Summary

Midmorning finds the entire student body assembled on the main deck, lined up by house in the same formation they used at the docks in San Alejandro. The ocean is ash gray, with low clouds promising rain—an appropriately grim backdrop for the decision ahead. Only two students are absent: Linzi, who is tending to Dr. Hewett in the sick bay, and Virgil Esparza, who holds the bridge. Ana has already briefed both of them privately.

Ana opens by acknowledging the possibility that spies are among them. Someone betrayed the school to Land Institute and sabotaged security from the inside, and that person could be standing on this very deck. But she refuses to let suspicion paralyze her, choosing to trust her classmates until given a concrete reason not to. She also outlines the security measures now in place: radio silence, confiscated cell phones (locked in a box in the captain's quarters after Tia checked them for tracking chips), activated sonar and radar blocking, dynamic camouflage, and a full sweep for hidden transmitters.

Then she delivers the revelations. She is descended from Captain Nemo—not the cartoon fish, she clarifies. The school's advanced weapons, including the Leyden pistols, are based on Nemo's technology. Harding-Pencroft and Land Institute have been waging a cold war over this technology for 150 years, and that cold war has now escalated to a full boil. The mother lode of alt-tech, including the wreck of Nemo's submarine, is supposedly located at a secret HP base three days from their current position. If LI's submarine, the Aronnax, finds them first, they're finished. And Dr. Hewett is in a coma, needing immediate medical treatment.

Ana presents two options: find the base, warn the people there, and seek help against LI—which is what Hewett wanted—or turn back to California and report everything to the authorities.

Kiya Jensen is the first to speak, questioning whether Ana is now in charge and whether the group is comfortable with that. Gem supports Ana, citing Hewett's clear orders, Ana's intuition, and her unique ability to operate Nemo tech that no one else can touch. Rhys Morrow raises doubts about whether the base even exists, suggesting Hewett—a former LI employee—could be the spy, sending them to their deaths. Ester counters that if Hewett wanted them dead, there are easier ways than a make-believe island in the middle of the ocean; if he were a spy, he'd more likely be using them to find the base and then sell them out.

Ana admits both paths carry risk. Turning back is dangerous too—the Aronnax is somewhere in these waters, and they've already seen what it did to the school. She thinks of the friends they lost, including Dev, whose crooked grin and early birthday gift—her mother's black pearl—still hang around her neck. Kay Ramsay's sister was a sophomore. Brigid Salter's brother was in the junior class. The wounded are visible among them: Eloise McManus with her arm in a sling, Meadow Newman with bandaged shoulders, Robbie Barr on a crutch with a gel cast.

The students discuss the alt-tech secret. Robbie asks if this was HP's mission all along, and Ana confirms she knew nothing until yesterday. Cooper Dunne seems eager for a rematch with LI, hoping for bigger guns. Tia Romero notes that even the sophomores knew about all this and never said a word. Ana reflects that this explains the tight security around Verne Hall, the armed guards, and the gold-level crates—and it also explains why Dev kept secrets from her, which now makes her sad rather than angry.

Brigid Salter, still shaky but iron-faced, insists they can't let LI take the base—or Ana. Gem calls for a vote to give Ana command. It passes unanimously. Ana accepts, swallowing her fear, and promises not to let them down. She orders prefects to the bridge and everyone else to their stations. Seventy-two hours remain until they either find help at the secret base or most likely die.

Character Development

Ana undergoes the most significant shift in this chapter. She openly admits she never wanted leadership—she prefers research and behind-the-scenes work to presenting. She's a week shy of fifteen, still grieving her parents and now her brother Dev, and she feels the weight of everyone looking to her for answers. Yet she chooses to trust her classmates despite the possibility of a spy among them, and she accepts the command she never asked for. Her internal monologue reveals growth: she's learned that the world doesn't care what's fair, and she has to make it care. Her promise—
