Rarity has grown a business empire, Rainbow joined and is a successful Wonderbolt, and Fluttershy is rockin a full on animal sanctuary. While calling the stories of some of these aforementioned ponies "Closed" might be a little pre-mature, their goals have definitely been met, and I wouldn't feel like they hadn't been explored enough if we don't get anymore exploration out of them by the end of the season.
Quite a few characters are still largely unexplored though. From the princesses to side ponies, there is a lot of potential out there for a good episode or two exploring them.
Who do you think needs some closure before G4 officially ends? Pick the character for the comments below.
