Hartley could only stare down at the arm in his chest, sudden pain and shock overwhelming him. Oh. So this was how it ended. He really hadn't seen that coming. But it was fitting, in a way. That someone he loved would be the one to kill him. After all, it had always been the people he loved who hurt him the most. Why should this be any different?
It hurt. It hurt worse than anything he'd felt before. He felt his legs buckle, Eobard catching him as he fell. A pathetic part of him was just glad that he hadn't left, that he wasn't dying alone on the floor. He couldn't breathe past the pain and when he tried it was shuddering and wet. He could taste slick iron in his mouth and his vision was going hazy and dark. All he could think was that he deserved this for being stupid enough to think anyone could actually care about him.
He wanted to say something, but everything hurt too much and he was choking on blood and he didn't want to risk Eobard letting him go if he did. So he just shuddered in the other man's arms, sucking in agonizing breaths until he couldn't any more.
