Actress Emily Bett Rickards has been cast as Felicity Smoak. Fans may now her as the step-mother to Firestorm in the DC comics.
The character debuted as an antagonist who sued the hero, later unwittingly marrying his alter ego Ronnie Raymond’s father.
The actress will debut in the third Arrow episode alongside Michael Rowe as Deadshot.
Firestorm is not considered a fit for the show, and so is not expected to join his stepmother.
