User blog comment:Weavillain/How Far Should Character Development Go?/@comment-31165208-20170730205134

If Lola were to become all nice and no mean, it would completely ruin her character and her reception would go downhill. She would become a Mary Sue.

As for that last question, I believe that some viewers didn't think Lynn had no character development in Lynn-er Takes All because it is small and can even be unnoticeable. Lola, on the other hand, proved herself trustworthy and stepped up her game.
