Col. Abe Ellis arrives at Atlantis with a new ship, the Apollo, and important news: a new Replicator base has been detected and it appears they have been building a new fleet of ships. He is under orders to destroy the Replicator base and while Dr. Weir doesn't agree with the plan and would prefer to negotiate with them, it's clear that the decision has already been made. The mission seems to go off without a hitch but when a gate appears above Atlantis, the city finds itself bombarded by a deadly ray. Their first attempt at saving the city proves to be temporary at best and they are left with only one choice: activate the city's hyper-drive and leave the planet. Meanwhile, having been bypassed in the decision to attack the Replicators in the first place, Dr. Weir questions whether she can continue as head of mission but fate intervenes. Written by garykmcd
