When dragons reach the level of power that Rey and Ray are at, their perspective of the world and reality itself shifts. Humans, who once looked as weak as bugs, are now the same as the inanimate dust.
When they first met Isdis, she looked to them like a shiny, sapphire pebble. An interesting product of the natural order, which they took an interest in and decided to play with for a while. A human's lifespan might be long for mortals, but for the Mana Drakainas, it was nothing more than spending a few moments admiring the beautiful pebble before marching on their way.
One day, an angry baby came along. He snatched the worthless yet arguably beautiful pebble from Rey and Ray's hand, claiming it as his wife. They weren't angry or bothered. They were old enough to understand that when a child sets his mind on something, you can't just snatch it from their hands.
