Kenny Stowton

Kenny works IT and cyber-intelligence for MI6, the kind of quietly competent son who gets overlooked in a family full of spies. Awkward around people, easy around screens, he is drawn into Eve's hunt for the killer almost by accident, following data trails with more enthusiasm than caution.

Sean Delaney plays him as endearingly unglamorous in a show full of style and menace — a normal, slightly gangly young man doing his job in a world of poisoners and assassins. That ordinariness is the point: he grounds the story, and his earnestness makes him easy to root for.
