Ch. 523'Insecticide'
William gathered his officers to plan the extermination of the Arachnid Swarm and learned that more than 633 stellar systems were already known to be within its quarantine zones. Rebecca and Halsey revealed they had developed a virus called Insecticide to eliminate the Swarm, leaving William and his officers to consider their proposed solution.
- William accepted Constantine's offer, then headed to the bridge to discuss the extermination plan with his officers.
- Serena reported that Federation intelligence had identified at least thirty planets containing Arachnid brain bugs and 633 known systems within the Swarm's quarantine zones.
- Rebecca reassured William and revealed that she and Halsey had uploaded a file called Insecticide to the carrier's network.
- Halsey explained that she, Rebecca, and 049 had developed Insecticide using the T-Virus, Blacklight Virus, a brain bug specimen, and Elizabeth Green.
- Rebecca said Insecticide was contagious, had a long incubation period and high mortality rate, and could stop the Arachnids from reproducing.
