Goof: At the end of the episode, when they are through the gate, Shepard has no heartbeat and is dead. Yet you can clearly see him breath while they are trying to reanimate him!
Zelenka says several lines in Czech in this episode. First he says "Můžeš mi dát ty nejnovější data, prosim? Já se s tímhle nemůžu hnout." which translates to "Please, could you give me the latest data? I can't seem to solve this." Then he says "Ne, tak aspoň, aspoň tři mi dej." which translates to "No. Give me at least, at least three." Lastly he says "To je ono, my to máme. which translates to "That is it, we have it."
At the beginning of the episode, Lieutenant Ford mentions "threading the needle", a Jaffa expression meaning to fly through the Stargate, which was first mentioned by Bra'tac in the Stargate SG-1 third season premiere "Into the Fire".
Dr. Kavanagh's motion-by-decompression solution is the same one used in the Star Trek: The Next Generation episode "Cause and Effect". Additionally, Samantha Carter attempts to use this method to propel the Prometheus out of a nebula in the seventh-season Stargate SG-1 episode "Grace".
Goof: At the beginning of the episode it shows the Puddle Jumper flying towards the gate, and the event horizon can be seen. In the next shot McKay tells one of the crew to radio Atlantis when the gate is active, but no one does.
Goof: To get through the gate they decide to 'blow' the rear hatch (which means they just opened it, because there was no explosion heard). However, when they arrive on the other end, the door is closed.
Goof: The crew of the jumper only dials five symbols into the DHD before hitting the engage button.
The creature attached to Sheppard is later referred to an Iratus bug in the episode "Instinct".
It is revealed that objects are only transported through the Stargate in one piece. This contradicts several instances in Stargate SG-1 where a puddle shutting off well before 38 minutes cuts something in half--a Jaffa's staff weapon, the air tube leading from Ernest's underwater suit, the Goa'uld-ed Major Kawalski...)
Goof: It's a good thing that no Wraith ships detected them in the 38 minutes they were stuck in the Stargate in orbit.
Teyla: Did the doctor not say to pour salt on the creature?
McKay: I think that was a metaphor? But, it doesn't matter, just try everything.
McKay: Zelenka. Why can I never remember that name?
Weir: All right. You perceive death a certain way. I accept that, in fact, I respect that. But we do not prepare for death. We do everything we can to stave it off. That is who we are.
Halling: I am not asking you to suspend your efforts.
Weir: No. You want me to tell everyone on that ship that they should expect to die? I will not send them that message. And if you feel that violates Teyla's personal rights, I apologize, I truly do. But there's nothing I can do about that right now.
Beckett: Son, you don't cut leeches off, you pour salt on them.
Sheppard: (To McKay about the bug on his neck) What I'm trying to say is if you don't get this damn thing off me, I have even less time than you do.
McKay: Yes, Elizabeth, it's an extremely intriguing conundrum, and one that I would love to discuss with you in detail, until the Stargate shuts down and this ship is cut in two-
Weir: Rodney, calm down.
McKay: - at which point-
Weir: Rodney! If I'm going to be any help to you, I need to catch up.
McKay: If you know of some way of manually retracting the mechanism...
Sheppard: In the cockpit, on the left.
McKay: The cockpit is regrettably demolecularised at the moment.
Weir: If you waste one more minute which could be used to help the people trapped on that ship because of your ego...I promise you, I will dial the coordinates of a very lonely planet where you can be as self-important as you want to be.
Kavanagh: I thought it was important to point out the risk.
Weir: Fine. You did. Now please, worry a little bit more about their lives and less about your own ass. (Kavanagh looks away. Weir checks her watch.) Twenty three minutes.
Grodin: The Stargate transmits matter in discrete units. The front half of the ship cannot rematerialise until the whole ship has crossed into the event horizon. The Stargate is essentially waiting for the contiguous components -- meaning the Jumper and everyone inside -- to enter completely before it can transport them.
(Beckett stares at him blankly, then looks at Weir.)
Weir: He said the Gate only sends things through in one piece.
Beckett: Right. Sorry.
Weir: Alright. Let me put Kavanagh, Grodin and Simpson in a room; see what they come up with.
McKay: That's good. And the Czech, the Czech, um, the Czech whose name I can never remember.
Weir: Doctor Zelenka?
McKay: That's him. We'll work it at our end.
