Sure, she was his slave, but her job was to simply be that. She wasn't loyal to him; she wasn't allowed to betray him.
However, there was a sense of warmth in her heart when she realized how lucky she was. She had become a slave, yet by becoming so, she gained Silas' protection and became one of the only people he could fully trust. And since that was the case, it also meant that she was one of the only people he wouldn't hurt her, even if he killed everyone around her.
She was at his mercy, but that was much better than the alternative that many others would face if Silas even suspected them of being an enemy.
However, she was not the only one with her worried about Silas' sudden change in his stance of not hiding his power anymore.
Alex, who was watching from the side, couldn't help but feel a little fear toward Silas after seeing him so easily kill someone who was supposed to be his rival in the election.
