Proof
Back at the farm, Jesse didn’t believe what Nick had told him. There was just no way in his mind that a pack of wolves was living in harmony with a horse. That just went against nature, and they would for sure have eaten Bessie by now. But Nick insisted it was true.
He told Jesse that if he didn’t believe him, he would go back out there and get video proof of what he saw. It was going to be difficult and maybe he would never find them again, but he needed to try. After all, maybe he would be able to take Bessie back home.
