A Gemenese polytheist terrorist group captures and boards the shuttle. They take the passengers hostage. They begin executing them in the names of their gods unless the kids repent of their monotheist beliefs and turn back to polytheism.
Lexon, Lacy and Odin Sinclair stop the hijackers from executing more passengers. It is later revealed that this was an STO test of how strong their monotheist faith is. No one was actually killed. Those deaths were faked and dummies were jettisoned into space. ("Blowback")
At the camp, Lexon is late for Kevin Reikle's weapons class. He runs past a guard without saluting. The guard yells at Lexon to salute and the two get into an altercation. The guard tells a U-87 robot to execute Lexon. Lacy witnesses this and tells the robot to stop, which it does. The guard and Lacy go back and forth ordering the robot. The cylon ultimately follows Lacy's orders and Lexon's life is spared. ("The Heavens Will Rise")
The Gemenese native tongue is the Romanian language (per the DVD commentary).
