De-aged
A/n: hello this is my 2nd fan fiction so be ready for mistakes and spell mistakes, well, it as an alternate universe where Lucy didn't shoot the master he and the doctor sort of traveled together, he doesn't have a choice, when coming across some aliens who use a de-aging potion on the two of them they start to DE age but not into their past regeneration no just look younger, read the story for more. Also jack is with them.
The master slumped along behind the doctor and in front of Jack; he had asked to stay in the Tardis but the doctor refused.
"Allonsy" smiled the doctor.
Jack smiled back at the doctor and slowly came to halt.
"Doctor, why! Run!"
Sudden blast hit all three of them but they all managed to stay on their feet the doctor did what he did best which was run, funnily enough the master was great at that too, they come to halt in front of the Tardis as the doctor opened the door they all started to shrink and look younger, the doctor opened a cupboard door and pulled out three vile.
"Drink this!" he shouted over the Tardis engines and passed them round.
The doctor and the master poured it down their throats in one, jack however sipped at it, it was vile.
"What was it?" jack questioned.
"It will stop the de-aging, soon" doctor returned with a grin on his face.
"When will it stopped?" the master said out loud, as though speaking to the doctor and yet himself all at the same time.
"Now" said the doctor.
Just as they all stopped they were all so small and yet still intelligent, the doctor and master walked over to the bookcase and started to rip the books from their shelves.
"It's here somewhere" the doctor murmured.
"Found it" shouted the master.
Passing the book over to the doctor he said calmly we have landed, all three looked at the Tardis doors.
"yes" said the doctor "the Tardis has created us all fake names except you jack you'll have your usual name, drink this jack it will help you as to them now you're a muggles we are more or less magic, now we should probably wait a couple of minutes."
