Story Notes:
This is the bit where I tell instead of Show because I am a bad writer.
-Scootish. The extra O wasn't rocket science but now the pony is named after the pony country which is actually named in reality after the pony. This may be a meme of some sort 
-Fluttershy's accent is indeed a reference to John Barrowman.
-Steel Talons and GDI are a C&C reference of course. And another story idea.
-I've decided Derpy/Ditzy is older than she looks so she can have two daughters.
-Pinkie's flying machine can't have been certified safe by the Royal Aviation Authority.
-Rarity swears to Luna because more ponies should, if only to stop her trying to convert another wine cellar into an S&M dungeon.
-Apologies for Dashie's rambling at the end. It may need some work done to it again.
