The Weeping Gardens

"Okay, Mares! Lock up the Master in the little cells. Down the hall, take a right at the pool, and then head down the stairs." The Doctor says to Twilight, who picked up the Master yet again, and then walked him in the direction the Doctor had said. "Okay! Present day Ponyville!" The Doctor pulls a lever, and the TARDIS makes the RRRR sound.

"Doctor, there's something you're not telling me."

The Doctor tenses. "...."

"What is it, Doctor?"

"....."

"Doctor."

"I...."

"What?"

"... Remember when we celebrated your fiftieth travel in the TARDIS, and I said that I wouldn't stay for long?"

"Yeah... that was two years ago!"

The Doctor lays a hand on the glass tube going up to the ceiling of the TARDIS. "I'll have to go home, soon. I can't stay for long. The Void is closing, yet getting bigger at the same time. It could cause the implosion of the Multiverse. Every single Universe, up in flames, then gone, just like that." The Doctor snaps his fingers, accidentally causing the TARDIS doors to open. "Don't look out there!!" The Doctor rushes over to the doors and closes them before anyone would be able to look into the Time Vortex.

"You can't go home! All those aliens threatening to destroy worlds! What about them?!"

"... If I could stay, I would, Derpy. But I can't. The whole of reality would implode. As for the aliens... Hm... I have an Idea, but it'll have to wait. As for now, we need to cause that Paradox. Effectively erasing the Weeping Angels and this one particular adventure."

"So... what was the point of all of that freaking out over my 'death'?"

" You're my friend, Derpy. You're my best friend. Whenever someone travels with me, if they don't leave the TARDIS sooner or later, they die. And I end up standing over their graves while a war goes on in the Universe. People die for me almost every time, Derpy. I didn't want that to happen to you."

"This has happened before, hasn't it?"

The Doctor stops again, and presses a few buttons on the console, and a screen extends from the side of it, and shows video footage of a red-haired human, with a short-haired blonde man. "Meet Amy Pond and Rory Williams. My previous Companions before you.

"We faced a race called the Silence, the Daleks, the End of The World, and rebooted it! And then... The Weeping Angels... They had to be killed, so they caused a Paradox, and killed all but one. Rory was sent back in time by that one, so Amy followed suit. I lost them."

The Doctor goes silent. "Anyway... Equestria..."  The Doctor says as Twilight walks in.

"Did I miss something?"
