Hindsight

When Jake knew that there was another one in the nest, he immediately had an idea. What if he could use the remaining dinosaur with a definite vengeance as a sword. 

A sword that they could use against many, many enemies in the vast jungle. 

So they started with a plan in place. The scent that they decided would be the one to take the blame was one that could be easily replicated only by humans, who were non existent in this secret realm. 

It was meat that was properly cooked. A good meal for sure, but not a meal that anyone here could make. 

This meat was in the cave, fueling the father dinosaur's rage, and it was also creating a path. 

A path away from the direction that Jake was running toward. 

There was no way that someone as stupid as the dinosaur would understand that it was a diversion it was following. And it would follow the scent as much as it could, until it would mysteriously vanish.
