He was always different. He knew that. He couldn't hide his true nature very well from other wolves on account of his eyes, but he initially believed that didn't matter to him if that meant they treaded lighter around him or outright avoided him entirely, so long as his mission was still achievable.
That is until he met Aengus, the herbalist. He was the only one that didn't look at him with trepidation...When he wasn't sleeping on the job, that is. Others saw it as odd that the herbalist not only felt fine sleeping around him, but even seemed to prefer it, like Watcher was a sentinel. Watcher was treated with a kindness that he didn't know was possible for one such as himself. To that end, he has promised himself that he will protect Aengus to the ends of this Earth and the next.
