As we all know in Season 2 of the Arrow Cassidy Alexa appeared as Harley Quinn in the episode for a very short time in the episode that formed the Suicide Squad. Well the CW said she'd never be returning to Arrow because of the movie that is coming out. Well I think they should bring her back! She's a wonderful Harley Quinn and as a very big fan I think she makes a better Harley Quinn than the one in the movie and she does a fantastic job with her voice! Please sign and share this petition and bring her back!!!
