    This episode was good, but it was a little slow after coming off the Siege. I think it had a lot of character development for Weir and McKay. Basically the Atlantis Team Leaders and Weir were on their way back to Earth on the Daedulus and it was being affected by a Wraith computer virus. It was AI and killed people who were on to it and was always a step ahead. There wasn't really to much going on, it all centered around this virus. Weir wanted her love from Earth to come back to Atlantis with her, and the military wanted to replace Sheppard with Colonel Caldwell. Weir insisted that they promote Sheppard instead. So the season is moving along and hopefully some more action in the next episode!moreless
  • Some parts were flashback and Wraith computer virus take down Atlantis

    Now despite the fact that this story-line appeared in Stargate episodes you would think that i'm be disappointed but i wasn't, in fact i quite enjoyed it and how the virus managed to outsmart most Rodney idea. So that ship will be permenant fixture for this series which i'm quite happy about.

    Flashback-now i'm a bit confused with these-are these meant to be before going to. i figure before but i felt that flashback main purpose was just fill the time so they could easily have 42 minutes episodes.

    The virus was well designed but the annoying thing was it couldn't detect beforehand-all in all a average episode.moreless
  • Nothing special, but still it's good to be home...Atlantis!

    Ok there's nakes Asgard, Wraith virus and boring mumbo jumbo aboard the Daedalus, on their trip home from Earth back to Atlantis. Now i can get used to many things but this Asgard is weird, or broken: he says "crap", he curses(i think) in asgardian, and he can't break a lil' ol' wraith virus, so naturally this episode could be called Rodney McKay since he does everything. Now after such a great victory i would've wanted to see a celebrating episode or some random world exploration, not just Daedalus and viruses. Perhaps this episode was meant to feel like this, because at the end Atlantis feels incredible, you feel like you can rejoin the story again, so either the purpose...i'm just glad to see Teyla.moreless
  • After returning to Earth for a short visit the Atlantis team returns with additional replacements for the city. We learn some information about a few of the main characters and the Wraith had planted a virus on the Daedalus which has to be dealt with.moreless

    Not a bad episode but too much is covered in this one short episode.

    We have a number of storylines. Lt. Colonel Sheppard's promotion and his visit to Ford's cousin. Weir's overriding the military command and forcing them to promote Major Sheppard to Lt. Colonel. Weir's marriage coming to an end. The selection of new members for the Atlantis team as they have a fully charge ZPM and the city can support more people now. Dr. Monroe and Dr. Lindstrom are killed aboard the Daedalus on its return trip to Atlantis after they discover a virus has been infecting the computer system. The discovery is then made by McKay and the rest of the crew but McKay recognizes it as Wraith in origin.

    They try a number of times to wipe the virus without success and it takes over the navigation system and one of the 302 fighters. In the end Sheppard shoots down the fighter before it can send the Daedalus into the corona of a nearby star. This after a number of different solutions and perils are gone through.

    In other words, too much going on for one episode. It's almost as if they were trying to wrap the first season and the last three parter with one episode so they can get on with season two.

    Enjoyable with great acting and production values this episode could have been stretched out into two or shortened into one really good episode. Thanks for reading...moreless
  • Journey home...

    It was great, to be honest. A different episode - all the spaceship and journey and things what can go wrong on space, but for variety and some different - it was fantastic episode to go after the superb season start. And those little clips back to Earth and those conversations - leading only sad understanding.

    But the action on the ship and McKay - he can be... the panic and fear. And Wraith seems to be even more powerful than we thought but they managed to win this time. And the Hermiod - I start to like that little guy more and more.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (9)

    • In the DVD Commentary for this episode, Director Peter DeLuise explains that in order to make each F-302 unique they added different "good luck" charms to the cockpits. These included a toy duck, a picture of Peter DeLuise's wife and various photos of the film crew's families.

    • Landry: You were also candid enough to document several occasions on which you and the Major didn't exactly see eye to eye. In particular, there was an incident involving an alien nanovirus in which Major Sheppard directly disobeyed one of your orders.

      Landry is referring to the episode "Hot Zone."

    • Goof: The F302 fighter bay doors were opened, to try and kill Sheppard and McKay. But when they were leaving to destroy the F302 fighter outside, the doors had to be opened again for them to leave. The doors would have stayed open as the virus was still in control even after the reboot.

    • This episode marks the first appearance of Major General Hank Landry (Beau Bridges) on the series.

    • McKay: Wait a minute. There was a situation similar to this back at Stargate Command. I remember reading the report. An alien entity took control of the base computer, so they did a systems shutdown to destroy it. It survived by uploading itself onto a M.A.L.P.

      This is a reference to the Stargate SG-1 episode "Entity", which was written by Peter DeLuise, the director of this episode.

    • Goof: In the beginning, when the events of previous episodes are shown, there is no one standing at the Stargate when Lt. Ford goes through it. In previous episode, Sheppard is standing by the gate ordering Ford to stand down.

    • This is the first episode since Sheppard was promoted to Lt. Colonel after returning to Earth following the Siege.

    • Goof: When Lt. Col Sheppard is beamed aboard the Daedalus from the F-302, he is sitting down before being beamed, however, when he is beamed back on board he is standing up. Asgard beams do not re-integrate matter in a different pattern, they only transfer from one place to another.

    • Dr. Weir and her upper level staff returned to Earth and then came back to the Pegasus Galaxy. This was the return trip to Atlantis that Dr. Daniel Jackson missed joining in the Stargate SG-1 episode "Avalon (1)".

