Destroyed Daleks burned in the streets of Christmas. Clara, the Professor, Mr Gold, Belle and the townsfolk came out of the church. The Professor looked up at the destroyed church tower. But there was no sign of the Doctor.

"We'll find him," Clara whispered to him, feeling how he felt.

They spotted the TARDIS, and they approached the blue box. Clara hung up the phone receiver dangling from the outside cupboard. Then, they entered the TARDIS, and they looked around nervously. They didn't know what they would find. Or who they would find. There were clothes strewn on the floor. And a bowl of fish fingers and custard on the console.

"He always did love his fish fingers and custard," the Professor said.

Hearing footsteps approach them from behind, they turned around and saw the Doctor coming up the stairs. He was young and fresh.

"Dad!" the Professor smiled. "Hello," greeted the Doctor.

"You're young again," Mr Gold stated.

"You didn't even change your face," Clara said.

"Ha! It's started. I can't stop it now," the Doctor said. "This is just the reset. Whole new regeneration cycle, oh!" He took the bowl from the console and guzzled the custard. "Taking a bit longer. Just breaking it in." He hobbled around the console and pulled a lever. "Oh!" he grunted as lights came on and counter-rotating mechanisms spun overhead. "It all just disappears, doesn't it? Everything you are, done in a moment, like breath on a mirror. Any moment now, he's a-coming."

"Who's coming?" Belle asked. "The Doctor."

Belle tilted her head in puzzlement. "But you are the Doctor."

"Yep, and I always will be," the Doctor strained. His hand started to glow. "But times change, and so must I." The Doctor turned his head as he saw a young redhead girl run up the steps to the balcony of the console room. "Amelia?"

Clara looked around. Who else was there? "Who's Amelia?" "Amy Pond," the Professor answered.

"And she's here?" Mr Gold asked.

"She was the first face this face saw," the Doctor explained as he watched the young girl that only he could see run past the walls that were covered with children's pictures. "You know, we all change when you think about it. We are all different people throughout our lives. And that's okay, that's good, you've got to keep moving, so long as you remember all the people you used to be. I will not forget one line of this. Not one day. I swear. I will always remember when the Doctor was me."

A young woman with black painted fingernails, long red hair and a leather jacket descended the stairs. She walked up to the Doctor and smiled. "Raggedy man." They caressed each other's cheeks. "Goodnight."

There was no one else there to the others—just the Doctor. He looked back at the others before taking off his spotty bowtie and dropping it. The Professor closed his eyes, hanging his head low, and held Clara tightly.

The Doctor glowed, smiled and was rocked backwards by the force of the quick, sudden change. He became an older man with grey hair and piercing blue eyes. Above his eyes were a pair of thick eyebrows. He studied the others in the room fiercely. He suddenly collapsed and clutched at his midriff as he got close to them. He groaned in pain. "Kidneys!" he exclaimed in a Scottish accent. "I've got new kidneys. I don't like the colour."

Mr Gold looked over at the Doctor and approached cautiously. "Of your kidneys, dearie?"

The TARDIS shook, and everyone lost their balance. The Doctor went to the console, followed by the Professor.

"What's happening?" Clara asked, holding Ellie tightly. "We're probably crashing!" the Doctor answered.

"Into what?" Belle asked.

"Just stay calm," the Doctor said. "Just one question … Do you happen to know how to fly this thing?" He then looked beside him and saw the Professor at the console. "That's awfully lucky, isn't it?"
