- Title: Arrow – Checkmate
- wiki: link
In “Checkmate” Oliver (Stephen Amell) not only discovers the identity of Prometheus but the episode also reveals a far more powerful enemy behind the man who has been torturing the Green Arrow for months. Unable to go head-on against Adrian Chase (Josh Segarra), Oliver’s team searches for the kidnapped Susan Williams (Carly Pope) which will also lead Felicity (Emily Bett Rickards) further down the rabbit hole in her dealings with the hacker collective Helix.
With Talia al Ghul (Lexa Doig) working with Prometheus, Oliver’s job to take down the madman just got that much harder. Captured at the end of the episode, his real battle between the pair has just begun. The question for Felicity is just how far will she go to try and find Oliver Queen, and will she be able to live with and come back from the decisions she is about to make?
