Considering Arrow season five’s midseason finale cliffhanger – Laurel apparently returning from the dead and cheerily turning up in the Arrow Cave saying, “Hi, Ollie!” – this trailer for the midseason premiere, 5.10 “Who Are You” , seems to give the game away surprisingly soon. At the end of the trailer, Laurel (Katie Cassidy) uses her Canary Cry on Oliver and Felicity. “That’s not our Laurel,” says Ollie. And Laurel (or whoever she is) coldly replies, “Finally, it’s about time someone figured it out.” So, is she Earth-2’s evil Black Siren from the comics? It seems likely. But even if not, we’re surprised the trailer didn’t keep the “is she or isn’t she real Lauren?” guessing game going a bit longer.
“Who Are You?” airs in the States on 25 January and is currently expected to air in the UK on Sky One in early February.
