I'm not sure how many chapters I want to do... I'm having too much fun writing this.

I could always just do spin offs!

Lotsa interludes in this one...

The Doctor was still sitting with Rose in the waiting area when Sherlock and John came into view, followed shortly thereafter by the three Ponds.

"He still in surgery?" Rory asked.

"Yeah, should be another hour or so..." Rose answered, and they all stood quietly. The Doctor fidgeted with his hands and Rose smirked, "Look, Doctor... My mum's on her way, and while I'm sure she'd love to see you..."

"Oh, right... We should get going anyway." The Doctor said, his brow raising, "It was great seeing you Rose, one last time." They stood and embraced each other.

"It was good seeing you too... my Doctor." Her mouth twitched slightly, and Sherlock was sure he saw her hands glow gold for a moment. Though, naturally, no one else besides him noticed it.

"Say, tell old pokey hair that he'd better take care of the both of you. Though I know he doesn't need to be told that, but I feel like it's something I'm supposed to say." The Doctor said, smirking.

"Yeah. Sure. And, if you ever see him, can you tell Mickey I said hi? Actually... Just tell him everything." Rose said, looking down and the Doctor nodded. Then the rest of the group bid their farewells to Rose Tyler, and they turned to walk away.

...DOOWEEWOO...

Back at the TARDIS, there was a letter stuck to the door.

"Uh, Sherlock... I think this is for you." Rory said, handing off the paper, "And Doctor, when will Amy and I switch back?"

"All in good time, Rory!" The Doctor rubbed his hands together as he stepped into the box.

"I can still hear her..." Sherlock said.

"Good, that means she likes you now! Fear not, I can hear her too. I don't think she'll switch our minds again any time soon."

"Wonderful, I'd rather not have you head butt me again." Sherlock threw himself down onto the steps in the console room and John sat next to him, smiling. The Doctor began pulling levers and pushing buttons, River joined him.

"You know, you could always travel with us." Amy said to the two flatmates.

"While that sounds extremely not boring," Sherlock started, "We've got a consulting criminal to catch." He shook the letter. The Doctor ran up to him and grabbed the paper.

"Ah, well then! To your universe it is!" The room shook, and after what felt like a small earth quake it stopped, "Now, if I've got this right we should be..." The Doctor pulled down the screen, "Ah, Yes. Exactly where Mycroft said he'd be."

"We're at Moriarty's hide out?" John asked, popping up and checking the screen, "That's gibberish... Circles and lines."

"Gallifreyan, my dear Watson." The Doctor laughed, "Space time coordinates, but I can assure you, we're in a broom closet of an abandoned building he's holding up in." River opened the door and peeked out.

"It seems safe enough." She said, turning back to the group.

"Nothing's ever safe when that lunatic is involved." John answered before stepping to the doors. Sherlock stopped him from exiting the TARDIS.

"Look, Doctor... While I'm grateful to you for bringing us here... I think I'll just give his location to Mycroft..." Everyone stared at the detective.

"You... You're passing up the change to catch him yourself?" John asked, in awe.

"Yes. I've already dealt with one Moriarty today... I don't think I'm quite ready to handle another." He smiled sadly at John, "It's too much of a risk... He's out for blood, and not just any blood." Sherlock's voice faltered.

"My blood." John finished.

"Well alright, to Mycroft Holmes, then." The Doctor exclaimed as they closed the doors and took off. Sherlock's phone began buzzing incessantly.

"17 new messages from Lestrade." He yawned.

...DOOWEEWOO...

There was a light knock on Mycroft's office door.

"Do come in Anthea. We've discussed this." Mycroft chimed, the irritation apparent in his voice as his day had just begun and already he had to threaten the leaders of several major countries. The door opened and Mycroft looked up from his papers, his eyes widened in surprise, "D.I. Lestrade, to what do I owe the pleasure?"

"Uh..." Greag cleared his throat, shuffling into the office, closing the door behind him, "I was just wondering if you've heard from your brother lately? He hasn't answered any of my texts."

"I saw him a few days ago. He was with a group of people experimenting on an old police box. I'm sure he'll turn up soon. What's the case? Another Watson look alike?" He stared at the man who was still standing, "You may sit down, you know."

"Thanks." Greg sat awkwardly in the chair in front of the elder Holmes brother's desk, "But uh, yeah... It is... Except this time... Well this time he not only killed someone who looked like John, but he killed three others." Lestrade shifted uncomfortably.

"Someone who resembles yourself and Mrs. Hudson, I presume?" He clasped his hands together under his chin as Greg nodded, "And the third?"

"Business man, late 40's, sharp suit... Umbrella..." He glanced toward the door at Mycroft's own umbrella.

"Ah. Well it would seem Moriarty has mistaken a blood relation as someone that Sherlock actually cares about."

"Now now, Mycroft..." Sherlock stepped out of seemingly nowhere, "You should know I care about you. At least enough for a threat against your life to be... Oh number three on my list? No... Top 10 definitely." They turned to him, surprise written on their faces.

"Where did you just come from?" Lestrade exclaimed.

"Oh yes, sorry..." He turned around, "You can make her blue, Doctor."

"Make her blue?" Mycroft repeated, his eyes taking in every detail they could. Suddenly the TARDIS appeared in front of them. John stepped out and stood next to the detective, he looked at Greg.

"Oh no! Don't tell me you two are together in this universe too!" He exclaimed, "Does that mean Mycroft is going to improve his personality?"

"What?" Lestrade stuttered, he cleared his throat, "I-i was just here..."

"Gregory came to ask about you, Sherlock." Mycroft interrupted, "While I'm sure the Detective Inspector would make a very excellent lover, he and I are not 'together', no."

"Did he just... Say that... Greg would be..." John stammered as he and Sherlock watched the D.I.'s cheeks flush red.

"Alright, enough with the nonsense!" The Doctor shouted, stepping into the office, smiling and thrusting his hands toward everyone, "We've got a lunatic to catch!"

What a nice and fun chapter to write. Yay!
