Synopsis
Safely back on Moya, the crew is horrified to discover that Scorpius has made contact with Captain Braca's Command Carrier. In response they strand both him and Sikozu, who pleads for him, in deep space, knowing they'll be picked up by Braca once Moya has Starbursted away.
In return, Braca reveals to Crichton the details of a transmission intercepted from the Scarran base, indicating that the Scarrans intend to invade Earth via a wormhole. Their interest in Earth is due to an innocent remark by Crichton, revealing to Emperor Staleek that a flower essential to Scarran brain development grows there.
Crichton feverishly studies his wormhole equations to find a way to collapse the wormhole, finally solving the problem theoretically. However, his primitive human reflexes prevent him from piloting his Module accurately enough for the split-second timing that will be required.
Only Pilot is capable of flying a ship into the wormhole at just the right millisecond to cause it to collapse behind them, but Moya is more afraid than ever of wormhole travel. It looks like there’s no hope of saving Earth – until Pilot confesses that he could detach himself from Moya and steer a Transport Pod on the desired course.
Though the operation could prove fatal, Moya and Pilot volunteer, and D’Argo and Noranti begin cutting Pilot free. With the Scarran attack ship fast approaching, Pilot, Crichton, and Aeryn, who refuses to be separated from Crichton in case he doesn't make it back, make the perilous journey through the wormhole to Earth. There, Crichton takes a moment to say goodbye to his father – knowing full well it’s for the last time.
As the Scarrans enter from one side of the wormhole, Pilot plunges in, causing it to collapse around him.
The wormhole route back to Earth forever sealed, Moya recuperates in the nutrient rich seas of Qujaga. Out in a makeshift rowboat, Crichton proposes marriage to Aeryn, who gratefully accepts - after revealing that her child's pregnancy has been activated and that the baby is his.
The two embrace in happiness, but as D’Argo, Chiana and Rygel watch in horror a craft sweeps over, and blasts the two into tiny shards.
