Oliver tests the Vigilante Registration Act by outing himself at a press conference, praised by the general in charge. As feared, he's tortured in a secret prison to turn on his superhero friends. Tess helps work out the design from Luthor plans for an underwater top-security facility, build in sixfold. Aquaman 'A.C.' Arthur Curry and his new wife Mera discover and penetrate the one Oliver is held in, but the general rather starts auto-destruct. Clark remains cautious and flashes to the rescue but has to deal with a specific counter-measure.

As the VRA threat intensifies, Clark takes initiative by closing down watchtower and declaring the League go officially underground, but will this be enough to stop Lt.Trotter and Slade Wilson aka Deathstroke from exposing them? Tensions rise in this mid-season finale.

Clark, Oliver, Lois and Dinah are back home after long VRA captivity, with confused memories and robbed of all superhero-powers. They believe they have been tortured in an experimental lab by none other than Chloe, hence fear she switched sides. Then she, or rather her avatar, appears in dreams to each of them, claiming they only lost their powers in a virtual illusion, which can nevertheless kill them for real. She calls upon them to trust her, break the virtual spell by believing it fake and thus escape back into reality, with Rick Flag's team. Oliver does so quickly, and is reunited with his true love. Clark wants to, but finds it extremely hard, until Lois joins in.
