Finn Shelby

Finn is the youngest Shelby, still a boy trailing after his older brothers with open admiration, eager to prove himself worthy of the family name and the cap they all wear. He watches Tommy, Arthur and John run Small Heath like it's a film he's desperate to be cast in.

Harry Kirton plays him as the family's unclouded innocence, the one Shelby who hasn't yet been ruined by war or business, which makes him a quiet emotional barometer — you measure how dark things have gotten by watching how eager Finn still is to belong to it.
