D’Argo, Chiana, Rygel and Jool decide to flee while they still can. No sooner have they reluctantly agreed to abandon ship when Crichton bursts in on their meeting and reveals his new plan. Surprisingly, it is Rygel – the only one of them who witnessed the horror of the Scarrans’ use of wormhole technology - who convinces them to change their minds and agree to help Crichton.
