'Arrow' Season 4 Episode 5 Spoilers: New Episode Leaked Prior to Broadcast; John Constantine Will Arrive in Star City

Just a few days before "Arrow" season 4 episode 5 airs, the episode was leaked online, and showed that John Constantine, played by Welsh actor Matt Ryan, will help Oliver Queen (Stephen Amell) in dealing with Sara Lance (Caity Lotz), who lost her soul after she was brought back to life.

According to The Mirror UK, the leak for the upcoming episode entitled "Haunted" was believed to be a copy that was sent to journalists and reviewers by The CW. Design & Trend also noted that since the leaked "Arrow" episode is a copy meant for screeners, it does not have any extra features, like special effects, added on it. The report also said that even if the copy was not "polished" with any special effects, it did not stop a lot of "Arrow" fans to download the video. Variety said that the leaked episode has now been downloaded more than 11,000 times after it has been released.

Prior to the said incident, a preview was released by The CW for the upcoming episode on YouTube, and it shows John Constantine being asked by Oliver to go to Star City, to help them restore Sara's soul. Damien Darhk (Neil McDonough) was also seen on the clip saying just to take Sara back to the grave.

John Diggle (David Ramsey) asked Constantine what if something goes wrong during the process of restoring Sara's soul. The DC character just calmly replied, "Then, we'll be all too dead to care."

Spoilers Guide has posted a synopsis of the new "Arrow" episode, and the summary reads, "When things take a turn for the worse with Sara (guest star Caity Lotz), Oliver (Stephen Amell) calls in a favor from an old friend who deals in the mystical, John Constantine (guest star Matt Ryan)."

Watch "Arrow" every Wednesday on The CW.