McKay: (looking at his watch) And we have less than thirty eight minutes.
Weir: Hold on. Why thirty eight minutes?
McKay: Because that's the maximum amount of time a Stargate can remain open in non-relativistic conditions. It's one of the more immutable laws of wormhole physics and, oh my, look at the time. It's now more like thirty five minutes. Are we all caught up?!
McKay: What am I expecting to find in here that's gonna get rid of that thing?
Teyla: Something for the pain.
McKay: I don't think Tylenol's going to do it. He needs a doctor! (He calls to the cockpit.) How much longer?
Ford: Welcome back, Sir.
Sheppard: I have to admit, it is a pleasant surprise.
Weir: How're you feeling?
McKay: Uh, he's got quite the hickey.
Weir: Don't be so methodical. Just pick one at random!
McKay: Yes, what have you got there? Any food?
Ford: You're kidding.
McKay: I have less than 20 minutes to save our lives, and I am teetering on the brink of a hypoglycemic reaction, so...
Sheppard: It's like the ugliest damn tick you've ever seen.
Weir: What could I do to help?
Zelenka: Stop talking, please.
Ford: Some sort of funky alien bug attached itself to his neck.
Weir: I'm sorry, I don't have time right now.
Halling: Neither do those people who are trapped aboard the ship of the ancestors.
Weir: News travels fast.
Teyla: My father often told stories of creatures such as this… I always thought he was just trying to keep the children from straying far from our camp.
Sheppard: Great… He tell you how to kill it?
Ford: (after he sees Teyla shake her head no) I don't know sir… I'm not sure we can.
Sheppard: Well, I could use a second opinion.
Ford: Why'd you close the door?
McKay: So that when the Stargate shuts down and the forward section is severed, we're not directly exposed to space.
Ford: Will it hold?
McKay: Like a screen door on a submarine. I just prefer hypoxia to explosive decompression. It's a personal thing!
Ford: What the hell was that? (seeing the event horizon inside of the jumper) That's strange.
McKay: Yes, it is.
Ford: That is the…
McKay: Yes, it is.
Ford: That scraping sound… we're stuck.
McKay: Yes, we are. Apparently the engine pods failed to retract in time. It's a square peg, round hole.
Sheppard: Ford, what is that?
Ford: We're stuck, sir.
Ford: In the gate.
Sheppard: You mean my day just got worse?
Sheppard: (about the place he thought was a Wraith headquarters) It's gone.
McKay: What? I thought you said it was in a mountainside.
Teyla: It was. We were inside it.
Sheppard: Let's move. (after a while) This was the spot.
McKay: (looking at a huge crater) It's more of a hole than a mountain, really.
Kavanagh: I happily left the SGC because I had had it up to here with the military running things, and you just busted me like a Private.
Weir: Don't be so dramatic. Besides, the Air Force doesn't have Privates.
Kavanagh: Neither do I. You just cut them off. Right in front of my research team.
(In the confined space of the Puddle Jumper)
McKay: Well, if you'll excuse me, I'll be a foot and a half over there taking some readings. Feel free to talk amongst yourselves.
(Ford tests alcohol on the creature)
Sheppard: Save some for me.
Ford: Wrong type of alcohol, sir.
Sheppard: What's the good of that?
Ford (after the creature doesn't react): Not much, sir.
Teyla: We should let you rest.
Sheppard: No, you should get me food.
Weir: By the way, what were you going to say?
Weir: Before, when you thought... you know.
Sheppard: Oh. That.
Weir: I didn't want you to say at the time. But now I'm curious.
Sheppard: I was going to say, uh... (long pause) "Take care of each other".
Weir: That's nice.
McKay: And, indeed we did.
Sheppard: Yes, you did. Thank you. Again.
McKay: You're welcome.
Teyla: Good night.
Weir: (after McKay, Teyla and Ford leave) You weren't really going to say that, were you?
Sheppard: I have no idea what you're talking about.
Weir: I didn't think so.
McKay: Oh, I apologize for being the only person here who truly comprehends how screwed we are!
Sheppard: Don't talk to me about screwed.
Sheppard: There's plenty of time to solve this thing, but you gotta stop using your mouth and start using your brain.
McKay: Sorry. I just react to certain doom a certain way; it's a bad habit.
Beckett: I'm told you have something of a cling-on...
Sheppard: That's funny.
