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....
Ronon: How can you eat right now?
McKay: Kidding? It's the first decent meal I've had all day. Besides, we're not gonna help Teyla at all starving ourselves. I'm just trying to keep my strength up. I suggest you two do the same.
Keller: Wait – you're not seriously thinking of giving him our research on the Hoffan protein?
McKay: Well, why not?
Keller: Because we'd effectively be giving the Wraith the means to reproduce the drug and potentially infect and kill millions.
McKay: Theoretically, yes, but practically it really wouldn't be in their best interest to poison their own food supply, regardless of whether our research helped them to come up with an antidote or not. No, I think the more likely scenario is that they find an antidote that works as a short-term solution to the existing threat, then they work on weaponising the protein – you know, coming up with a more effective delivery system, one that cuts out the middle man – in this case, the human victims. No, what we're doing is giving them the means to kill each other off.
Sheppard: So, when you put it that way, giving them our research could be a good thing.
Sheppard: (About Michael) The other Wraith didn't want anything to do with him, so he's been kind of holding a little bit of a grudge ever since.
McKay: He's not a big fan of humans, either. For him, the Hoffan drug is the perfect weapon.
Lorne: I don't give a damn about your trade secrets. We wanna know where you got this stuff.
Trader: And if I don't tell you, what are you gonna do? I recognize those uniforms; I've heard the stories. People from Atlantis – do-gooders of the galaxy. You wouldn't hurt me.
(Teyla steps out of the darkness.)
Teyla: I'm wearing no uniform.
Trader: A pregnant woman! Very intimidating!
Sheppard: (About Wraiths offer) That's not gonna happen.
Todd: You always say that – but you always come around.
Sheppard: (seeing corpses) Well, let me guess: something they ate.
Todd: Many of my fellow Wraith have fallen victim to this attack on our food supply.
Sheppard: Yeah, it's a shame; but it's not really our problem.
Todd: From what we have been able to surmise, this blow against us has been delivered at great cost to human lives – something you would have made your problem in the past. Unless, of course, you're responsible for the dispersal of this plague – in which case you may well consider the human lives sacrificed acceptable losses.
Sheppard: Actually, when we were putting the list together of the most likely suspects, you were at the top.
McKay: You're sure it's the same protein?
Keller: I ran a side-by-side comparison. It was almost an exact match.
Keller: Well, we're dealing with the new and improved version. The Hoffan drug killed roughly fifty percent of the test subjects, and this one kills only thirty percent.
Sheppard: Yeah, it's still thirty percent too many.
McKay: (just returned from infected planet) Oh, it's disinfectant.
Sheppard: We just came back from the bio-screen, Rodney. We were wearing Hazmat the whole time, too.
McKay: Yes, well, it's better safe than sorry.
Sheppard: Nope. The place is cleared out.
McKay: Is that what I think it is?
Carter: It's getting to be a familiar sight.
Ronon: What is it?
Carter: A Wraith subspace tracking device. It's our old friend.
McKay: Oh, Todd!
Carter: Maybe he wants to talk, and maybe he just wants to lead us into an ambush. There is always that possibility.
Sheppard: Well, there's only one way to find out.
McKay: Oh, come on! We just got back!
Carter: Sorry, Rodney.
McKay: I haven't had lunch yet.
Keller: ...Well, maybe the Hoffans have resumed distribution of the drug, but on a much larger scale?
McKay: They haven't been doing much of anything lately. When the Wraith discovered what they were up to, the whole civilization was wiped out.
Sheppard: Maybe a few of them survived, and are planning a little payback?
Carter: The random nature of this drug's distribution is clear and calculated. It's obviously intended to throw the Wraith completely off balance. They have no way of knowing which of their food sources has been infected.
McKay: So, it's just a matter of time before they become hungry and cranky!
(all look at McKay)
McKay: Well, I mean, I know I would.
McKay: Something wrong?
Teyla: Er...I was debating whether or not to tell anyone.
McKay: Tell anyone what?
Teyla: I believe I had a vision, last night.
McKay: A vision?
Teyla: I saw Kanaan, the father of my son. I believe that he was trying to...send me a message, that he's alive, and that I must not abandon the search for him and the rest of my people.
McKay: And this was while you were sleeping?
Teyla: You think it was a dream?
McKay: Well, I, I...
Teyla: I believe it was more than that. It did not feel like a dream.
(McKay looks skeptical)
Teyla: I knew you would doubt me. I should not have said anything.
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, so who am I to judge? If you say it was a vision then I believe it was a vision.
McKay: (quick cut to McKay & Sheppard) I seriously doubt it was a vision.
Teyla: I purchased the pendant from an artisan in Croya, the village we are about to visit. Among the Athosians it's quite common to present such gifts as expressions of admiration and respect.
Ronon: Hey, maybe I'll pick you something up while we're there.
Teyla: You're insane.
Michael: Spite me all you want, but don't do it at the expense of the child.
Teyla: My child is of no concern to you.
Michael: On the contrary, I have great plans for him.
Todd: Obviously there's more you want from me or you would not have come.
Ronon: Maybe we just came to kill you.
Todd: Did you?
Sheppard: Unfortunately, no.
Todd: Well, there's always next time.
Patrick Sabongui (Kanaan) previously played the Taliban Guard in Sheppard's flashback in the episode "Phantoms."
The working title of this two-part episode was "Rise of the Googlions". It was invented by writer Carl Binder, and has no particular meaning.
Rachel Luttrell voiced the "Previously on Stargate Atlantis" line.
Paul McGillion's name is withheld until the end credits to conceal his "surprise" appearance in the closing moments of the episode. Much the same way, Torri Higginson's name was withheld during the opening credits of "Be All My Sins Remember'd" earlier this season.

Todd: There can be only one.
This is the famous tag line of the cult film Highlander (1986), its sequels, and the television series, Highlander: The Series (1992 - 1998), that spawned from it. All are about immortals whose lives are spent mostly being part of 'the Game' - challenging other immortals to sword fights in order to behead them and be the only one left in order to win the ultimate and mysterious Prize.
