"Ugh... where am I?" my doppelganger groaned, shifting inside her compartment. I call it a 'compartment' because of the fact that it's literally a storage box I had made from sticks and leaves. More of a nest though, now that I think of it.
I stepped up slowly to the other Twilight, who was bound by woven grass ropes. In addition to that, I had fitted a magic inhibitor ring over her horn to prevent any spellcasting.
"But where did you get the ring?" you may ask. Let's just say that in the miniscule amount of time I had spent setting up this cave, I had also decided to construct a simple forge.
Now, enough with that. I've got some interrogating to do.
"Hey, Twilight."
The other Twilight didn't open her eyes.
"Who... who are you?"
"Hard to say," I murmured as I lifted the nest/box up. I needed some light, so naturally, carrying the other Twilight into the sunlight outside would be my first choice.
Finally, she opened her eyes, fixing them on me.
"And what are you?!" she cried out in horror, flailing against the bindings.
I shrugged. "That's what I was about to ask you, Twilight."
"Wait... you know... my name?"
I replied once again with another shrug. "Hey, don't blame me for having the same name as you. I'm Twilight Sparkle."
The vaguely horse-shaped blob of flesh I called a pony simply quivered in my presence. It was already clear that she was scared, since... y'know, being abducted out of nowhere is obviously scary. And on top of that there's also the coincidence of naming... so, yeah. She's clearly terrified.
"Are you... me?"
Dangit, I thought these ponies were intelligent! "Of course I'm not you, just look at me! How could we possibly be even the slightest hint of being the same pony?!"
The mare sat in the box, her jaw moving up and down without a word. I'm pretty sure that this is the reason why recorded history hasn't begun yet. Either way, no matter what the average IQ level of these ponies are, I'll still need their help to get back.
And then, a memory flashed across my eyes. Yesterday. When I first saw the mare.
"Though, you have a slight possibility that you might be my mother, Twilight."
All I got in reply was a THUMP as the mare promptly fainted.
I'm starting to doubt the ability of these ponies to handle anything more than magic kindergarten-level things.
