Things are just getting bigger and bigger for Mayor Oliver Queen as he will face his biggest challenge yet in "Arrow." The upcoming episode of Season 5 titled "Fighting Fire with Fire" will show how he would deal being the target of the vigilante.

In the previous "Arrow" episode called "The Sin-Eater," Green Arrow became the target of ACU's arrest after being involved in Detective Malone's murder. TV Fanatic called it one of the worst episodes of the series, saying it is all over the place. Maybe they can save themselves by giving a justice to the next episode.

"Arrow" Season 5 episode 15 sees Mayor Oliver Queen becoming the target of a vigilante group. So far, CW released a synopsis saying that the episode titled "Playing Fire with Fire" would give Oliver one of his biggest challenges yet.

In an articled posted by Comic Book Movie, Mayor Oliver Queen will face major problems to deal with. They also said that he would have to come face to face with his biggest challenge yet not only as the Green Arrow but as the mayor of the Star City.

In a preview posted by Carter Matt, a vigilante reported that Mayor Oliver Queen assaulted someone while he is on his duty. With that, Diggle is forced to take the lead and puts everything on the line just in order to defeat the vigilante.

Mayor Oliver Queen is not the only main focus of this episode. The character of Felicity will be explored more as the show will see her dark side. Her work with Helix would show to the viewers how she will eventually lead to her dark side.

Arrow Season 5 Episode 15 will air on March 1 on CW. More details about the episode will leak soon so stay tuned.
