Arrow Season 3 Spoilers: Will Laurel Find Out About Sara's Killer?

Season 3 of the CW's Arrow returned with a new episode entitled "Left Behind" on Wednesday night, and the end of the episode featured Laurel suiting up as the Black Canary in honor of her sister, Sara. But will Laurel every actually find out who killed Sara?

The fans and the rest of Team Arrow know that Thea fired the arrows under the control of Malcolm Merlyn, but will Laurel ever find out? The "Spoiler Room" column at EW.com has some information.

"Will Team Arrow actually tell Laurel that Thea killed Sara? - Brian
That's the big question once Laurel joins the team. 'Laurel will find out who killed her sister,' Katie Cassidy tells me. 'The audience will be surprised by her reaction. I feel like I wouldn't be surprised if Laurel lost it on Thea, but people will be surprised and excited.' As for the big 'Canaries' episode coming up, Cassidy says, 'There's going to be some crazy badass scenes of the Canaries fighting.' Make of that what you will."

In case you missed it, here's what we had to say about Laurel in last night's episode.

"And finally, Laurel has suited up as the Black Canary. For weeks and weeks, fans have complained that she has no business taking up Sara's mantle. She's not trained enough. She's too weak. It doesn't make sense.

But the writers said all along to have faith, and that faith was justified tonight because the show managed to expertly craft a logical reason for her jumping into the costume. Oliver's team had all but given up. Ra's al Ghul had killed him, and Sara's death was going to stand without justice. So she saw the gloves, the mask, and the wig and decided to take matters into her own hands. Laurel is going to get hurt, probably a lot, but her reasoning makes sense."
