Thranduil was not surprised when he heard that a human had been found in the forest, they had come here more than once, looking for adventure or the elves themselves or who knows what else. This time was different.
This time, a person was standing in front of him, barely alive, in a terrible condition, it even looked bad, dirty, with a lot of wounds and somehow still alive.
You were like dead, but somehow alive. You didn't say anything, you didn't beg, it seems you didn't care about everything. His elves said that the bag on your head had torn from behind the branches and so you had air to live on.
And he took pity on you, probably for the first time, the first time when he got nothing in return, and Legolas asked to spare your life.
His elves healed you, restored your weak body, you even found it hard to believe you survived at first. You've heard of elves before, but you've never seen them, and you didn't even know that your body would be dumped here.
Thranduil entered the temporary chamber where you were resting, part of your body bandaged and your powers not yet fully restored. He could tell it was like the effects of torture.
You were lying on the bed when he walked in, he had to know something about you because you were probably the first person in here who was still alive or not a prisoner.
"Can you talk? I need an explanation."
