I originally wrote this teacher as providing a one panel explanation, immediately followed by what will now be the next comic.
The reason she wound up getting a full comic to herself was I felt some explanation was necessary, but the panel she took up didn't leave enough room for the rest of the comic.
As for her design, I wasn't really sure what I wanted going in, and wound up with this. I like how she turned out enough that she might get a doppelganger when we move on to college years.
Or, heck, she could just get a job at the college. I dunno.
The exercise they're doing is based on one I vaguely remember doing in school, though it's possible I've given her class more of a reason to be doing it than we had. I don't even remember what the point of us doing it was. Maybe it was just practice discussing things?
