FLASHBACK. ICARUS BASE. The Lucian troop transport and its glider escort fly down towards the base. The troops on the platforms begin to fire at them as they come into range. The gliders return fire. Inside the base, people look up in concern at the nearby impacts. At a computer in the Gateroom, Sergeant Riley calls out.
RILEY: Doctor Rush? I'm reading a dangerous energy spike in the core.
RUSH: Eli, Eli. I need your help.
WALLACE: With what?
RUSH: The ninth chevron.
WALLACE: What?! We need to get the hell out of here!
RUSH: Look, it took us two years to find this site. The properties are unique. This may be our last chance.
(The base vibrates under a nearby explosion.)
RUSH: If this bombardment continues, the radioactive core's gonna go critical.
WALLACE: Y-you mean the planet –- it's gonna explode?
