Now that's not how you play "I Spy". You're supposed to say letters. But I remember a commentary where they said they don't use real writing in the show because it makes it easier to sell to other countries so I guess that's why.

Why did Rarity put her crown on upside down? That was a weird little detail.

The worldbuilding in this episode is interesting. Starswirl is mentioned, Celestia(with blue mane?) and Luna are on the flag for some reason. I'm sure it's all been discussed to death but I've given up trying to figure out a cohesive history of Equestria.
