Gotham, Season 4

Jim Gordon:
You say this knife is important to your country. Please explain.

Ra's al-Ghul:
There is an ancient story amongst my people of a man who could not die. In his time, he committed terrible acts, raised a great kingdom, and then vanished.

Jim Gordon:
What happened to him?

Ra's al-Ghul:
If the legend is to be believed, he walked away from his throne, vowing that one day he would return and complete his destiny. But that would require a particular knife.

Jim Gordon:
This knife.

Ra's al-Ghul:
A story, as I said. But to my people, very meaningful. I hope that satisfies your curiosity.

Jim Gordon:
Some. But you see, Minister, my chief concern is that there's a boy, the grandson of the curator. He's being hunted. Now, perhaps that's because of the knife. Or, perhaps, the killer thinks he saw something.

Ra's al-Ghul:
Did he?

Jim Gordon:
No.

Ra's al-Ghul:
Well, then, he's safe.

Jim Gordon:
Yes, but, you see, I would have to know that for certain before I would do anything that might effect the case... such as release the knife.

Ra's al-Ghul:
[cold] May I see the knife, Detective? It would so put my mind at ease.
