Wrong Side Out

This AU diverges during The Titan's Curse: Bianca di Angelo survives the quest, and Annabeth Chase dies instead. That single change fractures the prophecy, the friendships, and the emotional core of the series.

Bianca's survival keeps Nico grounded. Without the trauma of losing his sister, Nico never becomes the Ghost King, never spirals into isolation, and never develops the dark, brooding persona he's known for. Instead, he remains the bright, earnest, Mythomagic‑obsessed kid he was before the quest - still brave, still protective, but emotionally stable and deeply connected to Bianca. But with the cost of Will Solace's love

Annabeth's death devastates Percy. She was his strategist, his anchor, the person who challenged him and believed in him. Losing her shatters him in a way no monster ever could. He becomes quieter, more reckless, and more afraid of failing the people he loves. He carries guilt like a second skin - guilt for not saving her, guilt for surviving, guilt for moving on.

In the aftermath, Percy and Bianca form a bond built on shared trauma. They were the ones who lived through the moment everything changed. They were the ones who saw Annabeth fall. They were the ones who had to keep going. Their connection starts as grief‑comfort, then grows into something deeper, messier, and harder to define. It's not a soft romance - it's two people clinging to each other because they don't know how to stand alone.
