Chapter 10

Sherlock and the Doctor caught the next cab they could and hurried on back to 221b Baker Street. Amy sprinted back to St. Bart's and saw that everything was already chaotic. In such a short span of time, Prisoner Zero found its way in and caused destruction. People and staff were on the street, but the police hadn't arrived just yet. Amy found Molly standing alone watching the commotion.

"Molly!" Amy grabbed Molly's shoulders.

"Oh! Amy! We can't go in. Something's happened," Molly was surprised seeing Amy.

"We need to go in," Amy pleaded. "Can you please get me in there?"

"I don't...," Molly saw the desperation in Amy's eyes and decided to help. "Follow me, we can get in through the back."

"Thank you so much, Molly," Amy smiled and followed her. "We need to get into the coma ward. Is that possible?"

Molly nodded and opened the back door for Amy. In the other dimension, Rory, the Doctor, John, and Amelia were walking the halls of the quiet St. Bart's with the transdimensional interflux beaming tracker on in order to find Amy. A few doctors and nurses gave them weird looks, but the psychic paper did the trick when security ran into the troupe. All of a sudden the TIBT began to beep wildly and the Doctor jumped into action. They all ran down the hall and the Doctor sonic-ed the lens. They all watched as Amy and Molly ran past them.

"Amy!" Rory yelled out for her.

Amy stopped dead in her tracks and Molly stopped as well, "Rory!"

Amy ran towards the lens and Molly stood there in confusion, "Amy, what's that?"

"Right, time to explain a little something. I'm not the Amy that you know. The Amy you know is right there," Amy pointed to Amelia.

"I'm sorry?" Molly stood there as Amelia waved to her.

"Doctor, Prisoner Zero is here. In the coma ward," Amy explained, giving Molly a chance to digest that information.

"Where's Sherlock? The Other Doctor?" the Doctor asked.

"Preparing the virus," Amy told him. "Should be ready soon. Molly's going to bring me to the ward."

"Pond, be careful," the Doctor warned her. "You cannot predict the actions of Prisoner Zero. You're not repeating the past. You're creating an entirely different future."

Amy looked through the lens at a very concerned group of people. Molly walked behind the lens to try to understand what was happening, but it only confused her more. Back on Baker Street, Sherlock and the Doctor got out of the cab and ran up the stairs. Sherlock opened the door to see John, still in his wedding attire, sitting on his couch with his phone pressed towards his ear.

"Sherlock!" John angrily got up from his seat, advanced towards him, and punched him in the face. "WHERE THE HELL IS AMY?"

Sherlock reeled back and recovered from the punch, "John, we don't have time. If you haven't heard, the Earth is going to be incinerated in minutes time."

"Sherlock, I haven't had time to think about anything else. I've been sitting here waiting for Amy. Now, where is she?"

"She's ...," Sherlock stopped when the Doctor interrupted.

"Sorry to bother, but laptop? Where is it?" the Doctor asked.

"Over there," Sherlock pointed.

The Doctor quickly walked to it and began to pull up the video conference. Sherlock pushed past a fuming John.

"Sherlock, I'll ask one more time, but you better answer. Where is she?" John turned around and forcibly grabbed onto Sherlock's arm.

"She's fine. I'll get her back to you," Sherlock looked back at John quickly.

"What is that supposed to mean?!" a flustered John yelled. "And who is that?"

"He's the Doctor. He's ...," Sherlock was about to explain, but the Doctor interrupted.

"Ah, and here they are. NASA, Jodrell Bank, Tokyo Space Centre, Patrick Moore," the Doctor smiled and showed his psychic paper to them through the webcam.

"Patrick Moore? NASA?" that caught John's attention. "Are you hacking into a call? You can't just hack in like that!"

"Can't I?" the Doctor chuckled. "Hello, everyone!"

"Prisoner Zero will vacate the human residence, or the human residence will be incinerated," the Atraxi's voice boomed over London and this time John heard it.

"Are you serious?" John opened the window and looked outside at the sky and the crowd of confused pedestrians. "What the hell is going on? Could this day get any worse?"

The voices coming from the call began to debate with the Doctor, but he began to input information that deemed him to be quite the genius. From Fermat's Theorem to light travel, he certainly got the attention of everyone around him. The Doctor took out Sherlock's phone and began typing the virus explaining why at the same time.

"Okay, I'm sending this to all your computers. Get everyone who works for you sending this everywhere. Any questions?" one of the experts doubted the functionality. "It's a reset command. That's all. It resets counters. Clocks, calendars, anything with a chip will default at zero at exactly the same time. But yeah, I could be lying, why should you trust me? I'll let my best man explain."

There was silence, and the Doctor looked at Sherlock. John stood there with his arms crossed. He lowered the laptop screen.

"Sherlock, you're my best man," the Doctor looked at Sherlock earnestly.

"Your what?" Sherlock was taken aback at the comment – anyone would have considering the amount of time they were in each other presence.

"Listen to me. In ten minutes, you're going to be a legend. People will know your name. You'll be at the top. But first, you have to be magnificent. You have to make them trust you and get them working. This is it, Sherlock. Right here, right now. This is when you fly. Today's the day you save the world," the Doctor gave Sherlock a pep talk.

Sherlock looked at a very perplexed John and back at the Doctor, "why me?"

"It's your laptop. Now go, go, go!" the Doctor stood up and basically ran out of the flat.

"It's not ...," Sherlock tried to yell out to the Doctor, but he was gone before Sherlock could explain that the laptop he was using was John's.

Sherlock took a seat and was about to open the lid before John stopped him, "Sherlock, explain to me what's going on right now."

"We haven't got time. We have less than ten minutes," Sherlock looked at John.

"Then you better talk quickly, then," John placed his hand flat on the laptop lid.

"An alien convict called Prisoner Zero is hiding in St. Bart's, and if it doesn't turn itself in, the world will be incinerated unless we spread around this virus that the Doctor, also an alien, has created. I'm not sure how it's going to work, but Amy – a different one – and the Doctor think that it's going to defeat Prisoner Zero," Sherlock spoke in record time. "Amelia has been switched with an Amy from a different dimension, which is why there was no wedding today, but I promise you that I'll get her back. But if you don't let me do this for the Doctor, the world is going to end before I can get her back."

John hesitantly lifted his hand off the lid and nodded at Sherlock, "I'm not quite sure if I believe you just yet, but I'd rather not gamble on the fate of the human population, especially with those things broadcasting out there."

"Oh, just you wait and see, John," Sherlock smirked and stretched his fingers.
