During her pregnancy, Elle didn't tell Robert about the children, and she was killed after childbirth because of a precognition that she'd lose control of her ability and kill the twins. After this, both children were originally raised by Primatech as agents, under the care of their grandfather, and 22 years later they travelled back to the present day, to change things for the greater good. However, time was changed, resulting in their father learning of their existence, and forcibly taking them from the Company. Elle was also revived. The pair decided to raise the children together, and eventually also resumed their relationship. They hid in Russia during the persecution of evolved humans, but are now all living in New York.
