This is but a work of fiction, and I don't own either the game nor a PS3 in that matter. And i also don't own the story of Final Fantasy XIII. Blame the fact that I've only got to know that these two are sisters through fanfiction!

Title of each chapter: The first word is always in latein

also I suggest you guys to listen to ''Aimer – Rokutousei no Yoru'' while reading this chapter!

Somethings should be kept a secret. And somethings should be questioned. But what will it result to...if the answers and the secrets were never the same? Lightning. How fitting and ironic that the name she gave herself was the one thing that seperated her from her love. To even come in terms with her emotions and to overcome the hurdle that is: Sisterhood. When she first started her journey, she would have never expected to fall for the one person she should have never fallen for...but that didn't matter now! Now that the one she loved was in danger, all she should think of was the nearly invisible wall of lightning right before her.

''Why! Why are you so unable to see what lays ahead of you! Why!''

Loud voices pierced her ears, soft touches reached her consciousness waking her. Her still closed eyelids began to part. She slowly opened her eyes, making out her sisters from the blurry gaze she had after waking up. Blinking a few times she looked over to her wondering what the problem was. ''Serah! You know how late it is?'' Clair complained at her younger sister, but was shocked to find the girl crying, while she squeezed her favorite teddy bear tightly. Clair knew instantly that something is wrong and quickly engulfed her sister with her whole body. Serah really needed a big hug when she is sad or when she cries. Because of the bear hug her older sister gave her Serah pressed her own body firmly into that of Clair.

Both sisters shared their bed for three months now. It started with Serah's constant nightmares and Clair decided to become her guardian whenever her little sister wanted to be held tightly. But a while ago they had a fight about the sweets Serah eat, which Clair exclaimed as her own and in an unfavorable moment Clair screamed at Serah that she will sleep alone from that day onwards. That night Sarah couldn't sleep, to afraid what she might dream about. She was so scared and cried silently, so she had to ask her parents if she could sleep with them that night. She didn't dream about anything scary that night, but she didn't feel as secure as when she sleeps with Clair. When she woke up she had an unpleasant feeling between her legs, apparently her parents noticed that something isn't right and woke up, only to find a sobbing Serah,sitting on a dark spot which got larger on the white sheets…

When Clair got to know that Serah wet the sheets, a ping of guilt crawled into her heart. The whole day over she tried everything to cheer Serah up, which only ended in the opposite. On that night Clair coaxed their father into telling their favorite story the tail of Lighning the Knight protecting those he loved…and since that night Clair never left Serah's side.

But now something was disturbing her little sister ''Serah what is wrong? Did you have a nightmare again?'' she didn't say anything but shook her head ''No…I-I heard screaming…and then someone…someone ...*hick*'' she began to cry once more and all Clair could do was holding the girl and telling her that everything will be okay.

They sat there for quite some time and the noises from downstairs were getting louder by the second. Serah couldn't stop crying, her tiny body began to tremble and from her mouth came strangled screams. Through all that Clair could do nothing but hold her sister. She felt Serah shifting in her arms, so she loosened her arms a little.

Both sisters were now facing each other.

''Clair?'' a soft whisper, barely audible ''Hmm?'' but still Clair could hear what her sister said ''What is going on?'' her sister asked unsure, uncertain, frightened, that question answered to all questions of Clair…''I'm not sure Serah'' she trembled even more at what the older one said ''but I'm sure that…that'' what should she say? How can she make her sister fell better? What in the world was going on? Who was the person who screamed through out the house? 'How can I make Serah stop crying? I don't like it when Serah cries…I don't like it one bit!' then she remembered…

'That promise I had with Papa…'

''Serah'' she looked her sister into her clear blue eyes, those eyes which held a gaze that said 'Let it stop'. She slowly breathed in and breathing out, never breaking eye contact with Serah. Clair's eyes held a different expression then before. The younger one was stunt by the look her sister had, so much confidence was in them. She might not have known what it meant but she somehow understood what Clair was going to say to her…because Clair's eyes would always foretell what she will say. ''Serah'' asking once again to get the attention from her younger sister ''Hm-n''.

