Arrow - Caity Lotz Returns in Canaries Trailer

"A dose of Vertigo will make the dead rise." This weeks trailer for Arrow shows off a familiar face. Caity Lotz reprises her role as Canary. After Laurel gets hit with a dose of Vertigo, she hallucinates an epic battle with her sister, Sara — both of ‘em fully dressed in their costumes.

Felicity continues to aid Ray with his Atom exosuit, and Oliver — who’s back to taking on crime in Starling City — and Roy appear to be having a serious conversation with Thea. 

Obviously, many things are going to be different for Oliver in this episode, and while things have certainly been crazy so far, things have only just begun. With the return of Green Arrow, and peace being restored to the Glades, it is time to focus on getting the streets back in order. 

CW have released a synopsis for the Canaries episode. Check it out below, and the trailer below that. 

Oliver (Stephen Amell) is thrown by the changes within Team Arrow. He’s used to calling the shots but sees that the team has evolved in his absence and tensions quickly escalate in the lair. Oliver is furious that Laurel (Katie Cassidy) has been going out as the Black Canary and tells her to stop risking her life, but when Vertigo (guest star Peter Stormare) hits the streets again, Laurel goes against Oliver’s wishes and tracks down Vertigo who hits her with a full dose of the drug. Laurel’s biggest fears revolve around her sister Sara (guest star Caity Lotz) so the Vertigo causes her to hallucinate an epic fight between Canary and Black Canary. Meanwhile, Chase (guest star Austin Butler) surprises Thea (Willa Holland), and Roy (Colton Haynes) warns Thea to stay away from Malcolm (John Barrowman).
