Delenn: We are all slaves to our histories. If there is to be a...bright future, we must learn to break those chains.

Delenn: What are you doing here?
Kosh: Creating the future.
<Kosh stares into the area before them and a hologram flickers into view>
Hologram Dukhat: If you are seeing this message, it is because I am dead. I entrust this message to the Vorlons to give it to the right person at the right time. They have come to us in secret and they say that this time, we will need allies. A particular race so far unknown to us, called humans. It is their hope that we find these humans and bring them into the battle on our side. The servants of the Shadows are gathering at Z'ha'dum. Their masters can not be far behind. Finish what I have started. Finish it.

Delenn: What if the station falls?
Sheridan: Then, as you said to me once, "I'll see you again in the place where no shadows fall."

Dr. Stephen Franklin: I'm a doctor! My duty is to heal!
Gen. Franklin: Then heal humans! Stephen, I know you're fascinated by these alien creatures, but they're a threat to humanity. And they always will be. Help your own kind!
Dr. Franklin: Life is life, whether it's wrapped in skin, scales, or feathers! Now if you respected these beings instead of constantly trying to murder them, you'd appreciate that!

Draal: [addressing the command staff] Good afternoon, everyone! Captain, Delenn tells me that you're going to try contacting the First Ones. It is a magnificent idea--a daring and splendid idea! In doing so, you will see things no human has ever seen before! It will be...fun! Assuming you're not vaporized, dissected, or otherwise killed in an assortment of supremely horrible and painful ways! Exciting, isn't it?

Draal: I asked for Captain Sheridan!
Ivanova: Um...He's busy.
Draal: I don't like surprises!
Ivanova: Really? Love 'em, myself. To me, everything's a surprise! You're a surprise. This place is a surprise. You see this? [She holds up a finger.] Paper cut. Hurts like hell! Anybody else would be upset, but to me, it's just one more wonderful surprise! I mean, I even surprise myself sometimes! So I guess there's nothing wrong with me surprising you. Right?
[Draal's angry facade cracks, and he bursts out laughing.]
Draal: I like you! You're trouble!
Ivanova: [laughing in relief] Well, thank you! That's the nicest thing anybody's said about me in days!

Draal: Quickly, what is the third principle of sentient life?
[Delenn turns around and sees Draal.]
Delenn: Draal!
Draal: Incorrect answer! The third principle of sentient life is the capacity for self-sacrifice: the conscious ability to override evolution and self-preservation for a cause, a friend, a loved one. It has been too long, Delenn. You have forgotten your training. Soon you will have forgotten all about your old friend Draal.
Delenn: Not if I live to be a thousand and one.

Drazi Ambassador: Every great fall begins with a single mistake.

Dulann: His concern was for us, not for himself. I know. I saw it in his soul.

Earth President Susanna Luchenko: Well, Captain, you caused quite a stir. Half of EarthForce wants to give you a kiss on the cheek and the Medal of Honor. The other half wants you taken out and shot. As a politician you learn how to compromise. Which by all right means I should give you the Medal of Honor, then have you shot. I confess the idea had a certain appeal when I mentioned it to the Joint Chiefs two hours ago. [...] The bitch of it is that you probably did the right thing. But you did it in the wrong way, in the inconvenient way. Now you have to pay the penalty for that. I know it stinks, but that's the way it is.

Earth President: This is...This is the president. I have just been informed that our midrange military bases at Beta Colony and Proxima 3 have fallen to the Minbari advance. We have lost contact with Io and must conclude that they too have fallen to an advanced force. Our military intelligence believes that Minbari intend to bypass Mars and hit Earth directly, and the attack may come at any time. We have continued to broadcast our surrender and a plea for mercy, and they have not responded. We therefore can only conclude that we stand at the twilight of the Human race. In order to buy more time for our evacuation transports to leave Earth, we ask for support of every ship capable of fighting, to take part in a defense of our homeworld. We will not lie to you. We do not believe survival is a possibility. We believe that anyone who joins this battle, will never come home again. But for every ten minutes we can delay the military advance, several hundred more civilians may have a chance to escape to neutral territory. Though Earth may fall, the Human race must have a chance to continue elsewhere. No greater sacrifice has ever been asked of a people, but I ask you now, to step forward one last time�one last battle to hold the line against the night!... May God...go with you all.

Edgars: Do you know how the ancient Greeks defined happiness?
Garibaldi: Not off-hand, but I'd be willing to bet it involved three goats and a jug of wine.
Edgars: "Happiness", they said, was "the exercise of vital powers along lines of excellence, in a life affording them scope".

Elizabeth Lochley: As long as you're running an efficient operation and aren't looking for trouble, you are doing just fine.
David Corwin: That's what I'm trying to tell you. Around here we don't have to go looking for trouble. On B5, trouble comes looking for us.

Elizabeth Lochley: Dr. Wolfgang Pauli was a physicist during the late 20th century. Whenever he stepped inside the physics lab, something would go wrong or break down, usually a very expensive piece of equipment. Became kind of a joke with the other doctors, who called it the Pauli effect. According to the story, one day an extremely sensitive and expensive piece of equipment exploded, but he wasn't in the room. So for the first time, they had some proof that the Pauli effect wasn't real. Until they found out that at the exact moment the equipment exploded, he was on a train passing by right in front of the place.

Elizabeth Lochley: You're asking the impossible.
John Sheridan: Then I am asking the right person.
