The DESTINI Dilemma

The team discovers that the nuclear payload is too small and learns that DESTINI may have caused the crisis. Josh opposes Purcell's plan to fire the weapon.

Key Events

• Core Is Less Dense — The outer core is less dense than expected, making the nuclear payload insufficient. Characters: Dr. Josh Keyes, Dr. Conrad Zimsky, Maj. Rebecca Childs, Gen. Thomas Purcell Location: Earth's outer core
• DESTINI Revealed — Zimsky reveals that DESTINI likely stopped the core's rotation. Characters: Dr. Conrad Zimsky, Gen. Thomas Purcell, Dr. Josh Keyes Location: Virgil command compartment
• Mission Divides Over DESTINI — Purcell orders a return, while Josh argues that DESTINI could trigger massive disasters. Characters: Dr. Josh Keyes, Dr. Conrad Zimsky, Gen. Thomas Purcell, Theodore Donald 'Rat' Finch Location: Virgil communications system
• Golden Gate Destroyed — Ultraviolet radiation destroys the Golden Gate Bridge and causes regional power outages. Characters: Dr. Josh Keyes, Gen. Thomas Purcell, Theodore Donald 'Rat' Finch Location: West Coast
• Rat Blocks DESTINI — Rat redirects power away from DESTINI after Josh warns him about its risks. Characters: Dr. Josh Keyes, Theodore Donald 'Rat' Finch, Gen. Thomas Purcell Location: Communications network

Sacrifice at the Core

The crew devises a staggered detonation strategy using Virgil's compartments. Braz and Zimsky remain behind, while Josh supplies extra energy for the final blast.

Key Events

• Rat Blocks DESTINI — Rat redirects power away from DESTINI after Josh warns him about its risks. Characters: Dr. Josh Keyes, Theodore Donald 'Rat' Finch, Gen. Thomas Purcell Location: Communications network
• Compartment Detonation Plan — The crew plans staggered explosions using detached compartments and constructive wave interference. Characters: Dr. Josh Keyes, Dr. Conrad Zimsky, Dr. Ed 'Braz' Brazzleton, Maj. Rebecca Childs Location: Virgil interior
• Braz Activates Detachment — Braz enters the uncooled crawlspace and manually activates the compartment controls. Characters: Dr. Josh Keyes, Dr. Ed 'Braz' Brazzleton, Dr. Conrad Zimsky, Maj. Rebecca Childs Location: Virgil crawlspace
• Zimsky Stays Behind — Zimsky is trapped by a bomb compartment, while Josh uses reactor fuel rods to power the final detonation. Characters: Dr. Josh Keyes, Dr. Conrad Zimsky, Maj. Rebecca Childs Location: Virgil outer compartments
• Core Rotation Restored — The staggered explosions restart the core's rotation, killing Zimsky. Characters: Dr. Josh Keyes, Dr. Conrad Zimsky, Maj. Rebecca Childs Location: Earth's outer core

A Signal Through the Deep

The explosions restart the core, and Josh restores Virgil's power using unobtainium. Rat identifies the crew's whale signal, and the surviving pilots are rescued before the truth is released.

Key Events

• Virgil Regains Power — Josh uses unobtainium's energy properties to restore Virgil's power and ride the pressure wave outward. Characters: Dr. Josh Keyes, Maj. Rebecca Childs Location: Core escape path
