Her silence -- no, her absence of lip movement or even conspiratory blinks -- spoke volumes. Lukas stiffened with her turn, the toe of his boot sweeping forward in the sudden pursuit that he hadn't even considered or explained to himself. Not to worry, it was only one step, and then he stilled with her continued retreat.
The truth was simmering between them, it offered ghost glimpses of haunted steam and memory. Why was it the shift of her spine that he remembered or imagined? The way she turned away with a cold, unconcerned, lookout eye.
Lukas didn't go after her, he merely watched the path that she took and registered the location. First floor, ground zero. It was something to keep in mind.
