My mane (lol) question would be why is Rainbow Dash running away from Pinkie Pie? Haven't they been friends for a while? I mean I know we don't know when or how they met, but it seems pretty established that before Twilight comes along that Rainbow, Applejack, Rarity, Fluttershy, and Pinkie are all friends. Course I could be wrong and they all became friends at the same time. That being said I love how they know who to trick and how much each of their different friends can handle it. I loved seeing how certain ponies interacted with each other and how their friendships were already established. I am glad that Rarity didn't take offense or make an issue about Gilda being such a jerk about the tail that she wanted.
I really appreciated seeing Pinkie Pie try everything she could to make friends with Gilda and that she didn't go with her first reaction of "She's a jerk." It's true, but she at least gave her the chance to prove that she wasn't/isn't.
