Decided to tease you all again with a short chapter. I have a feeling this story's gonna be really short (or at least, you know, six chapters minimum) and I figured out a major plot twist! But I won't tell you til later. So, please tell me what you think. And I don't mind corrections where corrections are needed :)

Disclaimer: I do not own Doctor Who or Sherlock.

Chapter Four:

Doctor John watched as Amy and Rory disappeared around the corner, hand pressed to his cheek. Behind him, Jack coughed awkwardly and Mycroft tapped his umbrella against the ground. Sherlock stepped forward, peering at the Time Lord with as much concern as an Anthromechanocyte could possibly muster. "Are you alright?" He whispered.

"Yeah. I'm… used to it." Doctor John muttered, turning away from where the Ponds had disappeared. "Anyway… you were taking me to my TARDIS."

"You don't want to go after them, Doc?" Jack queried with a frown.

"I just told them that their only daughter is dead. I doubt they want to see me right now."

"Okay, Doc. This way." Jack gestured to a door, which slid open at his touch. "So, Doctor, where've you been all this time? And why'd you leave the TARDIS just lying around?"

"I didn't just leave her lying around! I had her parked quite specifically. You moved her." Doctor John replied.

"I did it for her safety." Jack retorted, opening another door and standing back. "She's in there, Doc. Go say hello."

John rushed through the door, heart banging against his chest. He couldn't help it if he was grinning like a five-year-old who had rediscovered their favourite toy, and he certainly couldn't help the spring in his step as he skipped towards his beloved blue box. "Hello, old girl! Did you miss me? I sure as hell missed you. Well, I've missed you for as long as I've been a Time Lord again. But never mind, because we're together again!" He declared, throwing his arms around what parts of her he could reach. Later, he would swear he felt a joyful hum in response to his touch.

"So… this is your spaceship?" Sherlock queried, stepping into the room and running his eyes over the TARDIS in a way that was almost indecent.

"She's my TARDIS. And I'm her Time Lord." Doctor John answered.

Sherlock raised an eyebrow. "Her Time Lord?"

"Yes. She stole me, and I her."

"You never told me that story before." Jack muttered, sidling up to John's other side.

"That's because I only ever heard her side of the story after you had gone. Or, I had gone. The other me, I mean." Doctor John jumped back with sudden vigour, clapping his hands together. "But enough of that. Let's get inside, people to do, things to see!" He exclaimed excitedly, then paused as his brain caught up with his mouth. "Wait, stop, reverse that. Things to do, people to see."

Jack snickered in a manner that was most certainly not fitting for an adult.

"Captain, please try to maintain a shred of maturity." Mycroft said with disdain, rolling his eyes. "You still, however much you may dislike it, work for the government and we must preserve a certain image of authority and dignity."

Jack grinned. "As you say, Sir."

"Jack, stop it." Doctor John told him sternly, opening the door of the TARDIS and stepping inside.

"Stop what?" Jack asked innocently.

"Stop flirting."

Jack huffed and strode in after the Doctor. "I wasn't flirting. I would never flirt with a superior. It would be inappropriate." He added, looking scandalized.

Doctor John laughed. "Right, sorry. I must have been mistaking you for someone else." Glancing to the door, he noted that Sherlock and Mycroft were still hovering outside. "You can come in, you know."

"We're waiting for permission." Mycroft said.

"I just gave it."

"Not from you." Sherlock said, looking up.

The TARDIS hummed and shuddered, the console glowing pleasantly. A few of the loose wires sparked. Mycroft and Sherlock stepped inside, ducking their head to the console. Both Jack and Doctor John frowned.

"Er… are you two bowing to my TARDIS?"

"We were raised to have manners when in the presence of a superior being." Mycroft replied.

"All right then." Doctor John turned back to the console and started to pull up various readouts and images on his monitors. "Hmm, we'll have to take it to Cardiff so it can absorb a few more Huon particles." He said absently.

"What about this… Silence?" Sherlock asked.

"That's in the future. All I have to do is key in the coordinates and we'll be there after I left."

"What about Amy and Rory?" Jack queried.

Doctor John was quiet for a moment, pretending to straighten something. "I doubt they'd want to come with me… be near me. After all, I'm the reason their daughter is dead." He said in a whisper.

"Doctor, you must really be dense if you think we'd wait all this time to just let you get away from us." Amy declared, walking into the TARDIS, husband in tow. "Granted, when this is all over I'm going to beat your backside black-and-blue, but my daughter was willing to, and did, die for you, so you must be bloody well worth it."

"Amy." John said, a slow smiling spreading across his face. "Rory."

"I'd like to point out that I'm still mad at you… but you're also my friend. And I know that everything you do, is to help people. That's- That's what I want to do. So… I- We- We're willing to- to push away our grief, to put it in a little box until this all over, and do what needs to be done." Rory said quietly.

"Right, then. Let's get going." John replied, grabbing a lever and pulling it down sharply. As the TARDIS rumbled and groaned, jolting its passengers, Doctor John couldn't help but grin, because his two worlds were not just colliding, they were melding together.
