This is a fairly old drabble, but I think it deserves a place on ff.n It was written as a challenge for a meme on lj, and take place during the first GitS: SAC, in the second to last episode (which had me crying and squeaking in turns)

She couldn't deny her fear. It was a natural instinct to sense the predator and fear it. But she barely felt it – it was a prickle at the back of her mind, telling her to be wary. Her ghost, whispering to her of danger and men in black suits, out for her life.
The lack of fear was no surprise – she felt most emotions this way, prickles and brushes at the back of her mind which she could examine from far away, and then decide what action to take. It was what made her such a calm leader; she never showed anything on her exterior - never felt anything on her exterior.
Thus it was a surprise that when skin met skin as Batou pushed her from the window she needed to pause. Her skin was…tingling. Or at least, her cyber brain was registering the feeling of her skin tingling – but that was completely ludicrous. She had no nerves in her skin any more, fiber optic or real.
She half-closed her eyes and heard it, her ghost, whispering. Whispering, singing softly. Then something else joined it; whispering back, singing in harmony that was a melody all its own. She didn't have to guess, she knew what, and who, it was.
His ghost. Him. The small part of him that was still human, whatever that was these days. Their ghosts were aquatinted already, from working for so long together, but now there was more. They touched, clung to each other, shivered and writhed. She caught her breath, and the moment passed.
But she still felt the alien tingle on her skin – and she knew that he did too.
