As soon as Maen stepped out of the Tardis, I heard someone shout something. I couldn't make out what it was, but it caused her to get back in and shut the door behind her. This was followed by the sounds of ray-guns shooting. In reflex, Maen ducked down, not knowing that the Tardis is protected against such things.
"Word spreads quicker than I thought." Maen said as she got up.
If this side of the universe is as advanced as they looked to me, I'd be surprised if word didn't get spread as fast.
"Looks like we don't have too many options, do we?" I said.
"I'm afraid not." the Doctor replied, "I can still try to make the Tardis move using its other..."
He couldn't finish his sentence, as the Tardis started shaking. It was as though an earthquake was happening. And a very brief one at that, because it was over after a mere few seconds.
"What was that?" Maen asked the same question I was about to.
Rather than give an answer, the Doctor ran to the door. Despite protests from Maen, he opened it, looked around for a few seconds, then went back in.
"Fascinating." he said.
"What is?" I asked.
The Doctor stepped aside, so to tell me to see for myself. So I walked to the door myself, and Maen followed. Upon opening the door, the first we both saw was the city. Or rather we were seeing the city's buildings as though we were looking up, rather than staring right in front of us. I looked to the Tardis' left, then behind it. Those soldiers from before were behind the Tardis. And if I was seeing this right, the Tardis was really lying on its back, and the soldiers were really carrying it.
I went back inside and shut the door: "Is this even physically possible?"
"What shouldn't be physically possible?" the Doctor questioned.
Since the Tardis, as I had gathered, had its own gravity system, it didn't surprise me that we weren't falling to the other end of the room when it was made to lay in its back. So that wasn't what surprised me.
"With all this inside it, how can anyone even begin to carry it?" I wondered.
"Size is relative." the Doctor answered, "As is weight."
This didn't make sense: "How can weight be relative?"
"What would you prefer to fall on you head? A pound of lead or a pound of feathers?" the Doctor asked, to make his point clear.
As soon as he noticed I understood (which was quite quick), the Doctor brought up something else: "However, the Tardis would still be too heavy. You'd need a crane to lift up the Tardis. Or else some exceptionally strong people."
This seemed to frighten Maen more than me: "Exceptionally strong?"
"Yes." the Doctor replied, "Makes you wonder what those soldiers really are, doesn't it?"
"I don't understand." Maen explained, "I've seen what those Storm Troopers look like under their helmets. They're all human."
"How sure are you?" the Doctor asked.
That was a fair question. The Doctor, despite appearances, isn't human either.
"Are there other races that resemble... us?" I asked.
"There is one race I can think of." the Doctor replied, "However, they are extinct, and wouldn't neat to carry the Tardis in group. One would suffice."
Before I could let that thought sink in, Maen already said: "I can only think of droids doing this. But we never managed to make them look like us."
"Droids... you mean robots?" despite me having used the word before, I had to be sure we were talking about the same thing.
"Of course! What else?" Maen sounded angry.
"You never managed to make droids look convincingly like you." the Doctor was thinking out loud, "But Darth Vader has been part of the Force of the universe for a hundred years... he may have picked up some secrets you have yet to discover."
"Wait." I just realized, "If they are indeed robots, doesn't that mean we can use EMP?"
"EMP?" Maen wasn't familiar with the term.
"Of course!" the Doctor said, "These people haven't used nuclear power in generations, they wouldn't know how to protect their technologies from electro-magnetic pulses!"
"No, wait." I just realized, "You just said it yourself, Vader may have picked up a few tricks. He may even participate we'd try that."
The Doctor thought about that. But he didn't need a very long time for that: "Then maybe we should send him a message instead."
