Babylon 5, Season 5: The Wheel of Fire

[Lochley and Zack go to the Zocalo to arrest Lyta on suspicion of terrorism. She displays how she has the entire Zocalo under her mental control.]

Lyta Alexander:
I'm tired of being pushed around, Captain. I do not choose to be arrested. I've done a lot for this place…and just once I think a little gratitude would be in order, don't you?

Elizabeth Lochley:
Lyta, don't force us to-

Lyta:
To what?

Lochley:
[gestures to Zack] Zack…

[He doesn't move. He, the deputies, and the rest of the crowd appear to be catatonic.]

Lochley:
Zack!

Lyta:
You cannot harm me. You cannot stop someone who's been touched by Vorlons.

[A PPG appears and lines up with the side of Lyta's head. Sheridan steps out of the crowd.]

John Sheridan:
You're not the only one that's been touched by the Vorlons. [gestures to the crowd] Let them go.

[Lyta stands resolute. Sheridan presses the gun into the side of her head.]

Sheridan:
Let 'em go or I'll blow the back of your skull off!

[Lyta relaxes her mental control, and the crowd begins moving again.]
