During the mid-1980s her father met and married an unnamed woman with whom he had a daughter Eileen, both of whom hated his IRA activities. In the 1990s, Brennan was sent by the IRA command to London to conduct operations there, compelling him to take his family with him. Brennan continued to work on bombs 24/7 at the expense of his family. One fateful day, Brennan was tasked with taking out a British politician and set about building a bomb for the mission. While he was doing so, he got into a fierce argument with his wife and due to his being distracted, he accidentally mixed the wrong chemicals together, setting off an imminent explosion. Brennan yelled for Eileen to get out of their apartment immediately; Brennan and his daughter survived but Brennan's wife was killed, forcing Brennan to abandon Eileen, his mission and the IRA.
