Return of the Master

Colgate lead the Doctor a short distance from the library, where he saw charred ponies, dead or badly injured. “The Master will pay for this...” The Doctor growled. He looked to Colgate.

“Why’re you looking at me like that?”

“N-no reason... It’s just that... you seem so familiar...”

“What? How?”

Colgate’s eyes narrowed. “They way you walk... Talk.... the bowtie....”

“Yes, bowties are cool, but what do you mean I seem familiar? You can’t have seen me around, I’m not from here!”

“Who was that pony? The one who tried to kill me?”

“Him? He’s the Master. An old friend.”

“But- he looks so much like you...”

The Doctor shook his head. “There is no time for this. We’ve got ponies to help.”

He walked ahead of Colgate, and ended up in front of the burned remains of Sugar Cube Corner. Laying in front of the building were two fully grown ponies, and mare and a stallion.

“The Master committed genocide today. He will pay, I swear it.” The Doctor said, seemingly talking to the charred bodies. “Colgate, look around for survivors. I’ll start identifying the bodies.”

The Doctor walked away from the Cakes, and walked over to a bundle of ponies who had been shot through their torsos. “Raindrops... Cheerilee... Fancy Pants? What was he doing here? And.... Who’s this then?” The stallion, who was only chipped by whatever- presumably the Master’s laser screwdriver- hit him. This stallion had a deep blue coat with an even darker blue mane. He was wearing a jacket, one that the Doctor had never seen in Equestria before. His cutie mark was a constellation of stars.

“Did... Did you know him?” Colgate asked as she walked up to the Doctor. He had his head hung.

“I could have prevented this... All of it.... Had I just stayed away from my TARDIS after the Weeping Angels were done for, none of this would be happening...”

“What are you talking about? TARDIS? Weeping Angels? You do realize I’ve never met you before today.”

The Doctor turn around on the spot, looking at what remained of the town. Most of the fires had burned themselves out and there was no moon out tonight to illuminate what little was still standing.

See what happens. Everywhere you go, no matter how hard you try to save people, death always awaits them. Why don't you jus-

"GASP! Cough! Cough!"

The Doctor turned back to the dead ponies he was standing next to, to see the blue pony struggling to stand up as bodies slid off him.

"What?"

“What? How did I get here- Where’re my hands?!  Gwen? Is this some kind of prank?!”

The Doctor looked at the blue pony as he slowly got up, and looked around.  His eyes soon settled on the Doctor.

“Hello, there. I’m Captain Jack Harkness.” Jack said, with a sly grin etched upon his face.

Derpy looked at the new pony in confusion. So there was somepony else who had access to this bunker.... and could get out.

“Hello, there.” The Pony said.

Derpy’s face was a mix of happiness and confusion. Over noted by seeing another pony, but has no idea how this could be possible. “H-hello... What are you doing here?”

“I could be asking you the same thing.”

“I was kinda... brought down here by a... an acquaintance.”

“Well... I come down here with various artwork from all over Equestria,  decorate and maintain the place and have turned it into my personal collection. It has become a bit of a hobby and takes up much of the time I am not working.”

“Oh? So, you’re the reason there’s a painting of Shining Armor and Princess Cadence, even though this bunker’s been abandoned for centuries?”

“Yes, but I guess you could say that it is not abandoned any more. I stumbled upon this place one day when I was do field research. I decided to go deeper into the Everfree than anypony has been before, and ended up here. Though it's intriguing that not even the Canterlot Archives have any information on this place.

"But enough about that, we haven't properly introduced. What's your name then, Miss?"

“I’m Ditzy Doo, though... Some call me Derpy.”

“Derpy? Well, that’s not a very nice name.”

“I don’t mind it. In fact, my best friend calls me Derpy, but he doesn’t mean it like what other ponies do. He’s a nice stallion.”

“Well it is my pleasure Derpy, I am Sky Dancer.”

"Nice to meet you Sky Dancer.”

“Jack?!”

“Yeah, that’s my name. And, who, is that?” Jack looked behind the Doctor, directly at Colgate and grinned.

“Th-that’s my friend, Colgate.”

“Colgate, eh? Where I’m from, that’s the name of a toothpaste.”

Colgate took a step forward. “I’m a dentist, that’s probably why. And, might I ask, who are you?!”

“I’ve already said. I’m Captain Jack Harkness."

"Jack Harkness. You haven't changed a bit! Well.... Aside from the whole pony bit, but I'm going through the same thing..."

"Who are you? Have we met?"

"Take a good look, Jack. For some reason, this universe based the pony body off my previous form back home.... My Tenth, to be precise."

"Doctor..."

"'Ello, Jack."

"So, Ditzy, how long have you been here?" Sky Dancer asked the grey pegasus, who sighed and layed on her side on the couch, taking a bite out of the muffin she had made from the forge.

"I don't know. I haven't even seen the sunlight in days... Possibly weeks, or even a month! The Master has some kind of plan for me... I overheard him talking about that one night. He's crazy talking to himself."

"Hold on... The Master? What, do you two have some kind of role play relationship?"

"What? No! He.... Kidnapped me, one day after my friends and I came back to Ponyville."

"He kidnapped you?! What, why?!"

"I don't really know... But I am sure that my friends will show up and save me."

A silence fell between the two. Derpy looked at her muffin with sadness. Sky Dancer placed a hoof on her shoulder and looked at her.

"I'm your friend, right?" Sky Dancer asked.

She sat up and look back."Yeah..."

"And, I know the way out."

She began to smile. "You don't mean-"

Sky Dancer smiled back. "Yes I do. Ditzy Doo, you're breaking outta here."
