The Doctor woke up, feeling a disturbance in the police box.
"She's okay."
"Who's...okay?" grunted the caretaker as she struggled to stand up.
"The TARDIS."
"Who?" asked the speedster, whilst rubbing her head.
"Time And Relative Dimension In Space. My granddaughter coined the term, thank her very much." The Doctor said. "This baby travels through time and space, thanks to her I have saved the universe a lot of times."
Rainbow Dash, with a nervous expression on her face, asked, "Are we travelling through time and space now?"
Fluttershy, who managed to read the TARDIS' patterns, answered, "Yes, Dashy."
The TARDIS changed its course. The interior shook left and right. The Doctor, seeing the newcomers struggling, merely sat back and waved his sonic screwdriver, while whispering, "Expelliarmus. Peh."
Discord, who managed to get used to the TARDIS, accompanied the Doctor.
The TARDIS stabilized, with Fluttershy on top of Rainbow Dash in a sexually suggestive position.
"Are those two...together?" the Doctor asked.
Dicscord nodded.
"Oh...not this again. Your kind is asexual as well?" The Doctor asked.
"W-W-What?" Discord asked.
"Oh. You're not." the Doctor calmed a bit. He mused and made a tiny nudge with the TARDIS' control panel. A ripple in spacetime shook the blue box, and made the two pegasi kiss.
"Rainbow and--what's her name?"
"Futtershy." said the former chaos lord to the Gallifreyan.
"Sitting in the TARDIS, making out like La La La!"
The Doctor was laughing so hard he forgot to notice that his fez was stolen by a cheeky Alicorn.
"WHEEEEEEEEEEEEEEEEEEEEEEEE!"
Discord was already blindly making his way through the TARDIS.
Rainbow Dash opened her eyes to see her sucking muzzle with Fluttershy.
In a surge of surprise, they pushed apart.
"What was with the tongue thing?" Rainbow Dash asked in fury and confusion.
"I don't know, but you were playing along!" Fluttershy said with an surprisingly loud voice.
"Eh, it was great when it lasted." the Doctor said while tripping Discord and snagging his fez back. "I declare this a shipping fail."
"I wanted Dashmeister as my brother!" Discord shouted. The former draconequus sat on his butt and dragged it while casting a magic spell which made his butt into an inky felt tip. He proceeded to scribble on the TARDIS' floor.
The TARDIS hummed its ever-so-familiar hum.
The time machine spun to another path, taking the destination elsewhere.
"Discord. You stay behind." said the Gallifreyan. He then turned to the two pegasi. "You lot, come with me."
Fluttershy and Rainbow Dash proceeded with the Doctor outside.
Discord, being a disobedient little tart, trotted silently with the fully-growns.
Year 1 AH(After Humanity)
The three hitchhikers were greeted with a beautiful sight: The world rampant with beauty, lush life and a new, fresh feeling.
"Believe it or not, this is the year after the humans became extinct." The Doctor said.
A being resembling an Alicorn, but with more cosmic prowess and a more powerful aura, along with a strikingly familiar draconequus, were flying about, sending earthquakes out and about.
"Oh no!" Fluttershy squeaked.
"Is that Discord?" Rainbow Dash furiously shouted. "When I get my hooves on--"
"Calm down!" said the Doctor, with a voice that seemed loud only to the speedster. "They're actually separating the lands and assigning creatures of a race to their ideal spot as we speak." He smiled when he saw the primitive ponies. "We're in Equestria. To be exact, this is where the tiny town of Canter will be placed."
"Don't you mean Canterlot?" asked Rainbow Dash.
"No...actually, not yet." the Doctor said. "Celestia wouldn't be moving into Canterlot until--whoops, spoilers."
"Who are these?" said the first being to the second. "It's as if they know our purpose."
The beings proceeded to descend in front of the Doctor, Fluttershy, Rainbow Dash, and unknown to the three, Discord.
"Gallifreyan." spoke the first being. "You dare mess up the timeline?"
