It's time to discover if Cleopatra is ready to go in a mission on her own or not. She'll be able to try out her skills several times before she's into the real, dangerous situations.
Raina's such a popular gal. First the Betrayers take out Raina. Then Hal and Sarge take out Raina. Then the Baileys take out Raina. But get ready for a bang when Cleopatra takes out Raina.
Cleopatra gets trapped in a virtual reality which simulates how her life would have been if she hadn't been cryogenized after the surgery, and Mauser brings Hel and Sarge to that reality in order to rescue her.
Hal hears voices but not The Voice. Sarge hears voices and obeys them. Cleopatra learns the voice in your head may not be your own and listens to her own voice.
Sarge's origins and her relation with the surface are revealed when a mission leads Hel, Cleo and herself to a Dwork village, a group of worshipers of the Baileys.
