Chloe Collins and Alexander Foster didn't need to say much, they didn't even go to the company, only staying at home.
Many people were concerned about Tristan Collins' condition after he fought off the virus, only to suddenly learn that what he fought off wasn't the virus at all but the cure.
In an interview, Chloe also revealed that before the great chaos, she had people secretly infiltrate the robot company in Valleys and tamper with their programming.
At the same time, she collaborated with the president of the Whites, Milton White, to switch the Valleys' virus with the cure.
That's why, on the day of the great battle, the robots took the initiative to inject mutated human armies with the vaccine.
The Foster Group vaccine and cure were thus fully embraced; the mutated people hiding in various places voluntarily lined up to get vaccinated without any thoughts of rebellion.
