- Dr. Carson Beckett: My theory is that the Ancients unwittingly allowed humans to evolve on a planet with, uh, insect species on it. At some point the insects fed on humans and somehow incorporated our DNA into theirs. The Wraith are an evolution of that combination.
- Lt. Aiden Ford: So what you're saying is the Ancients actually created the Wraith?
- Dr. Carson Beckett: By accident.
- Dr. Rodney McKay: Or negligence.
- Major John Sheppard: You're saying Teyla's part-Wraith?
- Dr. Carson Beckett: A very small part.
- Dr. Elizabeth Weir: Which makes her about as different from us as you, because of the Ancient gene you possess.
- Dr. Rodney McKay: Well, and some other things!
- Dr. Elizabeth Weir: You were right.
- Dr. Carson Beckett: Lovely! About what?
- Dr. Elizabeth Weir: Your theory of the Wraith evolving after the Ancients arrived in Pegasus galaxy...
- Dr. Rodney McKay: Oh, you're kidding me!
- Dr. Radek Zelenka: Pay up.
- Dr. Carson Beckett: How d'you know?
- Dr. Elizabeth Weir: The Wraith language... It's a derivative of Ancient.
- Dr. Carson Beckett: It was very easy to miss. In fact, I couldn't even make the kind of comparison necessary to isolate the specific strand. We needed Wraith cells, which we eventually got, but then we need a full mapping of the genetic code contained within those cells, which wasn't even fifty percent complete...
- Teyla Emmagan: Please! Tell me.
- Dr. Carson Beckett: You have some Wraith DNA in your genetic make-up.
- Teyla Emmagan: That is why they are coming here. They know that Atlantis is the only way to get to a new, rich, feeding ground.
- Major John Sheppard: Earth.
- Dr. Elizabeth Weir: According to Dr. Zelenka's calculations, we have less than one week before the Wraith arrive. I want options.
- Dr. Rodney McKay: You mean besides crying ourselves to sleep? Well, not me. I haven't slept in days.
- Major John Sheppard: Granted, you guys are scientists. No one's considering putting you guys on the front line, but science can turn the tide of war. Look at the A bomb.
- Dr. Radek Zelenka: Not exactly our proudest moment.
