The episode is written by Brian Ford Sullivan and Oscar Balderrama. Directed by Dermott Downs and will originally air on October 26, 2016.

There are still a lot more going to happen in this season. The main villain of this season has been revealed and named as Prometheus. Now let's find out why he does want the superhero in the mask to get killed. It seems that Tobias Church established himself as one of the favorite villains in "Arrow", Reporter Times reported. 

"Arrow'' Season 5 has been excellent and has a vast improvement over the last couple of years and Seasons. A big part of that is the fact that Oliver Queen has a new team of recruits, but it still good to watch John Diggle be on the Arrow's side.
