Three guards lead The Doctor and Derpy into the dungeon and put them into separate cells. On the way they passed a young guard who looked like he would get lost on a straight street. “You will be held here until we can figure out what to do with you.” The apparent leader of them said, locking Derpy’s cell door, then activating the Doctor’s cell’s force field.

The Doctor was chuckling at their own predicament, “You know the reason I made us leave the girls behind because I was afraid I’d anger Lazarus and he would attack, and now we’re in prison for ‘killing’ him”.

“Why the air quotes around ‘killing’.” Derpy asked now confused.

“His survival instinct made him transform into that monstrous form of his, he survived and is probably rampaging at the base of the mountain right now. But then again he did survive this whole time by being sneaky so he might have burrowed his way into the old mines under Canterlot."

"Ok, so we tell them that and they let us free?"

"Not at all, they'd never believe us if we told them the truth. So we'll just have to find another way out of this. Do you happen to know what the punishment for murder is or was?"

"Banishment from Equestria." Derpy answered.

“Oh well that’s not that bad, as long as they send the T.A.R.D.I.S. with us.”

“Quiet in there” the watch guard said walking by them, “You two are facing some serious charges, you know that the penalty for killing a Prince?”

“Banishment?” Derpy suggested.

“Nope death by sending you to the sun.” The guard said a bit too cheerfully.

“Oh well, that’s nothing we'll be fine.” The Doctor said winking.

The guard didn't even notice as Derpy reached with her wing to lift the keys off his flank.

“That’s an odd way to look at the sun” The guard said not noticing what Derpy was doing.

“Of course it’s an odd way to look at it, I’m an odd pony. After all I did manage to sneak into the castle with a companion and a blue box, and then I managed to kill an old prince.”

Derpy had the key now and hid it under her pillow.

“Now can you tell me why I’m behind a force field and she’s behind bars?” The Doctor asked pointing to Derpy.

“She’s a pegasus and we don’t let them near cloud constructs” The guard explained to the Doctor, The guard walked off.

Derpy unlocked her cell and simply touched the force field in front of the Doctor and it dissolved. “Come on Doctor we need to get out of here.”

“Ok, now where do you suppose the T.A.R.D.I.S. is?” The Doctor asked looking around. “We’ll also need to find my sonic. Don’t want to spoil the time line, do we?”

The two of them simply walked out seeing how Equestria had little to no need for a large guard. They only had to duck down once to avoid the guards and that wasn’t even that hard. No the hard part of the escape was getting the sonic and Tardis.

They went to get the sonic first; it was hidden in a drawer of the watch guard’s desk. The Doctor rummaged through the drawer for anything else of use. “Look at this” The Doctor said picking up a small, smooth, and polished stone. Then, when he realized what it really was, he jumped up and dropping it.

“So you've escaped. My Queen will be angry” the guard said as he stepped into the office.

“The last time I saw your kind…”

“You committed your third mass genocide of us” The Changeling interrupted, “Have you come to finish what you started all those countless years ago.”

“No, I’m here to find my box! Now tell me where it’s hidden.”

“The Princesses have taken it themselves. I believe they are think you are the cause of a lot of trouble. This is only made more apparent when you take into account that all of ten royal guards even know about your incarnations.”

“Why are you telling us this?” Derpy asked, shivering.

“Because I’m letting you go after it. Just return the favor the next time you think of performing genocide on the changelings.” At that he stepped aside and walked on as though he was continuing his rounds.

The Doctor started rummaging through his desk again. Derpy got an agitated look at him and said, “Don't you think we should go before he changes his mind?”

"Well we could but he won't, in order for him to do that he would risk us reviling him as a changeling. Besides how else would we get his spare map." he said pulling out a rolled up piece of paper. He opened it and gave it a quick glance, "Ok the T.A.R.D.I.S. is located in a store room near the throne room." He looked up, "That's odd I would have thought that the princesses would have been smart enough to keep it out of the palace"

"Maybe that's where they store it whenever they capture you." Derpy suggested.

They went off sneakily, trying to keep from being seen. After a few near misses, they got caught by a guard, "Hey, You!" the guard started, "You’re not supposed to be here. This part of the palace is off limits to tourist, if you'll follow me I'll escort you out."

"Sure" The Doctor said giving derpy a little wink.

"So tell me soldier, how often do ponies end up getting lost in this place?"

"Not often" The soldier said quickly.

"Well then, why is the day guard patrolling the palace during the night?" The doctor asked again.

"Classified" The guard replied.

"Fine I can take a hint."

The guard stopped walking and began repeating the same word over and over, "Return."

"Come on" The Doctor whispered to Derpy.

"Shouldn't we help him?" She asked.

"No he's under the Silences control now, besides he's perfectly fine." They simply walked away from the guard. "He’ll lead us close to the T.A.R.D.I.S." the Doctor said looking at the map. "Come on"

After getting a little lost because the map was wrong they found the room that the tardis was locked in. The doctor used the sonic on the lock. He got it opened and almost immediately a loud alarm went off. "So that's why they have the T.A.R.D.I.S. so close to the throne room."

"Because the throne room is close to the barracks, and the royal chambers." Derpy finished.

"Yes exactly." He quickly open the door and Derpy ran inside.

"Halt!!!" guards shouted, running towards him.

Luna lit down on the other side of the corridor "Doctor, why!?!?"

"No time, just remember that if you meet me before I did this then you should let me go." He shouted and tried to enter the Tardis.

Luna used her magic to pull him out, "You won't be escaping your trial!" Luna shouted.

"You know while you were banished to the moon I had to deal with a nasty monster called a Dalek..."

"What's your point?" luna asked.

"I learned that the sonic can manipulate your energy manipulation, now if you don't mind I'm going to reverse the polarity, mind you not of the neutron flow" The Doctor activated his sonic and the magic around him exploded outward releasing a shock wave that knocked down the guards and caused Luna to stumble.

The Doctor was unaffected by it and ran towards the Tardis this time he made it in and ran to the main council, "Ok, I'll just drop Derpy off at her home and then I'm after the homo reptilia..."

"What?"

"Well I plan on returning home and as far as I know that is the last time he'll have a portal open." The Doctor landed the Tardis in Derpy's living room and stepped out with her, "Oh, by the way, here you go." the Doctor gave her a bank slip, Lazarus gave it to me back when we were dealing with the cybers, for the first time. If the bank still exist then you should be able to withdraw the money from this slip."

The Doctor turned, not liking long goodbyes, "Will I ever see you again" She asked.

"I may come back. Yes, I may come back. But if I don't, if I don't, do not despair for that only means I have returned home. I will always remember you and your kids, I will always remember no matter what happens, I will remember. And I hope you will as well. Now I return to my home to hear the 'River Song' with it's beautiful 'Melodies'. " He smiled and turned to the Tardis.

He didn't make it, there was a blast of electrical energy and he fell over, "Do not worry, he won't die. At least... Not yet." said a gray blue pony wearing an eyepatch with his tall pale friend behind him.

"Stormy? What's going on?! Why did you attack?"

"He attacked because he chose to, and I have lived too long to allow myself to be killed by an old employer." He said with a sinister smile.

So my muse keeps abandoning me, and well that's why it keeps taking so long in between chapters.
