I DO NOT OWN BIOSHOCK, NOR ITS CHARACTERS.

Hey there :D

I've finally decided to go on and try! I finished Infinite some days ago and this idea has been bugging me since I started reading its fanfics. I'm decided to make this one long enough, but I'm not English, so feel free to dismember and correct me. In fact I would need a Beta, so If anyone's interested...

Enjoy! =)

"Rosalind?" he had just got home from a long, pleasant walk in which his sister hadn't cared in joining.

Rosalind never cared, actually. It had passed almost a year and Robert doubted he had seen her going out if it was not for business, and that seldom happened.

This time, he was decided to bring her into the sunlight. Had she ever seen her work? Her statue? Spending all her time in the labs, working... that couldn't be healthy.

"Strange..." he muttered to himself, finding the lab's door closed. "Rosalind?" he tried again, a little worried.

Where was she?

"Kitchen" was the dry answer coming from the basement.

Rosalind was sat at the table, with a cup of tea in front of her, eyes lost in the ceiling.

"Why are you here?"

"I'm bored."

"The door is closed" he said walking to her side.

What was wrong with her? She barely walked out of that room if not by necessity. That was a constant. He had found her so many times asleep over the desk that a pillow was put near just in case. So obsessed was Rosalind with her work that it didn't matter to her having the Contraption in her own bedroom.

"I know" she sighed.

"Why?"

"I'm done" she simply replied, taking the cup to her lips.

Robert understood. Rosalind tended to get obsessed with projects and, after a time of working really hard, when no result came, she would just get bored and quit it. It was unknwon if Rosalind's male counterpart was too a project, but that was a fear that Robert couldn't deny he had.

"But... we've been working so hard" he frowned, confused.

He had been able to come to Columbia thanks to a two-sided tear they had opened. Now, almost a year later, they were still trying to figure out how to repeat the result without the necessity of another machine in the wanted Universe.

"I know, dear Brother."

"Don't worry, Rosalind" he sighed, trying to comfort her with a hand in her shoulders. "Let's take a walk. It shall do you good."

"It shan't" she stood up after finishing her tea and walked to the sink. "Because I shan't be taking none this afternoon. I must talk with Mr. Comstock."

"What for?" he demanded, a little angry at her.

Robert had started to notice half a year ago that she was indifferent to almost everybody. Few people had seen her tender side of a woman, and Robert was not one of them; Comstock and Fink had. Rosalind would be specially cheery around them, enthusiastic even. Kissed them in the cheeks for a greeting, smiled at them. Robert, in the other hand, had seen her. Rosalind didn't seem to care for anyone except for her beloved Brother, and still she would be quite cold and short in her speak. Maybe because she was accustomed not talking to anyone. It was just her. She needn't to show any façade with him.

And still, it annoyed him so much to see his female counterpart so coldhearted. A smile, a shared thought was all Robert was asking for.

"The Contraption."

"We could still go out when you get back..." he offered with a sad voice, not even looking at her.

Rosalind noticed that. She knew how difficult could be to live with herself, for she had experienced it living with Robert. She could see how her temperament affected him. Robert was the only man capable of understanding, a like-minded person she had dreamt about meeting for such a long time... But there were things he couldn't possibly be aware of, such the Contraption's meaning to their lives. Rosalind was so tied to the dark secrets that surrounded Columbia that was afraid of telling him. She didn't want him to leave. She needed Robert by her side. Just his presence would calm her enough to keep working.

And he didn't even knew how much did he calm her.

It was his wish, and she had been denying it for a long, long time now.

It was not fair.

"Fine" she replied, much to his surprise. "A little evening walk can do no harm, can it?"

Robert waited patiently in their parlor, trying to ignore the closed laboratory. His curiosity was trying to push him to open the door and see what was upsetting her Sister. Rosalind could be cold to him, but all Robert wanted was to fix it so she could finish it and spend more time exploring their differences.

Painting was all he could do in such a state. It made his mind to fly away and attached his body to the canvas, so no silly thing could happen.

Just wait for her. Out in the street, she'll tell you.

Robert was so excited. He couldn't believe it was finally happening! His beloved Sister out in the street with no purpose but to enjoy herself. Rosalind needed to learn how to do that; enjoy things. He would teach her, Robert decided. Then maybe she'd be more open with her thoughts. They'd learn from each other, share a proper living identity like it should be shared.

The clock was striking seven when Rosalind appeared. Robert was already waiting in the hall.

"How did it go?" he asked politely, not wishing to change her mind on the deal.

"Not fine" a sad smile she gave him. "He wants to see it. I told him the Contraption was not ready. Still, he wants me to show him."

"Ready for what?" was the right question. A frighten look conquered her usually indifferent-to-everything eyes.

"Nothing" Rosalind was already half up the stairs.

"I thought you were going out with me tonight" Robert pointed the door, trying to ignore her too quickly Nothing.

"I'm tired."

Now, he was annoyed.

"Is tired, was tired, will be tired" he spat. "I'm here for you everyday, I work as much as you do, I love science as much as you do for we are and not the same person. You won't even tell me what is going on and I'm fine with it! I just want to get you out there to show me the wonderful things you have created, to remind you that a little joy is good for work too. We made a deal, Rosalind. Now, if you're going to be a sore partner, then I shan't do this again."

"Now, that sophistry" she said without thinking.

Suddenly, Robert's looked worried. He started climbing the stairs to her.

"Rosalind, are you alright?"

"Yes, why?" she frowned.

"Your nose... It's bleeding."

"Nonsense; that's impossible" but there was the blood in her fingers when she touched her mouth.

"Rosalind!" she heard Robert cry just before everything went black before her eyes.
