On the train ride to Canterlot, everyone except Twilight, and an annoyed Saten who still dislkes wedding, happily discusses the wedding, and only Applejack notices Twilight's glumness.
When asked, Twilight says that she is still thinking about Shining Armor's neglect of her, though Applejack tells her not to worry.
At Canterlot, it is evident that there has been an increase in security: the train passes through a pink protective sphere encasing the city, there are many guards at the station, and Princess Celestia keeps watch with the aid of a telescope from the balcony of the highest tower. Shining Armor is happy to see his sister and affectionately calls her "Twily."
Twilight immediately berates him for not telling her about the wedding, but Shining Armor explains that he had no choice and Princess Celestia wanted an increase in security in response to an exterior threat. Twilight concedes but remains hurt. Shining Armor reassures her that she has always been, and always will be, important to him, and asks her to be his Best Mare.
Shining Armor explains that Princess Mi Amore Cadenza is the full name of Cadance, Twilight's former babysitter. Twilight almost instantly cheers up, she always adored Cadence.
However, Twilight sees Cadance acting out of character, and rudely brushes Twilight off. Shining Armor announces that Cadance will be monitoring the wedding planning. When he says that they are happy to have Twilight there, Cadance smiles at Twilight malevolently. Twilight finds this suspicious, but Saten says that the only thing suspicious is the lack of beer.
Twilight begins overseeing the wedding preparations, starting in a castle kitchen Applejack has been provided. When Cadance shows up to check the catering, Applejack offers her an apple fritter, which Cadance insincerely calls "delicious." Applejack gives Cadance a bag of fritters in case she forgets to stop for a meal, but when Applejack turns around, Cadance tosses the fritters into the trash.
Cadance's visits Rarity, who is working in the tower room she stayed at in Sweet and Elite. Twilight begins to describe Cadance's temperamental behavior, but Cadance arrives with her bridesmaids, (Lyra Heartstrings, Minuette, and Twinkleshine). Cadance ignores Rarity's greeting and appraises her dress. She says that she was hoping for more beading and a longer train, and turns her attention to the bridesmaids' dresses. Displeased, she demands that Rarity make them in a different color, despite the fact that her bridesmaids love their dresses. Rarity is more than happy to comply with the royal demands, but Twilight calls Cadance "Princess Demandypants" when Cadance is out of earshot.
After nightfall, Cadance meets Pinkie Pie inside the castle ballroom. Pinkie presents her flamboyant reception plans, which include a board game, carnival music, and dancing. Cadance compares the setup to a "party for a six-year old," although Pinkie Pie is oblivious to the insult.
Even to Saten, she she is overly rude to him, when he simply asks where the bathroom is.
But Saten, being Saten. Finds this hot.
Might as well get this reveal out of the way..
That's not the real Cadence..
Not sure what Chrysalis has to gain by acting like a spoiled bitch all the time.. I mean, your impersonating one of the nicest characters ever.. So maybe you should try being a little more in character when your at least in public..
