Marsala is taken to Phaeton, who is hesitant to believe that Marsala has changed sides. Marsala captures the rest of Able Squad, and Phaeton has Marsala conduct a brain scan of Marsh to determine if his defection is deception. When Marsala is given the opportunity to execute his fellow squad members he makes an impassioned speech regarding the plight of the Neo sapiens, but then turns against Phaeton.
