As far as Rick could likely detect, there was nobody else around to harm him or interact with him. However, there was in fact something interesting. A large plume of smoke was visible through the canopy above him, coming from the direction the duo had been camping in the night before. That being said, the clearing he was in felt.. different, somehow. It was difficult to put a finger on, but there [i]was[/i] something off about it.

As for the piece of paper, it was simple enough- it was crumpled, obviously folded and unfolded again and again over the years.
A picture.
Edmondo, standing beside a happy-looking woman around the same age, and two small children.
The young boy had a wide, cheesy grin stapled to his face, and a large band-aid on his cheek.
The girl wasn't quite as enthusiastic, staring at something off to behind and to the side of the camera, possibly the photographer.

However, the thing that likely stood out to Rick the most was the fact that the woman, presumably Edmondo's wife, was familiar to him.
She was one of the Mage's he'd seen in the dossier prior to his embarking on this mission. One of the Mages who'd been taken.

It seemed there was one final piece of evidence that could possibly point him in the right direction; sitting on the edge of their little clearing, right where they'd entered it on their trip from the path from the bridge, was something barely visible in a path of grass that was thicker than the rest. Almost as if someone had attempted to hide it.

It was matte black, and not paper.
It was hard to make it out fully, but whatever it was, it wasn't natural.

It was time for Rick to put his noggin to use, it seemed.
