Charlie didn't automatically react to the questioning answer. He just looked at the junkie for a moment as if to consider what was said. Finally he gave a soft sigh, letting go. This was not something he could fix; this was not something he had control over. This was something he had to let run its course. He had done what he could, and as the man was committing no crime, Charlie Crews could do nothing more than offer what he had.
"Okay." He stood, nodding. "You have my card. Use it when you're ready." There was little to no judgement from the cop. He just nodded again. It was possible Charlie now felt a little responsible for this man; perhaps he needed someone to look after now that Ted was gone, or he just felt responsible for people who needed help. Charlie would probably look for the man now and then, but for now, he knew he'd have to let go and be patient.
"If you do become dangerous, call me for that too." He nodded. Help came in all forms after all.
