"I honestly can not believe it," Hermione Jean Granger proclaimed in front of all of the Death Eaters and Order of the Phoenix. It was at the final battle, and Hermione's secret was about to be discovered. "I had at least expected you, Harry, or you, Ron, to have figured it out sooner but apparently not. I mean seriously, I have a bag that's bigger on the inside and I time travel. Give any hints?" Hermione said to all of the shocked people. Then, Voldermort started to realize it.
"I mean, I understood that joke that came from Mr. Barty Crouch Jr. and yet you didn't stop and think why I knew? Bloody hell," She swore. "I had at least expected Voldemort to figure it out, I mean, well, never mind," She said stopping herself.
"Oh my non existant nose," Voldermort said, "You're, you're a timelord! And to think after all this time, all of my dreams of finding the TARDIS and a time lord, being his or her companion, that I would find out my enemy is a timelord!"
"Can someone bloody tell us what a time lord is?" Harry and Ron screamed.
"I think I can help with that," A man that looked very similar to Barty Crouch Jr. stepped out of the TARDIS. "I'm the Doctor and I'm a time lord. So is your 'Hermione Granger' who is by the way The Mechanic is," The Doctor said as he explained time lords to the wizards and witches. The poison in Hermione, or should I say, The Mechanic's blood system raced towards her heart. She began to regenerate.
Everyone stopped and stared at her, pointing fingers and such. When the process was done, she had black hair in a ponytail, black eyeliner, and a black leather jump suit with a black leather jacket on top. She had her timelord pocket watch hung around her neck as a necklace. She looked to be about the age of the Doctor.
"Now then," she said, "Doctor, I think it's about time we take our leave."
They left towards the TARDIS when they were stopped by running and yelling.
"Wait!" Voldermort yelled as he ran to them, "Take me with you!"
The Doctor and The Mechanic looked at each other and said in unison, "Why not?"
So thus that is the story of how the Doctor, the Mechanic, and Voldermort traveled around the galaxy, through time and space, to become famous for their good deads.
