'Arrow' Season 5 Episode 16 Air Date & Spoilers: Oliver Queen Discovers Adrian Chase Prometheus Secret In 'Checkmate'

The truth about Prometheus has finally been revealed in "Arrow" Season 5 and there is little doubt that Adrian Chase will continue terrorizing Oliver Queen. Is there any chance that Team Arrow will manage to save Susan Williams in "Checkmate"? Will Oliver finally learn that a man he trusts has been trying to ruin his life all along in "Arrow" Season 5 Episode 16?

In "Fighting Fire With Fire", Prometheus finally removed his mask and revealed to the viewers that he has been Adrian Chase all along. However, Oliver Queen and Team Arrow are still unaware of the villain's true identity. Could things change now that Prometheus has kidnapped Oliver's ex Susan Williams? There are speculations that "Arrow" Season 5 Episode 16 will have Oliver discovering the truth while dealing with Susan's distrust over her abduction.

The synopsis for "Checkmate" confirms that Oliver Queen will learn more about the villain (via ComicBookMovie). Does this mean Oliver will finally discover Adrian Chase is actually Prometheus? The YouTube trailer for "Arrow" Season 5 Episode 16 also shows that Oliver will try to save Susan Williams. However, there is a possibility that Susan could end up making things difficult for Oliver before the season finale.

Josh Segarra recently spoke to IGN about playing Adrian Chase and not knowing he would turn out to be Prometheus. The actor teased that the villain's abduction of Susan Williams could be "a very, very important piece" of the show's current storyline. Segarra revealed that Oliver Queen's ex might "feel betrayed", a major development that Adrian could use after "Arrow" Season 5 Episode 16.

Can Oliver Queen save Susan Williams from Prometheus in "Checkmate"? Will Team Arrow finally realize that Adrian Chase is the villain they have been chasing all season? "Arrow" Season 5 Episode 16 will air on The CW on March 15.
