((So you may feel like the thing Sekhet reveals is a bit of a let-down... sorry about that in advance!))
Perhaps it was naive of Sekhet to even believe Nexus's story. But... it made sense. To an extent. He had powers that were... strange. He had a strange eye. He certainly didn't seem to fit the mold of every other surface dweller she had met. And there seemed to be truth to his words... a weight that she could detect. She had no reason to believe that it wasn't the truth anyways. And if so, it was a grand lie then. A lie that she would prefer to believe rather than the truth. The truth was painful, and it was ugly.
It was strange to admit her story to a stranger. She felt... exposed. Baring something that she had let fester to her heart. Her weakness. The story of why she was here. It wasn't a good feeling-- it wasn't like she had shrugged off this burden by telling it. It was more like the burden was more pertinent. The exile, more explicit. She was stuck confessing her sins to a stranger. She was truly an outcast, and nothing in this heaven and earth was going to change that. This was only making that fact more prevalent, something that sank below her skin and would tug at her until she tore herself apart.
When he mentioned the voice, Sekhet just peered at him. "Ignore it," was her simple solution. "She can't have that much control over you..." That part still didn't make any sense to her. But there were many parts of this entire situation that made no sense to her. But if he didn't want to be controlled.. wasn't even knowing that there was a voice meant that he was failing at that task? Or fate is simply a cruel bitch that will beat you until you're broken.
The conversation took a downturn. All of the images that haunted her in her sleep.. it was becoming her waking nightmare. She couldn't fight them back now; the lifeless eyes, the curling fumes of blood in the water... it was there. And it was real. She couldn't take it back. And every word he said... it only made her angrier. She struggled with her fate, fought it and let it take her over. Shackles that were tied to her wrists, ones that she couldn't break, letting them sink her. And it was her burden. Every word that Nexus told her was a lie, and her gaze only hardened into ice as he stood.
"I'm not telling you what I think all of it should be!" She snapped, her teeth even clicking. She couldn't fight the vile black thing inside of her. It was rising in her, choking her, making every word that Nexus said to her an attack. "I deserve this. I let them die! They were innocent! They were loved! It didn't matter what I did! They died, because of me!" Her voice was hoarse, as if every word clawed its way out of her throat, and her tongue only ignited them with the anger at herself.
She knew that his words weren't honest, and her eyes narrowed. "It was weak. There was a way to defeat them, had to be a way... and it didn't work! Whatever I should have done, I didn't do it!" But at what he said, the way he said it... he wanted to punish her. A snarl tore from her throat as she backed up a step, holding her trident protectively in front of her.
That thing inside of her was fighting, struggling... she snarled, and shoved her trident in the sand with violence, as if she was stabbing something, her eyes wide.
"You weren't there!" She screamed at him, as if he was the personification of everything that she had lost. "You didn't see the light leave his eyes! You weren't holding the prince's body as he looked up at you, you, as if you were the only god damn thing that he ever wanted! You didn't hold him! You didn't feel his heart beat in your hands!"
She didn't even realize that her cheeks were burning, that her chest was heaving, that she was leaning into her trident until the tines disappeared into the sand, that her voice was choked.
"You didn't hope, pray that his sister would be alive! You didn't find her body, just as broken, just as battered and torn! You didn't feel like you failed him, the man you watched from afar, the man that only looked at you in death!"
She shuddered, and glared at him.
"He's the only one who should punish me. Not you. Never you."
