This was such a fun episode, I loved it! I knew AJ was going to get her key in this episode. It's kind of strange how the rest of the mane 6 were absent for the entire episode, though. I was actually hoping that Flim and Flam would redeem themselves at the end of the episode too, but I guess they didn't. They're still my favorite ponies anyway. And their new tonic song is so catchy, I listened to the instrumental more than 20 times now. But don't get me wrong, the cider song is still one of my favorites. It's just so exciting to hear Flim and Flam sing again, they have really good voices. :3 Also, Silver Shill is adorable! And, is it just me, or do Flim and Flam seem a bit different than before? It might be their eyes. Anyways, I saw this episode three times already. "Leap of Faith" is definitely one of my favorite episodes of season 4.
