The Doctor closed the large cloth-bound book and set it on the table. Nowadays when he wasn't in the TARDIS, he was spending most of his time catching up on the thousands of years of pony history he had missed. He had been intrigued to learn that not only ponies, but all the hooved mammals were sentient, and had even spent a day talking to Applejack's cows to learn about their culture and relationship with the ponies.
Getting up, he walked through the book shelf laden main room of the library over to the kitchen, eager to share his discovery.
"Sparkle!" he called as he nudged open the door "There was something in the Paleopony Period I wanted to check out, something about a giant shark that I'm not sure is entirely from your planet in origin. Are you in?"
He cut off suddenly with a yelp as he was almost brained by a large pan that was whizzing through the air. As he looked up, he saw that it, along with several other kitchen implements,  were racing around the room at breakneck speed with magical auras around them. The purple unicorn in the middle of it all looked up, and all the utensils and cookware froze in midair.
The Doctor eyed the large cutting knife inches from his head, and took several smart steps in the other direction "What in the world are you doing?"
"Dish-washing" Twilight replied, as if that were obvious, as she talked, she shelved the clean dishes with her magic, scrubbing of the last with a dish towel (also floating in midair) before sending it into the cabinet as well. Simultaneously, the dirty dishes stacked themselves neatly and returned to the sink for a later time.
".... Dish-washing." The Doctor shrugged "Just when I think I'm done being surprised."
"I don't think you're allowed to judge Mister time traveler....." his purple friend said, rolling her eyes falling into step beside him as they headed out into the main room of the library " But anyhoof, you were saying something about shark aliens?"
They pushed open the back door and walked up to the TARDIS, which had been residing in the back alley behind Twilight's library since she had started traveling with the Doctor. 
"Oh!" the Doctor said "That reminds me... here!" from out of her saddlebags (which he was still wearing) the Doctor drew a small object on the end of a chain, tossing it to Twilight.
The purple unicorn caught it in her magic, looking at it curiously "A key?"
"A key to the TARDIS!" the Doctor said brightly "Figured in might come in useful"
Twilight smiled, one corner on her mouth curling upward in her usual half-grin, then levitated the key into the lock with her magic, saying "Well...in that case" the door swung open "After you"
The pair stepped into the time machine, laughing, and as the closing doors, a brief conversation could be heard.
"You know , Sparky...I always wondered  exactly how unicorn magic work-"
"Sparky?"
"...oh no."
"We made an agreement Doctor."
"Sparkle......Please don't say the catchphrase...it's such an awful catchphras-"
"C'EST PARTI !"
"NO. Stop it. Stop it right now!"
"C'est parti! C'est parti! C'est parti-"
Then the blue doors swing closed, there was a strange sound, and the blue box faded away, leaving no signs it had ever been there.
