Season two of Arrow goes on sale on DVD and Blu-ray this Tuesday, but a description of one of the deleted scene featured in the set has now started doing the rounds. It features Harley Quinn, the fan-favourite Batman character who was teased in the "Suicide Squad" episode where she was played by Cassidy Alexa and voiced by Tara Stong (the latter has provided the vocals for Harley in everything from animated movies and TV shows to video games). Details are vague, but we apparently get a proper look at Harley this time and she has a lot more dialogue, including calling a shocked Diggle, "Chocalte Puddin'"! During a recent appearance at the Phoenix Comic-Con, Stephen Amell told one fan that, "I don't know if she's going to be involved in Season Three but the high-pitched voice in Episode 16, "Suicide Squad" was absolutely Harley Quinn." It would be a shame to tease fans with a cameo like this for it not to pay off further down the line, and a character like Harley Quinn wouldn't seem all that out of place in the world of Arrow now that The Flash is introducing some more colourful characters. It would certainly make for an interesting episode!
