After Roy was unresponsive to his training methods, the Arrow took Roy out to stop a newly-escaped Bronze Tiger from stealing Malcolm Merlyn’s prototype earthquake machine. But Roy’s uncontrolled temper allowed Bronze Tiger to escape, putting the entire city in danger.

To reach Roy in his mirakuru rage, Oliver revealed his identity and invoked his sister’s name. Together they destroyed the prototype, and Oliver introduced Roy to Felicity and Diggle, making him an official member of Team Arrow.

Meanwhile, Walter convinced Moira to run for mayor against Sebastian Blood, and Laurel continued spiraling. In the wake of an overdose after learning she was being disbarred, Laurel found herself face-to-face with Sara.
