. Hack the emp with your phone (matching the schematic) then you will escape the chamber.
After chatting with Alfred you'll go to Bodhi Spa.
You'll then talk to a spa worker to get access to the elevator.
Once down you'll need a keycard to advance. Clear some debris on the left to get the card.
You'll meet up with Catwoman and have a conversation.
End of chapter.
