 Two hive ships are still approaching Atlantis and all hope seems lost. Weir orders evacuation and she and Sheppard activate the city s self destruct. Just when McKay tries to dial the address of the evacuation site, the stargate activates from off-world. All of the sudden help from Earth is under way as a certain colonel Everett arrives with reinforcements. Immediately he gets under everybody s skin. He relieves Weir of command, orders her and Sheppard to cancel the self-destruct and get the evacuated people back. He tells Earth has constructed a new intergalactic battle cruiser, the Daedalus, that will arrive in four days, bringing a ZPM. He brought some supplies to defend the city until then, naquadah powered gun turrets and an improved naquadah generator to power the weapons chair. He also deploys some space mines to keep the hive ships at bay. Will it be enough?
