With Dante taken down, the Italian Government believes that the Social Welfare Agency has seen too much and is now a threat. With new orders from the Government, troops move in on the SWA at the Turin Power Plant, secureing Dante. Meanwhile, another detachment prepares to raid the SWA headquarters, and demands that the SWA staffers stand down. Claes decides to step in as well and goes out to try talk to the troops surrounding them. Meanwhile, Pope John XXIV addresses a crowd at Saint Peter's Square asking for the violence to stop and the recovery operation begins at New Trino. With Padania defeated, it is time for the Social Welfare Agency to come to an end.
