As Gilliam well understood, you need to maintain a proper balance of anxiety and fear and chaos and horror in order to keep life going. And if we don't have that, we need to invent it.

Tanya: "Look at all those beds... Where is everybody?"
Edgar: "Looks like they were in a hurry."

Curtis: "What? What did he say?"
Yona: "He said you guys are fucked. You stupid tail sectioners. There's a tunnel right after Yekaterina Bridge."
Curtis: "A tunnel?"
Yona: "Mm-hm. A fucking long one."

Curtis: "I'm gonna make this real simple for you. You help us, you get your drug. If not, we put you back where we found you. What'll it be, asshole?"
