While there may be no new episode of Arrow this week, next week’s episode picks up right where ‘Fighting Fire with Fire’ left off. Adrian (Josh Segarra) has Susan (Carly Pope) held hostage and Oliver (Stephen Amell) is on the hunt for answers.

The photo gallery for the episode shows Oliver in some sort of temple (presumably where Talia is) and Felicity (Emily Bett Rickards) joining her new colleague, Alena (Kacey Rohl), in the world of Helix.

Oliver learns the truth about his newest arch nemesis in the trailer for the episode. Two things to note: A) Segarra joins the long line of Arrowverse actors who unexpectedly play evil really well. B) Talia (Lexa Doig) tells Oliver “[Prometheus] calls himself Adrian Chase.” Could Adrian be pulling a Hunter Zolomon (Teddy Sears) and using an alias? (Team Arrow does believe Prometheus is Justin Claybourne’s son.) Could the real Adrian Chase actually be Vigilante–something we sadly won’t find by the end of the season?
