Arrow: Sister Vs. Sister In New Canaries Clip

USA Today has posted a new clip from tonight's "Canaries" episode of The CW Television Network's hit comic book-based series, Arrow.

Finally! Canary-on-Canary action! Watch as Laurel (Katie Cassidy) gets beaten up by her dead sister Sara (guest star Caity Lotz) while they both are wearing their Black Canary costumes. This is of course a powerful hallucination caused by Vertigo (guest star Peter Stormare), who has dosed Laurel with his mind-altering drug.

Watch the "Canaries" clip in the video below.

Destruction is the very nature of Vertigo. Arrow is all new Wednesday at 8/7c!
