The Doctor has landed in a new world and discovered he cannot leave.

Chapter 2: The Impossible

The Doctor just couldn't understand it, it was impossible that Tardis was saying that it was completely fine yet it would not move, he had a horrible feeling of what it could be but he was hoping that he somehow missed something but for the sixth time it all read that the Tardis was in (relatively) good condition. He knew that there was only one possible explanation, the Tardis was literally refusing to leave the planet.

"Why? Why do you want to stay? Have I not caused enough damage!"

After the Doctor had finished his screaming he let out a heavy sigh, he decided to look at the options before him, he had two in reality the first option was to stay in here and just hope that the Tardis would come to its senses and allow him to leave or walk out of the Tardis and face the hyperactive music that was just outside his door, he was willing to bet she was still breathing heavily outside his door eager to get in.

He gave in quickly knowing he couldn't win in any of these situations and walked slowly to the Tardis door.

He put the key in to unlock it, but before he did he listened closely to the frame, he could hear desperate, heavy breathing, as slowly as he could he turned the keyhole still putting his ear to the door to hear the breathing getting faster the more the key turned inside the door, he heard the click signifying that the door was indeed unlocked and he breathed one last heavy sigh preparing himself for what was about to come and as soon as he opened the Tardis door a crack a purple pony came shooting through the door at what the Doctor could only describe as near light speed and head-butted the central console knocking herself unconscious.

Twilight Sparkle felt like her head had just been kicked in multiple times by princess Celestia and Princess Luna and then the two of them threw her into the wall with their magic several times more, she was having a lot of trouble lifting her head above the cold ground she was now lying on, it felt like she was lying on a combination of glass and metal.

She dared to at least open her eyes to what was above her, there she saw the blurry image of a light pink creature, when the creature talked to her, its voice was like it was calling out to her at the end of a long tunnel.

"Twilight! Can you hear me?"

She wanted to call back out to the creature but the words just didn't seem to be able to pass her lips so her mouth just hung there open, it called out to her again "Twilight your inside the Tardis I need you to respond to me."

It all suddenly came back to her in one reflective motion; the Doctor, Timelord, his knowledge of her, and the Tardis, she paused on that last part.

"Wait a second…I'm…in the Tardis?"

Her vision suddenly became more clear the more she focused on her surroundings, she was in a large room which had some sort of centre with lots of buttons and levers and she also noted the weird statues that seemed to surround the room, it dawned on her at this moment that this was impossible as the room she was in was very large while the Tardis was just a little blue box.

She stood up surprisingly fast, her intellectual mind was having trouble conceiving the room that she was now in was the same as the small box, she paced slowly away from a crouching Doctor to the entrance of the Tardis "What…how…this is…I can't…what?"

She suddenly ran straight out of the door behind her and looked back to see she was standing outside the same box that was in the middle of her library, Twilight felt like she was having a mental breakdown, one similar to the time she freaked over being tardy with a letter to the Princess, what was happening was impossible "What spell can do this!"

She ran around the box to see if there was some kind of trick to it but found nothing and then she ran back inside to confirm that she was not insane and tried to blurt out "It's…"

The Doctor cut her off with a small grin on his face.

"I know."

"But its…"

"I know."

"It can't…"

"I know."

Suddenly Twilight screamed in what looked like she had finally snapped.

"ITS BIGGER ON THE INSIDE THAN THE OUTSIDE!"

The Doctor just stood there for a moment, unsure on what to say but could only find two words to sum up the situation.

"… I know."

To the Doctors surprise Twilight showed an angry expression on her face, as if she was about to lunge at him but all she seemed to do was make her horn light up a purple colour, she pointed her horn at the Doctor and started to pace towards him.

"This is impossible, nopony has this kind of magic so tell me the truth, who are you and how did you know who I am?"

The Doctor raised his hands to show no hostility towards her however Twilight did not power down her horn.

