I've been away from the show and fandom for so long due to work and shifting interests. However, recently, I've been getting bored and decided to get back into it. I picked up where I left off, about half-way through season 5, and this episode... Wow!
First of all, I love CMC episodes (despite a general disinterest I've noticed from a lot of people) and I also love episodes with songs, so even without all the character development I still would have loved this episode. To be honest, though, I wasn't sure what to think of it all at first. Silver Spoon turning on her best friend and Diamond Tiara redeeming herself. It didn't seem right. Even though I wanted it to happen, it seemed too sudden. Likewise, when the CMC got their cutie marks, it seemed like the wrong time and their cutie marks didn't make sense to me at first. By the end of the episode, though, it all came together nicely and made sense, for the most part.
There were a couple of things I still didn't understand, though. If I remember correctly, their special talents are helping other ponies find their special talents. That can't be all though. For one thing, they're surely not going to do that for the rest of their lives. I mean, it's fine while they're still in school, but when they grow up, they're going to go out and get jobs. That leads me to the other thing I don't quite get. They each have different symbols in their cutie marks which, I assume, represents their secondary or true special talents. Sweetie Belle has a music note and we all know she's good at singing, so she'll probably be a singer, but I don't understand Apple Bloom and Scootaloo's symbols. Apple Bloom's is an apple, but I thought she was good at building or making stuff, so how does an apple represent that? Also, Scootaloo has a lightning bolt. I know she envies Rainbow Dash and wants to fly, which may imply she's going to be a Wonderbolt, but she's not good at it. She's just good at going fast on her scooter. Maybe she'll get better at flying later on. Maybe she'll even get good enough to join the Wonderbolts. That would make for interesting character development and an emotional episode if it ever happens, but it's all still a mystery at this point.
Needless to say, I'm excited after watching this episode and can't wait to see what this all means for the future. I had lost interest for a while but after this, I think I'm hooked again.
