Throughout the series Edit
During "Cascade", he questions the necessity for Avasarala to continue interrogation of Draper by citing the utter non-credibility in the witness account provided up to that point by the Martian gunnery sergeant
Admiral Nguyễn orders Admiral Souther on the Agatha King to throw any survivors of the Guanshiyin found in Avasarala's UN diplomatic dropship into the brig and to avoid communications with the prisoner until Nguyễn's rendez-vous with them. He accuses Avasarala and Cotyar of treason and threatens a long imprisonment. When Souther is suspected to be scheming to access the prisoner, Nguyễn relieves Souther of his command over Agatha King. Nguyễn orders Lt. Mancuso to navigate to Io.
He later killed Admiral Souther when he announces that he will broadcast the video incriminating Errinwright and casting the war into a palor of illegitimacy. He throws all into the brig who refuse his orders. He fires on and destroys the UNN Jimenez. He kills Souther's loyal senior officers, Shaffer and Mancuso. After MCRN Hammurabi CO Captain Sandrine Kirino declares a truce to all UNN fleet ships that will join her, Nguyễn proceeds to launch the hybrids.
one of the hybrid pods launched from Prospero Station on Io is deflected by a PDC fired by Alex from the Rocinante and strikes the Agatha King. Defeated, Nguyễn watches Naomi and Alex attempt to disable the hybrids but revels in the faith that Mars is doomed.
- The nameplate showing Nguyễn's name in the "The Weeping Somnambulist" episode and in the "Cascade" episode, includes a first initial of "A" matching the first name from the books; however, in the "Assured Destruction" episode, his name appears in a communication with the Agatha King and a first initial of "G" is used. This is probably a mistake by the graphics department of the production.
