Chapter Five: The Explanation

"Doctor? What the HELL are you doing here?" Jack said. "The last time I saw you was in a bar in the 51st century." He walked closer to the man. "And if I remember correctly, you looked different."

The Doctor looked around the Captain at Sherlock and John, who were rooted to their spots; shocked. He glanced up at Jack and said: "Well, my time for my old body ended. It was time for this new one." He plunked a Stetson on his head. "My thing now are these clever little hats and this bowtie." He tugged at the ends. "Bowties are cool."

Jack raised his eyebrows. "Uh-huh. You just keep on believing that." He turned his attention to one of the women behind the Doctor. "Captain Jack Harkness," he said, taking her hand and kissing it. "And who are you?"

The woman smiled and said: "Amy. Amy Pond."

"Oi! Watch it, Mr. Smooth. That's MY WIFE you're kissing there." The man said, stepping closer to Amy and taking her free hand in his. "And I'd really appreciate it if you would stop, please."

"Oh, where did you pick him up Doctor?" he yelled sarcastically. "He seems like a REAL catch."

Amy turned and looked at her husband.

"I don't mind, Rory. Really."

"Yes, I know you don't Amy. But I do."

The Doctor spoke up. "You three. If your bickering is done now, I would like to explain to Jack WHY my TARDIS landed here, alright?" The Doctor walked towards Jack, clapped a hand on his shoulder, and steered him in the direction of Jack's base. "Walk with me." As they walked past the two men still rooted to their spots; the taller of the two spoke.

"How…? Why….?"

"Ah, Sherlock. Glad to see you back with us." He turned and poked John in the shoulder. "Are you there? Wakey wakey!"

John shook his head; bewildered. "Bloody Hell, Doctor. Don't do that to us."

"Sorry." The Doctor said. "I really can't help it sometimes. The TARDIS has a mind of her own. She goes wherever I am needed." His face lit up; suddenly remembering something. "Which reminds me…" He pulled out his psychic paper out of his coat pocket. "Did you write this message?" Both men shook their heads.

"No, Doctor."

The Doctor walked away from them then; talking to himself. "Interesting. If neither of them wrote the message, then who…?" He whirled around. "Jack?"

"What? Oh no. I don't have time. I am running Torchwood now, remember?"

The Doctor waved the question off. "Yes, yes, I know." He started pacing. "Who could have written me the message?" Just as he was making his fifth turn; the TARDIS door opened.

"Doctor! I have a lock on who wrote the message." The female voice said.

"Hmm? Ah, excellent! Oh, River you're brilliant!" He rushed to the police box, followed by Sherlock, John, Amy, Rory and Jack.

"I know," River said. "What would you do without me?" She turned the screen toward the Doctor. "Apparently it's coming from underground. There's some sort of tunnel system underneath the whole city of Cardiff." She started typing on the keyboard. "And according to reports…they've been there since the city was founded."
