Rion was to find Lilia-- with the memories he carried from the Original- and bring her to Mother, so that I could kill her.
It is a little complicated: Lilia carried the virus, and Rion carries the activation program- the only way to kill Mother. The original Rion carried the chip, but for some reason she couldn't extract his memories to find Lilia without destroying the chip. The original Rion died in the hospital due to trauma, they sent his brain downstairs, and remade Rion to be a Galerian. To be Mother's tool. Once his job was finished, I was to kill him. That activation program is very dangerous to have hanging around.
But Mother did not foresee that he would become so attached to Lilia. None of my siblings could wrench her from him.
