Jiina seemed happy that he had chosen to join her, watching him get comfortable with a bright smile on her face. Tao was nervous about sitting there with her. She was someone important, very important and he was... well, he was nobody. Who knew if or when she would turn back into the angry woman he had met in the clearing? He was going to be the one taking the blame and the punishment.
He managed a smile back, just as stiff and awkward as he felt, but at least it was an attempt at reciprocating her own attempts. Faking calmness and happiness were two things that he was well practised at if he had the time to prepare himself, but it became strained when he was put on the spot.
I can't screw this up. Was the only thought running through his head. I can't make her angry.
Jiina seemed embarrassed by her own attempts to figure out the code, tossing the paper to the ground, out of sight and mind. While she hadn't brought any more paper with her, she had not used her napkin, and that was better than having nothing at all. He accepted it and the pencil with a nod, putting it down in front of him and studying the code once more.
While his new companion turned herself back to the no doubt ice cold meal she had bought, he began writing on the napkin, hoping that it would be as easy as he first thought.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
He turned to show the beginnings of his work to Jiina, though he wasn't sure if she was paying attention or not. “These are the twenty six letters in the Common alphabet.” He explained, deciding to stick to Lhavitian for a while longer. She hadn't much liked Common, if he recalled. “The way that your code is ciphered is simple. These letters have been substituted with the other letters.”
Turning the napkin back towards himself, he began to quickly shift through the alphabet. It was a simple trick; all one had to do was take each letter and switch it out for the letter a certain number of spaces behind it. He had done quite a few of them before, and it was an easy thing to test.
First line: Jx tbsayqho Ecckb
Shift = 1 Shifted: Iw sarzxpgn Dbbja
Shift = 2 Shifted: Hv rzqywofm Caaiz
...
Jiina asked him a question, startling him from his attempts, so far unsuccessful.
“I, er, yes, I do.” He said, after taking a moment to sort through what she said in his head. “I... well, I grew up quietly. I used to do these for fun.”
And hopefully, you won't take that as badly as you took what I said about the stars. He added silently, finishing out the rest of the shifts in the meantime:
...
Shift = 24 Shifted: Lz vducasjq Geemd
Shift = 25 Shifted: Ky uctbzrip Fddlc
So, it wasn't anything as simple as a shifted cipher. That made things more difficult, because after that, it could be keyed, or perhaps each letter had been randomly assigned. That could take hours to decode if it were the case.
A waitress had approached the table, bringing a bottle of wine and two glasses. Jiina must have ordered them when he had turned back to the shifts. He started to protest (didn't she know how expensive wine was from the Fleeting Comet?! It was practically a day's work!), but she didn't seem to want to take no for an answer.
So, he nodded his thanks mutely and accepted the drink, even taking a sip to be polite. The flavour was much stronger than what he was used to, which usually was more water than alcohol. He swallowed the mouthful quickly and put the glass a little out of the way.
“Uhm...” He waited until Jiina's glare had scared away the waitress to a safe distance. “Well, I attempted the easiest decoding method I could think of, which was just to shift through the alphabet. It's, uhm, like, assume that a is equal to 1, and b is equal to 2, and so on? Then you add a number to that like 1, and then a is equal to 2 and b is equal to 3. That means that in the code, any 'b's would actually be 'a's... all the way until all the 'z's would be 'y's and all the 'a's would be 'z's.”
He was beginning to ramble, a little flustered at having to explain how it all worked. He wasn't even sure if he was making sense. “A-anyway! You don't have to worry about that, because I just tested all 25 shifts and none of them work. It's probably a little more complicated than that.”
He brought his attention back to the first thing he had written; all the letters out in a row. “It seems like all of the words are still intact, so... well, we can try and figure out which letters are which manually. It's more tricky, but it might give us a head start on how it is encoded.”
Taking the original code, he pushed it towards Jiina. “The code is from your father, right? That means that there should be words that are familiar in it, like a name or something like that. Can you see anything with the same sort of... structure?”
