Senator Michaels (KATHLEEN QUINLAN) and Dr. Andrew Covel (FRENCH STEWART) visit Destiny to verify Rush's (ROBERT CARLYLE) mysterious data and determine the viability of another Icarus base. Greer (JAMIL WALKER SMITH) and Wray (MING-NA), using the communication stones, find themselves in the midst of an alien attack when an alien ship crashes into Homeworld Command. Trapped inside the collapsing building with no way in or out, Greer and Wray learn from Telford (LOU DIAMOND PHILLIPS) that the crashed ship is emitting radiation, likely from a bomb. They have no choice but to attempt to diffuse the bomb that threatens the entire district. Unable to disconnect the stones, Rush discovers not everyone want Greer and Wray back aboard Destiny.
