S2·E18 Ultimatum

Marsala is kidnapped by former members of the Venus resistance, who demand that all Neo sapiens, whether loyal to ExoFleet or not, be deported from the planet. James Burns, who has been fitted with prosthetics, decides to help his sister and try to rescue Marsala alone. He is able to infiltrate the kidnappers' ranks by pretending to be sympathetic to their cause, and later tries to sneak Marsala out. Some Neo sapien holdouts attack the encampment, and though James is able to save Marsala, it is at the cost of his own life.
