	Princess Celestia was in her castle, on her throne, quickly looking through various papers. She was well aware of the crisis occurring in Ponyville, but she had faith in her student, she knew that she wouldn't let her down. And Also, she had faith in a certain ages old pony who was doing his own to stop it.
"Princess Celestia, you look like you haven't changed a bit," The Doctor announced proudly, swaggering into the throne room like he owned the place, followed by a smaller, viridian mare.
Right on cue, Princess Celestia thought, "Doctor," She nodded, acknowledging his presence.
"Now that we've gotten the formalities out of the way," The Doctor said, "I've got some questions for you."
Princess Celestia nodded, "You have my attention."
"The Vashta Nerada, they listen to Luna. Well," The Doctor corrected himself, "They were supposed to, why?"
Princess Celestia sighed, "I have no idea what you're talking about."
"That's a lie," The Doctor confronted, "Its as if Luna tried to tame them-" He stopped as he had an epiphany, "Oh...but she didn't tame them, YOU did."
Princess Celestia was silent.
"Yes, it makes sense now," The Doctor said, "YOU tried to tame the Vashta Nerada, so Luna could command them, making her magic much more powerful..." The Doctor paused as he thought, "but it didn't work, did it?"
Princess Celestia took her chance, "The Vashta Nerada turned on me and took over Luna's body. they tried to ravage the kingdom, they would have killed everyone! I did what I had to do."
The Doctor nodded, "Except, it wasn't the Vashta Nerada that took over Luna, was it?" He started nodding, "Yeah, yes! you didn't fail to tame the Vashta Nerada, you succeeded! Oh yeah, it worked! it worked TOO well, didn't it?"
Princess Celestia said nothing.
"It wasn't the Vashta Nerada that took over Luna, it was something else, something that took advantage of the newly tamed swarm, Nightmare Moon, wasn't it?" The Doctor asked, "Yes, Nightmare Moon took over the Vashta Nerada, in turn taking control of Luna, that's what happened, wasn't it?"
Princess Celestia sighed, "You're as clever as ever, Doctor."
"Oh, but I'm not done," The Doctor said, "I'm on a roll now."
Princess Celestia was puzzled, and slightly scared.
"Rosebud," The Doctor said, turning towards his companion, "Taming the Vashta Nerada was supposed to make Luna a much more powerful magician, that was the purpose of the experiment. But why would an Alicorn need to be more powerful?"
Rosebud shook her head, "I don't know,"
"I don't either," The Doctor said, turning back to face the princess, "Unless, she's not an Alicorn, is she?"
"Stop it," Princess Celestia demanded.
"That's it!" The Doctor said loudly, as it clicked in his mind, "You never had a sister, did you? You're the last of the Alicorns, and you alone were in charge of raising the sun and moon, every day and night, never a moment's rest." He held up a hoof to illustrate his next point, "You were tired and weak, you couldn't do it all on your own, so what do you do? You find the most powerful unicorn baby you can, take her from her parents, give her a set of wings, trick her into thinking she's an alicorn, and your sister, and you put her in charge of the night. a small job, really, perfect for her. it would give you a break, and you wouldn't seem so alone anymore."
"Stop it!" Princess Celestia demanded loudly, frantic.
"But even though she was the most powerful unicorn in Equestria, she wasn't powerful enough, was she?" The Doctor asked, "Raising the moon every night? child's play for any Alicorn, but it was still too hard of a job for Luna, isn't that right?"
Princess Celestia said nothing, but she was trembling.
"The answer seemed obvious," The Doctor explained, "Tame the Vashta Nerada, put them under Luna's control. A whole swarm of invisible aliens solely under her command? She would have appeared to be the most powerful unicorn in existence! But then, Nightmare Moon came," The Doctor continued, "she took advantage of the tamed Vashta Nerada, took over Luna's body and mind, and tried to take over Equestria, all the while convincing the part of Luna that was left in her mind that it was so the night could last forever, so she could be in charge. So what do you do? Banish Luna to the moon and send me up there to clean up the mess."
Princess Celestia hung her head in shame.
"I succeeded, of course," The Doctor said, "All that's left to do now is blast Nightmare Moon with the Elements, and it'll all be over and done with. But..." The Doctor interjected, "I've got one more question for you,"
"What now?" The Princess asked, trying to keep from tearing up.
"Nightmare Moon took over Luna's body with a psychic signal emanating from this era of time," The Doctor explained, "So who is it, really?"
The Princess was silent. she shook her head.
The Doctor took a step closer, and asked forcefully, "Celestia, who is Nightmare Moon?"
Princess Celestia hung her head.
The Doctor took a step back, "alright, I see how it is," he turned around and began walking away, "If you ever feel like potentially saving lives, give me a call." and he walked away, gesturing for Rosebud to follow.
Rosebud looked back at the shamed princess once, then followed the Doctor.
"You're wrong about one thing, Doctor." Celestia said suddenly. The Doctor turned towards her curiously, and she said, "Luna is my sister."
The Doctor paused, then said, "Not in blood," and left the throne room.
