The second season of Arrow really seems to be expanding the DC television universe, with Black Canary, several villains and of course, The Flash added to the cast lineup. Now TV Line announces that Bex Taylor-Klaus has been added to the cast as Sin.
Sin is a character first introduced during Gail Simone’s Birds of Prey run in 2006. She was adopted by Black Canary, who met her while training for martial arts in Asia. Sin was being groomed to be the next Lady Shiva, and while she was just a young girl, was a deadly martial artist.
The source says that Sin will have connections to Black Canary (played by Caity Lotz) as well as Roy Harper (Colton Haynes). She will appear in the third and fourth episodes of the series.
Taylor-Klaus is best known for her role on AMC’s The Killing, her only major screen credit to date.
Arrow returns to The CW on 9 October 2013.
