Given my need to make this story a current as possible, I've added in the Doctor from the ending of "The Name of The Doctor" (aka John Hurt). Since there is no explanation or really given personality of this new Doctor, I've just played him out as I would see him
Chapter 2
Somewhere in the middle of the galaxy
"Turn the breaks off. This screeching is killing my ears!" the old man complained as they left Trinzalore.
"What? No, we are not turning off the breaks! First River, now you?" the younger man screamed at his older looking self
"You two stop it now!" Clara yelled from the upper railing of the TARDIS console room. Ever since the Doctor and the Doctor escaped their timestream, they have argued non-stop about every little thing. The arguments ranged from the way the Doctor did his hair all the way to how he should get rid of the bow tie because it looked stupid, which was a really heated battle.
"You need to get rid of that ridiculous scarf and this fez. The scarf was comfortable and absolutely flashing in the day and now I'm just wondering 'What was I thinking?' and as for this red excuse for a hat-" The old Doctor complained before being cut off
"Now I remember why you were my secret, cause you're so annoying! You know what, that's it, we're going back to Trinzalore and getting rid of you." the Doctor told his older self. He then went to the console and began pressing buttons. The TARDIS made a high-pitched screech (not the parking/ take off screech) which basically meant 'I'm sorry but we are not going back there. I'm also still drained from you forcing me there in the first place Doctor' in TARDIS warning screech.'
"Why now girl?" he asked the TARDIS as he hung his head in defeat.
"Because she likes me more." the older Doctor claimed
"You take that back!" the Doctor snapped. "Tell me it's not true girl" the Doctor said to the TARDIS
"You have to be kidding me right now." Clara said to herself in disbelief at how childish the two Doctors were. "They are acting like toddlers fighting over a toy" she thought. She was done with these two for now until they could stop arguing. "That's it, that's it" she said to herself. The Doctors we're still arguing except this time it was about the interior design of the TARDIS console room.
"I liked the one you had when you had spiked hair and wore those stupid sneakers. This design is too gloomy and dark." the older Doctor complained.
"Oh I'm sorry, would you like me to degenerate? So you can get your spiked hair back?" The Doctor asked in an offended tone
"No, that one was too smart-looking and childish."
"What? That's not true."
"He explained time as timey-wimey"
"Wait, isn't he, the older you, the same as all of you?" she asked the Doctor
"Yes of course, he just likes to refer to me and my previous selves a he or him and not I or me." he explained
"That's a bit rude." she told the older Doctor
The older Doctor was about to respond when a bell rang throughput the TARDIS. "You have a clock in here or something, Doctor?" Clara asked. The two Doctors looked at each other with worried looks. The Doctor moved and looked at the console screen and began to mumble things under his breath mostly just possible things that could set the bell off. The older Doctor looked confused then his face turned ghostly white and Clara noticed.
"Doctor, what's wrong?" she asked the older one
"This never happened" he said silently. He ran to the Doctor who was still trying to find what's wrong, grasped his shoulders, pulled him into his stare, and said "This never happened Doctor." he said clearly and louder. The Doctor knew then and there what was happening.
"Go, you know where to go." The Doctor said to his older self. The old man ran through the door that led into the depths of the TARDIS and disappeared after running down the hallway to the right.
"Clara get ready!" the Doctor screamed
"What's going on?" she asked. The Doctor went to the console and hit a big red button, which made the TARDIS console room shake and the console burst with sparks.
"Clara, I-" the Doctor tried saying
"AHHHH!" the old Doctor screamed from within the depths of the TARDIS.
"Oh no." the Doctor said as an explosion of bright light. When the light cleared, the Doctor and Clara were in the TARDIS just as before.
"Doctor, nothing happened." Clara said
"Let's find out." the Doctor said. He walked up to the door to exit the TARDIS when the Doctor extended his hand to Clara. She took it and together walked out of the TARDIS and into a graveyard in the middle of the day. The graveyard was next to a church and was spotted with trees. The TARDIS was parked inside of a tree, which was new, and luckily only the blue doors were the only visible part of the TARDIS.
"Well..?" Clara questioned "What now?"
"Simple" the Doctor said
"You turn around or I shoot." a gravely voice demanded from behind demanded. Clara and the Doctor turned around to see a man with thick and curly black hair and a pale face. The mysterious man wore a black overcoat with the collar turned up and a blue scarf around his neck.
"What do you want?" Clara asked
"Nothing really, I just want to know how you found me" the man answered. "You judging by how well you all are taking this and how you all showed up just as my friend was leaving I'd suggest you all work for Moriarty."
"Moriarty?" the Doctor thought. "No..." he said slowly as if he were about to fangirl out. "You're...you're..." he said excitedly. The man suspicions changed, the man next to the girl in front of him dressed like a professional, his clothes were well worn meaning he'd worn that suit a lot, his hands seem well worn too, his facial features said he was older than he looks and smiles quite often, the bags under his eyes showed that he didn't sleep much which may also mean he has seen a lot of things, some maybe unspeakable. This man at his gunpoint was a doctor of some kind although more likely to be a battlefield doctor like John, but this man seemed to have been in more action in a war than John.
"He's what?" Clara asked the overly excited Doctor
The man lowered his gun "I am Sherlock Holmes"
