Rarity's character takes a relatively sharp divergence from how she's shown in this episode later on. I think this was my favorite episode for years, but looking back at it now, AJ is still relatively the same and Twilight has matured beyond the antisocial bookworm architype, but Rarity feels like she's evolved in a way instead of matured or progressed. She was very prissy and valley girl-like which felt like character traits. Not so much now.
