A horribly convoluted plot might convince the world that Ollie is not the Arrow, but makes us wonder how the Arrow can ever return. Meanwhile, the Arrow turns to the Atom to help with a metahuman villain– one who apparently wasn’t created by the Central City particle accelerator. Cisco Ramon makes an appearance, and Ra’s Al Ghul makes a deadly move.
The episode asks one lingering question (how do the metahumans feed and so forth in the pipeline?) and poses another: is Arrow broken?
Neither receives an answer this week.
