The Weeping Gardens

A capsule appeared in the center of the TARDIS, glowing from the trip across the Void. "Here it is, Derpy. The thing that'll kill you. Are... Are you absolutely sure you want to do this?" Derpy nods her head, and the Doctor's heart drops. "...Well, then..."

The Doctor opens the capsule with his Sonic Screwdriver, revealing the wrist-watch like device. "Just... Be safe until I find you, okay?"

"I'll be fine, Doctor."

"You're right... Now, I just strap this on, and bada bing, I have Time Travel without the TARDIS. Let's go find an Angel..." The two ponies walk out of the TARDIS, knowing what is about to happen. "I'm sure the Angels have already replaced every single statue in Equestria. We have to make sure we spot an older you."

"What?"

"You will get sent back in time by an Angel, so we need to find an older you, see her die, so that it's a fixed point in time, and then, you have to die in the present..."

"I thought the plan was-"

"That plan won't work, I had a brain fart- Whoa!!" The TARDIS shudders and rocks, causing the Doctor and Derpy to go sprawling around on the floor. "Stop it, stop it," The Doctor runs up to the controls and pulls a lever, and the TARDIS stops. "Stop it! What was that, eh? Huh?"

"Doctor, what's going on?"

"I have absolutely no idea Derpy. Someone might'ave been sent back in time. The question is... who?" The Doctor turns to the door of the TARDIS and walks out. "Let's go, Derpy."

"Who was it? What am I missing? Somepony was sent back in time by an Angel... Who?" The Doctor pulls out his Sonic Screwdriver and scan the area, but comes up short. "Ugh... Nothing. Let's go see if we can find Twilight and her friends."

It took some time, but they eventually managed to find Twilight. "There you are, Ms. Sparkle! We've been looking everywhere for you!" The Doctor runs up to Twilight and pulls out his Screwdriver and scans her. "Definitely Twilight. Not a living plastic copy, not some... After life image, or Cyber-Pony... It's Twilight."

"What are you talking about? Of course I'm me!"

"Yes, but I had to be sure. Somepony was sent back in time, and I need to know who it was. If the Angels are in Ponyville... Celestia help us all. Whup.. Something just occurred to me. If the Angels crossed over from my Universe... did something else? I hope not, but if another me came, then we may have a better chance. Or maybe even Rose. That'll be good, too. And if Jack came here... If he was a pony... Don't let him near a bed with another mare. Or Stallion. Or griffon. Or Drag- you know what? Don't let him near a bed."

"Anyway, we need to create a Paradox, Doctor, we need to find the older me." Derpy reminds him.

"Oh, yes! Come along, mares! Oh, that reminds me of the Ponds... Well, Allons-y!"

"What?"

"It's French for 'Let's go'."

Then, the three ponies walked around Ponyville, looking for the other Bearers of Harmony, hoping for a chance to beat the Weeping Angels. "The Elements are unnecessary for this situation. I would, however, like you guys to tell ponies that it was you who defeated the Angels. My name kinda... attracts baddies if it goes down in History."

At the Royal Sister's throne room, Princess Celestia was sitting next to her sister, who were using magic to watch over the residents of Equestria. Unbeknownst to them, they were in great danger. As nopony was looking at the statues outside, the Weeping Angels were moving freely through the air, unable to be seen even by magic.

The Doctor did not know the Angels' plan, so I will not tell you, but I'm sure you know already. The Guards outside the door were prepared for anything, standing confidently, sworn to protect the land of Equestria with their lives. The Guards barely ever blinked, but they did when they had to.

And so, they happen to do so in perfect union.

When they open their eyes, five statues appear in front of them, two of them covering their eyes as if crying, and the other three with demonic appearances, with sharp eyes and claws prepared to gore. "Ah! Halt! Who are you?!"

The Guards start to back away, not taking their eyes off the statues, and act that saves the two's lives. They open the doors and back into the Royal Throne Room, and close the doors, still pointing their spears. "Princesses! Stay put!" One of the Guards yell.

"What is the meaning of this?" Celestia asks.

"Moving statues! Just as the Lavender Stallion said!"

"Sister, what is the Guard talking about?"

"... Call the Doctor."

"My Princess, are you sure? Has it come down to this?!"

"Luna... My dear Sister... Call the Elements."

"Yes, my Sister..." Luna flies through a window towards Ponyville, with the knowledge to save Equestria...
