Londo: You're a security chief. Shouldn't you be out...securing something?
Michael Garibaldi: I am. I'm securing you.

Londo: Your ships are very impressive in the air, or in space, but at this moment, they are on the ground.
Morden: Right. They're on the ground. But they can sense an approaching ship miles away. So what're you gonna do, Mollari, huh? Blow up the island?
Londo: Actually...now that you mention it...
[he produces a small remote detonator]
Morden: NO!
[Londo blows up the island]

Lorien: I am the last, and...I was the first.
Susan Ivanova: I have to admit, I'm a little bit skeptical about that.
Lorien: Skepticism is the language of the mind. What does your heart tell you?
Ivanova: My heart and I don't speak anymore.
Lorien: So I've noticed.
. . .
Lorien: To live on as we have is to leave behind joy, and love, and companionship, because we know it to be transitory, of the moment. We know it will turn to ash. Only those whose lives are brief can imagine that love...is eternal. You should embrace that remarkable illusion. It may be the greatest gift your race has ever received.

Lorien: It's easy to find something worth dying for. Do you have anything worth living for?

Lyta Alexander: Byron, the Vorlons changed me. More than you could possibly know. I don't know what it'll do once you get past my barriers and I get past yours. It could burn you.
Byron: Then let it burn.

Lyta Alexander: Psi Cops are trained to make everyone nervous, but Bester can make even other Psi Cops nervous.
Zack: Hell, the man can make poison ivy nervous.

Lyta Alexander: Somewhere on Beta Colony there is an institution. In one room of the institution there is a man who spends his days and nights screaming at things that only he can see. Things we planted in his mind. They have to keep him in a straitjacket 24 hours a day or he'll claw his own eyes out just to make it stop. When it was over I transferred over to commercial work. I wanted out. The Corps took me in when I was just a few years old. They taught me what a telepath was, what we could do. Until that time I'd never been afraid of who we were. Until that day. When we did what we had to do...because no one else would.

Lyta Alexander: You can't change human nature, Byron.
Byron: Then there's not much point in living, is there? If you can't hope for something better, something nobler, at least something kinder?

Lyta: Pain... [whispered into a guard's ear; he then howls in agony and drops to the floor in a heap]

M'Ola: No one knows what is written in the stream [of Time] until the waters surround him.

Mack: (sees Mack cross himself) When did you get religious?
Bo: I'm not, just respect, that's all. Every time we get a red star born out there, somebody's life ends.

Mack: Hey, did you see that smile? I mean it was like the sun coming out from behind a cloud.
Bo: I did indeed. Suddenly, I think I understand Sheridan a lot better.
Mack: How do you mean?
Bo: Well, dead or alive, I'd climb my way out of hell and through ten miles of solid rock to see that smile again.

Mack: Tastes like chicken!

Major Krantz: What if we take you with us? Put you on trial?
Zathras: Zathras not of this time. You take, Zathras die. You leave, Zathras die. Either way, it is bad for Zathras.

Major Lianna Kemmer: I demand you open a channel to Earth at once!
Ivanova: I am a Lieutenant Commander in Earthforce, Major. I do not take demands. If you have a request, I'll consider it.
Maj. Kemmer: Very well, then. I request that you open a channel to Earthdome!
Ivanova: Request denied. Have a nice day.
