"The winds of change are blowing doctor...for you and me both" said the first doctor. His old face contracted in wrinkles of thought.

"I know, but you can't expect me to just keep on changing."

That is the curse of the Time Lords Doctor… nature will always get what she wants.

"See you later Doctor"

"I look forward to being you, Doctor. Until then I suppose I'll have to forget everything about you and our wondrous and outrages and frankly ridiculous sounding future. I'll go now. We both need to go through some changes.

"Oh! Wait a minute!"

"Is there a problem?"

"No not a problem, no, just a little something I have to do for every one of us but more particularly for number 8.5, ten and eleven. just can I have your sonic screwdriver for a second?"

What? This old thing? And can I just say that I have absolutely no idea of what you are mumbling on about."
The first doctor took out a pen like device and held it up into view."

"Yes, that old thing! You'll understand… also! don't underestimate the power of the sonic! I just gotta do something with it... I'd tell you but... you know ... spoilers and all that.
Hold on to that. It's gonna save your life about a million times."

"You say the most ridiculous things... but if you say so." He let the sonic screwdriver glide in his pocket.

With one last smile the first doctor turned around and disappeared in the snow.

"Alone again..." the remaining doctor thought

"And you old girl! You just had to prove a point didn't you?!" he smirked.
Taking me to see Me only minutes before my first time regenerating... what are you gonna do next? Bring me to the Powell estate?"
He laughed to himself.

"Oh well I don't have a choice do I?
The universe needs me... I can't exactly stop being the doctor in a universe at war, now can I?"

"No matter what I will always be the doctor!"
He was screaming in silence at the skies above, letting them know he might change his shell, bit within he'd always be the hero everybody needed. The bringer of hope!

He turned on his heel, snapped his fingers and stepped inside the Tardis.

You know. He sighed. I never say anything to you… but let just say I'd be nothing without you, old girl.

A soft, warm whirlwind hit his legs. He knew she understood his troubled mind.

Her interior pulsed with light, basically telling him that she understood but that he could no longer hold back his regeneration or else he would die.

"Oh well here goes number thirteen.
For ones please be ginger."

The room bathed in golden light and the doctor screamed in pain.

Seconds later the light died down and in the same place the twelfth Doctor ones stood now stood lucky number thirteen...
A blonde woman.
"Wha- what is this? This feels... different. What?! Oh my!"
