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. (edit) McKay: Zelenka. Why can I never remember that name? (edit) 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. (edit) Beckett: Son, you don't cut leeches off, you pour salt on them. (edit) 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. (edit)

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." (edit) 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". (edit) According to an interview, this episode is one of Joe Flanigan's (John Sheppard) least favorite episodes. (edit) 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". (edit) 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. (edit)

Beckett: I'm told you have something of a cling-on.

Referencing the Klingons of the Star Trek universe. The words Klingon and cling-on being homophones. (edit)
