Or both! He could be both. Yeah, I really like the idea of the other character being a private detective and him having even personal matters in the case would be better. Since, it just means that he wouldn't be too happy with my character at first. I do want to make my character a magician (which isn't really going to be a secret, like the first time this guy sees something weird go on, my character would probably use magic in front of him.) which would just make thing a lot more fun. I could even see it being where my character might be from some other magical law enforcement that isn't exactly known to the government, so that would mean even more fun in the future.
