Arrow Talk Podcast #89 - S 4 Ep 20 GENESIS

Darhk returns to H.I.V.E. and kills the remaining board members before renewing his plans for "Genesis". Oliver and Felicity meet an immortal shaman, Fortuna, who educates Oliver about dark magic. Fortuna explains that Darhk's idol channels darkness and death, feeding him more power, but there is an opposing force that channels light and hope. After a mystical ritual, Fortuna tells Oliver that the darkness inside him is too strong to channel the light. In Star City, Diggle locates Andy, but is captured after a brief shootout. Andy puts a tracking device on him, then allows Diggle to escape so that Darhk and his team can go after Diggle, Lyla, their daughter, and steal the "Rubicon" to the world's nuclear weapons. Oliver manages to stop Darhk by channeling the power of light, nullifying Darhk's powers and forcing him to retreat. Diggle and Andy battle again, with Diggle ultimately killing his brother. Thea is taken by H.I.V.E. to a secret underground city. The team realizes that Darhk plans to detonate nuclear weapons and build a new world over the ashes.