"Miss Sparkle please I know this is hard to explain but…"

Suddenly the doctors monitors started to pick up, a blue light stated to scan Twilight's horn and she tried to dodge out of the way to no avail, new statistics appeared to the Doctor on the monitor closest to him, the Doctor forgot about Twilight and looked over the data that had been given to him, "Ah now this explains a lot, my Tardis has just identified the mysterious energy that brought me here, although it isn't from you it shows that the energy was…magic."

The Doctor had paused on that last part of the sentence, he didn't believe in magic however in the show magic did exist thus in this reality Unicorns (which also shouldn't exist) like Twilight could perform magic, the data also showed it did not completely match Twilight signifying that she was not the one who brought him here.

He scanned the room for Twilight who had taken cover behind the sofa of the Tardis, she peeked her head over the top.

"What…What was that?"

"Sorry about that, my Tardis took the liberty of scanning you as it managed to recognise the energy signature coming from your horn as the same that brought me here… magic."

The Doctor looked to her again and she seemed to be gaining a bit more courage as she was starting to step out from behind the coach.

"Is this some kind of magic?"

"No it's the chameleon circuit."

"And what is that exactly?"

"It's a device within the Tardis to help it camouflage around its surroundings, it bends space and time as it's in its own dimension to make it appear smaller on the outside and it constantly changes its appearance to fit its surroundings, for example if it went into an alleyway it would appear as a rubbish bin but the circuit broke years ago and its stuck as a police telephone box and since I like the design I've just never fixed it."

Twilight had been absorbed and entranced by every word that the Doctor was speaking, it was all so alien to her yet in some weird way it all made sense, she did have experience in time travel and she had theorised with enough magic she could bend space around herself, one thing stuck at her however.

"What's a police telephone box?"

"Oh it was something people from my reality used around the 1920's to 50's to lock criminals up to a police officer could arrive."

Again in some weird way Twilight Sparkle understood what he meant.

"So you're from another planet?"

"Well not exactly, I'm from another reality where there is no magic and…"

Twilight cut him off before he could continue.

"Wait sorry did you just say no magic."

"Yes there's no such thing as magic in my universe, we mainly use technology like the Tardis but less impressive."

"What about ponies?"

"Yes there are ponies in my reality but they're not exactly the same and out of kindness I think we should leave it at that."

Twilight had calmed down significantly now, she took one more look round her surroundings making sure that she was not daydreaming, her head started to hurt slightly.

"Ugh…I can't stay in this room its making my head hurt."

The Doctor knew that he would probably be here for a while so he took this opportunity to make peace with his new neighbour.

"So then why don't we have ourselves a nice cup of tea, that helps me all the time…well mainly during regenerations but it clears the synapsis."

Twilight nodded, "Yeah ok, that's a good idea."

The two walked out of Tardis together with the Doctor preparing himself to tell all.

---

The Doctor had been introduced to Spike, the initial meeting was much the same as Twilight's as it involved a lot of confusion and a lot of questions but he too was soon calmed down also and he proceeded to make tea.

They sat there exchanging facts about each other's universes, Twilight had mentioned that she didn't think aliens existed but came to the conclusion that it may indeed be possible after meeting the Doctor, the Doctor talked about Gallifrey although a first he was reluctant to do so, he left out the fact that he is the only Timelord left in his universe, Twilight was in the middle of telling him an interesting story about Princess Celestia the co-ruler of Equestria.

"…So in the end it turned out it wasn't a double ganger and the truth was that the Princess genuinely didn't like tea, but because of how quickly tea stocks were crashing and how many Ponies were upset by this revelation, especially the royal tea pony we decided to cover it up."

The Doctor couldn't remember an episode like that in the show, he theorised that worlds like Twilight's had adventures and stories that were not shown on TV, but the Doctor wondered what happened when the show was cancelled, did the world cease to exist or did it just carry on, the Doctor's train of thought was interrupted by a question from Twilight, "Doctor I still have a question for you, how did you know who I was?"

