The last thing that Klaus sees is Lan Wangji kneeling over him. Perhaps not the person that he expected to be there with him at the end, but at least it's a familiar face. Mostly familiar, anyway. He's never seen it looks quite so vibrant with emotion.

Klaus opens his mouth to try and speak, but there's too much blood. Whatever it was that did this must have blown through his lung, because it's all blood and no breath. He can't take in any air, and in the end he isn't sure what kills him in the end, the trauma or the choking.

He lifts his hand and puts it over Lan Wangji's on his chest, because Klaus knows that he's trying to save him, but it's too late. Klaus looks at him for another moment and then goes limp, hand falling to the pavement as his eyes point towards the sky, empty and unfocused.
