While the team is underground, Gretchen attempts to double-cross them. She meets with General Krantz under the guise of returning to The Company, but her ultimate plan is to kill him and take Scylla for herself. However, the General reveals he knows she is lying and has her captured.

Michael’s condition continues to deteriorate. He experiences severe symptoms from his brain tumor, including bleeding and temporary loss of focus, which nearly compromises the mission during a critical moment while balancing over the sensor-laden floor.

The title "Quiet Riot" refers to the team's need to infiltrate a high-security vault without making a single sound. The vault is equipped with noise-sensitive microphones and floor sensors capable of detecting the slightest vibration.