The Doctor wasn't really sure on how to answer that question, Twilight had been told a lot today and experienced things that she didn't think were possible and the Doctor didn't know how much more her fragile mind could possibly take, how could he break it to her that the only reason her entire world exists is because of a children's TV show and she probably wouldn't even know what that is, he decided to make up something.

"Well… um… I can… read minds."

He didn't say it with full confidence but realised he had something on him that could back it up, "In fact this piece of paper proves my credentials as a mind reader."

He pulled out his trusty psychic paper which had gotten him out of many troubles in the past and shoved it in front of her; Twilight read it aloud.

"The Doctor, Professional mind reader, cleared on licence to work on Gallifrey."

The Doctor quickly placed it back in his pocket before Twilight could get a closer look and figure out that it was just a plain piece of paper, he quickly took another sip of his tea and continued on.

"Yeah sorry about reading your mind without your permission, I needed to know where I was and I just so happened to come across your name."

The Doctor gave a smile as it appeared that his lie had worked, Twilight looked in amazement that the Doctor had such an ability.

"That is amazing, but I must respectfully ask that you no longer do that as privacy should be respected for everypony."

The Doctor put on a serious look trying to cloak the smile that he wanted to show.

"Alright no more, I won't read anyone else's mind."

"Actually your mind reading powers are quite fascinating is there anything else interesting about your biology."

At this point the Doctor thought that there couldn't really be any more harm done by telling her more about himself, mainly as twilight wasn't really a threat to him.

"Well actually I have two hearts."

"Wow, really?"

"Yeah I don't really know how anyone can really survive with a single heart personally, one of my hearts stopped working once and I could barely function at all."

"Anything else?"

The Doctor thought for a moment.

"Well I guess I could tell you about how I regen…"

The Doctor was cut off by Spike who was now placing two sandwiches in front of them, there was something a little off about them to the Doctor, "What are these?"

Spike looked up at him with a tired expression on his face, not only had he cleaned up the mess the Tardis had made when it materialised inside the library but he also had to make them these.

"Their Dandelion sandwiches, Twilight told me to make you one because she thought you might be hungry."

Twilight stepped in, "They're my favourite and Spike can make a pretty good meal for a pony."

To the Doctor the key word there was 'pony' and as the Doctor looked at the food before him he wasn't sure if he should eat it, there were grass blades sticking out the sides of the sandwich and what looked like the head of a dandelion sticking out another, he had eaten some of the finest cuisine the galaxy had to offer from earth to delta-5 but he had never been offered a dandelion sandwich before.

Against his better judgement he took a bite and to his amazement he liked it.

"mmm now this is good, I mean it's not as good as jellybabies but man this is one of the best sandwiches I've eaten and I'm over 900 years old."

"What are Jellybabies?"

"Their sweets but probably not the kind you have in Ponyville, let me guess you have a sweet called jellyfoals."

"Yeah that's right."

"Same basic thing, I loved them in my fourth form and practically offered everyone I met one, but it always seemed to get mixed results."

Twilight simply smiled, and continued eating, she wasn't sure what he meant by fourth form but did not question it as her mind had been practically blown enough today, but then an idea came in to her head.

"You know you said your Tardis won't leave and it was brought here by magic."

The Doctor's mouth was full of food but he managed to get out a muffled Yes, "Well it might be being kept here by a spell so maybe we should gather my friends and possibly seek out who could have grounded the Tardis."

The Doctor didn't understand magic fully so this was a potential theory to why the Tardis was refusing to leave and then it occurred to him.

"Wait does that mean that I get to meet the elements of Harmony?"

"Let me guess you saw that in my mind to" she let out a small giggle "It will be interesting to see how they will react to you but yeah I think that would be a good idea."

The Doctor gave the biggest grin he could and stood up as quick as a flash, he shoved the rest of his sandwich in his mouth and drank the last of his tea, he gulped it all down in one flowing motion and said "Twilight Sparkle it would be my honour to accompany you to town today."

The Doctor realised at that moment that he had not felt this happy or excited in a very, very long time.
