Princess.

It had been a term of scorn. Endearment. A nickname and she'd never paid much mind to it. Not once. She probably didn't even remember that he'd called her that up on the ARC. He'd been on janitorial duty and she was the daughter of the great Dr. Griffin. So of course she didn't remember.

But, he'd called her that for so long.

When they landed on this death trap of a planet he blamed her for his sister's being damned here. He didn't mean it though, not really. It wasn't her fault. Like her father, she tried to warn everyone of the oxygen depletion. For that, she ended up down here too. But, he'd still been so angry with her. That was O's life.

This put him at war with himself because he cared about her. Her natural leading ability rivaled his own. That was why he listened, why he heard her. She didn't know, but they were so much of the same person.

And then there was the Spacewalker. He came in and for some reason that spurned a deep fire in him too. The guy was reckless and carefree and she liked that. And then she killed him. Tears streaked her face as she plunged the sharp knife into his side. His eyes bulged and then deadened and for a second time froze, only for a second, right before his last breath escaped him.

Soon enough, she disappeared. Everyone disappeared. The mountain took them and he didn't know what to do. So he did what he knew he could do. He went in after her. Her and all of them. Clarke was brought to a decision. A terrible one and she couldn't make it by herself. He wouldn't let her make it on her own. She would never be alone. Not after all of the loves of her life left her, betrayed her or…died. He would remain for she would need somebody to lean on and he could handle that. She was his princess. His hand covered hers and helped her push that switch. The one that would kill so many.

And then she was gone. Disappeared. Dead.

Not dead. The Commander. There Clarke oddly found solace. Such a dark place to find it. The guilt was drowning her still. It was drowning both of them but she didn't bother to come back to him. That was okay. She needed time. They all did.

Suddenly nobody was safe. Technology had never been so dangerous and yet Clarke couldn't help but play with it and put her life in Murphy's hands. Why? Didn't she trust him?

He was there though even though she had her problems. Even when she pointed a gun at him. But, he knew. She would never kill him. She couldn't. He knew it was because she knew just as well as him. It was the two of them. As much as they fought, struggled and cared. They were there for one another.

And she never even knew. Just like every prince, he needed his princess.

Even more, he knew that if she ever drew her last breath it would his last as well. Deep down, she knew too. One could not survive without the other even if she never came to terms with how much he loved her. He could be friends with her for the rest of his life. But he couldn't live without her. He wouldn't.

She was his soulmate.
