The accident has created a terrible workload. Tensions between classes escalate. Pirrie and Michael finally manage to come to an understanding that appease the workers, but not magnate Charles Stokes. Unfortunately, Conor MacCann, Emily's younger brother, is driven towards more extremist acts after he gets fired. The Fenian movement, a Catholic terrorist group, takes Conor in. Mark suggests building a double hull for the Titanic. But Pirrie is unimpressed. It would mean wasting too much time. To try and forget his many concerns, Mark manages to take Sofia away for a romantic weekend. It is a time when love flourishes, giving both of them the illusion that everything will be fine. Henry Carlton has discovered Mark's real identity. Carlton is furious that his daughter, Kitty, has been in a relationship with a Catholic impostor. Kitty is disowned and she decides to leave Belfast. As soon as Mark comes back he is summoned and fired.

Losing his job is not Mark's only problem. Sofia knows his truth. Mark tells her everything. Even about Siobhan and the baby. She eventually forgives him. It is also time for Mark to reconcile with Sean. Mark's situation seems to get better still when JP. Morgan arrives. When told the reason why his chief metallurgist has been fired, Morgan has him immediately reinstated. Mark starts looking for a viable alternative to the double hull, an alternative he finds in higher bulkheads. General Elections are in sight. Home Rule for Ireland is at stake. The possibility that London putting a stop controlling the island is strongly opposed by the Protestant minority, which fears the power the Catholic majority would get. Emily persuades her brother Michael to stand for Parliament, and Pirrie helps and supports his main counterpart in the shipyard.

The high staked General Elections are drawing closer. The magnates have their own candidate, the Unionist extremist Albert Hatton. The fact that Pirrie does not support Hatton makes him an enemy of the ruling class. Michael is campaigning for Labour. His sister Emily helps him. But she gets arrested for giving out leaflets. This is a political measure, and Emily is only the scapegoat. On the ship front, Mark's proposition to erect higher bulkheads to defend Titanic is crushed by Ismay, the Chairman of White Star Lines, the company Titanic is being built for. When the elections occur, Albert Hatton wins a handsome majority. The third candidate, Michael, only gets a very small number of votes. Protestant and anti Home Rule extremists fume with rage and hatred, and Michael is assaulted, cruelly beaten and forced from Belfast. His brother Conor has become a terrorist and has taken lives.
