Author's Note: Yazoo POV.
Yazoo hears their mother's voice. Sometimes he wishes he didn't, but most of the time he doesn't mind. If it hadn't been for their mother's voice, he would never have known that Kadaj and Loz were his brothers. If it wasn't for their mother's voice, Yazoo would be alone and would never have known the difference except by the empty places at his side.
The three of them had been designed as a unit from the start. Loz had the brute strength, Kadaj the personality driving them to succeed, and Yazoo himself had been created as nothing but the embodiment of cool, measured calculation. They were the different parts that made up the whole of something extremely dangerous, but Yazoo knew from listening to the scientists when they thought he couldn't hear, that the whole had once been one being, instead of three. Yazoo had at one time been curious about the person that they together had once been, but even if Loz and Kadaj were his brothers, they were not the same person, and Yazoo didn't want them to be. Even if that is what their mother wishes for, if that is why she makes Kadaj scream until his voice is hoarse and Loz cry silently in his sleep, Yazoo will not allow that to happen. He may not hate mother as he knows Loz does, no matter how much his elder brother tries to hide it, but Yazoo loves his brothers far more than he cares about Jenovah.
Yazoo hears their mother's voice, but not as clearly as Loz and Kadaj. To him, Jenovah is just a presence, a bodiless specter that most of the time he ignores. It is only when Kadaj starts to scream that Yazoo allows himself to listen, and then it is easy to find the words that allow his younger brother to cut off the voice shrieking in his mind. To him, the words are meaningless, but they mean something to Kadaj, and when Kadaj is in such pain that he can't see his brothers through his haze of madness no matter how hard he tries, what matters to Kadaj is all Yazoo cares about.
Now is such a time. Yazoo looks down at his brothers, Kadaj struggling against something only he can see and a barking, painful laugh making his body shake, Loz holding onto their younger brother as tightly as he can while sending Yazoo a wordless plea to say the words that he's never been able to find.
It is only for his brothers that Yazoo will do this thing, to listen to their mother's voice when the very sound of it in his mind makes him shudder from the strangeness. He listens, and what he hears means nothing. But as always, he says it anyway. "Don't worry, Kadaj. The Reunion will happen soon, and then mother will come back."
Yazoo watches at his younger brother relaxes, the green in his eyes retreating enough to let Kadaj to return to himself, to them. He watches as Kadaj finally drifts off to sleep.
As soon as he is sure that Kadaj is truly asleep, Loz turns to Yazoo. "The words you say. What do they mean?"
Yazoo gives a shake of his head. To him, the words are meaningless and always have been. But Yazoo had made a promise to himself the first time he had laid eyes upon his brothers and known what they were to him. As long as mother makes Kadaj scream until his voice is hoarse and Loz cry silently in his sleep, Yazoo will say anything that allows his brothers to come back to him, no matter the taste the lies leave behind.
