A/N: Right, well this is set sometime during season six. It'll probably be mostly AU after the Wilson episode since I live in Australia and they haven't shown any past then. I have gotten a little bit of extra information from Wikipedia but not much.

I've already done a few chapters and I don't think these first few are very good. But I think it gets a little better later on. Obviously, this is only the first chapter.

Also, I was wondering what pairing would be preferred. I love all Thirteen pairings (except for maybe Cuddy/Thirteen) but I was leaning towards Foreman/Thirteen and Chase/Thirteen for this one. Which is most liked? I would definitely like some input.

Enjoy.

"I'd learned that some things are best kept secret."

Nicholas Sparks (Dear John)

House frowned in concentration as he deftly worked his way through the contents of the object in his hand. It had to be in here somewhere, that one piece of evidence he was looking for. Not that he really needed to find it to know he was right but it would make things more fun so that was enough incentive to continue. Plus, Cuddy was searching him out for clinic hours (she really should have learned to just give up by now) so as long as he remained in the girls' locker room he was relatively safe – she would never think to look for him in here, not at first.

His hand closed around something just as a voice broke into his thoughts; an angry voice by the sound of it.

"What the hell are you doing in my bag?"

"Ah, got it," he commented, ignoring her as he pulled out the pill bottle in his hand. He turned back to face an indignant, not to mention furious, Thirteen. "You're pregnant."

Her eyes widened even more, this time in disbelief. "No I'm not." The look on her face clearly suggested that she thought he was crazy. The woman was a reasonably good liar but certainly not good enough for his standards.

"For the past week you've been raging around like a bull in china shop, liable to bite anyone's head off at a given moment. Chase is still shaking in his boots from when you blew up at him yesterday."

Thirteen placed her hands on her hips, clearly not impressed. "You're exaggerating, I haven't-"

He cut in, not caring about her excuses. "Also, your breasts have gone up a size," he stated, eyeing the anatomy pieces in question. He was sure he wasn't the only one who had noticed this fact either, he'd caught Foreman staring the other day, Chase too. Even Taub hadn't been immune when she'd dropped her clipboard and bent down to pick it up.

She crossed her arms over her chest, blocking his view, and glared reproachfully at him. "You're unbelievable."

"You also refused the wine Taub brought in for Thanksgiving." That incident had gotten raised eyebrows from everyone – It seemed that Thirteen would be the last to refuse a drink.

"That's all you have? All those things can be rationally explained, House, I am not pregnant."

House nodded his head, pretending to consider that. "You're right; all those things can be explained. Except-," he paused long enough to toss the bottle of pills at her and she caught them promptly, turning them over in her hand in disbelief. "-prenatal vitamins."

She closed her eyes for a moment, breathing out. There was no questioning the fact that she was caught and they both knew it. Sighing, she placed the vitamins in her pocket and stepped forward, snatching her purse out of House's hands. "Well done, you figured it out. Now go."

House ignored this and watched her carefully as she turned and opened her locker. He'd been expecting more of a fight and was quite disappointed with her reaction. "Does Foreman know?"

She refused to look at him. "Who says it's Foreman's?"

"Who says it's not?" he quipped before turning serious again when her shoulders stiffened in agitation. He nodded towards her stomach. "Judging by the protrusion of your lower abdomen you're about three months along, if not more. So unless you were cheating on Foreman . . ."

"I didn't cheat on Foreman!" she snapped before he could continue that train of thought.

House nodded, already expecting this. "Fourteen's going to have a baby," he concluded simply.

She stashed the bag violently in the back of the locker. He heard a smash and resisted the urge to wince; he was feeling particularly sorry for her cell phone right about now. "No. No, they're not because I'm getting an abortion."

He eyed her closely for a moment, weighing up her words. "No you're not."

She turned to face him incredulously. "Excuse me?"

"You're too much like Cameron; you care about things too much. Besides, the fact that you're at least three months pregnant by now tells me that you've already grown attached to it. You've been putting it off. Which means you'll never go through with it."

"That means nothing. I'll go through with it because I have to. I'm not ready for a baby; I'm in the middle of a fulltime career, I just came out of a serious relationship and I'm currently dying of Huntingtons. I am not bringing a baby into this."

"You say that because you're trying to convince yourself that it's the right thing to do. It's noble but ultimately you won't go through with it."

She fumbled around in her locker, avoiding his gaze. House had a feeling she didn't even know what she was looking for in there. "It has a 50% chance of getting Huntington's like me. I'm not going to put someone else through this."

"Yeah, but you know there's tests you can get to find out whether that little bundle of joy is going to turn into a Minnie Thirteen." He eyed her closely as she continued to avoid his gaze. "Unless, of course, you've already taken the test and it came back positive."

Still no response which, in his opinion, was answer enough. Well, this changed things. If it had just been the other reasons that were convincing her to get the abortion then she wouldn't go through with it, and she'd be happier because of it, but the Huntington's chorea was just something that she couldn't excuse. The woman couldn't even play the card well-there's-a-50%-chance-that-it'll-be-fine-so-what-the-hell since she'd already taken the test.

Thirteen had been backed into a corner and she was acting appropriately. The only problem was that she wasn't at all happy with the decision she had made. It was easy enough to tell from the tone of her voice and the defensiveness in her posture.

"You're not going to tell Foreman?" he asked after a pause in which Thirteen remained silent, staring into the inside of her locker with a blank gaze.

"No. Is there any reason why I should?" she asked, slamming the locker door shut.

House cocked his head to the side at that one and resisted the urge to roll his eyes. "Well, not that I care, but he is the baby daddy. It's considered basic etiquette in most cultures to inform the baby daddy that there baby's going to be, you know, terminated," he told her with a 'duh' face.

Finally, Thirteen turned to look at him. "It's not a baby yet, just a foetus, a clump of cells, whatever you want to call it, but it's not a baby." She brushed past him angrily and House sidestepped out of the way just in time to avoid being hit in the face by a bundle of frustrated dying young doctor. "Besides, it's better if he doesn't know."

She could be right, House allowed. Foreman was an idiot when it came to her so it was probably the better idea not to involve him. The better idea, for sure, but certainly not the most interesting one. And, after all, what was the point if not to be interesting?

A/N: To be honest, I don't know whether they actually have prenatal tests for Huntington's chorea but let's just say for the sake of this story that they do. I'm pretty sure you can anyway.

I know it's only short and I don't think I really captured House's personality very well but I hoped you liked it anyway. This is probably the worst chapter I've done so far so let's hope the next one's better.
