"Revenge" Season 3 returns to ABC on Mar 9 with Episode 14, titled "Payback." The show's latest promo video shows Emily Thorne (Emily VanCamp) telling Nolan Ross (Gabriel Mann) that she will "kill them all." But first, she has to end her blackouts. New enemies are expected to make the series more dramatic. Meanwhile, fans are worried over Barry Sloane's Aiden Mathis. Will he die, too?

Why is Emily Thorne having blackouts? Viewers connect the blackouts to the gunshot wound and trauma Emily suffered. But there could be another reason for it. Ms Thorne is losing control in Revenge Season 3. "Kill them all" must mean she is getting back up soon.

"Barry Sloane's Revenge days may be numbered," said The Hollywood Reporter. Sloane was cast in a new ABC show called "The Visitors." This Steven Spielberg-produced series could mean the death of Aiden Mathis in Revenge Season 3.

Aiden Mathis killed Satoshi Takeda in Revenge Season 2. Now it seems Takeda's daughter Niko (Stephanie Jacobsen) has connected the dots. Will he die in her hands? Spoilers in the promo video show Emily Thorne in a fight with Niko. This fight may or may not be about Aiden's death, so revenger fans must watch this week's new episode.

Still in Revenge Season 3, Episode 14, The Hamptons' Queen Victoria (Madeleine Stowe) is going to have a confrontation with the first Mrs Grayson, played by Gail O'Grady. She is a cougar, according to spoiler reports, with links to Jack Porter (Nick Wechsler). Would she be Emily Thorne's new enemy, or will they be fighting the Graysons together?

"We're pretty excited about [Stevie] and she brings with her secrets that will also blow you guys away that are going to be great," Revenge Season 3 showrunner Sunil Nayar has previously said. Meanwhile, Nayar, who took over the series in 2013, has yet to receive a renewal notice.

Hopes for Revenge Season 4 is getting dim. In various reports, Josh Bowman had purportedly hinted he would want out (as Daniel Grayson) if the series gets another year on ABC. Daniel is expected to become a darker character this season. His revengenda could already be digging his own grave, worried fans point out.
