CHAPEL: 
Don’t you see, Roger? Everything you’ve done has proved it isn’t you.
…
SPOCK: Captain, are you all right? Nurse? Where’s Doctor Korby?
KIRK: Doctor Korby was never here.
PICARD: what is it you want, Q?
Q: Your compassion. All right, Sanctuary on this ship, dreary as it may sound to both of us.
PICARD: Return that moon to its orbit.
Q: I have no powers. Q the ordinary.
PICARD: Q the liar. Q the misanthrope.
Q: Q the miserable. Q the desperate. What must I do to convince you people?
WORF: :mad: Die.
Q: Oh, very clever, Worf. Eat any good books lately?
…
Q: All right, everyone, this is what we’re going to be doing.
LAFORGE: Q, everybody already knows what they’re going to do, except for you, Now here’s what I need.
Q: La Forge, obviously my knowledge and experience far exceed yours by about a billion times. So, if you’ll just step aside gracefully.
LAFORGE: Q, your experience will be most valuable to me if you can manually control the field integrity.
Q: Don’t be foolish. That would be a waste of my talents.
LAFORGE: Q, get to the controls or get the hell out of here. Data, you’re my liaison to the Bridge. I’ll need you with me.
Q: Who does he think he is, giving me orders?
DATA: :dubious: Geordi thinks he is in command here, and he is correct. 
TROI: Data, are you alright?
DATA: The arrow impacted just above my sixth intercostal support, penetrating my secondary subprocessor. Fortunately, none of my biofunctions seem affected. Do not be concerned, Counsellor. I believe your aim is improving.
(Data is lying on the floor as Geordi, Picard, Kareen and Pulaski enter)
LAFORGE: Data. Data, can you hear me?
(Data opens his eyes)
DATA: Geordi.
LAFORGE: Yeah.
DATA: May I ask a question?
LAFORGE: I think you just did.
DATA: Quite correct. Then may I ask another question after this one?
LAFORGE: You can ask me anything you want.
DATA: 
Why am I lying on the floor in this undignified position with the four of you standing over me, displaying expressions of concern?
PICARD:*** I’ve heard more than enough. You’re you again. ***
SULU: The captain really must be going mad if he thinks he can get away with an execution.
CHEKOV: Captain Kirk wouldn’t order an execution even if he were going mad. That cannot be the captain.
Have no fear, Sargon’s here.
Someone once told me that time was a predator that stalked us all our lives. But I rather believe that time is a companion who goes with us on the journey and reminds us to cherish every moment because they’ll never come again. What we leave behind is not as important as how we’ve lived.
GUINAN: I knew it was you.
Q: You! Picard, if you had half the sense you pretend to have, you would get her off your ship immediately. And if you like, I’d be more than pleased to expedite her departure…
Q: … This creature is not what she appears to be. She’s an imp, and where she goes, trouble always follows.
PICARD: You’re speaking of yourself, Q, not Guinan.
GUINAN: You just do. Do you remember the first time we met?
PICARD: Of course.
GUINAN: Don’t be so sure. I just mean, if you don’t go on this mission, we’ll never meet.
I’d be delighted to offer any advice I have on understanding women. When I have some, I’ll let you know.
GUINAN: It must be terribly frightening for you, to be totally defenceless after all of those centuries being omnipotent.
Q: I’m warning you. I still have friends in high places.
GUINAN: Frightening one race after the other, teasing them like frightened animals, and you enjoying every moment of your victim’s fears.
Q: From now on I’ll do missionary work, okay?
A question! Since before your sun burned hot in space and before your race was born, I have awaited a question.
DATA: The captain and many of the crew are not yet convinced [Q] is truly human.
GUINAN: Really?
grabs a fork
stabs Q’s hand
Q: AHHHHH!
GUINAN: Seems human enough to me.
Simple. Change the gravitational constant of the universe.
The line must be drawn here! This far, no farther!
Mr. Spock: Astronomical, Captain.
Death to Zeons!
For the world is hollow…and I have touched the sky!
Not everyone keeps their genitals in the same place.
