I've heard a fandom rumor going around that among the white gems Thranduil mentions in DOS is a necklace that belonged to his (deceased?) wife. And this gif makes me think PJ might actually go that route. Look at Thranduil's face as he says this. He looks like he's going to cry! Would he cry this much over white gems? This makes me wonder if Thranduil wants jewelry that once belonged to the Queen of Mirkwood. This would explain the tears, especially if she were dead.
