This story is a sequel to Rarity Makes a Ponequine
Chancellor Neighsay feels personally offended; as Tilight Sparkle is challenging his authority. At least, it is how he feels, when she is standing him up; not just once, but twice.
What an upstart; thinking she could challenge him and the authority, he built up.
He thinks; Twilight needs to learn her place, if he needs to play it dirty, so be it.
Niece and Nephew should fit right into this plan; Twilight and her friends do not know or recognize them.
Two ponies are about to enjoy their time, Royally; while another will be facing a challenge he had never been prepared for. What the ponies are awaiting, is in a pair of very capable and slippery hooves.
A Marshmallow at the helm; riding the adventure as she pleases, to the destination of her choice.
It was a nice read but it looked too much like the other two stories.
