Finan

Finan is an Irish warrior found chained as a slave when Uhtred frees him, and from that moment his loyalty is total. Fierce, quick-tempered, and darkly funny, he fights with a ferocity that borders on reckless, but underneath the swagger is a man who has already lost everything once and refuses to lose again.

Mark Rowley gives Finan a live-wire energy that never curdles into mere comic relief; the humor sits right beside real menace and real grief. He's the friend who will follow Uhtred into any disaster laughing, and that combination of loyalty, wit, and lethal competence makes him the show's most purely enjoyable presence.