  • QUOTES (15)

    • (Sheppard in the F-302 hits the brakes and gets behind the virus infected ship)
      Weir: Nice move.
      Hermiod: Indeed.

    • McKay: Yeah. Airperson – don't be there.

    • Weir: Major Sheppard's record before he joined my team doesn't concern me. All I can tell you is that if it wasn't for him, I wouldn't be sitting here right now. And as for his rank, if that's not good enough for you, you're just going to have to promote him.
      Landry: Doctor ...
      Weir: I shouldn't have to remind you gentlemen that I continue to have the support of the President and our foreign allies. You don't wanna fight me on this one.

    • McKay: We should really really be dead by now.
      Sheppard: I don't feel dead.

    • Sheppard: (To Caldwell over the radio) You're going to have to beam us in.
      McKay: Whoa, whoa, wait a minute. The transport beam wasn't designed to transport from one point in to another inside the ship. We can end up rematerializing half inside a wall.
      Sheppard: Well, we're just gonna have to take that chance.

    • Sheppard: Sounds good. So I'm still in range right?
      McKay: (covers his earpiece so Sheppard won't hear it) Truth is, it's never been tested from this distance.
      Weir: Rodney seems to think you'll be okay.
      Sheppard: Well that's good. Wouldn't want to leave any parts behind.

    • Weir: Hey what are you doing up so late?
      Sheppard: Couldn't sleep, must be the burden of command. You know, ever since I was promoted to Lt. Colonel.
      Weir: Alright John, it's been almost a month. When are you going to stop trying to bring that up in every single conversation?
      Sheppard: You gotta understand, there's a lot of people in the airforce who never thought I'd make it past Captain.
      Weir: Well obviously the people whose opinion matters the most thought otherwise.

    • (whispering about Hermiod)
      McKay: Don't stare. He hates is when people stare.
      Sheppard: Am I the only one who thinks it's strange were working with a ailen.
      McKay: Inter galatic hyper drive technology is kinda new to us, so we need his help.
      Sheppard: Is he supposed to be naked like that?

    • Caldwell: You mean Lieutenant Colonel Sheppard.
      McKay: Ah right. That's gonna take some getting used to.

    • Inside one of the F-302s
      McKay: You know, I've never actually been inside one of these before today. It's a little, uh, cramped, huh?
      Sheppard: Just relax, Rodney. We're safe ... for the moment.
      McKay: Great. Quick question, though, just out of curiosity: how much, uh, air do these things carry?
      Sheppard: Lots.
      McKay: Uh, I'm just saying, because if this doesn't work, we'll have to go over the whole plan and who knows how long we could get stuck in here, and, and, so it-it-it would ...
      Sheppard: You know what, Rodney? You're exactly right – it's a limited supply, so why don't we conserve it by you not talking?
      McKay opens his mouth to speak. Sheppard raises a finger.
      Sheppard: At all.

    • Sheppard: This is what I do when I have problems with my laptop, I turn it off and then I... turn it on again.
      Weir: I think this is a little bit more complicated than that.
      Sheppard: I'm just saying that if we're taking a page from the John Sheppard book of computer repair, we're really desperate.

    • McKay: Crap.
      Hermiod: What did you do?
      McKay: I just ran (the virus) through a translation program. It's Wraith.
      Hermiod: 'Crap', indeed.

    • Caldwell: Are there any personnel on board who have the technical skills to do this?
      McKay: Almost everybody. That's what you get for assembling a team of brilliant scientists.

    • Sheppard: You know, Rodney, you were great back there. Wanna take the stick?
      McKay: Really?
      Sheppard: No.

    • (After being beamed aboard from the maximum limit of the beaming technology)
      Weir: Are you alright?
      Sheppard: Two arms, ten fingers... I'll check the rest later.

  • NOTES (6)

    • In the DVD Commentary for this episode, Director Peter DeLuise explains that they incorporated the color-coded crew shirts and the plexiglass status displays as they wanted the Daedalus to have the feel of an aircraft carrier.

    • When Dr. Beckett is looking through a list of candidates to join them in Atlantis you can see a couple of resumes. One of the pictures on the resume is of the director of this episode, Peter DeLuise.

    • During the syndicated airing of this episode, the opening credits from Season 1 are shown because Rainbow Sun Francks (Lt. Aiden Ford) is still a cast member until Runner (even though he doesn't appear in this episode), and Jason Momoa (Ronon Dex) doesn't join the cast until episode 3, Runner. Paul McGillion (Dr. Carson Beckett) is not credited because of this.

    • International Airdates:

      -This episode aired in Canada on July 25, 2005 on The Movie Network and September 19, 2005 on Movie Central.
      -This episode aired in the UK on October 26, 2005 on Sky One.
      -This episode aired in Australia on November 23, 2006 on Channel 7.
      -Syndication Premiere: September 30-October 1, 2006.

    • Kimani Ray Smith (Lindstrom) previously played Ocker in the Stargate SG-1 episode "Allegiance". He is also Rainbow Sun Francks' stunt double.

    • This is the first episode of the series in which Rainbow Sun Francks (Lt. Ford) does not appear.


    • Top Gun:

      When Sheppard "hits the brakes" during the engagement with the virus-controlled F-302, it's similar to Top Gun. There, Maverick is in a dogfight with a MiG-28 and he hits the F-14's airbrakes. The MiG flies right by thus giving Maverick a shooting solution.

    • HAL 9000:

      The unblinking, single red eye looking at the crew via a fish-eye lens is a dead ringer for the HAL 9000 computer from the movie 2001: A Space Odyssey.
