Who Are Nico and Bianca di Angelo? Meet Percy Jackson Season 3’s New Demigods

If you’ve only watched the show, these two names mean nothing yet. If you’ve read the books, you’ve been waiting for them since Season 1 was announced.

Nico di Angelo is one of those characters who turns up halfway through a series and quietly takes it over. He and his sister Bianca arrive in The Titan’s Curse, the third book, and Season 3 of Percy Jackson and the Olympians (premiering November 20 on Disney+) is where the show finally gets to them.

Nico and Bianca’s Introduction: The Westover Hall School Dance

The introduction is a strange one. Grover has been undercover at Westover Hall, a military boarding school in Maine, and he’s found two demigods there, a brother and sister who have no idea what they are. So Percy, Annabeth and Thalia walk into a school dance and try to blend in while they figure out how to get the kids out, which would be easier if the vice principal, Dr. Thorn, wasn’t a manticore watching the whole thing. The first footage Disney showed from this season is that dance, including Percy and Annabeth having to actually dance together in the middle of the rescue, which book readers recognised instantly.

Bianca is twelve in the book, Nico is ten, and calling her his older sister doesn’t quite cover it. She’s been raising him. Their mother died when they were small, there’s no one else, so Bianca is the parent, and she does it the way a twelve-year-old would, half patient, half at the end of her rope.

Nico, meanwhile, is obsessed with Mythomagic, a card game about the Greek gods, full of figurines and attack values and arguments about whether one god beats another. He’s a kid who talks too fast and asks too many questions. Percy finds him slightly annoying, honestly. That matters later.

Then there’s the part of their story that makes people sad every time it comes up. The di Angelos were born in Venice in the early 1930s. After their mother was killed, they ended up in the Lotus Hotel and Casino, the place from Season 1 where time barely moves and nobody ever wants to leave. Percy lost a few days in there. Nico and Bianca lost about seventy years. They thought they’d been inside for a month. Bianca is twelve and also, technically, in her eighties. Everything Nico knows about the world is decades out of date, and Mythomagic is about the only thing that’s his.

Who Plays Nico and Bianca di Angelo?

Levi Chrisopulos plays Nico and Olive Abercrombie plays Bianca. Chrisopulos was 14 when he got cast, and his last callback was reading scenes with Walker Scobell, after which Rick Riordan sent him a video message telling him he’d got the part. Scobell says he knew from that first read it was going to be him. On set, Chrisopulos kept a diary written as Nico every night. That’s a lot of homework for a 14-year-old, but this is also a character people have had in their heads since 2007, so the pressure is real and he seems to know it.

One thing Season 3 is doing differently from the book: you’re actually going to see Nico.

The Titan’s Curse is told entirely by Percy. Percy goes on the quest, Nico stays at camp, so for a big stretch of the book Nico just isn’t there. TV isn’t stuck inside one person’s head, so the show cuts back to Camp Half-Blood a few times to check on him. “He’s a bigger part of the entire season,” Scobell has said, and he and Chrisopulos both say Percy and Nico end up a bit closer here than they are in the book at this stage. Nico’s excitement about all of it, the gods, the camp, the monsters, reminds Percy what this world looked like before it started costing him people. Bianca goes out on the quest with Percy to find Annabeth and Artemis, Nico stays behind, and this time staying behind comes with a storyline instead of an absence.

Who Is Nico and Bianca’s Father? (Book Spoilers)

Everything from here down is book spoilers. If you haven’t read The Titan’s Curse and you want Season 3 clean, stop at this line.

Seriously, last chance.

Okay. Nico and Bianca are children of Hades. The book saves that reveal for the end, and it lands the way it does because of everything that happens before it.

Bianca joins the Hunters of Artemis almost immediately, within hours of being rescued. Immortality, a bow, a life of her own. Reading it as a kid, it feels like she’s abandoning Nico. Reading it as an adult, it feels like a girl who has spent her whole childhood being a mother grabbing the first door that opens. Both readings are kind of true, and that’s why people still argue about Bianca nearly twenty years later.

Percy promises Nico he’ll look after her on the quest. He means it. It doesn’t matter. In the Junkyard of the Gods, the quest runs into a defective Talos, a giant metal automaton, and Bianca climbs inside it to shut it down after pocketing a Mythomagic figurine of Hades, a present for her little brother, the one god whose figurine Nico didn’t own. She doesn’t come back out.

When Percy has to tell Nico, Nico doesn’t just grieve, he erupts. He banishes a crew of skeletal warriors straight back to the Underworld in front of everyone, which answers the question of who his father is in the worst possible moment, and then he runs from camp. The cheerful kid with the card game basically ends there. The Nico most fans carry around in their heads for the rest of the series starts in that scene.

Whether the show follows the book exactly, nobody outside Disney knows yet. But the changes they’ve talked about, more Nico at camp, more of a bond with Percy before the quest, look a lot like a show building something up because it knows what’s coming. If Season 3 gets Nico right, this is the year casual viewers start reading the books, and if you’ve seen the rollout you know there’s not long to wait: two episodes on November 20, two more every week after that, done by December 11.
