Things had taken a rather drastic turn, from a peaceful group to reveal a wolf in sheep's clothing, one would think karma existed with what transpired but Jason's life was now in danger.
He was the one that suffered the consequence of this action.
Sam and Clementine instructed Rachel to watch over the kids as they trailed Jason's path.
There was no way that his boots didn't leave a trail and that was what they used to their advantage.
They arrived there in little to no time, Sam noticed that there were multiple footprints but after that, they disappeared. Whoever came along knew how to cover their tracks.
The fact that he left these other footprints here told Sam that this was a message to show them that Bella wasn't alone.
Was this an intimidation tactic to make them give up chasing?
