Oliver Queen and Felicity Smoak will have a difference of opinion in Arrow season 5 episode 4, titled Penance. The sequel will air this Wednesday, October 26, at 8 pm EST on The CW.

But the IT expert will not be the only one disagreeing with the saviour of Star City as the new recruits will also try to stop him from his new mission. Although the male lead is all set to succeed in the mission even at the cost of his life, he will have big ramifications in the future.

The official trailer for the next episode has already hinted at bloodshed. So, it remains to be seen if any of the new recruits will meet their demise in the sequel. Click here to watch Arrow season 5 episode 4 live online. Penance will also be available online on The CW website.

The promo begins with a conversation between the on-screen couple, wherein Stephen Amell's character suggests prison break to release his friend, John Diggle. The clip then takes its viewers through a brief argument between the male protagonist and his new recruits, which gradually turns into a fight.

The sneak peek video even features a showdown between Tobias Church and the saviours of Star City after the villain launches a deadly assault against the city. In Oliver's absence, it is up to Felicity to decide whether to trust the new recruits or not.

Meanwhile, a short summary for the fifth episode indicates that one of the new recruits will be captured and tortured by the deadly villain. Since the trailer for episode 4 ends with a shot of Rene Ramirez aka Wild Dog's mask lying on the floor, it can be assumed that he will be the victim.

Here is the official synopsis for Arrow season 4 episode 5, titled Human Target: When the villain captures and tortures a recruit, the male lead must turn to an old friend, Christopher Chance aka the Human Target, for help. Meanwhile, the female lead's worlds collide when Detective Malone joins the ACU.
