He is reticent to commit troops to any maneuvers that would be deemed as an escalation especially under circumstances where it is in retaliation to any acts for whom the culprits have not been verified.
Throughout the seriesEdit
He was formerly in command of UN Fleet Command but, in "Doors & Corners", after the MCRN Scirocco destroyed Phoebe Station, he resigned his post. The UN Security Council wanted to respond to what it considered provocation when Phoebe was destroyed. Mars' moon Deimos was elected target. He was forced out for refusing to follow the order. Souther is later approached at a bar by Chrisjen Avasarala who explains his protest now prevents Souther from effectively accomplishing good. She then asks him about Fred Johnson. Avasarala arranges to have Souther reassigned as commander of the UN Jupiter Fleet or 3rd Fleet.
After recovering the UN diplomatic dropship from the Guanshiyin debris field, early in "Assured Destruction", Souther and his officers aboard Agatha King, Lt. Mancuso and Lt. Shaffer, identify Cotyar Ghazi; however, they received unusual orders from Admiral Nguyễn to detain any occupants in the brig. Accompanying Nguyễn for his interrogation of Cotyar, Souther soon develops suspicions and arranges subterfuge to question Cotyar one-on-one in order to get the real story. Realizing that Souther is scheming, Nguyen relieves Souther of command over the Agatha King.
Tensions aboard Agatha King are high after Admiral Nguyễn relieved Admiral Souther of command. Souther's loyal senior crew are talking mutiny with commanders of other ships in the fleet. After Admiral Souther receives Errinwright's message and confirms it via Cotyar, Nguyễn calls him to the command centre and relieves him of duty. Armed with the incriminating evidence, however, he cites regulations and relieves Nguyễn of command for waging illegal warfare. When Souther announces that he intends to broadcast the information to both fleets, Nguyễn and his men surprise Souther's men. In the ensuing short fight, Nguyễn shoots Souther in the chest, killing him.
