What you're still missing, however, is the point I'm trying to make. Let's take Joe as a doctor, for example. Do you really think Joe was introduced as "studying to be a doctor" at the outset of 02 because of what they wrote in a CD drama? Or do you suppose the latter begot the former? And more important, would any viewer really be at a loss on that particular point of character information if the two anime series were all they ever saw or heard?
