That's always the best and hardest part of emotionally charged scenes, conveying intense emotion without overplaying it. Good luck with it!

Given Thranduil's canon tendency for leaves/branches/flowers over Noldor-style metal jewellery/crowns, I wonder if he might even wear them, in a declaration of solidarity with his son. Baby fangs as adornment. (they are kind of badass. sharp fierce little baby elf fangs~~)
