Goof: For a split second, in the scene where Jackson and McKay are in the suits about to enter the chamber, a projector for one of the computer screens can be seen on the floor in the background.
The two empty suits that Rodney and Daniel discover are not actually empty as they move slightly. Someone is clearly in those suits to stand them upright.
Daniel: (to McKay) You know, it has been clinically proven that referring to yourself in the third person is a sign of mental instability, right?
On the episode, "Runner," McKay told Ford a very similar thing.
McKay: (to Ford) Although, the fact you keep referring to yourself in the third person does indicate clinic dissociation.
Jackson: I take that back -- I have met an Asgard like you before. His name was Loki. He was experimenting on humans too, until he was caught and brought to justice by the Asgard High Council.
Daniel is referring to the Stargate SG-1 episode "Fragile Balance."
We discover that Todd is at least 10,000 years old, as he said he was there when the Attero device was first activated after Janus had built it.
Nitpick: When Daniel & Rodney first look at the empty suits they are both the same height - and Daniel remarks that the insides form around whoever is in them. However when they put the suits on before going into the crystal chamber Daniel is a good 6 inch taller than Rodney.
Sheppard's plan to "jump" the Daedalus through the planet is reminiscent of the Stargate SG-1 season five episode "Fail Safe", in which Samantha Carter sends an asteroid, on a collision course for Earth, into hyperspace and through the planet.
Goof: When Ronon and Keller are trying to avoid getting detected by the Wraith, Keller has curly hair. When she is brought to Todd on the bridge her hair is suddenly straight. Then for the rest of the episode it's back to being curly.
In order for Atlantis to dial Earth, they need a specific control crystal in their DHD (making them the only ones in the Pegasus Galaxy who can dial Earth, as previously noted). Rodney states that they have obtained another Stargate, and they will be able to send Daniel Jackson home soon, yet does not mention the control crystal for the gate. With the control room destroyed at the end of the previous episode, it is highly unlikely that the crystal survived intact. One would expect that even if the explosion didn't destroy it, there should have been some sort of power surge, since the DHD controls the gate, which exploded.
McKay: Look, where does it hurt?
Daniel: Everywhere. I don't suppose there's a hospital nearby?
McKay: I'm-I'm... pretty sure we're on our own.
McKay: Look, I mean, on the bright side, I mean, we're both gonna be dead of dehydration in like five days, so you won't have to put up with me for much longer.
McKay: You know, we don't both have to go in there.
Daniel: Well, when you get killed by one of those discharges, someone's gonna have to finish the job, so... (shrugs)
McKay: Great pep talk, thanks.
Keller: We're on a space ship. Those doors are designed to be airtight. That means something as tiny as air can't even get through. How do you think you will?
Ronon: Yeah, well, I'm bigger than air.
Keller: Yeah… that's kind of my point.
Keller: What's our plan, what are we going?
Ronon: We get to an access ladder. We head down two floors to engineering rooms. Then we cripple the ship.
Keller: You… know how to do all that.
Ronon: Yeah. Don't you?
Keller: Not really.
Ronon: Watch and learn.
Keller: You can't just blast away at vital systems like that! What if you take out the life support system?
Ronon: Don't worry, the life support system is that tray. At least, I'm pretty sure it is.
McKay: Explosion diversions are the very cornerstone of diversions.
Daniel: You don't have any better ideas.
McKay: I don't have any better ideas, yes.
Marks: I got it. I'm back in. We've got control of the ship.
Woolsey: And not a moment… too late.
McKay: Hey. How are you?
Daniel: Well, it hurts to eat this fruit cup.
McKay: Don't eat the fruit cup, then.
Daniel: Thank you, Groucho.
Daniel: So you can only give compliments to the dying?
McKay: It's something I'm working on.
Daniel: You want to clear the device control room of bad guys, right?
Daniel: So why would you assume if there's a massive explosion people would go running towards it?
Rodney: I would.
Daniel: I rest my case.
Rodney: This is an Ancient facility. And Rodney McKay knows a thing or two about Ancient facilities.
Daniel: You know, it has been clinically proven that referring to yourself in the third person is a sign of mental instability, right?
Rodney: Mentally unstable like a fox.
Teyla: What should we do?
Sheppard: Five bucks to anybody who can figure out how to contact the Daedalus.
Banks: Uh, Colonel Sheppard?
Sheppard: Got an idea, Banks?
Banks: No, but I am being hailed by the Daedalus on subspace. Does that count?
Sheppard: Technically that's not your idea but good enough.
Teyla: I still do not understand what happened?
Sheppard: The gate blew up.
Teyla: That much I surmised.
Teyla: How are you?
Sheppard: Ah. Well, I'm alive, you know, that's good for now.
McKay: You wanna unzip me?
Woolsey: I'll look for a can opener.
