"I don't want to go!" the Doctor exclaimed, clutching the railing of the Tardis.
The yellow mist drifting around his fingers showed the fact he was about to regenerate. He cried tears of pain as everything he was and had been in this form was about to end. He suddenly screamed as his hands, feet and head erupted into explosive beams of yellow-orange light. The windows of the time machine smashed and shattered. The pillars supporting the main structure collapsed. The control panels burst into flame.
"Aaargh!"
The newly regenerated Time Lord staggered around the Tardis trying to regain his balance.
"Legs? Legs! Yes! I have legs! Eyes. Nose. I've had better! Ears. Hair. I'm a girl! No…no! I'm not a girl! There's…there's something else…something important…I'm…I'm…I'm…I'm crashing! Woohoo! Geromino!"

The blue box plummeted towards the Earth below.

"Oh this is bad…very bad…very very bad!"
The alarms bleeped crazily as the Time Vortex opened and swallowed the Tardis and the Doctor.
