Complete story — includes the ending
The Martian crew passes the Errinwright recording along to Sandrine Kirino (CO) of the Martian cruiser Hammurabi. Avasarala admits Earth needs a protomolecule sample but wants to unite humanity and needs Holden's help to end the war. Naomi explains to Holden why she gave the protomolecule sample to The Belt; she has a son, Filip, in the Belt and believed that by giving the protomolecule to the Belters, it was a way of protecting her son. At the lab, Katoa tells Mao that the work on Venus is almost complete. Mao realizes that the protomolecule has an objective, orders the next subject, Mei, to be infected. Kirino gives the evidence video to Souther and explains that war is an unstable interaction between emotion, politics and luck (hence the title of the episode). Admiral Nguyen orders Mao to turn over control of the protomolecule monster missile-pods to him. Souther and members of his crew mutiny, announcing to Earth and Mars that they want to stand down and charges Nguyen with conspiracy to fight an illegal war. Nguyen kills Souther and many of those loyal to him, as others are taken to the brig. Nguyen destroys the Jimenez. The UNN ships begin firing on one another. The Hammurabi offers aid to any Earth ship willing to stand down. A wounded Nguyen launches the missile pods containing the protomolecule monsters.
