Agent Kallus laid a trap in the Old Republic Senate Building in an attempt to capture the Ghost Crew. Using the fake rebel Senator Gall Trayvis, the Empire intended to lure the rebels into the Senate Building. However, the rebels managed to elude the trap due to early warning from the Imperial cadet Zare Leonis and the precautions taken by the rebels. During a pursuit in the sewers, Trayvis attempted to trap the rebels but was knocked to the ground by Hera Syndulla, who quickly realized that he was a traitor. Trayvis was left in the sewers while the rebels escaped from Imperial forces.
