In the alternate universe, a man frees his twin brother from a quarantined area; Olivia continues to be haunted by visions of Peter.

When a young woman meets a violent death after partying at Verdant, Detective Lance and his partner, Detective Hilton (guest star ROGER CROSS) inform Oliver and Tommy that she was on the drug Vertigo. Oliver immediately pays a visit to the mental institution where The Count (guest star SETH GABEL) is locked up, but finds he is in no condition to deal drugs. However, when The Count escapes and Starling City is flooded with even more Vertigo-related violence, Oliver and Diggle make it their mission to track him down. After Detective Lance uncovers incriminating evidence against him, Tommy goes to great lengths to clear his name, and the fallout from his actions leads Tommy down a new, unexpected path. In a flashback to the island, Oliver recalls the lessons he learned from Slade and Shado (guest star CELINA JADE).

Jor-El (guest star JULIAN SANDS) mysteriously arrives at the Kent farm searching for his son, Kal-El – but meets Chloe instead. Convinced the Blur is Jor-El, Zod enlists Tess's help in finding him, to force him to reveal the secret to his powers. When Clark realizes Jor-El is alive and on Earth, he races to find him before Zod does.
