Stargate Atlantis

Season 5 Episode 20

Enemy at the Gate

Aired Friday 10:00 PM Jan 09, 2009 on Syfy



  • Trivia

    • Nitpick: The clip of Woolsey saying "Keep firing, Dr. Beckett!" is used twice, once immediately after the hive returns fire on Atlantis and once when the battle pushes Atlantis into Earth's atmosphere.

    • Nitpick: Why were any of the SGC amazed to find out the darts would kamikaze into area 51 when that has been the Wraith's main strategy in lots of other episodes?

    • Goof: Kavanagh's name is misspelled "Kavanaugh" in the end credits.

    • General George Hammond is said to have died from a heart attack. The actor who portrayed him (Don S. Davis) died June 29, 2008 also from a heart attack.

    • Nitpick: When the Atlantis team members are looking out onto the Golden Gate Bridge, Woolsey welcomes Ronon to Earth and no one else. Ronon has previously been to Earth before in the Season 3 episode "Sunday", Season 4 episodes "Miller's Crossing", "Outcast" and "Midway". If he was only welcoming alien visitors to Earth, he'd welcome only Teyla and Ronon, but at that point Teyla was already looking out to the bridge and Ronon had just walked up.

    • In a tactic used often by the Goa'uld, the Wraith have a Stargate on board their ship to prevent Earth from Dialing out. In this case as it's a Pegasus Gate it takes precedence over the Earth Gate as the dominant Gate to prevent Earth's gate from working at all.

    • Atlantis has returned to Earth and is floating off the entrance to the San Francisco Harbor, in a military exclusion zone and is cloaked.

    • The Ancient Chair from Antarctic Outpost, now in Area 51, was destroyed by the Wraith.

    • In the previous episode, it was shown that in the alternate reality the Ancient Chair from the Antarctic outpost had been moved to Area 51. This information was included in the sub-space message by the stranded Wraith, which is why the Wraith target it in this reality. Unfortunately in this reality it has also been moved to Area 51 just one month earlier. It was moved due to it being in violation of the non-proliferation arms act of the Antarctic.

    • The Odyssey was unable to help in the battle against the Super-Hive Ship as it is off on a secret mission somewhere.

    • In this episode, another Hive ship is destroyed by Atlantis. This brings the total to 29 since the expedition arrived in the galaxy.

    • Although it is not seen, this episode introduces a new Earth ship, the Sun Tzu, a Chinese ship. It is the fifth Daedalus-class ship to enter service. The other four Deep Space Cruisers are the Daedalus, first seen in the Season 2 Stargate Atlantis episode "Siege 3"; the Odyssey, first seen in the Season 9 Stargate SG-1 episode "Off the Grid"; the Korolev, first seen in the Season 9 SG-1 episode "Camelot"; and the Apollo, first seen in the season 3 Atlantis episode "First Strike". Carter reveals to Sheppard that she is leaving the SGC to command the next ship in the line, formally named the Phoenix in the alternate timeline in "The Last Man", which has been renamed to the General Hammond in honor of the General who has recently died (in a homage to actor Don S. Davis, who passed away shortly before filming of this episode).

  • Quotes

    • Woolsey: Well, here we are again.
      Todd: Indeed. This city has become… quite familiar to me. Almost a respite from daily life. It would be a shame to see it destroyed.

    • Todd: I may have acquired a few more then I let on.
      Woolsey: How many more?
      Todd: Let's not get caught up in unnecessary details.
      Woolsey: I'd like… details.

    • McKay: Kavanagh. What the hell are you doing here?
      Kavanagh: Reassignment. More fun and adventure in the Pegasus galaxy.

    • Harriman: We've been trying to dial up the Alpha site, to send through those IOA dignitaries.
      Major Davis: Good old IOA. Courageous to the end.

    • Wraith: I restored your life, human, and bound your wound.
      Ronon: That was real nice of you.

    • (about Todd's credibility for the ZPMs)
      Woolsey: He actually came through for us.
      Sheppard: Maybe he's turning over a new leaf.
      Woolsey: Get those down to Zelenka immediately.
      Lorne: Yes, sir.
      (Lorne starts to leave.)
      Sheppard: Or maybe they're going to blow up when you plug them in.
      Woolsey: (changing his mind) Have Doctor McKay check them first.
      Lorne: Right...

    • (after Sheppard comes back for Ronon who died but was brought back to life)
      Sheppard: How ya doing, Chewy?

    • (last words after being back on Earth)
      Sheppard: Nice view.
      Woolsey: Yes. Yes, it is.

    • Keller: (to Rodney) You okay?
      McKay: (dryly) I'm alive.
      (Jennifer laughs. McKay puts his arm around her, pulling her close.)
      McKay: And I've got you. What else do I need?

    • (Sheppard goes to the infirmary to see Ronon)
      Sheppard: Well, how you feelin'?
      Ronon: I'm ready to get out of here.
      Sheppard: Take your time. The city's pretty banged up. Even with the ZPMs, we're not going anywhere for a while.
      Ronon: And when they fix it? Do you really think they're going to let us take it back to Pegasus?
      Sheppard: I'll make sure you get home.
      Ronon: This is my home.

    • Carter: Walter, you'd better get me the President. It looks like Atlantis is coming home.

    • (McKay makes some final adjustments on a control panel.)
      McKay: (into radio) All right. I've finished recalibration on the chair. Radek, how are things at your end?
      Zelenka: (over radio) ZPMs are online and functioning one hundred percent. We're good to go.
      McKay: Okay! Who's flying this puppy?
      (Beckett quickly enters the room.)
      Beckett: That would be me.
      McKay: (confused) Carson?
      Beckett: Rodney.
      McKay: What, they called you in for this?
      Beckett: Aye.
      McKay: You must have a higher CIA than I thought.
      Beckett: Excuse me?
      McKay: Chair Interface Aptitude. We have a... we have a ranking system.
      Beckett: Well, apparently, after Colonel Sheppard, I'm number two.
      McKay: (skeptical) Really? I'll have a look into that.

    • Banks: Incoming wormhole. Signal's coming in now.
      (They look on a monitor to see a video transmission of Todd)
      Sheppard: (taken aback) Todd.
      Todd: No doubt you're surprised to see me, John Sheppard.
      Sheppard: Well, you weren't looking so good last time I saw you.
      Todd: Yes. Well, you'll be pleased to know the treatment was successful, although excruciatingly painful.
      Sheppard: You're just saying that to make me feel good.

    • Sheppard: The other ZPMs you talked to Woolsey about? Tell us where to get 'em, and maybe it'll improve your situation.
      Todd: Am I supposed to be enticed by this offer?
      Sheppard: No. I'll probably kill you anyway. But, don't forget, this Wraith betrayed you and got away with it. For no other reason, you might want to do it out of pure spite.
      (Todd leans back, studying Sheppard.)
      Todd: You...know how to talk to me, John Sheppard.

    • (while talking to Todd)
      Sheppard: Here's the problem. Every time we get involved with you, I feel like I'm walking around with a live grenade in my pocket, just waiting for it to all go wrong, for that one thing you forgot to mention.

    • Sheppard: Question is, what will happen next time.
      Todd: Is there going to be a next time?

    • Sheppard: Do me a favor, when Atlantis shows up, tell them I said goodbye.

    • Woolsey: Ronon, welcome to Earth
      (Everyone looking out at the bridge)
      Keller: No one can see us, right?
