He was named Niko in the beginning but I eventually just referred to him as "The Boy". Originally the story was that he was entrusted with a mouthpiece by his father the village Chief and it was a right of passage for him to summon the cactus gods. I cut it out because I had no clear and fast way to tell the audience that this was the situation. Niko still is the village chief's son and is granted the duty of village chief after the cactus gods finish their business. The Village Chief just isn't shown in the film. This would be said on the commentary if there were a DVD with special features.
