→ CW’s “Arrow” Casts Its Black Canary

However, given that [Katie] Cassidy’s character is based on the second Black Canary’s alter ego Dinah Laurel Lance, many fans expected that the crusading attorney eventually would turn to vigilantism.

Umm..what? They made a character called Dinah Lance and then are going to have someone else play Black Canary. Why even have Dinah then? I am so confused.
