In episode three of the eighth series, following a hostage situation, Ros kills a terrorist before he can detonate a bomb. However, because Jo Portman (Miranda Raison) held on to the terrorist, the bullet passed through him and entered her chest, killing Jo as well. Ros has since been affected by it. In the fifth episode, she is contacted by Jack Colville, her recruiter into MI6. Later in the episode, Colville finds a way to hack into MI5's records through Ros' account to kill every officer responsible for the death of Mina, his love in Bosnia several years before. To stop Colville, Ros has her name planted as the one who ordered Mina's death. Jack pursues Ros and, as he is about to kill her, she reveals the truth. Realizing that it was not the agents, but the system that was wrong, he kills himself. In the series eight finale, a multinational shadow organisation, Nightingale, attempts to cause a nuclear war between India and Pakistan. To put a stop to it, Ros and Lucas attempt to rescue a paralysed Pakistani President Mudasser and Home Secretary Andrew Lawrence (Tobias Menzies) from a hotel rigged to explode. As Lucas rescues Mudasser, Ros struggles to pull Lawrence to safety, and is still inside as the hotel explodes, resulting in their deaths. In the first episode of the ninth series it is revealed that former Home Secretary Nicholas Blake ordered the bombing; in revenge, Harry travels to his home in Scotland and kills him by poisoning his whisky.
