I really need to watch more of season 4, especially the "key" episodes (I've only seen Rarity's and Fluttershy's, and Rarity's was the superior of the two for me).

Appropos of nothing; I feel that fans of the show should take a look at this; Shazzbaa - Double Z, Double A - My Little Pony: The Elements of Harmony it's very well written, and makes perfect sense about the show. I already gathered about "The Magic of Friendship" being Twilight's true elemement (I don't know why so many don't seem to realize that), but rest of it make me appreciate the show even more.
