Here's hoping she gets another Pinkie Pride-esque episode. While I can't say she is my favorite pony now (as I no longer have any real "best pony" ideology anymore) my top favorite episode for seasons 1, 2, and 4 have been centered on her. 1 was Party of One, 2 was the Smile episode, and 4 was Pinkie Pride (though, now that I think about it, season 4 had a bunch of other episodes that compete with it). Can't say for sure with season 3. PP will always be my first favorite. When she's done right, she's done phenomenally.
