Marcus' brother Sebastian. The youngest of three, he's in Rocco's grade.
You know how there's jocks, but there's also "wannabe jocks"? Yeah. Sebastian's on the basketball team, but that's the most you could say about him. He's on the basketball team.
He's more of a band nerd who's also an enthusiastic amateur baller. That's how Rocco knows him. They play pickup games together in the lions' driveway.
He's also occasionally bullied by the middle brother, Gareth.
