Arrow Goes Behind The Scenes On Wednesday's Episode And Asks, "Should We Tell Thea?"

The CW has released a behind-the-scenes featurette in support of Wednesday's episode of Arrow, titled "Canaries."

"We've got some very, very big plot moves -- big ramifications to what Oliver has done over the past three episodes that I think will completely stun and shock the audience," executive producer Robert Guggenheim said, over a series of remarks by characters about whether or not Oliver should finally reveal himself to Thea and bring her into the fold to square off with Ra's al Ghul.
