 Teyla has found out the Wraith armada will pass the lagrangian point satellite, the Ancient weapons platform. McKay and Zelenka think it can be repaired and powered up by using a single naquadah generator. McKay, Grodin and pilot Miller take a puddle jumper to fix it. Meanwhile Sheppard s away team is ordered to find an alternate evacuation site. Sergeant Bates has a problem with Teyla. He constantly tries to convince people it s not a good idea to take her along. He fears she will give away the location to the Wraith. A while after a heated argument between him and Teyla, Bates is found unconscious. Zelenka, meanwhile, makes a unpleasant discovery. He tells Weir the city s self destruction plan is not good enough. He s convinced that the Wraith will be able to construct an intergalactic ship with information from the remains of the Ancient database.
