The planet that Ronon and Teyla travel to is named Belkan. The inhabitants possess a disease-resistant strain of flax seed which could potentially double the crop yield on the Athosian mainland.
Goof: When Ronon meets up with his old military buddy in the bar he says "For years I believed I was the only survivor" But when he first got to Atlantis he was surprised at the images of his planet destroyed, he was obviously expecting there to still be a civilization, with many survivors.
When Weir yelled at McKay for destroying three-quarters of the solar system, he abruptly corrected her, stating it was five-sixths. You would think he would not correct that to cushion his bruised ego, since five-sixths is greater than three-quarters.
The Ancients' term for their weapon was Project Arcturus. If the project was successful it would have produced the power equivalent of twenty-five fully powered zero point modules by drawing energy from this universe rather than a self-contained region of subspace as with Z.P.M.'s.
Goof: There is a lot of debris in orbit over the Durandanes planet. All of it should have been drawn into the planet's atmosphere within 10,000 years.
Sheppard: The place won't be safe very much longer.
McKay: I can bring it back under control. Just give me a second.
Sheppard: No you can't!
McKay: One second!
Sheppard: I've seen this before, Rodney: pilots who wouldn't eject when something went wrong, trying to fix their planes (smacks desk) right until they hit the ground.
McKay: Okay, we need to leave. I've waited too long. The weapon can't discharge enough power to avoid a catastrophic overload. This whole planet is going to go up. Not that your speech wasn't working.
McKay: Harry K Daghlian.
McKay: He was a scientist -- worked on the Manhattan Project at Los Alamos. He was only twenty-six years old. Accidentally irradiated himself while performing a critical mass experiment on two half-spheres of plutonium. Took him a month to die. While his body was slowly shutting down from radiation poisoning, you know what he did with his last thirty days, hmm? He worked. He tried until his last breath to understand what had happened to him so that others could learn from the tragedy, so that his work, his death, wouldn't be rendered meaningless. Now, have you considered what would have happened if they'd just shut the Project down after that?
Sheppard: A member of your team is in the morgue.
McKay: And I am responsible for his death, yes. I am painfully aware of that. I sent him in there and I will have to live with that for the rest of my life. (His voice breaks briefly.) But we have a responsibility to understand what happened and learn from it.
McKay: Yeah, but at the end of the day the outpost was still standing and that means, uh ... well, I'm not sure what that means, but it means something definitely worth finding out.
McKay: Hold on. I'm picking up faint energy readings coming from ... (he turns back round, looks out of the windscreen and points) ... there. (He looks at the building.) That would explain how they were able to put up such a good fight.
McKay: Because ... they were Ancients.
McKay: ...and I thanked Colonel Caldwell for caring enough to spy on the experiment from orbit. Sent him a nice little email, actually. But I saved you for last because, uhm... Honestly, I would hate to think that recent events might have permanently dimmed your faith in my abilities. Or your trust. At the very least, I hope I can... I can earn that back.
Sheppard: That may take a while.
McKay: I see.
Sheppard: But, I'm sure you can do it, if you really want to try.
Sheppard: Are you sure?
Sheppard: Are you sure you're sure?
McKay: I said yes.
Sheppard: Because if you're wrong...
McKay: I'm not!
Weir: I take it you found something interesting?
McKay: Interesting? How about the greatest discovery of all times?!
Sheppard: He's pretty excited.
Weir: You believe you can finish their (the Ancients) work?
McKay: I do.
Zelenka: We do.
Sheppard: They do.
Weir: You put your life and other people's lives at risk. You destroyed three quarters of a solar system.
McKay: More like five-sixths. It is not an exact science.
Weir: Rodney, can you give your ego a rest for one second?
Zelenka: Come on, McKay, you read the equations. What else could it be, an Ancient typo?
McKay: Well, we know they're not perfect because they're all dead.
Ronon: This place, um, has everything I could want, don't get me wrong, but, uh…
Teyla: Sometimes you feel the need to go somewhere else.
Ronon: Anywhere else.
Teyla: I know the feeling.
Sheppard: Why is this outpost, if that's what it is, still intact? It doesn't make sense. What do you think, Rodney?
McKay: Hah! Sorry, I, uh, wasn't listening, but it just struck me. This is an Ancient outpost. Why would the Wraith leave it intact?
McKay: Definitely Ancient design. And their latest stuff, too. Their latest being ten thousand years old.
McKay: Okay, we've been over this. I'm doing this manually, at half power. It's a cake walk!
Zelenka: I don't think it matters how much cake you walk on. I've been doing calculations of my own…
Sheppard: Have you tried turning it on?
McKay: That's what we're working on. The problem is that there's no direct link between it and the main power control systems, which among other things, led us to theorize it's an ancillary power supply for the weapons systems.
McKay: See that? See? See the way he light up at the mention of that? It's like Dr. Vogel at the mention of pastries.
Sheppard: They found out a way to soup up their space guns.
Zelenka: Yes, but it's much more than that.
McKay: The sticking point is that there's no tie between the power generator and the primary capacitor.
Zelenka: Yeah, meaning that they would have to channel the power directly into the weapon.
McKay: Which I'm sure that means nothing to you.
Sheppard: It means they could fire multiple bursts without having to store up more power for the next firing sequence.
McKay: Yes… very good.
Sheppard: Which leads me back to 'cool!'
McKay: Look, this is big. This is the wheel... the lightbulb... the hot dog big.
Sheppard: Best-case scenario?
McKay: I win a Nobel Prize.
Sheppard: Worst-case scenario?
McKay: We tear a hole in the fabric of the universe -- which is much less likely to happen than the Nobel Prize. I mean, look, the risks are nothing compared to the potential benefits. Elizabeth will listen to you. I've never ask you for this before, but I think I've earned that. Trust me.
Teyla: That is a Hive ship.
Ronon: That was a Hive ship.
Sheppard: Something put a lot of holes in it alright. We should check it out.
McKay: Whoa, whoa, whoa - what if whatever put those holes in it wants to put holes in us?
McKay: I'm just saying, as team veteran to the new guy, heavy lunch before mission departure is a bad idea. And even with the inertial dampeners this whole flying thing is best done on an empty stomach.
According to Director Martin Wood on this episode's DVD commentary, actor Jason Momoa (Ronon Dex) insisted that the knife Teyla used on Ronon have a real blade as opposed to a fake, plastic one, so as to add to the realism to the scene.
The village seen in this episode is a redress of the village set used in the Stargate SG-1 episode, "Origin".
According to writer Damian Kindler, Ronon's lines in this episode were written before Jason Momoa was cast in the role.
The Ancient weapon room set would be redressed and used as the set for the Ancient ship, Aurora, a few episodes later.
