SPOILER WARNING: This article contains major spoilers for "Collision Course," the latest episode of Arrow.
Arrow's Black Siren just made a game-changing decision. At the end of "Collision Course," the latest episode, she managed to escape both Teams Arrow. However, due to her gunshot wound, she didn't make it very far and approached the first person she came across. Sobbing, she told him that she had been kidnapped for two years, implying that she was actually Earth-1's late Laurel Lance.
Over the course of the episode, Quentin Lance tried to convince Black Siren that she still had some good left in her. She dodged his attempts at almost every turn, but was too injured from her injuries to escape. Soon, the original Team Arrow -- Oliver, John Diggle and Felicity -- discovered that she had stolen the money Cayden James embezzled from Star City. When they demanded to know where it was, she bargained her freedom for the information; she would only give up the money when she was out of the country.
As Team Arrow attempted to arrange this, New Team Arrow -- Dinah Drake, Curtis Holt and Rene Ramirez -- showed up. Both vigilante teams came to blows over Laurel, who fled on foot into the woods. Though the teams were forced to stop fighting when Rene collapsed from his injuries, it was too late: Laurel was gone and her trail had gone cold.
However, like Oliver predicted, Laurel didn't make it very far. She stumbled across a man standing outside his van, who became concerned at the sight of her. She appeared to him disoriented, though she was anything but that. She begged him for help and told him that she was held captive for two years. Seeing as Earth-1's Laurel Lance died roughly two years ago, it's clear that she is pretending to be her Earth-1 doppelganger.
So far as the rest of the world knows, Laurel is dead, but it probably won't stay that way for much longer. Since the general public is unaware that the multiverse exists, Black Siren's story about being kidnapped will be easily believed. With this story, Laurel will likely put herself into a national spotlight as the darling daughter of Star City who -- long thought dead -- endured years of captivity. This poses a real problem for both Teams Arrow, who know the truth about her evil, manipulative ways. She will likely use the stories that Quentin told her to perfect the illusion, while leveraging her knowledge of the vigilantes' true identities.
Starring Stephen Amell as the Emerald Archer, Arrow airs Thursdays at 9pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, Willa Holland and more.
