definately Baby Derp... My thoughts: - This is the best episode of the series so far (for FiM fans), bar none (IMO) - Fluttershy wasn't as cute as I was imagining, but she was more realistic of a character, and I'm beginning to think that she is the oldest of the core 6. - The core 6's younger-self ranked by cuteness IMO: (they were all adorable) 1. Twilight Sparkle 2. Applejack 3. Fluttershy 4. Pinkie Pie 5. Rainbow Dash 6. Rarity - Addressing the problem with RD being the "center of friendship," perhaps there was something that aided RD's stunt that made her cutie mark appear, and that same element (appearing as a rainbow) aided other ponies across Equestria to get their cutie marks (of course, not limiting it to just the main characters). This hypothesis is probably too deep for consideration of a children's show. I don't think we can crown RD the "Cutie Mark Queen" just yet. - This episode should be required for watching when creating an OC in the RP forums, because I think it will help bronies create background stories for their character(s). One of the most frustrating things I've experienced when making a character is explaining their cutie mark backstory. The storyboard in this episode does a great job outlining what a cutie mark story should sound like and may also inspire bronies' creativity in their chracter(s).
