"Guess that means we're going to have to be more hands-on, just like old times! Pity though, having a sonic screwdriver makes it so much easy. Should have a back-up, must remember that in future."
"What about your back-up? You're here, isn't there anyone with you?"
"Uh. Humans. We're stuck on the moon, running out of air with Judoon and a bloodsucking criminal and you're asking personal questions. Come on."
They followed The Doctor down a hallway, House, who was right behind The Doctor, turned to Wilson and Cuddy with glee in his voice.
"Hear that! He really is mental, doesn't just go around saying he's an alien but alludes to it as well! Nutcase!"
They turned a corner just as House finished, to step in front of a Judoon that scanned The Doctor.
"Non-human."
"Holly crap!"
"And again!" The Doctor turned and pushed the others back the way they came. The first room they got to they were pushed in and the door was locked, by hand.
The three humans stood in silence watching the alien search his pockets, pulling out more stuff than could possibly fit in them, including a yo-yo and several items that looked like cat-nip.
"Hold on, hold on. Aha! Found it, knew I had them somewhere."
The Doctor marched over to the table and dropped a handful of metallic and organic bits and pieces and started to work.
"So you're an alien? For real?"
"Yep," the answer was slightly muffled as he had some sort of tube in his mouth.
"But you look human." It was more of a question than a statement, Wilson couldn't decide if he wanted an answer or not.
"So do another thousand alien species. Ever thought maybe you look like me?"
Wilson and Cuddy had to sit down, House didn't seem at all fussed by such a find.
"What are you doing?"
"A while back I got bored, started making another sonic screwdriver, a better one. Luckily I kept the parts on me but I don't have enough to make any of the new settings I had planned."
"So it doesn't just make that annoying noise."
House's sarcasm seemed to not have any effect on the alien at all.
"I find it soothing, sort of. And yes, it does more."
Silence reigned until the alien suddenly jumped to his feet, pleased grin on his face and sonic screwdriver in his hand.
"Now if I just…" He twisted the tube until it made the right buzzing noise and then pointed it at himself.
The others stood in the room wondering what the hell he is doing.
The sonic was clicked off and The Doctor pressed his ear against the door until he found what he was listening for. Quick as a flash he whipped open the door, shoved the screwdriver out and turned it on the Judoon for a whole two seconds before putting it back in his breast pocket and shutting the door.
Turning to the other occupants of the room he had a huge grin on his face, looking as if he just found the cure for everything and slightly smug about it.
"There. Should be safe now. Programmed my DNA into their technology temporarily so it won't recognise me as non-human. Brilliant!"
"So what do we do now?"
"We find the plasmavore. What's she doing now? She's still not safe. The Judoon could execute us all. Think, think, think. If I was a plasmavore surrounded by police, what would I do?"
The Doctor turns on the spot, thinking hard. He spots the MRI sign, "Ahh. She's as clever as me. Almost."
