Just then John walked in the door, preoccupied by a mobile phone. "Sherlock, you'll want to see this! Lestrade believes he's already solved the-" he stopped abruptly, noticing the stranger in the room. "Oh, hello. Who's this? Where's Molly?"

"He calls himself-" Sherlock began.

"Hello, I'm the Doctor!" The Doctor interrupted. "John Watson, I remember you! Guess I never realized how popular this day is for me. If memory serves me correct, you'll find me back at Baker Street. Course I've regenerated since then so just know it really is me. It's been a pleasure to see you again, old friend!"

"Did you tell-?" John glared over at Sherlock.

"Nope. I have no idea who this man thinks he is. He says he's the Doctor. Judging from his looks he could be in his late 30's but he speaks as though he's much older. The pulse in what might be his jugular vein is twice as fast as any normal man at best and erratic at other times. Perhaps a heart condition but you're the medical doctor, John. The worn clothing suggests that he travels often and finds himself in dangerous situations. The bulge in his suit jacket could be a weapon but it has no distinct shape of any gun. His intentions would appear to be to take me with him on a journey, whether willingly or by force. His accent is British but not quite like any regional area in the UK. He claims to have met Molly a while ago but as long as I've known her she's never spoken of him. He's either a dangerous liar or quite an interesting client."
"Fantastic! I love when you do that!' the Doctor beamed at Sherlock, "although you're a bit wrong in that I'd never force you to come with me. And my hearts are beating just fine, thanks"

"Hearts? As in multiple? That's impossible- How did you know my name if he didn't tell you? Who are you?" John looked so dazed and confused. He stared as the man who called himself 'Doctor' remained silent. John looked over at Sherlock who was intently studying the strange man. Suddenly, Sherlock gave a quick smirk with a gleam in his eye that could only mean he had figured something out.

"I get it now. Even Anderson's craziest theories were based in fact. You are indeed the Doctor, as portrayed by the BBC on Doctor Who."

"So he's an actor?" John piped up.

"No, he's an alien. You watch more telly than me, John. Honestly, just think about it." Sherlock continued to smirk at the stranger who began to grin.

"That's it. You've gone mad," John began to chuckle. "Well, it was nice meeting you, Doctor- whoever you are. I'm going to go break the news to the landlady that the world's only consulting detective has lost his mind." With that John turned to leave, muttering curses about pranks and science fiction nonsense. He walked out the door of the lab and took the lift down to the ground floor. He was still muttering when he pulled knocked on 221B Baker Street. Inside he heard the voice of Mrs. Hudson and a strange male laugh. Seething he slammed the door shut and stormed towards the kitchen. "Ok, this joke has gone far enough, whoever the hell you bloody lot think you are! If you don't leave right now, I'm calling the police-" he stopped short as he looked at a man with close cropped hair, a leather jacket, and a plain jumper. The man gave him a comical grin made even more ridiculous by his larger-than-life sized ears and nose. The man stood and held out his hand.

"Oh, John, this is the Doctor! He's an old friend of mine," Mrs. Hudson exclaimed from her seat. John just stared at the proffered hand. The Doctor grinned at John.

"Hello!" the Doctor exclaimed. "Fantastic meeting you, John. Want to see the stars?"

-Author's note: I've finally started watching more Doctor Who so this story will probably be updated a bit more regularly now. I'm so sorry to have kept you waiting so long and I really appreciate your enthusiasm; it keeps me writing. Thank you all!