''No matter what happens, I will always protect you…and only you'' and Serah stopped crying.

Clair didn't realize, or couldn't have known, that those words of comfort and the promise they held would change hers and her sisters fate…forever.

''THATS IRRESPONSIBLE!'' the scream came from the other side of the bedroom, startling the sisters just as they got comfortable enough to finally go back to sleep. The stair-bars creaked from the weight of someone. Frightening loud steps came closer to their room. The doorknob was forcibly turned but the wooden door wouldn't open ''DON'T YOU DARE DO THAT TO MY DAUGHTERS!'' a female voice screamed. Their mother. Loud rumble noise were coming from the other side of the walls, Serah pulled herself farther into her big sisters chest, holding for dear life onto Clair's shirt. Many things happened simultaneously, Serah crying into Clair's chest, Clair holding her little sister in her arms trying to cover her ears, so that the noises from outside wouldn't reach her.

I truth she was just as afraid as Serah, but even without the promise she made, she swore to protect Serah no matter what! If could see his daughter, maybe he would cry from the joy of knowing that his daughter Clair was protecting her younger sister with vigor, keeping their promise…

The slamming against the door and at the walls continued, the person out there was frightening Serah, that was all Clair needed to know. She stood up together with Serah ''Clair! Don't…'' those words hurt and stopped her. Not because of that iron grip her sister had on her. But because of the pain she felt within her heart…whatever, whenever, no matter who…no matter why ,all she could focus on now was her hurt sister. Serah wasn't hurt physically…but still…whoever made Serah cry was going to get a beating.

Whenever Serah cried, Clair would cry with her and would then try to cheer her up. And when she can't do anything for a crying Serah, then something within her began to scream.

'No one dares to make my sister cry!'

But in the moment when Clair wanted to tear her sister away from her to kick -whoever made her sister cry- in the butt, a loud banging was heard followed by a thud ... Then the door opened. Clair looked up to whoever came into her room following the shades of their shared cupboard and looking past the outlines of all the stuffed animals.
Fear would not hold her back, but she still stiffened from the uncertainty. A wave of relieve washed it over when she heard ''Clair Serah,are you okay?'' her father was pushing the door aside, entering the room and strolled towards her and Serah. His steps were sluggishly slow and he seemed out of breath. His mouth was opening and closing, lips were trembling and a nauseous feeling was going tp form in Clair's gut. Serah when she heard her fathers voice, slowly turned so that she saw him.

In that moment he stopped.

What was he going to say?

Was there even a right way to explain it?

What can he do?

He could not stop his own tears from escaping. His children were even now more important than anything else. So there was no other way around it. He will bear it. For them and for himself…

The eldest Farron rushed over to his daughters and gave both a bear hug at the same time. His tears were falling onto their combed hair whilst both children didn't no what was going on. The hug was a little painful but neither said a word, couldn't say a word…but something felt amiss…something very important. And before her father could say a word Serah asked ''Papa? Were is Mama?''

Instead of answering he only held them tighter, not letting them go. Serah was still waiting for a reply, and that nauseous feeling was now getting to her…she was suddenly afraid, but both girls returned the affectionate gesture. Still that feeling – wasn't leaving anytime soon.

That night something happened. The sun was peeking at the horizon, warm rays of light shone through the curtains. The night was still present…that starless dark sky was slowly replaced with the new day.

But in that night…something precious and irreplaceable has…gone lost.

Clair was holding Serah's hand while they embarrassed their broken father. That feeling neither of them wanted, was still lingering in their hearts. Clair didn't want to know what happened, but she couldn't help but feel disheartened the hug their father gave him, did not held the warmth it normally held…and he was mumbling ''I'm sorry…I'm sorry…I'm so sorry…!'' like a mantra.
Then her gaze fell onto her sister, who was equally as sad as their father although Serah didn't understand what was going on…still it was just natural that when someone you love cries, you want to cry with them, and so did she too…Clair gave Serah's hand tight squeeze and swore to herself: 'No matter what happens I protect Serah'

And so they cried together, not one of the three was going to break away from the others.

All three knew…now they had only each other.

The new day began with tears…
