Nitpick: Janeway states that Q's one redeeming quality is that he's never been a liar. However, in The Next Generation's "Deja Q", Picard specifically refers to him as a liar. In Deep Space Nine's "Q-Less", Vash mentions that the population of Brax known him as "The God of Lies".
Nitpick: During a discussion with the two Qs- where Janeway asks one of them to return Voyager to its correct time- the strap that extends under Q's shoe to hold his pant leg immobile is visible.
B'Elanna: This ship will not survive the formation of the cosmos!
Q: Without Q, there would have been no William T. Riker at all. And I would have lost at least a dozen really good opportunities to insult him over the years.
Q: My, my, now I guess we get to find out whether the pants... (looks at Janeway's posterior)... really fit.
Q: Forget Mark. I know how to show a girl a good time. How would you like a ticker-tape parade down Sri Lanka Boulevard? The captain that brought Voyager back, a celebrated hero. I never did anything like that for Jean-Luc. But I feel very close to you. I'm not sure why. Maybe it's because you have such authority, and yet manage to preserve your femininity so well.
Q: (to Janeway) A hearing? You would have me put his future into your delicate little hands? Oh, so touchably soft. What is your secret, dear?
Q: Have you heard about little me? Oh, do tell. Has Jean-Luc been whispering about me behind my back?
Tuvok: I am curious. Have the Q always had an absence of manners, or is it the result of some natural evolutionary process that comes with omnipotence?
Q: You've uncovered my one redeeming virtue. Am I blushing? I wish I could help you, Kathy. I just can't. We're dealing here with the most dangerous man in the Continuum. I didn't tell you this, but one of his self destructive stunts created a misunderstanding that ignited the hundred-year war between the Romulans and the Vulcans. No, he (Quinn) has to go back to his confinement. But I would like to make this easier for you. The Continuum is prepared to do you a little favor... if we approve of your ruling. Look out the window. Now you see it. (pauses as the planet Earth has appeared) Now you don't. (planet Earth disappears)
Q: Without Q, lsaac Newton would have died forgotten in a Liverpool debtor's prison a suspect in several prostitute murders.
Q: (to Janeway) Did anyone ever tell you you're angry when you're beautiful?
Q: (to B'Elanna) Just think of the honor of having your DNA spread from one corner of the universe to the other. Why, you could be the origin of the humanoid form.
Q: (to Chakotay) Oh, facial art. How very wilderness of you.
Quinn: I was the greatest threat the Continuum had ever known. They feared me so much they had to lock me away for eternity. And when they did that, they were saying that the individual's rights will be protected only so long as they don't conflict with the state. Nothing is so dangerous to a society. My life's work is complete. But they force immortality on me and when the do that they cheapen and denigrate my life and all life in the Continuum. All life. Captain, you're an explorer. What if you had nothing left to explore? Would you want to live forever under those circumstances? You want me to prove to you that I suffer in terms that you equate with pain or disease. Look at us. When life has become futile, meaningless, unendurable, it must be allowed to end. Can't you see, Captain? For us, the disease is immortality.
Quinn: I was even the scarecrow for a while.
Quinn: Because I'd never done it before.
Q: Oh, we've all done the scarecrow. Big deal.
Janeway: Based on my research, you have been many things, rude, interfering, inconsiderate, sadistic, a pest...
Q: You've made your point.
Janeway: Oh, and yes, you introduced us to the Borg, thank you very much. But one thing you have never been is a liar.
Q: I think you've uncovered my one redeeming virtue. Am I blushing?
Q: With your permission captain, I would like to call an expert on the Continuum to discuss the implications of the decision to be made.
Q: I call myself to the stand.
Q: (to the other Q) How did you get out, Q?
Janeway: We're responsible for that.
Q: Ah, well I guess that's what we get for having a woman in the captain's seat. You know, I was betting that Riker would get this command.
Quinn: When someone asks you about me, and they will, would you tell them I said - you know what, I've had 300 years to think of appropriate last words, I wanted something... memorable, you know, quotable - would you tell them I said "I die, not for myself, but for you."
Q: Say, is this a ship of the Valkyries, or have you human women finally done away with your men altogether?
The episode "Deathwish" is mentioned in the first season DVD retrospective "Voyager Time Capsule: Captain Janeway".
Kate Mulgrew states that this was one of the first episodes of the program in which the showrunners allowed her more creative freedom. She requested that she be allowed to be a more integral part of the creative process and Rick Berman told her "We'll back off from now on." Brief clips from this episode are also seen in this featurette.
Geordi LaForge was originally going to be the Starfleet Officer Q produced as a witness, but Levar Burton was sporting a clean-shaved head so the producers called in Jonathan Frakes at the last minute.
As of this episode, John de Lancie has played the same character (Q) on three different Star Trek series. The only other actors to do so are Armin Shimerman (Quark), Michael Ansara (Kang), Richard Poe (Gul Evek), Jonathan Frakes (Commander William T. Riker) and Marina Sirtis (Counsellor Deanna Troi).
Hemlock - Quinn's method of suicide
Hemlock is reportedly the poison used on Socrates to punish him for speaking out against the status quo - officially, corrupting the youth and disbelief in the gods of the state. According to his disciples Plato and Xenophon, contemporaries of Socrates, he could have recanted but declared death preferable.
