Nico

He felt a presence inside his mind. It was creepy. Sierra had somehow been able to access his memories.

But it was a nerve-racking feeling. The experience tore him through painful memories. Nico doubled over, his hands pressed against his temples.

**Reyna**

Nico doubled over and writhed in pain.

"Nico!" Reyna exclaimed. She rushed to his side. Whatever he was suffering from, it was happening in his head. Sweat formed on his forehead and he was gasping for breath.

Out of the corner of her eye, Reyna saw Sierra crumble to the ground. Nico stopped writhing in pain. He coughed, and Reyna helped him up.

"OK," Nico paused to catch his breath. "THAT HURT. She's definitly a demigod."

Annabeth touched the girl's forehead. "What the hell just happened?"

Nico shivered. "That momentary eye contact gave her a glimpse of my memories. I could feel her in my mind. It was really creepy."

Annabeth's eyes widened. "She's barely breathing, and her pulse is erratic."

Percy eventually agreed to carry Sierra until she awoke. When he lifted her weak form, he winced.

"Wow, this girl needs eat more! She feels like a paperweight!"

"Come on, Percy!" Annabeth rolled her eyes as she got Sierra's backpack.

Reyna helped Nico walk until he could walk by himself. Reyna had been im Central park to meet up with Nico, Percy, and Annabeth because she would be visiting Camp Half Blood. She was glad that Sierra was there. She looked like she needed help.

And after what had happened, Reyna was now absolutely sure of that.
