A/N: Haylijah never happened in the series.
It was a beautiful day, when Elijah woke up in a spelled circle in a house. He'd been poisoned with the rosebush thorns the night before. The Hollow inside of Sofia, Marcel's girlfriend, wanted to become flesh by killing him. Because the thorns had Marcel's venom on them, it was lethal. All Elijah could do was wait for his siblings to save him. There wasn't much he could do. He was dying. He was trying to fight, but he knew it was only a matter of time.
Meanwhile, Klaus found out that something had happened, when Hayley told him she hadn't seen Elijah since the night before, so they worked together to figure out where he was. Freya tried a locator spell, but she found out that Elijah was cloaked by magic. She couldn't magically find him. That's when Klaus asked for Marcel's assistance in finding his brother.
Katherine, human, suddenly appeared someplace which she realized to be New Orleans, ascendant in hand and injured from her time in the prison world. She knew where she was, since Elijah was there, in pain and misery, laying in a spelled circle. She then saw someone there, obviously the one whom had caused this. That angered her and made her fear for his life all at the same time. Despite her injuries, she didn't let her weakness show.
"What the hell did you do to Elijah?" she said angrily, and magically pinned her against a wall. She then approached.
"If you aim to save his life, you can't. The thorns have Marcel's venom. Either way, he dies," she informed her, and laughed at that. "After that, I'll be unstoppable."
Katherine stopped her magic.
"No, you won't. I didn't come back to life to lose the love of my life. You won't win. The Mikaelsons and I are never defeated. You'll lose and go back to rock you crawled out from." She magically snapped the girl's neck. She then went to the circle and magically lifted the spell on the circle.
"Please, hold on, Elijah," she pleaded.
Elijah heard her and then blurrily saw her, not sure if she was real or not, as everything began to go black.
Once the spell was broken, she got him out of the circle and on his back. Then she knelt beside him.
"Stay with me, Elijah. Don't die on me."
She hovered her hands above him, starting a spell. She didn't know what she'd come back to life in the midst of, but she could still protect and save him. She could use magic to make sure no one could harm him and siphon the venom into herself. She'd rather die than for him to.
When Elijah woke up, he felt cured and saw a human and injured Katerina, letting him know that he hadn't imagined it. He realized that she was somehow human with magic. She'd saved his life.
He knelt by her, a hand on the side of her face, as she lay on her back with stab wounds and an opened artery in her thigh. He also saw that she had and was still losing a lot of blood.
"Katerina, can you hear me? Katerina. Open your eyes, Katerina," he called to her.
When she didn't wake up or move, he gently pulled her into his arms and got to his feet. He didn't know how she was human, so he didn't want to chance feeding her vampire blood. He had one way to save her life. He had to get Freya to heal her.
Stay with me, Katerina. I can't lose you. Keep fighting. Don't die on me, he thought, as he blurred home to get Freya to save her life. He couldn't lose her. Even after he broke up with her a few years ago, he still loved her. He always would. She was a piece of him and he was a piece of her. He could bare to lose her. He needed her to live. Besides, he hadn't looked out for her for 500 years, just to lose her now to a simple human death. They were meant to be there for each other forever. He knew now that he'd made a mistake by leaving. Because of him leaving, she'd somehow become human and was now dying, because he hadn't kept in contact to make sure she was okay. He had thought that she'd be okay on her own, just as always. He was wrong. Now, because of him, he may never have a chance with her again. He needed her to fight; stay strong. He couldn't bare it if she died.
