little bit of an explanation for a detail in Doppelgänger

Dan stared at her hands, holding the pen as she was waiting for his answer. To tell the truth, he couldn't recall the question, but it had to be something Maths-related, but right now, his thoughts were somewhere else.

"Dan!" the teen kicked his leg under the table.

"What?"

"Are you helping me or not?" the half-ghost asked, meaningfully with crying out tone. "You offered me, so help me." she reminded him, hitting frustrated against her fingers the pen.

Dan reached out, grabbing the fastly moving object, measuring it, hearing by it her sighing satisfied, but against her hopes, he just slipped the pen into the half-ghost's other hand.

"Write down a sentence." Dan pointed to her right.

"What?" the teen gasped, confused.

"It's not important what it is, just write down a sentence," he repeated, seriously.

Dani furrowed at the odd request, then stared at him. "Why?"

"Because I am curious if you are ambidextrous too or not."

"I'm the what?" yeah, well, using such words like that, she must have thought it was something like a curse. Luckily, it was one from his fascinating vocabulary in his mind within the many 'fancy' words that Dan could understand.

"Both-handed." he translated, tapping his fingertip on the paper between them, that originally he had got to explain the tricky ones in Dani's homework. "Now, write down a sentence."

"I can't see how is this important right now."

"It's not important, I am just simply curious." Dan cleared, but evolved it to the weird look on her. "Danny is right-handed, but you are clearly using your left hand for writing. I am curious if you are preferring that over the right, able to do everything with both or you are just basically left-handed." to the confused face, Dan raised up a brow. "What? I just noticed this now..."

"Not that." Dani shook her head, attempting to write something down, but awfully failed. It ended up as a scratchy childish bunch of crossed lines, hardly representing any known letter or word. "See?"

"Well, that's interesting…" Dan frowned thoughtfully. "Did he uh- teach you or you know… you were uh- like this always?" he took the question, but then bit his lips, grimacing as he realised what he asked. "I mean... I- sorry. I know you don't like to talk about it." and indeed, glimpsing at the girl, he detected her struggling look. "Forget I asked, okay?" he waved in the air, like that could make his inappropriate inquiry never happened.

For a moment, there was just silence and Dan took a look at the troublesome example in the opened book, to return back to figuring out the homework. Then as he tried to catch the eye-contact, Dan identified as the youngster was somewhere else. He gently poked her, to get her attention, the half-ghost slowly blinked, turning to him with seriously deepened crossed eyebrows.

"I am Danny's clone and you are Danny. How is it that I am left-handed and you are both-handed, while he is not?" the girl asked, undoubtedly puzzled over this unaccountable difference.

"Well, it's..." Dan started, but then shut his mouth, well-aware of the possible reason since he spotted her writing method.

"You know why, right?" the teen saw through his too quick movement, staring at him.

Dan scratched his forehead, trying to come-up with a believable lie all of a sudden, but then the easiest explanation came to his mind. "I think, in your case, it might be connected to your biology," well, that wasn't entirely a lie... "I mean, you are a girl, Danny is not, so by that, it is highly probable you ended up entirely altered in other aspects too."

The ghost girl was thinking, narrowing her eyes, as she was trying to put it together reasonably, but then nodded, accepting it. "And what about you? And please don't tell me it belongs under the second rule. It's really a small thing and it couldn't be connected to anything in your past, you don't talk about." Dan opened his mouth, but then closed it.

"Okay," he came across a moment later, "you really want to know it?"

"Yes," Dani nodded, sighing as she rolled her eyes.

"It's because of Vlad." Dan twisted his resting on the table fingers, as he recalled the memories about it. "He was left-handed, but was forced to use the right instead as a child, so you could say, he kind of taught me for both." well, in a certain view, that was true… except 'taught' was like learning something like passing that knowledge out in a short-of embedded inheriting.

"It could be learned?" Dani's interested voice slipped in his mind, bringing him back to the present and not wandering off in how long those 'forcing' had felt.

"With very hard work," Dan let out, with a half-smile, nudging the half-ghost sitting next to him, "you are unique enough with being left-handed, Dani. Besides, in fights it's unexpected. If I teach you to be good with both, you'd prefer to use with time the right one and you might lose your current advantage."

"Oh." the teen gasped, slightly disappointed by the refused teaching, but then without any further word, she came to see the benefit in that, realising it was better this way - especially if he said so too.

"Indeed," Dan agreed and put back the pen into the basic state. "Now, what was your question with the equation?" he asked, paying attention to the task that needed to be solved. But in mind, he was somewhere else, only numbly writing down the halfa the deduction for the solution - exceptionally with his right, otherwise, he would have covered the textbook with the necessary variables.

But on the other hand, there started to appear some very strange oddities about the girl, on what Dan just couldn't pass over, recognising, in fact, he didn't know anything about the teen. Dani was right, she was supposed to be Danny's clone, knowing well Vlad and his enthusiasm over aimed things, he was sure it was something more about an unexpected or missed glitch in her creation. But, unfortunately, the young half-ghost wasn't willing to talk about it, so then, Dan had no other choice to figure out these more and more disquieting alterings, but to go after it on his own.
