There was a bright flash of light and suddenly the previously empty room was filled with a multitude of different people. There was 14 of them in total and they where all lying unconscious on the ground but 5 of them quickly woke up. After they all looked around at everyone else in the room confused the 12th doctor groaned "great" and the 9th doctor said "Who are you?" Meanwhile the 11th doctor excitedly jumped to his feet and said "Oh this is brilliant. Absolutely fantastic" he made his way over to the 10th doctor who had also got to his feet and said "now that is proper skinny" before turning his attention to 9 and saying "oh and those ears." 9 just responded with "Oi, what's wrong with my ears!" 11 just laughed at this as realisation dawned on 10 as he said "wait, if you're here" he said pointing to 9 before turning to 11 and saying "then dose that mean that you're" but 11 just winked before he could finish and said "I think he's got it." 12 then stepped forwards and said "can you stop acting like a two year old just for five minutes ." But before 11 could respond 9 said loudly "I'm sorry, but can someone please tell me what's going on, who are you?" 10 and 11 both then held up their sonic screwdrivers in sync and realisation dawned on 9 as he said "you're me" and at the nods of the other two he said "great"
10 then turned to 12 and asked "but who are you then?" But before 12 could respond missy stepped forward and said "well isn't it obvious, he's you as a grumpy old man." 11 suddenly looked confused and cautious as he said "but that shouldn't be possible?" And 12 just shrugged and said "just accept it, makes life a lot easier." After that 10 turned to Missy and asked "but then who are you?" To which Missy just responded with "I'm Missy" and 9 when asked "who?" She just shrugged, smirked and casually said "well I couldn't keep calling myself the master now could I" 9, 10 and 11 where both stunned silent by this but 12 just said "but you will not be killing, mutilating or in any other way harming anyone in this room, will you." Missy just pouted at this while winning "but that's so boring!" But before 12 could respond to this 10 spluttered "but how are you still alive?" Missy just raised an eyebrow and said "I'm honestly amazed how you are always surprised that I'm still alive, I would of thought you'd be used to it now." They all thought about the amount of times the master had managed to surprise them like that and the admitted that she might have a point.
After that 9 clapped his hands together and said "alright, now that introductions are out of the way, what the hell is going on here?" All 5 of them looked around the room which was dark, like a cinema, and had 4 sofas and a massive flat screen tv. 10 then said "I'd say that we're here to watch something" and 11 said "good, I like watching interesting things. Not boring things though, those are boring." And 9 just said "How is it possible that I can become more childish as I get older" and 12 said "we grow out of it eventually" and 10 and 11 just said "oi" in unison.
Just then everyone else started waking up and started asking questions immediately. Amy asked "doctor, what's going on?" And 11 responded with "well we were all brought here, don't know who by, but we think we're here to watch something." Jack then got to his feet as he asked "but who are you all?" And 12 said while gesturing to all his regenerations "well we're all the doctor" Most people looked confused at this and Rose asked "what do you mean you're all the doctor?" 10 who had been staring at Rose sadly, said in his usual cheery tone "regeneration" but when nearly everyone gave him a blank stare he elaborated with "basically whenever a time lord comes close to death we have the ability to change everything about us. Appearance, personality, everything. Anyone understand?" Amy still looked confused along with many others but just responded with "not at all but continue." 11 then rubbed his hands together and said "right then, introductions. I'm the 11th regeneration of the doctor so call me 11." After that they all went round and everyone introduced them selves and all the humans said which doctor they traveled with although Missy didn't say she was the master.
After this Missy said "right let's get going, some of us have things we want to do, planets we want to conquer." 12 then turned to Missy and said "after this you're going straight back to the vault. Not conquering any planets." Missy simply rolled her eyes and muttered "spoil sport" Nardole looked at 12 nervously before saying "Sir, please tell me she's not planning something evil." But instead of reassuring him 12 just said "probably, but she won't be doing anything" Missy just rolled her eyes at this as Rory asked "I'm sorry, are we safe around her?" 12 said "yes" at the same exact time as Missy said "no" leading to a slightly awkward pause which 11 broke by saying "should we start then" and there was agreement throughout the whole room even though Rory still stared at Missy suspiciously and held Amy close to him. Once they where all settled the TV turned on and the words 'the empty child' flashed across the screen.
I just thought I should put when all the characters are from:

Martha- after blink
10 and Donna- after midnight
11, Amy and Rory- after night terrors
Clara- after under the lake
12, Bill, Nardole, Missy- after empresses of mars
