McKay: Look, as much as I hate to say it, Zelenka is not infallible. (edit) Weir: So we can assume the Replicators are behind this?
McKay: Well, I hope so.
Weir: You hope so?
McKay: Well, otherwise we've discovered yet another super-powerful enemy. (edit) Zelenka: That's it, we're down.
Weir: The beam still looks serious Rodney.
McKay: (worried) I know just give me a second to...crap!
Zelenka: Told you.
McKay: (annoyed) Thank you Radek, very helpful.
Weir: What is it?
Zelenka: The beam is breaking through the water much more efficiently that we thought.
Weir: The water had no effect?
McKay: It's having an effect, just nowhere near where we wanted it to. That plan took us three hours to execute and has given us an additional... (looks at watch) ten hours.
Zelenka: Nine.
McKay: Nine. (edit) Sheppard: We're gonna wreck that thing, aren't we?
McKay: What, the drilling platform? Oh hell yes. (edit) McKay: Are you sure you can do this?
Sheppard: Flying the city?
McKay: What else could I possibly be talking about?
Sheppard: I flew a V-22 Osprey once.
McKay: Was it as big as a city?
Sheppard: Well, you had to use your hands and feet for that one, for this one you just have to think... fly! (edit)

After appearing in the majority of Seasons 2 and 3, the Canadian gate tech is finally given a name, "Chuck", apparently after the actor who plays him, Chuck Campbell. (edit) This is the first appearance of Colonel Abe Ellis (Michael Beach) and his Deep Space Cruiser, the U.S.S. Apollo. (edit) This is the first appearance of Jewel Staite as Dr. Jennifer Keller, the new head of medicine. (edit) The Apollo is the fourth Daedalus-class ship to enter service. The other three Deep Space Cruisers are the Daedalus, first seen in the Season 2 Stargate Atlantis episode "Siege 3"; the Odyssey, first seen in the Season 9 Stargate SG-1 episode "Off the Grid"; and the Korolev, first seen in the Season 9 SG-1 episode "Camelot". (edit) Sheppard: Well, then I'd be "The Man" and who would I have to rage against?

In the Stargate SG-1 Season 8 episode "New Order (2)" Jack O' Neill, discovering he was to be made General and "the man" of Cheyenne Mountain, said much the same thing. (edit)

Sheppard: Well, that's why we're a team, like The Fantastic Four.

The Fantastic Four are a Marvel Comics superhero team created by Stan Lee and Jack Kirby. They first appeared in The Fantastic Four #1 in 1961, and have since been in four animated TV series (1967, 1974, 1994, and 2006), video games, and three live-action movies (1994, 2005, and 2007). (edit)
