Chapter 12

House stated as he walked down the hall with the Doctor, "So not really a doctor and yet a doctor."

The Doctor nodded, "Basically. What happened to your leg?"

House frowned, "I thought you weren't going to ask?"

"Only if you want to talk about it."

House smiled, "Only if you're going to talk about your past. Are you actually going to volunteer that information? I know a few things you have volunteered; you call yourself a Time Lord. Your race is dead. You travel in a blue box through space and Time with a girl named Rose."

The Doctor grinned, "Actually, that's about the most people have gotten out of me in the past 900 years. I am feeling rather daring." The Doctor smirked and fished through House's pocket and pulled out his bottle of Vicodin opened it up and took a few of the pills and swallowed them.

House raised an eyebrow, when the Doctor stated that he was 900 years old but his eyebrow went even further when he grabbed his bottle, "What the hell are you doing?"

The Doctor grinned, "Feeling adventurous. I don't see what you get out of these though? They don't do a thing for me. Then again, most human narcotics don't do too much to me."

"If you must know, I am constantly in pain."

The Doctor grinned, "Really? I would have never have guessed, not with all the vitriolic words you are dripping in."

House's cane whacked the Doctor in the arm, "Ow….what was that for?"

House grinned, "As per our agreement Doctor, you get whacked when you're being rude."

The Doctor rubbed his arm, "Geeze, I get more abuse from you than I do from Jackie."

"Part of the muscle in my leg died. It became necrotic. My girlfriend didn't follow what I wanted. She had the muscle removed while I was unconscious."

The Doctor nodded, "I killed all my people. Not something I am proud of, but I had no choice. My people were at war with another race. In the end, all of them died, because of my actions."

It was like two veterans swapping pain stories for a change, a strange thing, both were either too egotistical in their own minds to admit that was what they were doing but basically that was what was going on.

"My father abused me as a kid. He made me take a bath in ice water."

The Doctor snorted, "That's nothing. Try being disowned from your family."

"Disowned, what exactly did you do to get that?"

The Doctor chuckled, "Long story. I disrupted their quaint little lives. I guess you could say I was the square peg that didn't fit into the round hole. After I was disowned I left my name with them."

"If you were anything like you are now, no wonder you were disowned."

The Doctor snickered lightly, "Kind of. I carry bits and pieces of my first life."

House frowned; he didn't quite understand what the Doctor found funny or what he meant by 'first life.'

The Doctor could see the confusion on House's face, "Don't think too hard about my past, House. It'll only give you a headache. Shoot, it gives me a headache from time to time as well. Therefore I don't really think about it that much or talk about it either."

House was still wondering about his own sanity. He still didn't believe in aliens. Just because he saw the Doctor show him all these things, he still wasn't too prone in believing. He wasn't like Chase, to let his mind accept rubbish like aliens. Maybe he was hallucinating. This just didn't seem real.

The Doctor entered the patient's room. He took a look at Julie, if she could be called Julie anymore. She barely looked human anymore. Her skin had taken on a greenish black cast, but a light faint pink still remained of her human physiology. The Doctor poked opened her eyes to see the gold colored eyes of a Xylomian. The only thing that looked human was the blond hair. The Doctor gulped, that would be Rose if he didn't figure out the problem or if he couldn't solve it.

There was one other option that he had and that was to talk to the Xylomian. After all, they were a sentient life form as well, even though they were parasitic in nature. He had to give them one chance, just one. Julie had received the full dose of the spores. Chances were that this Xylomian would be the leader, the leader of the Xylomian hive mind.

House muttered, "Her skin is dead….that's why it's blackish in color."

The Doctor snorted, "Not dead, just replaced with alien tissue."

The Doctor circled the bed and then he grabbed the breathing tube that was down Julie's throat and pulled it out. "I can't have a proper conversation when her mouth is stuffed with a breathing tube."

The Doctor threw the tube to the side and put his hand on the side of Julie's head.

House frowned, "What are you doing?"

The Doctor grinned, "Diplomatic relations, provided that the alien in this girl doesn't decide to kill me first."

