Earlier this season when Felicity went onto the dark web again, she was contacted by a young female hacktivist (played by Hannibal's Kacey Rohl) who wanted to meet her idol. During their meeting, the bubbly young woman explained that she's a member of Helix (a supervillain group) and handed Felicity a jump drive containing stolen data from the NSA. Since then, Felicity has used the jump drive to exonerate Diggle, blackmail a Russian telecom executive, and quickly track down the villain(s) of the week.
Of course, nothing comes for free, and Helix will ask Felicity for a favor.
OLIVER SEEKS THE TRUTH — Oliver (Stephen Amell) gets closer to the truth about Prometheus. Meanwhile, Helix refuses to continue helping Felicity (Emily Bett Rickards) until she does a favor for them.
Ken Shane directed the episode written by Beth Schwartz & Sarah Tarkoff.
