[Sheridan complains to a bemused Franklin about the "bean counters" trying to charge him rent for his quarters.]
John Sheridan: They nibble a little bit here, a little bit there--next thing you know, you're not even in charge of your own command anymore!
Stephen Franklin: No taxation without representation. Give me liberty or give me death!
Sheridan: Abso-fraggin'-lutely!

[Sheridan has been invited to dinner by Delenn.]
Sheridan: One day they're shooting at you, the next day they're taking you out to dinner. Ha! What a universe!

[Sheridan is inviting Delenn to dinner in his quarters]
John Sheridan: You know, every time that I have seen you lately, we've been in the middle of a crisis! A revolution! I mean, this is the first time in months that it's been this quiet! It won't last. It never does. But as long as it's here...I'd like to see you tonight.
Delenn: Are you not seeing me now? I would assume that you see me every time we meet. Unless I have become translucent, or insubstantial, and no one has thought to inform me until now.
Sheridan: Then let me say I'd like to see you in a different light. Candlelight, for instance. Over dinner?
Delenn: Tonight?
Sheridan: Tomorrow we may be involved in another crisis, another battle! This may be the last chance we'll get for a while. You know, back home we have a saying. "Eat, drink and be merry, for tomorrow we die!"
Delenn: Humans can be a very depressing people.
Sheridan: Only if we get turned down for dinner.
Delenn: Well, we cannot have that, now can we?

[Sheridan is speaking with the Drazi ambassador about White Star ships on the borders of Centauri and Narn space.]
Sheridan: I can't confirm that.
Drazi Ambassador: But you're not denying it either.
Sheridan: But not denying it doesn't make it true any more than not confirming it makes it false. - Are you with me so far?
Drazi Ambassador: I'm not sure.
Sheridan: Ambassador, there are so many things in the universe that are and so many things that aren't. If I were to take the time to deny all the things that aren't, we'd be here for centuries, wouldn't we?

[Sheridan is told that the Joint Chiefs have ordered him to apologize to the Centauri.]
John Sheridan: I suppose this...apology is already written?
Mr. Welles: No need. You can phrase the apology any way you see fit. As with everything else, it's the thought that counts.

[Sheridan pounds on the Nightwatch member who knifed Delenn.]
Sheridan: No more! No more of you! No more Nightwatch, no more hostages, no more lies! Not on my station! Not on my watch! No more!
[one last big punch]
Sheridan: No more!

[Sheridan practices his apology to the Centauri government before a mirror.]
Sheridan: I apologize. I'm...sorry. [sighs] I'm sorry we had to defend ourselves against an unwarranted attack. I'm sorry that your crew was stupid enough to fire on a station filled with a quarter million civilians, including your own people. And I'm sorry I waited as long as I did before I blew them all straight to hell! [pauses] As with everything else, it's the thought that counts.

[Sheridan praises Ivanova for her telecasts during the Shadow war.]
John Sheridan: You have a face people trust.
Susan Ivanova: I'd rather have a face people fear.
Sheridan: That too.

[Sheridan proposes to Delenn]
John Sheridan: I, um...I wanted you to have this. I got it down in the Zocalo. It's not exactly what I had in mind, but, um...It's temporary until I can get you a real engagement ring. Um, it's an Earth custom. See, you give someone you love an engagement ring as kind of down payment for another ring. The kind you exchange when you get married. I don't know when we will be able to get around to that part of it. We may not survive the next two weeks, but I wanted you to have this and to know that whatever time I have left, I want to spend it with you.

[Sheridan sends Ivanova to resolve a problem, then sighs to himself.]
John Sheridan: Ah, it's good to be the captain.

[Sheridan talks to his father before the imminent battle.]
David Sheridan: Son...I follow the news. Well, I did until ISN went black! I see what's going on. Your mother doesn't like to think about it. You know how she is. John, I can't imagine the kind of decisions that are going through your mind right now. I'm sure they're not easy. The important ones never are. But when push comes to shove, you've always done the right thing. What was the first lession I ever taught you?
John Sheridan: Never start a fight, but always finish it.

[Sheridan tries to encourage an imprisoned Drazi.]
John Sheridan: You just have to say "no, I won't" one more time than they can say "yes, you will".

[Sheridan's "good luck speech" upon taking command of Babylon 5]
John Sheridan: When I was 21, I visited Tibet. I went to see the new Dalai Lama. Uh, you do that sort of thing when you're 21 and the son of a diplomatic envoy. We had a simple dinner. Rice, raisins, carrots--steamed, not boiled--and green tea. When it was over, he looked at me and said, "Do you understand?" I said no, I didn't. "Good beginning," he said. "You'll be even better when you begin to understand what you do not understand." After reading some of your reports, I begin to understand what I don't understand about Babylon 5. But I couldn't wish for a more capable and skilled group of people to learn from. It was an early Earth President, Abraham Lincoln, who best described our current situation. He said...
[he gets interrupted by a security alarm]
. . .
Sheridan: [delivering the rest of his speech to an empty C&C] It was an early Earth president, Abraham Lincoln, who best described our situation. "The dogmas of the quiet past are inadequate to the stormy present. The occasion is piled high with difficulty, and we must rise to the occasion. We cannot escape history. We will be remembered in spite of ourselves. The fiery trial though which we pass will light us down in honor or dishonor to the last generation. We shall nobly save or meanly lose our last, best hope of Earth." [He looks around with a satisfied smile.] Five minutes to spare.

[Sheridan's liberation fleet finally confronts Earth itself.]
John Sheridan: This is Captain John Sheridan. We are here on the authority of a multi-planetary force, that can no longer stand by and watch one of their greatest allies falling into darkness and despair. We are here on behalf of the thousands of civilians murdered under orders from the current administration, who have no one else to speak for them, and on behalf of the EarthForce units that have joined us to oppose the tyranny that has darkened Earth, ever since President Santiago was assassinated three years ago. We are here to place President Clark under arrest, to disband Nightwatch, and return our government to the hands of her people. We know that many in the government have wanted to act, but have been intimidated by threats of retaliation against your families, your friends. You are not alone anymore. We call upon you to rise up and do what's right! We have drawn their forces away from Earth and disabled them. The time to act is now! This is not the voice of treason. These are your sons, your daughters, whose loyalties have never wavered, whose beliefs in this alliance has [sic] forced us to take extraordinary means! For justice, for peace, for the future...we have come home!

[Sheridan's telepath gambit has disabled General Lefcourt's ship, along with the rest of the loyalist fleet.]
General Lefcourt: Engineering, this is General Lefcourt. In case you didn't notice, the enemy just pulled our shorts up over our head and tied them into a knot. You will get the ship under control ASAP, or I will come down there and skin the hide off every last one of you.
