Finarfin does not do touch. Always he tenses and his eyes flash and his heart beats faster, whether it's Ingwion squeezing his shoulder in jest, or a healer tending to a dislocated bone.
Not that people often touch him. Ingwion is rarely there, and healers must be quick to see to everyone. His station puts him above others, and his character (mean, snipy, cold, scared) tends to ward everyone else off.
He does not do touch. Does not even consider it: he is a king, and it is a lonely part to play, in a kingdom ruined and people wounded; he is a warrior, a leader who has to be sharp, has to be strong.
At nights the surety with which he holds onto those convictions about himself falter. His tent is dark and empty and when he does not sleep, he works; when he does not work, he is too exhausted to stay awake. But sometimes he lies between the furs in the silence of the night, and all the loneliness and fear seizes him; sometimes he has to count his breath, and hug himself with both hands, and whisper, it's okay, it's okay, you will be fine just to stay sane. He wants, so desperately wants to not be alone; tries so hard not to cry when he sees an eternity of nights like this before him.
Sometimes people touch him, and he clings to it. Sometimes Ingwion bumps his shoulder and Finarfin's lips quirk in a smile. Sometimes Eönwë squeezes his arm to check for injuries after the battle, and Finarfin remembers it when alone, brushes the same spot to feel it. He feels pathetic for it, sometimes: fighting so desperately to retain something the others give away as freely as breath.
He never says any of it, of course. Does not think if others notice: it does not matter. After all, it is not his biggest concern, not when arrows rain on him every day, when with each battle a sword lands a bit closer to his heart, an arrow whistles a bit closer to his throat.
The healer bandages his shoulder. He closes his eyes, and tries not to think how the touch makes him sick and starved at the same time.
