"I need you, the team needs you, the city needs you. I'm not saying you shouldn't do your penance. You probably should, but do it as Spartan."
Oliver convincing Diggle to return to Star City
"Penance" is the fourth episode of the fifth season of Arrow, and the ninety-sixth episode overall. It aired on October 26, 2016.


Oliver and Lyla team up on a secret mission for Diggle. Felicity finds out and disapproves of the plan and opts to stay behind. When Tobias Church launches a deadly assault against the city, Felicity must decide if she wants to send the recruits out without the Green Arrow.[src]


  • Escaping a military prison after being framed for a crime the prisoner didn't commit is likely a reference of The A-Team.
  • There are two references to George Lucas' films:
    • The way Rory Regan says, "Sorry about the mess" is a nod to Han Solo from Star Wars.
    • John's cell # is 1138, a number commonly used in pop culture after the George Lucas film THX 1138 and referenced in the Star Wars and Indiana Jones series.
  • Oliver escapes with John just as Batman did with Lau in the film The Dark Knight, using a Fulton surface-to-air recovery system.
  • The title comes from a line where Oliver convinces Diggle to return to Star City.



Production ran from July 27 until August 8, 2016, with a break for British Columbia Day on August 1. Shooting ran from August 9 until August 18, 2016.[1]
