Darius was actually smiling about this! Lux idly backed away, surprised and angered by this change in tone. Either he found her amusing, or he enjoyed this kind brutality. Neither mindset was one that Lux supported. She decided that it was time to give him something to once again frown about.
To Darius, suddenly, Lux simply vanished. A moment later, several feet beside where Lux was, a mirror image of Lux appeared, posing in just the same way. A moment later, it too disappeared, replaced immediately with two halves of Lux - one to Darius's left and one to his right. These halves were divided down the middle, and the 'cut' simply blurred into nothing.
"I own hide and seek, Darius." Lux's halves said in unison, her tone oddly neutral and her expression calm. "Come at me, bro."
These halves too disappeared, and were replaced by a normal Lux, standing to Darius's side, a dozen feet from him.
