“I know how I feel. I’m not afraid”
“i love the look on her face as she reacts to him speaking khuzdul at her and the look on his face as it smoothly transitions from ‘processing her words’ confusion to ‘absolute understanding’ happiness it’s so beautiful and wonderful” (omnicom)
Speaking in khuzdul is a big deal. It’s an element of dwarvish culture that is secret. It’s literally referred to as the secret language of the dwarves. And speaking it to an outsider, to an elf no less, is so huge on its own.
