"My sister Arkady. Got that same sort of..." He waved a hand, a circular, searching movement, "Like she's not all there and right where she's supposed to be at the same time sort of presence." He shook his head, "Not sure if that makes sense. That sort of feeling that she might know everything, but doesn't remember it all at once." He shrugged then, not really sure how much to reveal about his own powers, which meant that he couldn't reveal a lot about Arkady's, since they were similar, "She almost died once, when we were younger, the rest of us figure that's what triggered it, sometimes she says she left her memory in the future and she's always trying to catch up to it." A small, fond smile, shaking his head again, "And sometimes she 'remembers' things that haven't happened yet. Which is how she figures her memory's up ahead of her somewhere."
There was a huff of a laugh then, shaking his head once more, "Makes her sound like an absolute nutter, makes me sound like one for believing it. But she was always the sharpest of us, asking the questions the rest of us had ignored for being too obvious, or hadn't got to yet on account of trying to sort out smaller things first. She always got right to the heart of it."
