William Bullock
Played by Josh Eriksson
Polite and well-mannered, eight-year-old William is Seth Bullock's nephew, turned stepson after Seth's brother is killed and Seth weds his brother's wife. Well-mannered though he is, he can't resist staring at the jiggling breasts of the prostitutes with whom he and his mother share a bumpy stagecoach ride into Deadwood, nor passing gas in the close quarters, to the bemusement of his mother. Arriving in Deadwood in the midst of a pitched battle between his adoptive father and Al Swearengen, William's innocent look catches the enraged Swearengen's eye, pulling him back from the edge of violence.
