Arrow Season 2 Episode 20 title revealed, plus Episode 17 description

The CW's Arrow aired its game-changing Season 2 installment, "The Promise," on Wednesday. But while fans are still digesting everything that went down, two pieces of information about future episodes have come to light.

Firstly, executive producer Marc Guggenheim tweeted the cover for the script of Episode 20, entitled "Seeing Red." The episode started filming Wednesday. This has led some fans to speculate that Roy will turn into Red Arrow in this episode, but of course only time will tell.

The official description for Episode 17, entitled "Birds of Prey," has also been released, and it reveals the return date of Huntress to the show. Moreover, it reveals that a showdown is in the cards for Huntress and Black Canary. Check out the description:

"WHEN THE HUNTRESS MET THE CANARY - When Frank Bertinelli (guest star Jeffrey Nordling) is arrested, Oliver (Stephen Amell) knows it's only a matter of time before his daughter, Helena, AKA The Huntress (guest star Jessica De Gouw), returns to town. To make matters worse, Laurel (Katie Cassidy) is picked to try Frank's case, putting her right in the path of Helena. Oliver tells Sara (Caity Lotz) he will handle his ex-girlfriend, but when Helena takes hostages at the courthouse, including Laurel, the Canary will stop at nothing to save her sister. When The Huntress and Canary meet, an epic battle begins. Meanwhile, Roy (Colton Haynes) realizes he needs to keep Thea (Willa Holland) safe, but doesn't like the way he is forced to go about it. John Behring directed the episode written by Mark Bemesderfer & A.C. Bradley."