"That's reassuring, if she kills you, I won't have to listen to your incoherent babbling."

"Here all this time I thought you liked me," The Doctor said in a slightly mocking and yet downcast tone of voice.

The Doctor sighed and concentrated on the alien mind that was in the girl. "Who are you? Under Convention 15 of the Shadow Proclamation, I ask you to identify who you are."

The Doctor broke his hold on the girl as the alien laughed, "I am Vaalasii, the first of many. We are the first. The Xylomian race lives again, the connection is made, my brothers and sisters may live. Who dare disturbs my communion."

The Doctor grinned, "I do…."

The alien's gold colored eyes glared at the Doctor, "Who are you, insignificant one."

"I am the Doctor."

"Doctor…ahh yes, we are in what humans call a hospital. It is what humans call their guardians of life."

House muttered under his breath something about Schizophrenia. The Doctor glared at House and told him to hush; he then turned back to the alien.

"As fascinating as that all is, self awareness I mean, I wish to make a request."

Vaalasii looked annoyed, "What does the Doctor want of the Xylomians, we are a dead race. We only wish to breed and live again."

The Doctor sighed, he knew what he was going to ask for next was going to be trouble; he took another gulp of air and spoke.

"The girl, the human girl and all the humans here, they only wish to breed and live and grow as well. You have taken over their bodies. There minds, there lives. I am asking you on behalf of the human race to let them go. I can help you. I can clone bodies for you to reside in. You don't have to take over the human race to live. I know what it's like to be a dead race. But you don't need to take over another race to survive."

Vaalasii laughed, "Insignificant one, we do not want your offer. We, Xylomians are a warrior race. We will take what is rightfully ours. This race is good for us, there minds strong, their resources plenty. We will rebuild our Empire and Earth will become the new Xylomian home world."

The Doctor's face took on a very firm resolve, "Not if I have anything to say about it."

Vaalasii stood up and walked forward towards the Doctor, "Then you will die…"

The Doctor grinned,"You know, that's what they all say to me. You sure haven't learned anything since you were last destroyed."

Vaalasii paused, "How do you know this, human?"

The Doctor laughed, "I am not human, Vaalasii. I know what happened to your people. You're a relic, a fossil, something that shouldn't even exist. My people were right to destroy you."

Vaalasii glared angrily at the Doctor, "TIME LORD….YOUR HEAD WILL BE TAKEN AND YOUR HEARTS FROM YOUR CHEST AND THEN GIVEN TO OUR GODS."

Vaalasii suddenly charged at the Doctor and the Doctor looked at House, "Don't just stand there House, do something?"

"You're the one who angered it. What should I do?"

"I don't know, you have a bloody cane, do something with it!!"

House took his cane and began whacking the creature in the head, which only made the creature angrier. House began to whack harder, and a loud sickening crunch was heard as the cane hit bone and tissue. The creature moaned and sunk to the floor wounded.

"I killed her…." House muttered.

The Doctor sighed, "Julie was already dead. And I am not so sure if that alien is dead. You may have cracked it's skull but that doesn't mean that it's completely and totally dead."

House looked annoyed, "Then what kills them?"

The Doctor grinned, "Would you believe sodium?"

House frowned, "Salt? You have got to be kidding?"

The Doctor grinned, "No I am not. My people seeded their whole planet with salt. It killed their pods and their race off. I guess one of them managed to survive. It's sort of like what the Ancient Roman Empire did with Carthage during the Third Punic War in 146 BC."

House snorted, "I thought that was a myth."

The Doctor shook his head, "Nope. I was there. I managed to save a few of the inhabitants that the Romans were going to sell into slavery."

House said, "We should kill them then. Take all the salt and sodium compounds we have and kill them."

The Doctor looked angry, "Then you'll kill the humans as well. I am not going to kill Rose, House. I have to try and save her and the rest of the human race as well. As much as I want to finish off what my people started a long time ago, I am not going to wipe out the human race along with the Xylomians. I have an idea, though. Come on, back to the TARDIS."

House groaned, "Now what?"

The Doctor gave a look that only meant, 'you'll see….'
