[Nico continues on with a soft smile that gradually fades into a solemn expression.] Artemis asked if my sister wanted to join the Hunters. She did. We hadn't been claimed yet so I stayed in the Hermes cabin. Artemis went missing so the Hunters went on a quest to go find her. Bianca... didn't come back. Percy was on the quest too and when they got back, he was the one who told me she didn't make it. She'd died saving them but... I was ten and I'd just lost the only family I had left. I ran away from camp because I was scared. [That's not a lie, but he doesn't add in that that included him being scared about his feelings for Percy.] I had nightmares about what was happening, and I could sense that her soul was being judged in the Underworld. It was the first time I ever really used any abilities I had. [In an attempt to lighten things up though, he adds:] You know that crack in the dining pavilion? Yeah, that was me, unintentionally finding out I could make fissures in the ground.
