'Arrow' Season 5 Spoilers: Diggle Out Of Prison? Episode 4 Images Released!

DC character Oliver Queen (Stephen Amell) has been balancing his days between running the city as the Mayor, and running through the streets as the Green Arrow in "Arrow" Season 5. The "Arrow" heroes have been disbanded, with John Diggle (David Ramsey) in the army and Thea Queen (Willa Holland) as Mayor Oliver Queen's Chief of Staff.

The episode finale of "Arrow" season 4 ended with the death of Laurel Lance (Katie Cassidy), aka The Canary. This affected Queen and his band of vigilantes, which led them to part ways. Detective Quentin Lance (Paul Blackthorne), the father of Laurel Lance, became an alcoholic and resigned as the captain of the Starling City Police Department (SCPD).

In the meantime, Queen introduced himself to the new team "Arrow" as the Green Arrow and the Mayor of Starling City. The new team "Arrow" are Ragman (Joe Dinicol), Wild Dog (Rick Gonzales), Evelyn Sharp (Madison McLaughlin) soon to be known as Artemis, and Curtis Holt (Echo Kellum) who will be known as Mr. Terrific in the future episodes.

The characters can be seen in some teaser images for "Arrow" Season 5 Episode 4 that was released on Comic Book.

New villains were seen as well, including a man in an ancient cloak who calls himself as Prometheus, and Tobias Church (Chad Coleman), who wants to rule Starling City and has tried many times to kill Oliver Queen, only to be stopped by Team Arrow.

Meanwhile, Diggle was framed and imprisoned in the previous episode of the "Arrow". Oliver and Lyla Diggle (Audrey Marie Anderson), John's wife, teamed up to rescue John from the military reserve he was taken to.

A preview of episode 4 of "Arrow" showed Oliver and John breaking out of the prison, which would make John a fugitive on the run. A scene with Wild Dog's bloody hockey mask was also seen after an attack from Tobias Church.

Did the new recruits of Team Arrow failed to defend and protect the city? Was Oliver Queen successful in getting John Diggle out of prison?

Find out in season 5 episode 4 of "Arrow" entitled "Penance" which will air on October 26 on The CW.
