“Since I’ll be the carrier... The child may become tempered in the womb,” he didn’t know if Prometheus knew this already. It was likely that he didn’t. It’s not like he went out all that much. All the children stayed close to Zodiark’s protection... and of course he tempered them.

“I’m not entirely sure that Zodiark can control it either,” Hades said, expression drawn with his arms folded. “So... I suppose you should cope with that possibility sooner than later.”

And of course, were someone to ask that if Zodiark changed him... he was never entirely be sure. Of course he knew that they all became tempered, but that was by design, not flaw. What good would a god be that fell out of favor or acted against its peoples’ wishes and best interest?

“Even if they aren’t...” it’s a matter of time, he didn’t say.
