Thorin Oakenshield: [Staring at the space on the throne where the Arkenstone would be] It is here in these halls.
Dwalin: We have searched and searched everywhere.
Balin: We all want to see the Arkenstone returned.
Thorin Oakenshield: [seething] And yet it's still not found!
Balin: Do you doubt the loyalty of any of us? The Arkenstone is the birthright of our people.
Thorin Oakenshield: It is the King's Jewel. AM I NOT THE KING? Know this. If anyone should find the Arkenstone and withhold it from me, I will be avenged.
