Oliver tracks down an accountant of the secret organization and steals his laptop. While decrypting it, Felicity uncovers a link to Walter—a money transfer was made to Dominic Alonzo, an underground casino owner who was hired to kidnap Walter. The pair infiltrate the casino; and Alonzo claims that Walter was killed. Oliver informs his family and Moira confronts Malcolm, who proves to her that Walter is still alive. Oliver, who was listening in, discovers that Malcolm is heading the secret organization, and uses Felicity to ascertain Walter's location. As the vigilante, Oliver frees Walter. Meanwhile, Laurel asks Tommy for the truth about why he left, and Tommy states that Oliver still loves her, a claim he confirms. He asks Diggle to help him stop the "Undertaking". In a flashback, Robert is shown disagreeing with Malcolm's proposed "Undertaking", which would involve leveling the Glades with a machine, which will be built in five years, and killing thousands of people in order to rebuild the area. As a result, Malcolm has a bomb planted on the Queens' yacht just before Robert boards it to head to China for his plan to stop the former.
