"I'd like to live just long enough to be there when they cut off your
 head and stick it on a pike as a warning to the next ten generations
 that some favors some with too high a price. I want to look up into
 your lifeless eyes and wave like this. Can you and your associates
 arrange that for me, Mr. Morden?"

"Diplomatic immunity only applies when the subject is charged with a
    crime. So far Mr. Morden hasn't been charged. We're holding him
    in...umm...protective custody."
'Protecting him from what?'
"I haven't decided yet."

"Be warned, once you know his secret, once you know what we have known
 for the last 3 years, you'll never sleep well again. Come Captain. The
 greatest nightmare of our time is waiting for you."

"There are beings in the universe billions of years older than either
 of our races. Once, long ago, they walked among the stars like giants,
 vast and timeless. They taught the younger races, explored beyond the
 rim, created great empires. But to all things there is an end. Slowly,
 over a million years, the First Ones went away. Some passed beyond the 
 stars, never to return. Some simply disappeared." 
        -- Delenn, "In the Shadow of Z'Ha'Dum"

"We have no other name for them. The Shadows were old when even the
 Ancients were young. They battled one another over and over across a
 million years. The last great war against the Shadows was ten thousand
 years ago. It was the last time the Ancients walked openly among us. The
 Shadows were only defeated, not destroyed. A thousand years ago, the
 Shadows returned to their places of power, rebuilt them, and began to
 stretch forth their hand. Before they could strike, they were defeated by
 an alliance of worlds, including the Minbari and the few remaining First
 Ones who had not yet passed beyond the Veil."

"When they had finished, the First Ones went away...all but one." 
'There's still one of them left. Where?'
"That is why Kosh cannot leave his encounter suit. He would be recognized."
'Recognized? By who?'
`Everyone.`
        -- Delenn, Sheridan, and Kosh, "In the Shadow of Z'Ha'Dum"
%%
"If yes was the answer, what was the question?"
'Have the Shadows returned to Z'ha'dum?'
        -- Sheridan and Delenn, "In the Shadow of Z'Ha'Dum"
%%
"Because right now, they do not know how much we know. The last time,
 the Shadows lost because they moved too quickly. Now, they are being
 careful, gathering their forces slowly. If you push Morden, sooner or
 later, he will tell you what happened. Then he will be killed. And you
 will be killed. The Shadows will move now, before we're ready for them."
        -- Delenn (to Sheridan), "In the Shadow of Z'Ha'Dum"
%%
"Aside from the Vorlons, we do not have the First Ones to help us this
 time. We are on our own! We will have only one chance to stop them, and
 if we fail, billions will die."
        -- Delenn (to Sheridan), "In the Shadow of Z'Ha'Dum"
%%
"Sooner or later, I'm going to Z'ha'dum, and I'm going to stop them." 
'If you go to Z'ha'dum, you will die.'
"Then I die, but I will not go down easily and I will not go down alone.
    You will teach me?"
'Yes.'
