Heather's not really normal, though. The difference between Gwen in Island and Heather in World Tour is that I don't think they intended for the audience to relate to Heather as much as we did (or at least as much as I did). She was our designated protagonist but Cody was a lot more of an Average Joe. Heather had that whole villain-turned-good-guy plot going on and was a lot more interesting in comparison.
