Plot summary
After switching bodies with Senator Michaels and Doctor Andrew Covel, Camile Wray and Sgt. Greer are trapped within the rubble of Homeworld Command after an attack by a cloaked Lucian Alliance cargo ship. Michaels and Covel conduct reviews of the viability of another Icarus-like effort and Rush's signal findings, respectively. On Earth, Wray, Greer, and an airman named Evans fail to escape the building, but discover high radiation levels consistent with an unexploded naquadria bomb. Wray exposes Evans as an Alliance plant and Greer shoots him. They reach the bomb, but are unable to disarm it.
The crew uses an FTL jump to sever the connection for a few seconds so Varro can tell Wray and Greer how to defuse the bomb, but he runs out of time. Varro then instructs Michaels and Covel what to do and Rush severs the connection. It is unclear if they succeeded, as communication stone contact with Homeworld Command remains severed.
