"Sir, they're right outside!?" "Then it'll be a short walk."
— Jones and Ezra Loomis arguing about the Locust assault on the courtroom
Approximately six weeks after Emergence Day, Jones was part of Col. Ezra Loomis' Onyx Guard unit that defended the courthouse in Halvo Bay from Locust assault while Loomis tried Kilo Squad for treason. As the Locust assault increased, Jones' forces began to take heavy casualties, and he called in King Ravens to evacuate the Coalition of Ordered Governments forces. He then entered the courtroom and attempted to convince Loomis to evacuate and postpone the tribunal until a later time, but Loomis cut him off and ordered him back outside. Jones was shocked, and informed Loomis that the Locust were right outside the doors, but Loomis simply responded by telling him it would be a short walk. Jones reluctantly returned to the battle, but was killed a short while later in the Plaza for the Tyran Dead. His COG Tag was later recovered by Lt. Damon Baird of Kilo Squad.
