Arrow season 3, episode 20, “The Fallen,” airs tonight, as Oliver brings Thea to Nanda Parbat.

Previously on ‘Arrow’

After being arrested for being the Arrow, Roy was confronted by Captain Lance, who wanted to save him, but Roy felt he was making amends for killing a cop by being locked away. However, a guard shanked Roy, leaving him to bleed out. This turned out to be a ploy designed by Roy, Felicity, and Diggle to fake Roy’s death and clear Oliver of his charges. Roy eventually left Starling City for a fresh start.

Meanwhile, Team Arrow was forced to team up with Ray when a metahuman attacked Starling. Though Ray was initially defeated, Oliver coached him through defeating Deathbolt on their second confrontation. After bringing Deathbolt to S.T.A.R. Labs to be locked up, however, The Flash‘s Cisco revealed that Deathbolt had not been in Central City when the particle accelerator malfunctioned, leaving the origin of his powers a mystery.

The episode closed with Ra’s al Ghul confronting Thea in her apartment and stabbing her to force Oliver to become the next Demon’s Head.
