Marcel (Theo Barklem-Biggs) is the kingpin of the Young Offender Institution. He's been locked up for four years, ever since they found a policeman's helmet in his glovebox.
He's softly-spoken, completely terrifying, and strangely obsessed with the Twilight saga. But don't make fun of him for this, or he'll cut your head off and use it as a toilet brush.
