AN: 2/2

Doctor: 12th

They have often spoken of how the Doctor regenerates, but they have never seen it first hand. Until now.

Golden light explodes, expands, engulfs, almost as if it's burning him away.

John shields his eyes, seeing Sherlock has done no such thing. He wouldn't miss this.

It stops as suddenly as it started. A different man stands where their friend had stood, yet they know that he must be the same. Just… new.

The first thing the Doctor does is rip out a few hairs from his head and examines them.

"YES!" he shouts in his new voice, "FINALLY! GINGER!"

AN: And that's all she wrote. Thanks for reading and commenting, and enjoy the Christmas special in a few days :)
