Episode 15 of The CW supernatural series, "Arrow" season 3 titled "Nanda Parbat" will not just focus on the fight between League of Assassins and the protectors of Starling City but also bring in several surprising twists.

"In this episode, Oliver Queen (Stephen Amell) and John Diggle (David Ramsey) will go to Nanda Parbat to take the fight to Ra's al Ghul (Matthew Nable)," teased Executive Producer Marc Guggenheim.

He also revealed that  "Arrow" fans can expect the most surprising twist of the show in episode 15. However, trailers and sneak peek images of "Arrow" season 3 indicate that Queen and Diggle will fail to save Malcolm Merlyn (John Barrowman) from the custody of League of Assassins as they are seen chained at "Nanda Parbat".

So the protectors of Starling City might require a new superhero to release them from the clutches of Ra's al Ghul and it could be a dream come true for Ray Palmer (Brandon Routh).

Palmer has always been itching to become the city's new saviour and a 30-second-long video clip shows him assembling his Atom suit. 

However, several spoilers have indicated that Felicity Smoak (Emily Bett Rickards) will try to stop him from his move since she believes that it is a suicide mission. In the mean time, the predictions could be wrong so the viewers can tune in to The CW this Wednesday, 25 January, at 8pm for more details on "Arrow" season 3 episode 15 titled "Nanda Parbat". The show will be live streamed.
