Complete story — includes the ending
Slade tries to persuade Joe to leave with him, but he refuses, claiming that he saw his father kill the Chinese agent before he was influenced by Mirakuru. Slade tries to explain that it was a paid hit, but Joe refuses to forgive him, stating that learning who his father truly was led him down this path. Joe and Slade end up fighting until Oliver steps in, after which Joe escapes but not before revealing the existence of his brother, Grant. Slade tells Oliver he will continue to try and find both of his sons, but advises Oliver that he go back to his, not wanting Oliver to make the same mistakes he made. Meanwhile, Team Arrow fights against a new criminal group, led by Ricardo Diaz, who attempt to steal a valuable technology. The team eventually finds out about John's tremors, leading John to apologize to everyone. Curtis offers to help John the same way he helped Felicity when she was injured. John asks to have the night to think it over. Slade's flashbacks focus on his rise as Deathstroke and his relationship with his adolescent son Joe in ASIS.
