It's a well-known Castithan tradition for the handmaidens to, um, service the heads of household. Jelina, a Tarr handmaiden, performs this... tradition for Datak, only to wind up dead at his front door, her eyes gouged out. Datak is incensed, but can't go to Nolan - he'd be the prime suspect and land himself back in Camp Reverie. Instead, he gets Rafe's help dumping the body in hellbug territory - and then his help hunting the perp down. Stahma's in, too - she reported the missing servant to Nolan, but he seemed too distracted by Irisa to be effective. The Tarrs decide to solve this matter like a family - a violent, bloody, vengeful family.
Considering these traits, we really wish Christie had been more discerning about whom she trusts. That Deirdre/Treasure Doll character, the one who's after Alak's pants, has been leading her astray in getting her to dress up as a Casti and dance with the disguised Viceroy Mercado. Christie is under the impression she's doing it to understand her alien husband, but when Alak finally finds out - thanks to the machinations of Deirdre - he's ashamed and furious. They have a blowout fight, sending him right into Deirdre's arms, where he encounters a different kind of blow... out.
Irisa is pleased to see her old friend, Rynn, and even more pleased that the young woman doesn't have a plan to destroy the entire town this time. She does, however have a traveling companion named Kai who, though he talks like your friendly, neighborhood insurance salesman, is the spitting image of the man from Irisa's visions of the ark that brought them here. She tries to get him to recognize her, but he's just creeped out by that "eat you with my eyes" thing she does. However, they band together, along with Nolan, when Rynn goes missing.
Nolan finds a vial near the scene of a tussle where Rynn was last seen, and Doc Yewll tells him it's a paralytic serum, meaning they should be looking for a surgeon. What she doesn't tell them is that a patient of hers came in earlier that day sporting a fancy new pair of Casti corneas. That's right - the man had alien corneas stitched onto his own. When Rafe and Datak track him down, they find he's a member of the Janus Club, the same one Christie and Mercado frequent when they want to play dress-up. He thought his stolen eyes came from a cadaver, but gives them the name of the surgeon they seek.
Nolan and Irisa arrive at the bad doctor's place of business just as he's about to remove eye two of two from Rynn. Irisa rushes him and gets a pair of scissors in the chest as thanks. She falls back, Nolan tends to her, and Doctor Peepers gets away.
Or does he? BAM! Around the corner are Datak and Rafe, ready to make good on the promise to Stahma to ensure the revenge is worse than the crime. They hand him over to Nolan and the magically healed Irisa and saunter home. Nolan's like, "Irisa, I'm really glad you're OK, but WTF? That guy just stabbed you in the chest," and she's all, "He missed." Nolan decides to get sneaky. When Irisa has her guard down, he creeps up behind her, flips her to the ground, and cuts her hand open, in the most loving way possible. The little silver and gold tendrils emerge from her palm and stitch her up. So now Nolan knows. And Irisa didn't have to tell him, which means the Irzu-Chucky character won't have to kill him. It really is a happy ending.
Except for Rynn, who's missing an eye. And a little bit for Irisa, since Kai didn't acknowledge any connection with her, even after she planted a kiss on him that transmitted the vision of the two of them on a spaceship, with the metallic weapons emerging from their bodies. And for Jelina. And the doctor who stole her eyes (even though he had it coming).
