Was Kenneth the Third aka the Grim the heir of Kenneth the Second despite being his nephew, not being the son of the current king, and younger then Maol Chavilm? The show comics and real life are kinda of confusing regarding Scottish succession.
Kenneth III was the son of Kenneth II's older brother Duff, so he was the rightful heir.
