Arrow returns in just a few weeks and the big mystery everyone is looking to see resolved is just how and why Laurel Lance has returned from the dead.

Of course, last month’s trailer for the midseason premiere, ‘Who Are You?’, seemed to have spoiled the answer to this particular mystery. The trailer ends with Laurel using a Canary Cry without the aid of her collar, apparently indicating she may actually be the Earth-2 version of Laurel, the metahuman known as Black Siren.

Promo Problems

Speaking to TVLine, Arrow executive producer Marc Guggenheim had a cagey response to the trailer controversy:

“Without commenting on the promo, which I have nothing to do with…,” said Guggenheim, “[and] without commenting on the spoiler, I would say that the episode ends with laying a very specific seed, with a very specific game plan on our part that we hope to see come to fruition.”

Regardless of who she’s playing, it’s clear Katie Cassidy is here to stay. After Laurel was killed last season, Cassidy joined Wentworth Miller and John Barrowman in signing a new four-show contract that allows her to appear on Arrow, The Flash, DC’s Legends of Tomorrow, and Supergirl.

“Katie is a part of the fabric of the show.”

Katie is the Key

Greg Berlanti, the co-creator and executive producer of all four shows, spoke to Comic Book Resources this week about Cassidy’s importance to the franchise:

Arrowverse Crossover: "Crisis on Earth X"

“We made a deal at the end of that season to bring her back for a bunch of episodes. Katie is a part of the fabric of the show. Because the show, like a comic book, can move in different ways, and characters go and come, everybody that’s ever been a part of the key and core ensemble has always had a place at the table for our show.

“There’s the capacity for her to be [in all four shows]. At this moment, she’s in three of them.”

Black Canary 3.0

With Laurel back in the picture, a lot of fans have speculated about the possibility of seeing a new Black Canary on Arrow. Executive producer Wendy Mericle told TVLine she wouldn’t rule it out:

“There’s definitely a possibility. Look, it’s hard to do a show about Green Arrow without having a Black Canary. I don’t know if it will happen this season or when, but… we are going to be true to origins in the DC universe, and she’s always going to be there.”

Arrow returns on Wednesday, January 25 at 8/7c on The CW.
