Complete story — includes the ending
Marshall prepares to execute Tom and his family, causing them to attempt to flee. Tom escapes, but everyone else is recaptured. Lieutenant Shelton, realizing that Marshall has gone too far and is running a witch hunt, tries to relieve her of command but is killed. Marshall later meets with the Overlord who is then killed by Weaver. At the execution, Marshall's firing squad hesitates, giving Tom time to return with Cochise and reinforcements from the 2nd Mass. The 14th Virginia surrenders and Weaver kills Marshall to save Tom's life. It is revealed that the real Katie Marshall died weeks before and the one they encountered was an Espheni clone being used to weed out their human enemies in the guise of hunting for collaborators. Using Cochise as an example, Tom is able to convince the 14th Virginia that they don't have to be afraid of the Volm and need to work together, and the 14th Virginia joins with the 2nd Mass. Using his spikes, Ben is able to connect to the Espheni communications device discovered earlier and finds that the Overlords serve some kind of higher being, surprising all but Cochise as it had been believed that the Overlords were the leaders. Cochise shows knowledge of this being, but expresses surprise at its existence being real.
