The Hobbit: The Desolation of Smaug2013

Thranduil:
[stares at Bilbo] I know you're there. Why do you linger in the shadows?

[Bilbo thinks he's been found out... ]

Tauriel:
[steps out from behind Bilbo] I was coming to report to you.

Thranduil:
I thought I ordered that nest to be destroyed not two moons past.

Tauriel:
We cleared the forest as ordered, my Lord, but more spiders keep coming up from the South. They are spawning in the ruins of Dol Guldur. If we could kill them at their source...

Thranduil:
That fortress lies beyond our borders. Keep our lands clear of those foul creatures. That is your task.

Tauriel:
And when we drive them off, what then? Will they not spread to other lands?

Thranduil:
Other lands are not my concern. The fortunes of the world will rise and fall, but here in this kingdom, we will endure. [Bilbo sneaks past him, Thranduil senses something and looks in Bilbo's direction but sees nothing]
