Deliverance (S02E11)

Having escaped containment and sent a signal to the aliens that abducted her, Chloe buys the Destiny time as the arriving alien ships draw the drones' attack. Realizing the drones receive their orders from their Command Ship, Rush and Eli succeed in blocking its signal, allowing the Destiny to slip by the drones and destroy it. While Volker and Brody work to repair Destiny's damaged shields, restoring the integrity that will allow them to jump to FTL, the Ursini in the seed ship inadvertently reveal Destiny's position to another wave of Drones. The sole surviving alien ship, unable to retreat, asks the Destiny to help fight off the incoming wave of drones. Rush suggests the Aliens agree to heal Chloe in exchange for their protection. While Scott shuttles Chloe to the alien ship a new Command Ship drops out of hyperspace and Destiny once again comes under heavy attack. But this time, Rush and Eli have a plan. (iTunes)
