"Arrow" season 2, episode 23 spoilers will revolve around Oliver Queen and Slade Wilson's showdown as the "unthinkable" happens when Oliver's loved one is kidnapped.

According to cartermatt.com, the finale is going to be one of the most intense and craziest yet as all the previous episodes were leading up to the season climax.

"Arrow" tells the story of an entitled billionaire who is presumed dead when his expensive yacht is lost at sea. Five years later, he returns to the city as the masked vigilante trying to clean up the streets of crime.

In the official "Arrow" season 2, episode 23 spoilers released by CW: Slade Wilson (Manu Bennett) will pursue his diabolical goal of killing another person close to Oliver Queen's (Stephen Arnell) heart.

While Oliver Queen as Arrow has managed to control his demons and leave behind the life of the killer he once was, Slade Wilson's kidnapping of a person close to his heart will force the hero's hand. Is he going to revert to being a killer and do the "unthinkable," as the episode title suggests, or will he remain a hero?

More "Arrow" season 2, episode 23 spoilers involve John Diggle (David Ramsey) taking on Amanda Waller (played by Cynthia Addai Robinson) along with some help from his friends. Thea Queen (Willa Holland), meanwhile, will ask Roy Harper (Colton Haynes) "in her time of need."

"Unthinkable" is written by Greg Berlanty, teleplay by Andrew Kreisberg and Marc Guggenheim. It is directed by John Behring, the CW press release said.

"The thing you have to remember here is that sometimes, you have to make sacrifices to get what you want," Matt Carter wrote on cartermatt.com, although he doesn't really look forward to a potential reunion between Thea and Roy because "he hasn't exactly been a good person lately" after he was corrupted by the mirakuru.

"Arrow" season 2, episode 23 will air on CW on Wednesday, May 14 at 7 p.m.
