Luce 'Doc' Worth.
Doc Worth is made of damage. He is all sharp edges, protruding bones and stubble, bent cigarettes and bandages hiding self-given scars up and down his arms. He is 6"something and hardly over 130 pounds, digesting more pills and liquor than actual food. His Australian accent is harsh and distinctive, his trademark fur lined coat hiding his full stature, along with stereotypical slouching and bent knees.
He is always frightfully temperamental, but when he stands to his full height, insults and threats flying past chapped lips, he is a force to be reckoned with. Even the biggest of the back alley hack's enemies have backed down in that instance.
But Worth isn't all rotten. The man can have tender moments; namely when Hanna or someone else is bleeding out on his back table and his fingertips are slick with sweat and the crimson of another's life and that is when Worth is gentle. Or when no one else is around and Lamont is too drunk to drive and too drunk to remember to call him Worth or Doc and lets a slurred, 'Luce,' slip past with those nervous chuckles of his.
Worth is always pleasantly startled to realize how much emotion his own first name brings him in those instances. Rarely is Worth gentle, but even less so could he be considered emotional or sentimental. Doc isn't one for all those chick things; he'd rather punch a person in the face and start a fight and get off on it later than deal with all that sappy bullshit.
So, sue him if that makes him a bad guy, or inconsiderate, or a jackass, but that's just how he is. He's abrasive, but he (and everyone else, for that matter) wouldn't have it any other way.
