Delenn: 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.
Captain John Sheridan: If more of our so-called leaders would walk the same streets as the people who voted them in, live in the same buildings, eat the same food instead of hiding behind glass and steel and bodyguards, maybe we'd get better leadership and a little more concern for the future.
Zathras: Zathras is used to being beast of burden to other people's needs. Very sad life... probably have very sad death, but at least there is symmetry.
Ambassador Londo Mollari: Only an idiot would fight a war on two fronts. Only the heir to the throne of the Kingdom of Idiots would fight a war on twelve fronts.
Delenn: We are star stuff. We are the universe made manifest trying to figure itself out.
Citizen G'Kar: I believe that when we leave a place a part of it goes with us and part of us remains. Go anywhere in these halls, when it is quiet and just listen. After a while you will hear the echoes of all of our conversations, every thought and word we've exchanged. Long after we are gone, our voices will linger in these walls for as long as this place remains. But I will admit that the part of me that going will very much miss the part of you that is staying.
Captain John Sheridan: No surrender, no retreat.
Captain John Sheridan: Are you trying to cheer me up?
Susan Ivanova: No sir, wouldn't dream of it.
Captain John Sheridan: Good, I hate being cheered up.
Susan Ivanova: In that case we're all going to die slow, agonizing deaths.
Captain John Sheridan: Thank you, I feel so much better now.
Dr. Stephen Franklin: Doesn't anyone listen to one damn word I say?
Kosh Naranek: Understanding is a three-edged sword.
Commander Jeffrey David Sinclair: Mr. Garibaldi was right. He said this was going to be trouble.
Susan Ivanova: There's nothing more annoying than Mr. Garibaldi when he's right.
Ambassador Londo Mollari: Ah, arrogance and stupidity all in the same package. How efficient of you.
Susan Ivanova: Ambassador, do you really want to know what's going on down there?
Ambassador Londo Mollari: Yes, absolutely.
Susan Ivanova: Boom. Boom boom boom. Boom boom. Boom! Have a nice day.
G'Kar: No dictator, no invader, can hold an imprisoned population by force of arms forever. There is no greater power in the universe than the need for freedom. Against that power, governments and tyrants and armies cannot stand. The Centauri learned this lesson once. We will teach it to them again. Though it take a thousand years, we will be free.
Lt. Corwin: Do we trust no-one then?
Cmdr. Susan Ivanova: No, trust Ivanova, trust yourself, anybody else, shoot'em.
Captain John Sheridan: Delenn, I have been working up a good mad all day and I am not about to let you ruin it by agreeing with me.
Susan Ivanova: Vakar Ashok, our gun arrays are now fixed on your ship and will fire the instant you come into range. You will find their power quite impressive... for a few seconds.
Sinclair: They say God works in mysterious ways.
Michael Garibaldi: Maybe so, but He's a con-man compared to the Vorlon.
Ambassador Londo Mollari: But this - this, this, this is like being nibbled to death by... what are those Earth creatures called? Feathers, long bill, webbed feet... go 'quack'.
Ambassador Vir Cotto: Cats.
Ambassador Londo Mollari: Cats. Being nibbled to death by cats.
Na'Toth: The Narn regime has accomplished many things in its glorious past, but bodysnatching isn't one of them.
Chosen answer: She was promoted to Captain and thus had to leave Babylon 5, becoming a captain on a new Warlock class ship. Later on she retires/quits and becomes the top Ranger on Minbar.
