Chapter 1
It's been one week since the Royal Wedding. Shining Armor gained a wife and Twilight Sparkle gained a new sister. But now Twilight misses Cadence and their old wacky antics as young fillies, however; because she is a Princess, their time together is rare. The only way Twilight can summon Cadence to Ponyville is if there is an absolutely good reason.
“Spike, Take a note.”
It's a regular day for the Mane 6 in Ponyville. Twilight is in her library, as usual, reading up on subjects that most ponies wouldn't even think existed.
“Dear Princess Cadence, I'd like to report that there have been several arguments arising in Ponyville amongst some of the couples. While this may not seem important now, it is actually causing some ponies discomfort and others the inability to work.” she told Spike, her baby dragon assistant, to write.
“Inability. . . To. . .work. . . Okay, Got it.” Spike says, wiping at his forehead as a gesture of completion and “hard” work.
“Thank you, Spike. Now you can send it.” Twilight says. Twilight props her upper body on the window sill, staring out the window to the village she has come to love over the years. She looks up to the sky, sighing, day dreaming about her days as a filly with Cadence.
Spike sets the quill down, wraps up the scroll, and sends the letter by engulfing the letter in a green blaze.
“You really miss Cadence, huh?” Spike says, walking up next to Twilight,
Twilight sighs, pushes off the window sill, and facing spike.
“I thought that since we're sisters now, she'd at least make some time to come see me.” Twilight says.
“She is a Princess after all, she could just be busy with royal matters.”
“I know, Spike. But still, you'd think she could at-”
Spike burps, green flames shooting in all directions in his mouth, and then comes a scroll. Twilight uses her magic to levitate the scroll in front of her face.
“It's a reply from Cadence!” Twilight squee's with joy.
“Dear Twilight Sparkle, I will be glad to let you know that tomorrow I will be visiting Ponyville to check upon these problems. Princess Celestia has assigned this issue to me because of my way with love,” Twilight reads the letter out loud. Twilight then sets the scroll down on the podium.
“I can't believe it Spike, I finally get to spend time with Cadence,” Twilight says. “She's actually coming.” She squee's again.
“So what now?” Spike asks.
“I'm going to go make a list of all the couples who are arguing. The faster Cadence stops the arguments, the faster we can spend time together,” she replies.
Twilight then levitates a scroll, a quill, and some ink. Spike hops onto Twilight's back and holds the ink for her.
“We'll make our way down to Sweet Apple Acres and back, I think we'll have all the couples listed by then,” Twilight says as she opens the door and walks out, closing it behind her.
As they make their way through town, Twilight and Spike look for any arguments that are stirring up. They spot a couple arguing just outside sugar cube corner about who knows what.
“Dream Caster and Corba Force,” Twilight reads aloud and writes.
They continue their search and find another couple arguing on top of the bridge that leads to Fluttershy's cottage.
“Sun Shower and Flitter,” another couple on the list.
The last couple they find are arguing just outside the fence of Sweet Apple Acres.
“Blaze Fury and Apple Cider. Okay Spike, we're done.”
As they head back to the Library, Twilight stops at Sugar Cube corner to pick up a few cupcakes for her and Princess Cadence.
“This is gonna be so fun,” Twilight says when they finally reach the Library.
“I wouldn't get my hopes up too high if I were you Twilight,” Spike says doubtful that Cadence would stay long after her job is done.
“Oh, Spike. I'm sure Princess Cadence would allow for some time to spend with her new sister,” she assures him.
“If you say so,” Spike finishes the conversation. He hops of Twilight's back and casually puts away some books that lay abandoned on the floor.
“Spike, I need you to clean up this place, I just realized how messy it is,” Twilight says, levitating some books in front of her to see what they are.
“On it,” Spike says, picking up a book in each claw.
Hours pass as Twilight reminisces about her filly hood with Cadence in her photo album while laying on her bed. Spike enters the room tired and beat.
“I'm all done, Twilight,” he says then yawns.
“Thank you, Spike.”
“Watcha lookin' at Twilight?” Spike asks, climbing up onto the bed with her.
“I'm looking at my photo album of me and Cadence,” she says, raising her hoof to point at a picture of her and Cadence with birthday cake all over their faces. “This is 3rd birthday party. It's the first one Cadence celebrated with me.”
Spike pointed and laughed at the picture next to it. Twilight's face turned red in embarrassment. The photo clearly shows Twilight sucking on her hoof as a small filly, while Cadence is holding her.
Twilight closes the book and sets it on the floor. “Time for bed, Spike.”
“Fine,” he says, still willing to see more photos.
Twilight turns out the light and situates herself under the covers. Spike finds a comfortable position within his basket bed and whispers, “Try not to suck on your hoof tonight, Twilight.”
“Ugh, Spike!”
“Sorry, Sorry. Goodnight, Twilight.”
“Goodnight, Spike.”
A few moments of silence pass before Spike starts laughing once again.
“Spike. . .”
“Night.”
Spike concentrates on containing his laughter. Twilight finally falls asleep, only to dream about the old days with Princess Cadence and the new times they'll share tomorrow and so on, while Spike, being Spike, dreams of Rarity.
It's a midsummer day. Twilight and Cadence are at the local park in Canterlot. Cadence pushes Twilight forward while Twilight swings. “I am so lucky to have you as my foil sitter, Twilight says.”
“I'm the one who's lucky, Twilight,” says Cadence.
“You're a princess. I'm just a regular ol' unicorn,” replied Twilight.
Cadence wraps her hooves around Twilight, picking her up off the swing set. “You're anything but a regular ol' unicorn,” Cadence says, setting Twilight down. Then they start their chant. “Sun shine, Sun shine, lady bugs awake. Clap your hooves and do a little shake.”
