Here's the link to the synopsis for Episode 23. And here's the link to the extended synposis'. "Leap of Faith" is looking ever more likely to be Applejack's key episode, but the extended synopsis' don't really provide us with much to go on. Episode 23 is a Spraity episode, giving Rarity a total of 4 focus episodes this season. Beating out Pinkie Pie, and Fluttershy, and tying with Applejack for most episodes this season. I guess you can call this season "The Rarijack Season" in addition to "The Duckface Season". This could be the episode that has the early 90's reference tweeted by Meghan back in 2013.
