The growl seemed to have his desired effect. The man stood stock still in front of him, obviously afraid. He could smell it, but he didn't run right away. Curious. He took a step closer into the clearing. Seeing the man turn tail and run had the desired effect. Eric could feel the wolf pulling him towards the retreating man like a magnet. All he wanted to do was scare him, maybe teach him a lesson that full moons weren't safe for non-weres to be wandering around the woods.
He kept himself low to the ground following the man as he fled. Pulling back against the instincts that told him to sprint after his quarry and attack. He saw the root before the man did and watched as he tripped. The opportunity pulsing through him, it would be too easy for him now. Fear was evident in his eyes as he approached.
