Is that a tear? I never noticed it before. OMG, I think Thranduil is crying. This makes the confrontation with Thorin in Mirkwood even more meaningful. And this is so sad - Thranduil was in tears because his attempt to negotiate with Thorin for the return of his wife's jewels had failed! This is Thranduil realizing that the pride of the Durins will NEVER allow him to receive the necklace of his beloved late Queen.
