Babylon 5, Season 5: The Wheel of Fire

[after a Ranger trainee has been attacked, his teacher declares Mora'dum-the application of terror]

Delenn:
Captain, this is not about revenge.

Elizabeth Lochley:
[sarcastically] Oh? Then what is this about?

Delenn:
Terror.

. . .

Lochley:
So, what kind of terror are we talking about here, Delenn?

Delenn:
The kind that cripples…the kind that destroys. Not from without, but from within. As soon as he can stand, whether he is fully healed or not, Tennier will prepare to face his terror. Those who harmed him now have power over him. He must take back that power or he will never be whole again. We will go with him, and bring him to the point of his terror. And then, he will face it.

Lochley:
But if he isn't fully healed, he could die in the effort.

Delenn:
As Anla'shok, we choose to do that which frightens us, knowing that there are no guarantees. He may lose; we cannot help him.

Lochley:
Then he will stand alone.

Delenn:
At the end, Captain, we all stand alone.
