Spencer Olham: I know you're afraid. I know what they told you. That some ship got through the Dome and landed somewhere outside the city. A cyborg destroyed my body. They were right in theory, but they made one crucial error.
Maya Olham: I don't understand.
Spencer Olham: The ship crashed! You see? That's what, that's what caused the fire. They miscalculated. The Centauri never got to me.
Trivia: The uniforms worn by the ESA soldiers are the same uniforms worn by the soldiers in Starship Troopers, they've also been used in the TV show Firefly.
