When Ray and Thomas met Devlin, the bodyguard stood silently next to him. After Devlin ordered his men to kill the McCall brothers, the two irishmen retreated into the house. Ray and Thomas gave chase, Devlin's countless miners failing to stop them. Eventually the brothers cornered the two men atop a cliff. The bodyguard noted seeing the wanted posters in his travels and the tales about the McCalls, before entering a duel with one of the brothers, which he did not survive.
The bodyguard was a tall man who wore a black hat, black vest, black duster, black trouers, and black cowboy boots. He spoke with a distinct Irish accent.
The bodyguard was a stern mercenary who was knowledgable about the McCall brothers. He was an expert gunman, but ultimately his skills were not enough to defeat the McCalls.
