Stargate Atlantis

Syfy (ended 2009)




  • Season 4 Episode 20: The Last Man (1)

  • Ronon: Force of habit.
    Todd the Wraith: Indeed.

    This might be a reference to a previous episode of Atlantis "Midway" and tribute to Stargate SG-1's Teal'c (Christopher Judge) who appeared in that episode and quite frequently said "indeed" in his dialog.

  • Naquadah technology advanced a great deal in the 25 years McKay worked to solve the problem. The Mark XII Naquadah generators are 10 generations more advanced then the Mark II's currently being used. A single Mark XII was able to power the shield of Atlantis for nearly 400 years, after laying dormant for 48,000 years.

  • When Keller takes a splinter out of McKay, he is typically Rodney about it ("splinter acting" David Hewlett calls it) in much the same way as he did in the Season 2 episode "Conversion" when he and Sheppard were brought to the Infirmary together.

  • Other instances of time travel using a solar flare were the Stargate SG-1 episodes "1969", "2010", and the DVD Movie Stargate Continuum.

  • In the future when "Holo-McKay" tells Sheppard the history, what has happened after Sheppard disappeared, he says that all that can be prevented if and when Sheppard will return back because he would already know all what was going to happen. In the Stargate universe, when somebody time travels they create a parallel universe from the point they arrive, so all that stuff happened in that universe, but as soon as Sheppard returns he's in a different universe than the one he spoke to "Holo-McKay".

  • This is the second time that McKay talks about inventing a new kind of math. Here he believes he'll have to invent one to get the answers he needs. In the Season 3 episode "The Tao of Rodney", McKay, whose intelligence had been artificially accelerated, claimed to have created a new kind of math.

  • This is the second time that Lorne has been seen in an important position in an alternate timeline. The first was in the Stargate SG-1 Season 10 episode "The Road Not Taken" in which he was leader of SG-1.

  • This episode marks the first time we see the Asgard Beam Weapons destroy a Wraith Hive-Ship.

  • Based on estimates of the ages of the two Weirs in "Before I Sleep", a person in stasis ages one year for every (approximately) 160-165 years of real time that passes. Since he had been in stasis 700-800 years when he returned to Atlantis from the future, Sheppard was physically 4-5 years older than when the episode began.

  • The decorations in General Lorne's office include the Atlantis skyline painting he did in the Season 3 episode "Sunday". Also the name tag on his desk says General E. Lorne. The E. stands for Evan.

  • Rodney blames a recent adjustment of the Atlantis operating system for not engaging the failsafe that prevents dangerous wormholes from connecting. However, previous episodes of Stargate SG-1 indicate that is it the responsibility of the dialing gate's DHD to detect such problems, not the receiving gate.

  • Season 4 Episode 18: The Kindred (1)

  • Michael has further manipulated his DNA and no longer needs to feed.

  • This is the first appearance of Michael's Wraith Hybrids. They are his second attempt at combining Wraith and Human DNA after his first "crude" experiments that created bestial Iratus bug monsters ("Vengeance").

  • This episode reveals that Major Lorne is from San Fransisco, California.

  • This marks the first appearance of the Athosian Kanaan, the father of Teyla's child. Teyla reveals that he has the gift to sense the Wraith like she does. This will most likely make the gift very strong in her son and explain why Micheal has such great interest in him.

  • This episode reveals that the planet Hoff, first seen in the season 1 episode "Poisoning the Well," was destroyed by the Wraith after they discovered they were immune to the feeding process.

  • Goof: During the briefing on the virus Colonel Carter says "The random nature of this drug's distribution is clear and calculated." This statement is a contradiction in itself. Executive Producer/writer Joseph Mallozzi took the blame for this mistake as the line was supposed to be about "the seemingly random nature".

  • McKay: Hey, I've been cocooned inside an alien space craft, I've had another person living inside me, I've encountered, not one, but two different versions of myself....

    McKay refers to the events of (in order) "No Man's Land", "Duet", "McKay and Mrs. Miller", and "This Mortal Coil".

  • Season 4 Episode 17: Midway

  • Nitpick: The Wraith in the Midway Station control room say "the Pegasus portal", despite "Pegasus" being the Earth-given name for that galaxy. Given that the Wraith have been in Pegasus for tens of thousands of years, you would think they would have come up with their own name for their galaxy at some point.

  • The planet in the Pegasus galaxy that the Wraith used to get hijack the McKay-Carter Intergalactic Gate Bridge was designated M4F-788. The planet Sheppard and McKay use to get to Midway is M6R-125.
