Something's been bugging me, and if this has been made obvious in the comic and I've just forgotten I apologize. "Alpha", "Beta"; are these their names or their "positions in the pack"? Or perhaps rank designations in an organization? I ask because actual wolves do not have that kind of "alpha wolf" hierarchy and that misconception is a bit of a pet peeve. I just want to be sure from where I should be approaching this in my head when I read.
