Gurney wanders back to his hut in the city, but along the way he spies The Preacher, freaking out and trashing a stall selling pictures of Chani in the marketplace. As the crowds gather and stare, Alia orders her priests to hold off on killing the heretic until it she can know with absolute certainty that he isn't her brother. The Preacher makes his way to the steps of the palace, and prepares to deliver his final sermon. "I am the Voice From The Wilderness," he cries, "and I bring you a warning. The water that we spread upon the desert has become blood. Blood upon the land which was once clean and pure! Blood in the streets of the town of Chicago! The bloody red sun of fantastic L.A.!" As he preaches, pretty much every major character fights through the crowd to reach the front row. There's Gurney, Jack, and even Alia, dressed in her very own Brown Hood Of Invisibility. Jessica, meanwhile, listens from a balcony high above. The Preacher wades out into the crowd, who part like the waters of the Red Sea to let him pass. "Only one blasphemy remains," he shouts. "And that blasphemy is Alia!" With that, he grabs her out of the crowd and rips off the hood, exposing her face to everyone around them. "Forgive me, sister," he whispers, but before she can even respond to this revelation, Jack runs out of the crowd and buries his crysknife in Muad'dib's back. There's much slow-motion shock and panic amongst the onlookers as The Preacher's body slowly collapses to the plaza's floor. Alia is dragged away by her guards, and Gurney chases down Jack to avenge his pupil's death. And then Leto emerges to cradle his father's body in his arms, as The Preacher finally acknowledges his son's paternity with his last dying breath. Leto uses worm-speed to carry the body away, and we fade to commercial over a shot of the empty plaza.
When we return, Ghanima's wedding is just getting underway. Alia presides over the ceremony from her throne, and for some reason Farad'n is escorted down the aisle by the Lady Jessica. Ghanima, however, will be escorted by Leto, who couldn't even be bothered to put on a shirt for his own sister's wedding. He does, however, stride into the throne room to announce, "Behold me, family!" before executing his own "Elaine!"-style homage to The Graduate by roaring like a sandworm from the back row of the wedding. He meanders down the aisle, declaring himself "the lion of Atreides," and informing the assembled guests that The Golden Path has officially begun. Alia is certainly not pleased by this turn of events, and she orders her guards to seize him immediately. What follows is a reasonably well-executed, basic-cable-budgeted rip-off of The Matrix, as Leto uses worm-speed to fight off a half dozen guards. This kid's definitely got a future in action flicks, though, as he seems to handle the wire-work pretty well. When the last of her guards is vanquished, Alia draws her own knife and wades into the fight. She doesn't fare any better than the others, however, and soon ends up convulsing on the floor, as she slips into the final stages of abomination. Even her own voice is gone, and the Baron takes over completely to spew venom at Lady Jessica. "Did you think I was defeated forever?" he asks. "I have her now, daughter! She is mine!" Alia struggles some more, and manages to gain just enough self-control to recognize the import of the knife Leto places on the floor in front of her. She grasps it and leaps to her feet, trying in vain to puncture the sand-trout skin which now coats her nephew's nubile chest. When she realizes that he's invincible, she slowly turns the knife onto herself. Despite the begging of the Baron, and despite the fact that in the book she ends up jumping out of a window at this point, she plunges the knife into her chest and collapses onto the floor. In a truly epic final moment of familial squickiness, her last action in this universe is to taste one of her mother's tears and whisper, "I want my brother." Yeah. We know you do. And we're really, really disgusted by it. Now just die already, for Christ's sake! And so she does. Commercial.
