James had seen the sudden appearance of the form now turning toward him. Though he had been moving silently, the man still seemed to know when he was near enough for combat - or speech - or an offer for... something altogether different from both of those things. James had approached with caution. Though he had yet to fill his knife hand with a hilt, he kept the thought in mind.
"What are you?" James asked directly. Another HYDRA experiment, escaped as well? Or worse, a HYDRA agent, tracking him down? James would not be going back. He was ready to fight and to die to remain with Steve and Ariel and to stay away from HYDRA. Just because this man in a trenchcoat seemed unarmed, it didn't mean that he was harmless. Clearly, he had some sort of power. Normal men could not appear out of thin air. Even James couldn't manage that feat.
