An Old Whooves Tale.

In the TARDIS the Doctor was furious with Derpy. “What have I told you so many times before? That no being should have foreknowledge of their own personal future!”

“She deserved to be consoled Doctor! You didn’t once say you were sorry you just lectured her!”

“I was preparing her! Consoling is a temporary pep up! For what she’s faced with she’s going to need a lot more than pep, she is going to need raw strength by her side! Yes Derpy we already know how the story ends, but she does not and no matter what she will go through a thousand years of pain and guilt!”

The Doctor yelled this and went back to the control panel to start flipping levers and knobs angrily. Derpy stood there with her head down feeling like a child who had just got caught with her hand in the cookie jar. Then she finally asked,

“Do you know what that feels like Doctor?”

“What?” The Doctor asked not taking his eyes off his controls.

“I mean have you felt the same thing that Princess Celestia is going to feel? The years and years of guilt?” The Doctor stopped working at the control panel and looked down for a second.

“Derpy please we should-”

“Do you Doctor?” she interrupted him. The Doctor let out a sigh and walked away from the controls to face Derpy. “Doctor I could see something in your eyes that night, something… painful. Every once in awhile I can see little flashes of it too. What is it? The Doctor paused for a moment looking away then facing Derpy again.

“I have been alive for a very long time, much longer than Celestia has, and for a good majority of that time I’ve been alone.” There was a pause and then Derpy asked.

“Why are you the last of the Time Lords Doctor?”

The Doctor looked away and paced around the room for a while.  “I want to know why you’ve been alone.” The Doctor gave Derpy a hard look then approached her again.

“Okay here it is. A very long time ago there was a war. A great war between my race and a race of monstrous creatures; I call it the Last Great Time War. It raged on for years and years, until one day I found a way to stop it. However to stop the war it would mean that my entire race and the enemy’s race were to be pulled out of existence."

"I ended up choosing to end the war. The simple fact I’m alive is what guilt’s me every moment of my life. So yes, I understand what Celestia will go through, being responsible for imprisoning the pony closest to her. Yet unlike her, I know I shall never see my people again.”

The Doctor walked away and started to throw switches and levers again in the TARDIS. Derpy walked around the center of the TARDIS and looked up at the core, which was shining brightly and whirring quietly.

“Doctor?”

“Yep?” He said poking his head around the core allowing his usual pep to enter back into his system.

“Thank you.” The Doctor looked confused and asked,

“For what?”

“You do a lot for everypony and they don’t even realize it, but I just wanted to let you know that we’re all grateful.” The Doctor cracked a smile and dipped back beneath the controls.

“Oh it’s all in a days work Ms. Hooves. NOW! I think I’m in the mood for some deep fried butter squares how about you?” Derpy laughed and stood next to him.

“Honestly I’d prefer a muffin!”

“Oh, well have all the deep fried muffins we can eat! With lots and lots o butter! Advante!”

“Advante!” Derpy cried

The Doctor flipped a switch and the TARDIS shook again traveling through the time stream, and both ponies smiled as they held on to the rocky ride.
