John B

John Booker Routledge, known as John B, is 16 years old at the start of the series. He is played by Chase Stokes. He is the leader of the Pogues, a group of friends from the poorer part of Kildare Island. He lives alone in the Chateau, a simple, old house, without adults—and this has been his reality since he was very young.

His mother left when he was only 3 years old and never returned. His father, Big John, disappeared at sea 9 months before the start of the series. His body was never found, and everyone thinks he's dead—but John B never believed it. He was sure his father was alive. His uncle Teddy, who was supposed to be his legal guardian, went to work in Mississippi and left him alone on the island, without any adult supervision.

JJ: his best friend since he was 9 years old. They're like siblings—they protect each other, cover for each other, and never abandon each other. Pope and Kiara: inseparable friends. The four of them form a family they chose, since none of them had a perfect home. He's the heart of the group—the one who keeps them all together when everything seems to fall apart.
