The Argo II hovered over somewhere in the south of Italy, far away from Rome but still the sight haunted Nico.

He had just watched them fall, helpless. He'd watched as Percy let go of the ledge and plummeted into the depths of Tartarus, clinging onto Annabeth as he did so. It was his fault, he should have cut the silk before it was too late, he should have realised... That Annabeth would be the one to pay for his mistake. He could still hear it, the monster.

Rise young Demigod, but know that as you wake another shall slip. Down, down, down, she goes.

Then he had woken up in that horrible warehouse, with Percy, Jason and Piper fighting for his life.

"If only they knew what my life would cost," He said aloud.

He heard footsteps coming up behind him, Hazel. She was the only one who knew who was really to blame for Percy and Annabeth...

"Nico," She started, exasperated, "You can't blame yourself. It isn't your fault! For all you know the monster was a hallucination."

She put a hand on his shoulder.

"Yeah, yeah, you're probably right," He said, turning to give her a reassuring smile.

Hazel looked content and walked off to go talk to Leo. They'd been getting closer and closer lately...

Nico let himself get distracted by the thought. Hazel and Leo, the two were fated to be together. How did he know? Well the monster told him...

The undead girl and the boy of fire are destined to share a life, but the boy who's form can shift shall soon be cast aside.

He felt kind of bad for Frank, but there was more the monster had told him. More about Hazel and Leo, they were destined to be together it had said, but at a price.

"Another price," Nice muttered, "I just hope this time somebody doesn't die."

At that he could hear the monster's laughter, mocking him.

Oh my dear demigod, somebody will die. And you shall be the one to take their life. Down, down, down, it's time for lunch, boy.
