The script was partially based on the abduction of star athlete Kari Swenson by Don and Dan Nichols, a father and son who lived in the wilds of Montana.
Unusually for an immortal of the "Highlander" franchise, Caleb Cole is not using a sword in combat. He uses a battle axe.
The episode features a flashback to c. 1873. Duncan is being trained by immortal tracker Carl the Hermit, improving his own tracking skills.
Caleb Cole is described as a widower and has apparently not even seen a woman in several years. This is apparently the reason he lusts after the pretty Tessa Noel and wants to mate with her.
Starting with this episode, the opening narration and scenes have changed. It no longer starts with Duncan announcing his name.
