Derpy eventually got to the TARDIS. She opened up the door, and the TARDIS had been changed a side effect of the self repair, I guess

Suddenly, the figure now confirmed as the doctor walked up the tiny set of stair on the side. He had swapped his tie for a dark purple bow tie

"Why are you wearing that?"

"I like bow ties now, bow ties are cool" he let out a small smirk on his face before walking up to the control panel.

The doctor got out his sonic and waved it around a little. It was different, with copper plating, a leather grip and a green tip.

"Like my new sonic? I thought the old one was a little outdated to I threw it away and the TARDIS gave me a new one"

"Now, I fancy visiting Old Canterlot- great place it is, it looks old fashioned but it's quite nice"

Derpy was silent which was an odd thing. She's usually so energetic. But he reliased why.

"You're not too keen about my regeneration are you?"

She shakes her head. The doctor walked up to her and said quietly

"Now, I know that you're not liking this regeneration, I don't either, I've got a bad itch at the back of my head. But you need to learn to accept it"

Derpy was silent before saying "All right then, you!"

The doctor smiled "Alright then, Old Canterlot?"

"Old Canterlot"

The doctor was about to pull the lever but before doing that he said "new regeneration calls for new catchphrase...Uhhhh... Got it!"

He pulled the lever and then let put a loud shout, saying:

"GERONIMOOOOOO!!!"
