Later in the series, a group of terrorists storm a meeting of industrial billionaires and begin a series of ‘trials’, broadcast via an internet stream that bring to light the white collar crimes of those in question. After the first of the hostages is executed, both the US and UK governments agree to an aerial bombardment as a counter-strike. With Ros also taken hostage and out of radio contact, Harry instructs Jo to approach the hostage takers and negotiate. Her attempts prove initially successful, but the group’s leader attempts to detonate an explosive. A struggle ensues, and Jo is caught in an awkward hold with the terrorist. It quickly dawns on Jo that the only way to bring the situation to a close is an act of self-sacrifice, and she silently nods for a now armed Ros to take the shot; killing the terrorist, but sacrificing herself in the process.
