Black Canary & Black Siren Have A Scream Fight on Tonight's 'Arrow'

Black Canary and Black Siren are about to have the most epic fight on Arrow tonight.

The episode brings Oliver being pushed over the edge by Cayden James once again and now, knowing that everyone and everything he loves is in danger, he must decide if he can do this alone or if he needs to turn to his old teammates for help.

For Siren vs. Canary, star Juliana Harkavy recently chatted about their rivalry.

“There is a lot of bad blood between Siren and Canary,” she told Variety. “It’s fun to watch those fights – they’re very charged because of the history of where they came from and what they’ve been through.”

“People who like those fights can definitely come to expect more of them, and they’ll get bigger and better.”

Arrow airs TONIGHT @ 9PM ET/PT on The CW.
