Other kids

The real question is why did they not return to the village after the raid? It was the only home they knew so it makes no sense for them not to return. Oddly enough, a vital part of the plot depends on this hole in logic. If they returned, they would have found Jaguar's wife and managed some way of getting her out. But if they had done that, the tension and suspense of Jaguar racing back home would be gone.

I kept hoping that the little kids would hold on until Jaguar's Paw made it back. Then all of them would go deeper into the forests and start a new village. Maybe not realistic, but it still would have been nice. :)

I too wondered what happened to the kids. I don't think they went back to the village or they would have found the lady in the hole. It's morbid to say but unless Jaguar Paw found them after the end of the movie, they probably died. They were children, and half of them appeared to be very young children at that. The older girl probably only knew how to gather plants..possibly prepare an animal for cooking but none of them knew how to hunt.

Remember the "here come the Spaniards" scene at the end? If any kids did survive it's forced baptisms and conversions, new names and welcome to slavery.

Another question regarding this. What happened to his fellow tribesmen?
