The death of Laurel Lance in Arrow Season 4 was a tragic event that sent shockwaves through the series, which can still be felt today. The loss of such a fan-favorite character, along with all her connected legacy from the Green Arrow comics, was an exceptionally dark moment for the CW superhero drama already known for its grim tone. But the introduction of Laurel’s Earth-2 doppelganger, known as Black Siren, gave Arrow a chance to create an entirely new version of the character, with a completely different story.
This Laurel had a harder edge, a more villainous attitude, and less of the complicated emotional baggage the Earth-1 version often struggled with. In many ways, Black Siren felt like a fresh start for a character the show often had no idea what to do with in the past. This iteration even came complete with an obvious initial narrative arc – redemption for her previous sins.
