Arrow Sezonul 1 Episodul 22 - Darkness on the Edge of Town
The time is fast approaching for the Undertaking to occur and Malcolm Merlyn begins to tidy up the loose ends, beginning with the scientists at UNIDAC. Oliver and Digg trick Moira into telling just what the Undertaking is about. Oliver realizes that even if he manages to eliminate everyone on his father’s list he has only, in his own words, eliminated the symptoms and not the disease. Felicity locates the UNIDAC device – sort of. Thea and Roy’s relationship comes to head when they are unable to locate the vigilante.
