Castiel blinked, then slowly turned his head and looked at the figure next to him for a long moment. Then, he nodded.
"Symbolism," he said simply. It was incredibly powerful, especially for mortals who only had tales to inform them of ancient evils and danger.
He turned back towards the City. Daredevil reminded him somewhat of Sam; embracing the darkness in order to try to do good. Of course, this being had no taint of evil, and would only falter if he allowed himself. The Winchester brother had had to struggle against an onslaught of addiction and true evil, attempting to corrupt his intent. However, this man had no such affliction. Castiel didn't have to look into his eyes to know that; he may have lost some of his power but he could still sense a demon from a mile away.
