Kyon didn't want to torture Valeera. He would never earn her trust back after that. However, he preferred the option where she hated him but lived rather than losing her forever. He would keep her alive whatever it takes!
Kyon returned to the interrogation room, took out a silver needle and went to the beautiful prisoner awaiting her death in silence.
«Valeera, you leave me no choice... Please, give me the frequency of your uncle's sound transmitter, or I will have to use a most severe method... It will hurt. It will hurt so much so that you will want to die...»
Valeera glanced at his surprisingly impassive, chalk-white face. A tiny, pointed needle gleamed in his hands. – «Will you stoop so low as to torture me?»
An oppressive silence filled the room. – {I was right…}
Kyon hesitated a moment, still hoping that his victim would change her mind, but then he slowly approached her and reluctantly but with a quick, deft movement thrust the needle infused with Synergy into her thigh.
(AC: The author doesn’t consider the girl in the image to be Valeera, but he finds her somewhat similar. If you feel the gloomy atmosphere, then the point is made: https://ibb.co/Tvf3Lvp )
