McKay: Look, I need to be the one on the surface saving the poor bastard stuck down here, not actually be the poor bastard stuck down here. By the time Zelenka comes up with a plan, I'll have died of old age. (edit) Griffin: So, let me ask you something. As a scientist does it bother you that most of your work, no matter how brilliant, will eventually be considered misguided? ‘Cause that would bother me.
McKay: I’m sorry?
Griffin: Well, given enough time, everything’s pretty much proven wrong, right?
McKay: No.
Griffin: Everything from the Earth being flat and the sun revolving around us?
McKay: Well, if you wanna go back hundreds of years… (edit) McKay: (to himself) Wide open fields. Wide open fields. You are not stuck in a metal casket in a thousand feet of water; you are in a wide open field. (edit) McKay: (to himself) Radio transmitter is in the forward section which is now flooded with water. Which means that you have no way to contact the surface which means that they have no way to triangulate your position. Okay. All right. Been in worse situations. That you can’t think of them right now doesn’t make it any less true. (edit) McKay: (yelling at Jumper) Oh, come on! A little heat’s gonna cost me forty minutes? Is that really how you want this to go down, huh? You want me to freeze to death? You’re sure you wouldn’t rather I imploded with you, you lemon? Do you really have an opinion anyway, you, you….No! Why? Because you are an inanimate object! Does that stop me from talking to you? Oh, no, no, no, my inanimate friend. Because I have been struck upon the head! (edit)

The whale that leads Sheppard to the Jumper would later be revealed to be a Flagisallus, and not a mammal like a whale but a big fish, in the episode "Echoes." (edit) The planet in the Pegasus Galaxy that Moore and McNab brought equipment to cut through the ice and study the ocean was designated M8R-169. (edit) In this episode Zelenka speaks Czech: Do prdele, to je na hovno tohle to. Kdo to vymyslel, že budeme pod vodou, tentokrát...? This means: Damn, it's screwed up this. Whose idea was this, we'll be underwater, this time… ? (edit) According to McKay, the Jumper was sinking at a rate of 20 feet/minute. This fall rate (1/3 feet/sec.) is very slow and impacting the sea bottom at this speed seems very unlikely to damage the hull integrity of the Jumper. Further, since McKay was unable to disengage the inertial dampeners, any impact at such a low speed should have been virtually unnoticeable from inside the Jumper. (edit) Goof: As Griffin is making small talk with Dr. McKay, one of the things he mentions about Christopher Columbus is that he was the first who proposed the Earth wasn't flat. This is a a very common misconception, which seems to have come from an 1828 novel written by American author Washington Irving. In fact, the Earth was known to be round since before the time of Christ, and any educated person (including the Church and the Nobility) or even ordinary sailors would have known this around Columbus' time. What he argued was that the Earth was smaller than what everybody else thought, so a western route over the Atlantic Ocean to Asia from Europe would be a shorter than expected trip. As it turns out, Columbus was actually wrong! The Earth's size was fairly well known from the time of the ancient Greeks, and Medieval scholars had a number very close to modern measurements. (edit)

Sheppard: When the Wraith attacked the city, you were able to turn the shield into a cloak.

This refers to events in the Season 2 opening episode "Siege Part 3". (edit) McKay: (about the jumper he's in) This is the first flight this thing has had since it was shot down and repaired.

This most likely refers to the puddle jumper shot down by the prisoners in the episode "Condemned". (edit) Rodney: I’m treating an alien whale like Lassie.

Lassie is the quintessential loyal canine, she has been seen in various incarnations from original book form in Lassie Come Home in 1938 all the way to the latest film simply titled Lassie in 2005. (edit) Sheppard: Chocolate and peanut butter.

During the 70's and 80's, the Reese's Peanut Butter Cup slogan was about "chocolate and peanut butter" together. (edit) McKay: No. No, I'm not gonna fall for your plan, Lt. Colonel Siren!

In Greek mythology the Sirens were sea nymphs who lived on an island called Sirenum scopuli, which was surrounded by cliffs and rocks. Approaching sailors were drawn to them by their enchanted singing, causing them to sail onto the rocks and drown. (edit)
