Underneath the streets of Canterlot, Equestria- Gaia-60192

Princess Twilight Sparkle of Gaia-Prime, Pinkie Pie of Gaia-996, and The Doctor follows the Applejack of her Gaia through the sewers of Canterlot. Twilight noticed that this Applejack has a scowl on her face. The orange earth pony mare sighed, as they stop near a entrance, then the former farmmare begins to enter the code; thus opening the gate. The four ponies enter what appears to be a base, filled with other ponies. The Doctor noticed they consisted mostly of earth ponies, some pegasi, and a few unicorns; by the looks of it, the group is a small rebellion.

"Welcome to headquarters," Applejack introduced, as the other ponies in the base waved towards the newcomers.

"Pinkie Pie?!" A familiar voice rings out.

Galloping towards the four, was a wheat colored unicorn, with an orange mane, and blue eyes. This mare was familiar to Pinkie, as she welcomes her with open hooves.

"Pumpkin!?" Pinkie greets the filly, hugging her tightly.

"Pinkie Pie," she greets tearfully. "is it really you?"

"Sorry, surgarcube," Applejack sighs sadly. "this ain't the Pinkie we know."

The young Pumpkin glances at the mare, still hugging the pink mare. Twilight trots to Applejack, biting her bottom lip.

"Applejack," she inquires. "what happened here? Why is there oppressive soldiers in Equestria?"

"Because of you," she answers. "well, this world's version of you."

"Explain," the Doctor said, trotting around the base.

"Well," Applejack sighs. "five years ago, Discord escaped, causing havoc all over Equestria. This time, he made it personal for Twi." The alicorn gulps, not liking what she was gonna say next. "He tricked Twilight into thinkin' she was fighting Chrysalis, but in reality, she was fighting Celestia."

"Oh no," Pinkie covers her muzzle.

"No," Twilight's violet eyes widen in shock.

"It gets worst," Applejack removes her stetson. "when Celestia died, most of Canterlot died with her, including Twi's parents, brother, and her husband."

The alicorn from Gaia-Prime stood in shock and awe at the events that this world's Applejack described. She shakes her head in disbelief, not wanting to believe what she was hearing.

"In her grief," Pumpkin sighs. "she killed Discord, and seized control of Gaia; becoming judge, jury, and executor."

"And anypony who opposed her," the Doctor says, only guessing the worsts.

"She killed them," the alicorn of Gaia-Prime answers, Applejack sadly nods.

"Including my Pinkie," Applejack's eyes begin to fill with tears. "most of my family, Vinyl, Derpy, and most of the old Royal Gaurd. Rainbow, Rarity, Flutters, they're actually backing up Twi's insanity out of fear or they actually believe in this crap!"

The Doctor glances at the rebels, their faces filled with sorrow and lost. He has seen his share of awful wars, even participated in them, but this; these ponies were looked liked they are on their last rope. He then noticed a wedding ring on this Applejack's ankle, as she sobs into her stetson. He trots to the crying mare, placing a hoof on her.

"She took your husband," he inquires. "didn't she?"

"Ah," she sniffs. "Ah know he's alive. He was sent on a run to get supplies, and we-- Oh, dear Faust!" She collapsed back onto her hat. "This' my Faustdamned fault! Oh Caramel! My Caramel!!"

"Applejack," Twilight speaks up. "I know I'm not your Twilight, but this' a promise; We're gonna free your husband, and this world."

"Y-Ya," she glances at the alicorn. "ya really mean that?"

"We understand the risks," the Doctor said. "To retrieve the TARDIS, we need to stop this world's Twilight."

The ponies of the Insurgency glanced at the outworlders, with worried glances. Trixie gallops to the them, with a raised brow. "Are you sure of this? Because we have little resources to pull this off, and all of our previous plans ended in many of our forces dying!"

"Trixie," Twilight trots to the blue unicorn. "we need to do this together. Even if we aren't from this world, tyranny cannot go on!"

Then, a lone stallion, Soarin, begins clapping his hooves. Then, the rest of the rebels begins to clap as well, including to cheer in agreement. Applejack lifts glances at her brethren, a smile spread on her face. She turns to the alicorn, then gallops to hug her. "Ah know this' ain't accurate," she pulls away, glancing at the lavender mare. "But it's good to have ya back, surgarcube."

"Well," she smiled awkwardly, "good to be back."

"Guys!!" Soarin calls out, pointing to the screen, "There's something you need to see."

The insurgency glanced at the screen, which shows this world's Twilight Sparkle, her eyes filled with malice. The alicorn from Gaia-Prime felt some fear as she saw her counterpart, who bears dark violet armor, and a helmet, almost resembling Nightmare Moon. She glanced at the camera, as she begins her speech.

"Five years ago," she spoke. "a tragedy struck our great kingdom. In his grief, he became a agent of chaos, associating himself with the rebel Applejack. He undermined the our order, aiding fugitives from justice, but no longer!"

"I don't like this," the Doctor breathed.

"At 7:00 pm, on the balcony of New Canterlot castle, Caramel of the Insurgency will be executed."

The rebels stare in shock, as the outworld Twilight covers her mouth. The Doctor grits his teeth, as Applejack furrows her brows into a scowl. Pinkie held Pumpkin close, as tears pour from her eyes.

"May Faust have mercy on his soul."
