Titanic Blood and Steel Danager Looms Episode 4

Walter's death has changed the whole picture. Malcontent breeds amongst workers, especially at the shipyard. Larkin has been forced to leave the city. Andrea, to Sofia's embarrassment, is staying at her house. Emily returns to work, but cannot emotionally function leading to her job being at risk. Lord Pirrie is shocked by the unrest and fights with his former friend Henry Carlton – Kitty's father – whom he holds responsible. He seeks an understanding with Michael McCann, one of the leaders of the workers' movement. They are both intelligent and moral men and Lord Pirrie offers to work with Michael any way he can to help the workers. Andrea recovers from his head wound during the riot at the Silvestri household with Sofia attending to him, in which his continuing boyish love to her turns into obsession and anger as she still will not accept his love to her. Meanwhile, Mark keeps his mind on his job and finally identifies the problem with the steel: impurities. But the steel complies with regulations. Eventually Thomas Andrews will see his point, and a new relationship will form. But work is not Mark's only occupation: he finally kisses Sofia. Mark also rejects Kitty when she tries to come onto him again. At the end, when Mark goes to the hotel to visit his father, he is assaulted by Bernard Doyle who accuses Mark of having abandoned his fiancée, Bernard's daughter Siobhan, who died in childbirth years ago.
