Nico’s eyes shone with recognition and raised his hand to greet the approaching demigods. He faltered when they didn’t respond, but rather continued walking slowly towards him. When they stopped, Nico glanced at their faces, worry shooting through him.
"Percy, where’s Hazel?" Nico asked, looking around as if he expected her to jump out from behind Jason’s back and scare him. He looked at Annabeth who looked away. Percy didn’t answer.
"Where is my sister? Where’s Hazel, guys?" Jason shifted uncomfortably while Piper turned away. Nico turned his eyes to Percy, fear slowly creeping up along with anger - furious, burning anger. Percy didn’t answer.
"WHERE is my sister?!" Percy looked up, guilt etched on his face, before he finally spoke.
"Dead. Sacrificed herself to save me."
It was as if he had been stabbed in the heart: first, a massive rush of shock and disbelief; he took a step back and looked around at them, as if expecting this to be some poorly-executed practical joke. His hopeful look was quashed when Percy finally looked him in the eye.
The next he knew, he was on Percy. Punching, tearing, screaming, kicking, swearing and hoping - hoping above all for Hazel to be alive - and cursing - cursing that she was dead again while Percy lived, cursing that he had lost someone close to him again at Percy’s hands. Percy didn’t even attempt to stop him. He just looked at him with sad, pitying eyes and let him carry on. It took the combined force of Annabeth, Piper and Jason to prise him off the battered, bruised and bleeding Percy.
