Babylon 5, Season 2: The Coming of Shadows

[Draal tells Delenn and Sheridan about what he's discovered using the Great Machine.]

Draal:
Since taking up residence in the heart of this machine, I have explored its secrets, learned, and discovered that I can look into distant worlds, see and hear things you cannot begin to imagine! Along the way, I've learned some things about you, Captain! The loss of your wife-I know Delenn has told you about the coming darkness. And lately I've learned about your role in, shall we say, a "conspiracy of light" aimed at your own government?

John Sheridan:
I don't know what you're talking about.

Draal:
Yes, you do! Please, Captain, don't worry. Your secret is safe with me. They would have to dig down three miles into the surface of this planet to learn what I know, and no one who tried would survive the attempt! And now I have seen enough! I said a year ago that this place was to be left alone until the time was right. That time has arrived. Now that I know the full capabilities of this place, I am prepared to place them at your disposal!

Sheridan:
Are you proposing an alliance?

Draal:
One of the first! There will be more to come. This has been a hard and trying year for you, Captain Sheridan. It might be helpful for you to know that you are not alone, and that in the long, twilight struggle which lies ahead of us, there is the possibility of hope.
