This probably isn't as bad as it looks

Oh dear... um, Angel? Don't turn around. Things have gone... awry.

Princess Fluttershy, um, that is... if that's alright with you.  Formerly a pegasus from Ponyville, she primarily cares about animals and her friends.  Unlike most alicorns, she is not ascended by Celestia or Luna, instead having gained her alicorn powers from Discord.  Said alicornification also may have scrambled something in her brain... or maybe tha's one of the oodles of clones that have started cropping up.
