Babylon 5, Season 4: No Surrender, No Retreat

[G'Kar has been taken prisoner by the Centauri, tortured, and now languishes in an underground cell. Londo Mollari steps in to visit him, asking for his help in removing the emperor. Just before he leaves, G'Kar rebuts.]

G'Kar:
You didn't ask the price…for my cooperation.

Londo Mollari:
[incredulous] You are not exactly in a position to bargain, G'Kar.

G'Kar:
Neither are you. You want my help…for the sake of your people. I will give it…for the sake of my own. If I remove the monster from your throne, you will remove the monster…from my world. Leave Narn! Set my world free! Promise me this, and I will do as you ask.

[Mollari thinks about this for a moment, then realizes he has no choice and agrees.]

Mollari:
You have my word.

[He is let out of the cell by the guard, allowing the bright light to stream in from outside. G'Kar lies back against the wall of his cell, basking in the glow, joyful tears in his eyes.]
