"I Know!" Sherlock said excitedly one morning. "Let's catch a flight over to London."

"Okay," John spoke uncertainly. "What for?"

"No Idea actually." Sherlock responded. "Just might be fun, might actually work."

"Right." John said. "Why not, got nothing better to do."

"I could beat you at Go Fish again instead." Sherlock offered.

"No, no." John said. "Let's just go."

"Good." Sherlock said "I already have the tickets."

"And when were you going to tell me?" John asked.

"I did just tell you." Sherlock replied. "Let's go."

John followed Sherlock out of the Brownstone and into a taxi. He felt a great deal of Deja vu and found that he was thinking about his Sherlock. He shook the thoughts away and focused at the task before them.

About two hours after John and Sherlock had left, Jack, Joan and John's Sherlock appeared in the living room of the brownstone. Joan instantly ran around it searching for Sherlock.

"I don't think he's here." Joan said.

"Am I supposed to believe that there is another me and that we're in a different dimension?" Sherlock asked in disbelief.

"Yes." Jack answered as he looked out the window. "I can say for certain that we're not in London anymore."

"Where are we?" Sherlock demanded.

"New York City" Joan informed him.

"Not even anywhere civilized." Sherlock muttered.

"Hey!" Joan exclaimed.

"What?" Sherlock asked innocently. "You expect me to believe you Americans are civilized? Please, like anyone would ever fall into that conclusion."

"Oh stop acting like a child." Joan told him.

"Me, a child?" Sherlock fumed. "Well you're an intolerable woman!"

"Oh am I?!" Joan asked angrily.

"That's enough." Jack interrupted. "We need to find out where the other Sherlock is. There can't be two in one timeline."

"What are you saying?" Joan asked.

"If we don't get out of this time line, one of them is going to either die or disappear. The universe will find a way to fix on its own." Jack explained.

"You're both insane." Sherlock muttered.

"I'll call him." Joan said. She dialed a number on her phone and waited. "Oh thank God, Sherlock where are you?...What?! Why did you do that? So you've met John? That's good, but you need to come back here with John as soon as you can."

"Where's John?" Sherlock demanded.

"They're in London." Joan answered

"Tell them to wait there." Jack said. "I can get us to London faster than they can get back."

"Sherlock, stay put." Joan told her Sherlock over the phone. "We're coming to you."

In London, John had found a rather unpleasant person who was definitely not his Sherlock, living in 221b Baker Street. So he and the other Sherlock had found a nice coffee shop to hide out in while waiting for a new plan. It was starting to get dull when Sherlock got a call.

"It's Joan." Sherlock said before answering. "You're back aren't you...I'm in London. Well, John and I had a plan. Yes, he's a really nice guy actually. Right...Okay."

Sherlock hung up and stared at the sky for a minute before turning to look at John. Not knowing what to do, he just shrugged his shoulders.

"So, what's our new plan?" John asked.

"We stay put." Sherlock said. "Or, we could break into Baker Street."

"Let's not do anything illegal." John told him, leaning back in the chair he was sitting in.

"Right, we'll just wait then." Sherlock muttered as he slumped in his chair. John eyed him cautiously, knowing that he was going to do something; waiting was definitely not a characteristic of either Sherlock. John let out a sigh and prepared for the worst as Jack, Joan and his Sherlock boarded a plane.
