The Daedalus arrives to defend Atlantis from the Wraith onslaught, but it may not be enough when the team discovers that an even larger armada is on the way.

Production

 * This episode has actually been shot four months after.

Trivia

 * If you look very closely at the begining of the teaser (2'26"), you will see Samantha Carter wearing SG-1 clothes in the Atlantis control room background. This is confirmed by the audio commentary of the episode.
 * The prop used as a Genii A-bomb carried by Major John Sheppard in the puddle jumper in Part 3 is not the same prop as the one used in Part 2.
