The last thing that Klaus hears before his heart stops is that panicked endearment, and it makes him want to hang on so badly. For so long, he was mostly unconcerned with whether or not he lived or died, to the point where he sort of leaned into it. He drove too fast, walked too close to traffic, drank too much and took too many drugs.

And now that he's in a good place, healthy and happy and with people that he loves, he gets taken out by a freak accident. It doesn't seem at all fair, but there isn't anything that he can do about it.

Or maybe that isn't true. While Luther sits there with Klaus's limp body in his arms, there's a part of him that's still fighting. Minutes pass as Luther holds him, blood dripping onto the steps, and Klaus fights his way back.

Eventually, his eyes snap open and he gasps, coughing up the blood in his through as his body shakes. He feels frozen to the bone and he whimpers as he takes in his surroundings. When his gaze lands on Luther's face, he knows that he's safe enough to go limp again, chest heaving as the hole in it starts to slowly knit itself back together.

"Holy shit," he pants out, eyes wide as he looks up at Luther's face. "I'm here, big guy. I'm here."
