4. At All Costs (1)

Complete story — includes the ending

After repelling the Espheni attack on Charleston thanks to Volm technology, Tom, with the help of Lt. Fisher, makes contact with President Benjamin Hathaway and later decides to travel to "Keystone" to meet him along with Pope, Fisher, Bressler, and their Volm ally, Cochise. After being met with suspicion by the President and his troops, Tom explains the situation and is later asked to remain with him. Meanwhile Anne continues her suspicion about her baby Alexis and enlists the help of Dr. Roger Kadar to run some DNA tests under the guise that he's actually testing the children de-harnessed by the Volm machine. After earlier being offered the chance to have his harness removed, Ben and his friend Deni decide to remain as they are for now. Hal continues to struggle with the effect of the implant placed inside him and is later taken over. Anne, after striking Dr. Kadar and drugging Lourdes, flees Charleston after finding out that Alexis is part-alien. Anne tries to flee when confronted by a Skitter and a harnessed child in the woods, but is stopped by Hal. When the President's position is under attack by Espheni ships, Tom, Bressler, and Pope are forced to leave on Pope's plane, leaving behind Cochise with President Hathaway. As their plane is leaving the area, they are struck by an energy weapon and are forced to make a crash landing.
