Watch the Promo for Arrow “The Demon”

The promo for the next new episode of Arrow has been released. The episode is called, “The Demon” and it will air on November 12.

In the episode, “Felicity (Emily Bett Rickards) learns something new about Oliver (Stephen Amell) that shocks her. Meanwhile, Diggle (David Ramsey) asks Curtis (Echo Kellum) to go undercover for ARGUS. Dinah (Juliana Harkavy) works with an unlikely ally.”

I wonder what the secret is. I wonder if it has something to do with the League of Assassins.
