Creepy town

Roughly a year since that happened, Twilight, who was now an alicorn, and Applejack, who was still an apple farmer, were going around the barn at Applejack's farm, talking about apples and water.

Suddenly, Twilight glitched. She froze. In the middle of sentence she was telling.

A second later, Applejack turned. Twilight had a frozen rolling eyes expression on her face. "Are you alright, sugarcube?" - Applejack asked.

No response. But a minute later, her horn lit up, and begin casting a spell, which continued on for a minute, and then another minute for another minute for another spell. And after that, she started moving again, but fell on the ground, utterly tired.

"Do you need help?" - Applejack asked. "No", a quiet answer came instantly.

Twilight faded into unconsciousness.

And then Applejack decided to carry her. No one from Apple family had cellphones, so her destination would be either Spike's Library, or the hospital. And she chose the former, realizing how light Twilight was. No normal pony would be that light. Examining her, she found stitches on her head and belly.

Then she realized, that Twilight Sparkle might be a zombie. Only a few ponies in Ponyville still didn't believe in them, and Apple Family wasn't among them. Last time, zombie ponies all went into the orchard to pick apples, apple zombies they were, and Applejack herself had to defend the buildings.

They began going to town, and then through town, where Rainbow Dash noticed them from the sky. Applejack was glad she did. "What's with Twilight? Do you need help?" - Rainbow shouted.

"No!" - was the answer. "No! Yes!" - was the correction. "Could you help carry Twi somewhere, I rackon she might've become a zombie."

"Again? No" - Dash made a loop in the air, preparing to carry, " where does it come from?" She landed. "Seems normal..." - she noted. "Let's go."

On their way to Spike, Twilight woke up. She thought for a minute, what to do, while they still carried her. "*cough* How long I was out?" - she spoke slyly.

"Half hour," - Applejack said simply. "Can I stand up?" - she asked. "No", - Applejack replied coldly. Twilight was quiet in three next minutes.

"We'll cure you," - Applejack said when they came to the tree. "I don't need cure!" "You don't?"

"I don't"

"Then explain, what are the stitches on your body!" - angry Applejack said.

Then Twilight went really sad.

"I'll explain."

"This is my experiment. When I became an alicorn, I got an overwhelming magic boost that was making me nervous for weeks after. Magic was replacing my other senses. Sometimes even, when waking up, I casted a vision spell instead of opening my eyes! Later, when I mostly understood how much different I was, ...I tried to find a way to fix the problem without restraining my power, which was certainly a bad solution. It wouldn't even work. And for fixing that, I would need to understand what those other senses were. That proved to be useless, too. I would only drive myself insane. I gave up. I have accepted that I was Magic, not so much a pony, and the source of my life force was my horn, and my magical trail. I Realized that everything I would need to talk with you, was my interface, so to speak, a visual representation of my body; the rest I would do with just magic. My real body, my heart and brain are home, magically connected to this body. What you see now is part of my clone, my magical interface."
