Summary: She would always be his weakness, he knew that. If he gave her his blood, saved her, she'd still be in danger. And that's why he couldn't save her.

"Please, Klaus," her voice whispered hoarsely. He turned his eyes to her form, looking at how her skin was greying, the bite mark oozing on her shoulder. He tore his eyes away quickly. He couldn't stand to see her like this, but this time, he knew it was necessary.

They'd been happy together, at least for a while. That was until his enemies caught wind of her. Since then, the attacks had been non-stop. They tried to kidnap her, abuse her, kill her all in an attempt to get to him. And until now, they'd always failed, he'd made sure of that. But this time the wolves had managed to do what others had failed to do so. They got to her.

"Klaus..." her voice rasped out. He refused to look though, if he looked then he'd break and save her, and if he was being honest, he couldn't do it.

As long as he lived, they'd never stop. She would be in constant danger, every second he'd be wondering if it'd be her last. He'd once considered compelling her and sending her away, but that wouldn't stop them. She might not remember him, but he'd never forget her, and they'd always knows what she means to him.

"Klaus..." Her voice was significantly weaker now. He still couldn't look though, not now.

She would always be his weakness, he knew that. If he gave her his blood, saved her, she'd still be in danger. And that's why he couldn't save her.

"I'm sorry, love. This is for the best."

Getting up, he walked out the room. He couldn't be with her like this, especially in her final moments. Besides, blood needed to be spilt.
