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 with 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

Dr. Jennifer Keller: Look, after Carson... Someone had to step up and take over, and I'm glad to help out, don't get me wrong, but I'm not qualified to run a department of this size. You - you need someone... better.

Dr. Jennifer Keller: Well, a, I'm not sure that's true, and b, it's been pretty smooth sailing over the last few weeks. I think I've been lucky.

Beautiful CGI
20 February 2009 | by (London, England) – See all my reviews

This episode constitutes an extremely enjoyable season finale. However, where it really stands out is in the frankly stunning CGI that is used. Best of all is the scene showing The Horizon weapon being launched from The Apollo into the atmosphere of the Replicator's home world, travelling through re-entry, deploying the missiles which then strike the surface and explode is encompassed in one "take", the viewer/camera being allowed to drift round from several positions whilst continuously following the weapon from start to finish of its mission. It is outstanding. On top of this, later in the episode, there is an absolutely beautiful view of Atlantis at sunset, picked out in brown and gold, and then of course, the sequence with the Replicator's satellite beam striking the city shield. Whilst the story is thoroughly engaging, the visuals really make this a memorable piece of television.
