Isiah

Isiah is one of the younger members of the Peaky Blinders, quick with a joke and quicker to prove his loyalty to the Shelby family. He dresses sharp, talks fast, and wants respect and a real place in the gang's inner circle, even when the older men treat him as an afterthought.

Daryl McCormack gives Isiah a live-wire energy that cuts through the show's heavier gloom — he's funny without being a joke, ambitious without losing his warmth. The writing uses him as a way to feel the gang from below, and McCormack makes that vantage point charming rather than pitiable.