"Nope, we're just here for a stroll." the Doctor said cheekily.
"His presence determines the otherwise to be true." said the second being as he pointed to Discord.
"Who--I told you to stay INSIDE!"
"Why?" asked the former draconequus.
"Because you, I, we, are in the past." the god replied.
"I-I-I-uh-I...w-w-was...y-you?" Discord stuttered.
"I feel your spiritual link with me." said the first god to the speedster. "And the other pony, no...of all gods..." He broke into sorrow.
"We'll be off." the Doctor said. He hoofed out two vials. "Drink these when we leave."
The Doctor pushed the three others into the TARDIS and set coordinates.
The two gods watched as the time machine fades into nonexistence.
Of course that was in their perspective.
"Maverick?" asked the young Discord.
"He said to drink when they left."
"Okay it is."
The two gods drank the contents of their vials.
"Why are we standing here?" asked Discord.
"When we have a planet to organize?" asked Maverick.
They flew to the sky, proceeding with their usual duties.
Inside the TARDIS
"Wrong year! Wrong year! How did I miss that?" the Doctor ranted as he re-calibrated the coordinates.
"Discord saw himself?" Rainbow Dash asked.
"We messed up the timeline?" Fluttershy added.
"Only when those gods noticed us. Wanna know a fun fact?" the Doctor asked.
"Uhh..." Discord answered for all three of them.
"The other five gods of creation gave their own lives to create the universe." the Doctor said with a grim tone. "Now we're headed to Maverick's castle, during the time when Princess Celestia and Princess Luna are settling in."
"Anyone of importance?" Discord asked.
"Nah. Not--WHAT ARE YOU DOING?" The Doctor raised his voice at Discord who was fiddling with the TARDIS' controls.
The Doctor, frantic, tried to re-calibrate the time machine, but he couldn't.
"Oh great. We're stuck outside space-time." He sighed and kissed the fabrication panel of the control console. "Rest for a while." he said to the TARDIS while patting the time rotor.
The Gallifreyan told the Alicorn about the library which had a swimming pool. The Alicorn ran to the TARDIS' halls, using a honing spell to bring him to the place instead of having to listen to the Doctor's instructions.
Rainbow Dash was just staring dizzily at the control console. What she didn't know was Fluttershy nibbling at her ear.
The timid pegasus continued her tiny licks and nibbles on her longtime friend's cheek and neck.
Until the Doctor nudged them.
"There ARE rooms in the TARDIS...I don't want to tell Clara that two pegasi mares consummated here." The Doctor said. "Go, you nutters." 'Thankfully ponies are not hermaphroditic. If otherwise, another River Song is on my problem list.'
The pegasi went to the rooms. After a few seconds, Discord arrived.
"I swam like a dead fish."
"You mean you floated?"
"Well, sorta."
The TARDIS danced around space-time for a few hours. The Doctor assisted her in repair. Pretty soon, the TARDIS returned to exactly when they left.
The Doctor opened the door. He peeked out and saw the night sky, with Princess Luna waiting with a stern glare at the alien.
"The TARDIS sure likes to play." he said sarcastically.
Discord approached the older Alicorn with his head down. "It was my fault. I sneaked inside the TARDIS."
"No. It was my fault. I flew to the entrance to get Discord out." Fluttershy added.
"No. Rainbow Dash, charging foul. Bench me, Princess." Rainbow Dash said, raising her hoof.
"Nah, you fools are making yourselves look like, well, fools." The Doctor said, bringing out a wooden sign. "No Parking for TARDISes."
"It's not that. Discord, you will have your exam tomorrow." Princess Luna said. "Twilight Sparkle will tutor you. Take all the time you want, provided you start and finish the exam, tomorrow. Approach my sister when you are ready." She flew off.
Discord, the Doctor, Fluttershy and Rainbow Dash stared, mouth agape, accompanied by the TARDIS mimicking the sound 'Wa wa waaa...'
