Sherlock found he was having a difficult time processing what he was seeing. The laws of physics and reason-his guidelines for everything-were being flouted by this room.
Eliminate the impossible and whatever remains, no matter how improbable, must be the truth.
We can't do that here-this is the impossible!
"What infestation?" John asked curiously. He was surprised that Sherlock wasn't asking more questions-but the consulting detective was too busy staring at the domed ceiling.
"Well, it's not an infestation yet. The aliens above us are Helbikorians. They're an invasive species, very difficult to get rid of once they settle."
"What do they want?"
The Doctor frowned. "...to take over, John. They enslave native species and use the planet until it dies. It is very serious, but I'm going to make sure that it doesn't happen. Okay?"
John nodded, and the Doctor joined the Ponds on the platform. While the Doctor and his companions played around with switches on the console, the consulting detective pulled his blogger to the side. "Are you seeing this, John?"
"Yeah. Kinda hard to miss, y'know." John smiled up at him. Sherlock was irritated that he was taking it so well. Couldn't he understand that this was not supposed to exist?
"It's impossible, John. How can it be here?"
Smiling understandingly, John patted his arm. "There are some things that can't be explained, Sherlock. This is one of them."
"Yes, but how, John?"
"How what?"
Frustratedly, Sherlock threw up his hands. "How am I supposed to process this? It's not like I have a "Impossible Objects" file tucked away somewhere!"
"Then make a new file," John suggested. Sherlock scowled for a second, then shrugged. Sometimes John's simple answers made sense.
The two were silent for a moment. "John..."
"Yes, Sherlock?"
The consulting detective was silent, uncertain of how to continue. Fortunately, John understood.
"It's okay, Sherlock. This is an anomaly-everything else still follows your rules."
"Most everything," the Doctor interjected from the platform. "There's a world hidden from the normal humans. Aliens, things like that."
Sherlock's eyes widened. John quickly stepped closer, blocking his friend's view of the room and the strange man. "Sherlock. You know as well as I that just because something has yet to be found doesn't mean it doesn't exist. You've said yourself that there is a possibility for the existence of aliens. Here's your proof. Once again, you were right. Does it shock you that they are more advanced then us?"
"Nothing shocks me," Sherlock said defensively. John snorted, trying to contain his laughter. "What?"
"Then I should have taken a picture when you walked in here."
Sherlock was still acting a little sulky.
"What?" John demanded.
"Nothing. Just...if there is a more advanced race, why did I have to be human?"
Throwing his hands up in exasperation, John turned and mounted the steps to join the others. Of course he wanted to be an alien now. Why wouldn't he? He found himself standing by the man called Rory. "Hello."
"Hi," Rory smiled back.
"So, are you...human?"
"Oh, god, yes," Rory laughed. "Amy and I are both human. It's just the Doctor." The two chatted for a few minutes while the TARDIS made deep grinding noises. Rory explained that they were travelling in space, then told John about the time the three travelers had been on a pirate ship.
"We're here!" the Doctor declared. "We're on the Helbikor ship. Are you ready to save the Earth? Again?"
