Sienna: You lied to me when you asked for my help.
Langdon: Well, technically, I withheld.
Bertrand Zobrist: There have been five... major... extinctions... in the Earth's history... and unless we take bold, immediate action... the sixth extinction... will be our own.
Sienna Brooks: It's what nature demands. The problem won't just be slowed down, it will be solved. Permanently.
Sienna Brooks: You called him a murderer. A psychopath.
Robert Langdon: What?
Sienna Brooks: But history will call us saviors.
Robert Langdon: Oh, my god. Oh, my god.
Sienna Brooks: I'm not afraid to act, Robert. But doing nothing terrifies me.
Robert Langdon: The path and-and the pointer, he left that all for you. Zobrist. You knew him?
Sienna Brooks: Knew him? I loved him. You're wearing his suit.
Professor (Istanbul): For what did Zobrist die?
Sienna Brooks: That others may live. I've come very far to make sure nothing interferes. The delivery system we designed will discharge the viral agent by midnight tonight. But there are others who are on their way to stop it. I need to find it before they do and trigger an explosion to ensure its release.
Professor (Istanbul): How do we help?
Robert Langdon: Zobrist is dead, but if his plague is real, then this map, it's a trail he has left so someone can find it.
Sienna Brooks: Who?
Robert Langdon: Well, someone who believes the same as he does.
Sienna Brooks: And that's why you have it?
Robert Langdon: Well, I don't remember ever meeting Zobrist.
Harry Sims: Young people are disappointing. I find they become tolerable around 35.
