The Organization does not belong to me, obviously. Demyx/Larxene, of all things to write for my first overt pairing. Not really worksafe, though I'm not sure it merits this rating or not since there's nothing explicit. Oh, well.
Had anyone suggested the possibility to the other members of the Organization, the kindest reaction they could have expected would be outright mocking. As it was, not even Demyx or Larxene spoke about it, even to each other.
They didn't talk about how, after weeks of watching, Demyx sprang an ambush on the then-youngest member. It involved a number of water clones, and her pinned against one of the castle's white walls, too soaked to electrocute him if she'd been so inclined.
(They definitely didn't talk about how, after hours of listening to his complaints follow her around, she'd relented and produced a potion for the scratches he had after that stunt.)
Thrillseeking, maybe, considering their opposing elements. All it would take was one slip of control while Larxene had him flat on his back, or Demyx cornered her in the bathtub – but the one time she did give him a shock, he simply laughed and bit her again.
They never spoke very much when they were alone together, letting their bodies do the speaking instead. It wasn't, couldn't be, anything more than the physical, thanks to their complete lack of hearts. She still bristled possessively when II gave the musician, to her mind, overly-friendly encouragement for successful missions. Days later, Marluxia ranted in the break room about his fountain, which had begun flooding almost immediately after he'd suggested that she join him for the night, instead of whatever 'poor soul' she'd been taking to her bed.
Demyx didn't say anything after Larxene broke the silence one night to tell him that she was going to Castle Oblivion. She didn't expect him to. After all, they didn't talk about the outside when they were together.
He didn't expect her to not come back. He didn't talk about that, either.
