Sherlock blinked twice. Police box, why did that feel so significant to him. He stood up and quickly walked out into the kitchen, John followed behind slowly. Sure enough, there was a large, blue police box sitting in the kitchen.
"How did that get here?!" Sherlock yelled in frustration, he couldn't think properly, his head hurt. Then he remembered. "Doctor?!" he yelled "River?!"
"Sherlock what are you on about?" John asked. Sherlock ignored his friend.
"Doctor, are you in there?!" he asked, banging on the front door of the box.
The door creaked open slightly, a man with a bow tie and tweed jacket stepped out, "hello, Sherlock." He smiled and pulled the detective into a tight hug.
John was confused, "what's going on?" he asked "did I miss something?"
"Ah, hello! You must be John Watson." The Doctor smiled and shook John's hand. "I'm the Doctor."
"Doctor who?!" John asked, Sherlock smirked.
"This is the Doctor, that's his name." Sherlock explained, "he's my father."
"I've met your parents." John said "they don't look like that." He pointed at the Doctor.
Sherlock sighed, seeing the police box had made new memories awaken in his mind, he could explain everything now. "The Doctor is a time traveller, and alien time traveller. His species is the Time Lords, he and his wife – my mother – knew it would be too dangerous for me to live with them when I was younger. They dropped me off with a nice Human family in England and I grew up thinking they were my family." He stated, bluntly.
"What?" John said.
"It's true." The Doctor smiled, "I can prove it." He opened the police box door wide enough that John could peer inside.
"It's called the TARDIS." The Doctor and Sherlock said in unison.
"Time And Relative Dimensions In Space." Sherlock called, smirking.
"It's bigger on the inside!" John said, "how does it do that?!"
"Dimensionally transcendental." The Doctor said.
"Basically another dimension." Sherlock said.
The Doctor rolled his eyes, "you are totally your father's son."
"I know." Sherlock replied.
"So, want to travel with me?" The Doctor offered
"Oh, Dad." Sherlock said "I was born to."
