The Hobbit: The Desolation of Smaug2013

Thranduil:
Some may imagine that a noble quest is at hand - a quest to reclaim a homeland and slay a dragon. I, myself, suspect a more prosaic motive: attempted burglary, or something of that ilk. You have found a way in. You seek that which would bestow upon you the right to rule. The King's Jewel. The Arkenstone. It is precious to you beyond measure... I understand that. There are gems in the mountain that I, too, desire. White gems of pure starlight. I offer you my help.

Thorin Oakenshield:
I am listening.

Thranduil:
I will let you go if you but return what is mine.

Thorin Oakenshield:
A favour for a favour...?

Thranduil:
You have my word, one King to another.

Thorin Oakenshield:
I would not trust Thranduil, the great King, to honor his word should the end of all days be upon us! You, who lack all honor! I have seen how you treat your friends. We came to you once, starving, homeless, seeking your help, but you turned your back. You turned away from the suffering of my people and the inferno that destroyed us! Imrid amrâd ursul!

Thranduil:
Do not talk to me of dragon fire! I know its wrath and ruin! I have faced the great serpents of the north... I warned your grandfather of what his greed would summon, but he would not listen. You are just like him. Stay here, if you will, and rot. A hundred years is a mere blink in the life of an elf. I'm patient. I can wait.
