Victoria Grayson remains clueless on the real identity of Emily Thorne. She visits Leo Mason Treadwell in prison (Roger Bart) to get his assistance. Mason (last seen in Revenge Season 2, Episode 17) has a standing deal with Emily. He spends his time quietly in prison, he gets to write the book of the century.

This week's revengenda involves Pascal LeMarchal (Olivier Martinez), Aiden Mathis (Barry Sloane), and Mason Treadwell. Revenge 3x18 is only a few episodes away from the Revenge Season 3 finale. Fans brace themselves for surprises.

The Revenge page on Facebook carries this Revenge Season 3, Episode 18 synopsis (courtesy of SpoilerTV): "Investigations into Pascal lead Emily and Aiden to uncover some long buried family secrets, while Victoria pays a surprise visit to former ally Mason Treadwell as she gets ever closer to exposing Emily."

"The devil is back," says the ABC promo video for Revenge Season 3, Episode 18. Watch the promo below or go to this YouTube page. Will Mason double-cross Emily Thorne to take advantage of his situation?

Meanwhile, the revengers are already busy hunting spoilers on Revenge Season 3 finale. In an interview for her "Captain America" movie, Emily VanCamp mentions briefly that someone in Ms Thorne's realm dies.

Speaking to NY Daily News, Emily said she was "sobbing over the death of" an unnamed character. Who will die in the Revenge Season 3 finale? It could be Aiden (because Barry Sloan is filming a new ABC series). It could also be Daniel Grayson (Josh Bowman).

That Josh Bowman might exit Revenge is not a new story for those who follow the celebs in this dark ABC series. However, news of Josh leaving came out before it was reported that Sloan is taking on a new project. What happens next in Revenge Season 3?
