In among all the trauma and heartbreak of Arrow‘s mid-Season 5 finale, ‘What We Leave Behind’ (Oliver being tricked into killing Billy, Evelyn making her betrayal public, Diggle getting recaptured), there was the surprising revelation that Laurel (Katie Cassidy) was somehow still alive, as evidence by her strolling into the Arrow cave.
SPOILERS AHEAD – or is she? From this, it looks like she’s actually the Earth-2 version of the character, aka Black Siren, seen in Season 2 of The Flash. If you don’t want to know anymore then it’s probably best that you don’t watch this.
Arrow: Season 5 will return to Sky1 later in 2017. For all the latest TV news, pick up the new issue of SciFiNow.
