"Let's find out. Come on, any balcony's around here?"

"Yeah my office and his, Wilson's is closer though. Can't help wishing Chase was hear right now."

House took on a wistful look to which the patient could not fully comprehend. He didn't miss Chase at all, he just seemed to say so in order to provoke his friend. Sadly his friend was too busy gaping at what was outside the window to comment.

"Chase?! Anyway, lead the way, Allonsi!"

As they stood on the balcony, taking in the landscape House decided it was too quiet.

"What'd you say your name was?"

"The Doctor"

"Ohhh, definite article, someone has a God complex."

Wilson chose that moment to mumble something about pots and kettles.

"Doctor who?" "Just the Doctor" "Of medicine?"

"Wellll… Yes I suppose."

"Well don't tell them that." House pointed his thumb over his shoulder towards the patients inside the hospital running around panicking.

"They'll suck the life out of you."

The Doctor contemplated this before shrugging, "I've had worse."

Wilson decided to stop the conversation which could probably go on forever.

"We're on the moon; shouldn't we be focusing on that? Or at least something more important than names?"

"But we have to name him!" House declared, faking shock horror at what Wilson was saying.

The Doctor was studying House intently and spoke up when he noticed piercing blue eyes on him.

"How'd you know I wasn't sick?"

"It's a gift-" "And a curse," grumbled Wilson.

House was curious that the strange man actually owned up to his lie without it being forced from him.

The only problem was that he was more curious about other things, and curiosity was never left alone by House.

"How are we breathing?"

"Some sort of force-field I think." The stranger picked up a pebble and threw it, giving a satisfied nod when his suspicion was confirmed.

"That means we only have so much oxygen." It wasn't really a question, Wilson was just speculating, the only reason he said it allowed was to hear someone tell him he was wrong.

"Yup." The strange man's tone was still light but there was something dangerous about it.

"Oh look, visitors."

Three cylindrical shaped rockets/ships of some sort landed just outside the force-field. Rows upon rows of aliens in dark armour marched up to the hospital, the field letting them through with a brief flash of light around each one it submitted.

Wilson was slightly shocked at this revelation, only managing one word.

"Aliens."

"Hope they don't want to probe me."

House, on the other hand, seemed to be taking it in his stride, not letting any opportunity to be heard go.

"On that note let's see what they're up to."

The Doctor clapped his hands together and strode back into the hospital.

House, Wilson and the Doctor watched from above as patients, visitors and staff all scrambled away from the new-comers in panic.

They watch as a nurse is scanned and drawn on, "Probing isn't what it used to be…"

Wilson at least could keep his mind focused on the gravity of the situation.

"Who are they and what do they want with a hospital?"

"Judoon." The Doctor was staring intently at the people below him.

"Galactic police. Well, police for hire. More like interplanetary thugs. They brought us to the moon because it's neutral territory. Like I said about the H2O. They're making a catalogue, means they are after something non-human, which is very bad news for me."

House was listening intently to 'The Doctor' as he spoke, he seemed to know so much. The man was a puzzle, so naturally House wanted to know all about him. 'you've got the Rubik complex, have to solve the puzzle' as Wilson once stated.

What was also interesting was this guy seemed to also have this complex. His eyes were scanning the area, soaking in all available information and storing it, never stoping.

Wilson broke through House's thoughts when he asked a question with fear, awe and surprise in his voice.

"You're an alien?"

"Still better than coma-guy!"

The Doctor just looked at Wilson, not answering his question with words.

"Come on, we better move."
