When Zeph returns to her lair, having had her memory wiped (again), she finds a videotape that she recorded preemptively, in case she should have her memory wiped (again), which she did. Zeph on the video tells her to use a device to restore her memory, and she does. That's when the hard work begins.
Johnny gets put on laundry duty, roaming the halls for dirty undies. But while he's doing that, he's also going on liberation duty. He uses the microchip which contained Lucy and integrates it into a radio he pilfered from the guards. Now he's in.
Meanwhile, Dutch, who's been placed in solitary confinement, gets a pleasant surprise from an unseen hand. It's breakfast, plus a spoon wrapped in a napkin. Looks like someone on the outside likes her.
Zeph zaps Pree next with her re-memory serum, and he jolts back to consciousness. They put their heads together to figure out where The Lady may have stowed the Killjoys. Pree remembers there being a radar blackspot out in the saltflats. So they set a course there.
After Dutch and Johnny spring D'av from the mental ward, they break into the warden's office to get their coordinates. They find out that they're on a prison ship floating through space, and, while gobsmacked, said warden enters with her guards.
After she's dismissed her guards, the warden talks turkey. She's been sent orders to keep one of the three Killjoys alive (and we know from who). In exchange for saving all three of them, she wants them to find out who's infiltrated her prison to put a hit on a powerful inmate named Sparlow. Done deal.
In the mess hall on the inside, Dutch, Johnny and D'av are making inroads with Sparlow. That's when Korin returns from solitary, spots the Killjoys, and whips the inmates up into a frenzy. The warden steps in just in time to paralyze everyone with an electric shock, and they go down.
Zeph and Turin drop in on those coordinates and find nothing but Blackroot ships and pilots. They find that the ships have been making the same rounds for awhile, right above cloud cover. These are the ships dispursing The Lady's mind-control gas.
The warden gives the Killjoys another chance to stop Sparlow's assassination, and they find his right-hand man in the hall and intercept him. Unfortunately, someone else has gotten to him, and poisoned his food. Back to the kitchen!
