Julie shows Lucy her future brothers and sisters.
Hybrids were infiltrating the planet, leaving the government feeling vulnerable and powerless. If they were going to prevent an alien takeover, officials knew they would need more Humanichs like Lucy to carry out attacks. Without having the time to create individualized personalities for each Humanich, Julie chose to program the 100 combat-ready machines with Lucy's exact baseline.
But, before she powered them up, Julie wanted to show Lucy what the future of Humanichs looked like. While Lucy could have been concerned about sharing the same memories with other soldiers, she ultimately took the move as a compliment to her strength, intelligence, and ability. Lucy's family was growing, and she already knew everything about them.
