The bombs aren't just cute, they're also effective: they'll neutralize the nanotech running the brains of Irisa and her acolytes long enough for Tommy and Nolan to steal Irisa away from the Kaziri (big, Casti spaceship) on which the camp sits.
Amanda's second move as deputy is to find a memory card hidden in Treasure Doll's room and piece together that one of her recent customers was one Datak Tarr, father of Alak, who "kept things professional" with his employee.
Stahma does some "charity work" when she visits a terminally ill man and his daughter. Perhaps, she suggests, the girl could come be their new handmaiden, in return for the small favor of the father turning himself in for the murder of Treasure Doll?
Yes. Yes, he did. He missed the part where his ex-mistress tried to abort his baby from his wife's body, she smelled the poison (thanks to the Casti life growing in her) and killed the woman trying to wreck her life.
Tommy and Nolan get Irisa out of her compound, but she snaps awake, knocks them both out, stabs Tommy, and runs back to her goons, leaving Nolan to drag his former deputy uphill both ways back to Defiance. On a sled.
