The CW has released some official preview images for the November 23 episode of Arrow, and yes, we do get that “Olicity Thanksgiving” in at least a few photos, but we also have the menace of the Black Siren (Katie Cassidy) and Cayden James (Michael Emerson)!
There are also some nice shots of Team Arrow, and in “possibly huge spoiler” territory, someone is wearing the suit of the Green Arrow… and it’s not John Diggle.
The episode is called “Thanksgiving” and here’s how The CW describes it:
OLIVER AND FELICITY CELEBRATE THANKSGIVING WITH WILLIAM — Oliver (Stephen Amell) celebrates Thanksgiving with his family but the happy moment is interrupted. Meanwhile, Black Siren (Katie Cassidy) returns to wreak havoc on the holiday. Gord Verheul directed the episode written by Wendy Mericle & Speed Weed (#607). Original airdate 11/23/2017.
