The Admiralty has opened an inquiry into the Olympic accident, and Pirrie, Andrews, Morgan and Mark are invited to London. Mark is pleased to see his old friend Kitty, who has become a star. At the inquiry, the First Lord of the Admiralty, Winston Churchill, suggests that the yard could serve several ends in case of military escalation. Joanna Yaeger, Mark's old friend from New York, and Morgan's protégée, is forced into a very dangerous position: a spy. With her unparalleled access she can prove to be extremely useful to the Austro Hungarian and German causes. Back in Belfast, Mark faces a new crisis. Andrea, Sofia's old fiancée, has seen her with him and has told Pietro. Sofia is forced to choose. Sofia stays Mark. Finally he agrees to follow Sofia: they will move to London, together. He will leave Harland & Wolff and all hopes to ever find his own daughter. In a breathtaking ceremony, the Titanic is finally launched.
