Ch. 503Preparing to Capture the Brain Bug

William and his forces deployed to capture the brain bug known as “Milky White Fat” alive. After arriving at the wormhole, the Ghost Agents entered first, followed by Gene, Rysgaard, Tiz, and the Roughneck elites as bait.

  • William briefed the Primarchs, Ghost Agents, and Tough Bones Company on the plan to lure Milky White Fat out of the wormhole and capture it.
  • The convoy and escort formation reached the wormhole entrance in a barren valley, where the MS units, Vultures, Helljumpers, Frenzied Sharks, and Crucio Tanks took up positions.

William and his team interrogated Federation generals Clay and Owen about the truth behind Buenos Aires, but neither knew the full story. William then addressed Federation citizens and soldiers through Serena’s livestream, demanding that the Federation publicly clarify the facts.

  • William’s team escorted Clay and Owen from the prisoner camp to Umbrella’s Supply Base while the Arachnid Swarm attacked both facilities.
  • Nova psychically compelled Clay to explain that he lacked access to information about Buenos Aires and that Hossent Wolf had been removed as commander after questioning the meteorite attack.

Ch. 510Father Who Betrayed His Son

Carl admitted that the Federation had destroyed his home and agreed to testify against its leaders during Umbrella’s broadcast interrogation of the brain bug. As the group headed to the laboratory, old romantic tensions resurfaced, while William quietly encouraged the rivalry between Ivan, Siya, and Nova.
