The Blue Team continue their assault on the Red Team, already having destroyed most of their base. Taking cover from behind the teleporter, Gates and Miller attempt to figure out what Legend's statement about the "alien's secret weapon," meant. Claire reverts their attention on the current situation and decides to use power weapons out on the field to ambush the Blues from behind. Agreeing to the plan, Gates distracts the Blues while Claire goes through the teleporter.
After Claire emerges onto the battlefield she spots three Hornets in the sky approaching Sandbox. Quickly after, Legend, Ichabod, Gates, and Miller also take notice to them. As the Hornets enter Sandbox, one of the pilots states that they are ONC officers and orders Legend and Icky to exit their tank, which they do. As the Hornets descend, the officers interrogate both teams about the Guy in White, revealing that he is a hired hitman of the ONC. The captain of the ONC trio interrogates the Blues, who tell him that they engaged the Guy in White. However, Legend prevents Icky from revealing the Life Saver and instead tells the ONC captain that the Guy in White never mentioned it. Meanwhile, the Reds reveal that they killed the Guy in White out of self defense, after the latter killed Wilbur and Thomas and proceeded to attack them.
As a result, the officer interrogating the Reds informs the captain of this news. Suddenly, the third officer locates and shows the captain the Guy in White's Sonar Scanner, which has been broadcasting a signal to the ONC informing them of the Guy in White's location. Now having proof that both teams encountered the hitman, the ONC officers place the Reds and Blues under arrest, with the charge being: interfering with ONC affairs and concealing information. The captain then has his men electrocute the troopers and empty their weapons. Realizing that Legend has a plasma pistol, the captain orders Legend to deplete it of its energy. After reluctantly doing so, the captain electrocutes Legend and orders him to get on the Hornet. The ONC officers then fly out of Sandbox, with the Red and Blue teams in custody.
