"Why?" Nico sobbed into Will's chest, Hazel's image burned into his eyelids.
Nico had just gotten the news of the mass attack on Camp Jupiter, where all the people who followed Octavian joined up and tried to fight Reyna for power, not realizing that many still were loyal to her.
Hazel and Frank both died in battle.
Will held Nico close, Nico hugging back desperately as he hiccuped.
Jason didn't know how to react; Piper had to charmspeak them both into eating and sleeping.
Percy and Annabeth were hardly better. They somehow managed to eat and sleep, but only a little.
Piper had no one to force her to eat or sleep but herself. She thought about the others, and how they needed her.
One day, she cracked. She broke down sobbing, the guys and girls in the Aphrodite cabin trying to calm her down.
Soon, she stopped trying. The others, even Percy and Annabeth, fallowed in her footsteps.
Will tried desperately to get Nico to eat, but it was a fruitless effort.
One day, Will died during a training session gone wrong. The next day, an Apollo cabin member went into Nico's cabin, seeing a body hanging from the ceiling with a message carved into their wrist; I'm Sorry.
