ABC drama "Revenge" season 4 episode 16 titled "Retaliation" will revolve around Margaux LeMarchal (Karine Vanasse), Emily Thorne/Amanda Clarke (Emily VanCamp), Ben Hunter (Brian Hallisay), April (Sarah Lancaster), Victoria Grayson (Madeleine Stowe), Natalie Waters (Gina Torres) and David Clarke (James Tupper).

The trailers and official synopsis of the upcoming episode indicate that the series will return with some thrilling sequence this Sunday, 15 March, at 10pm.

As per the synopsis,  Margaux steps up her plans to take down anyone who stands in her way; an exclusive clip released by Extra TV reveals that she is planning to disclose an explosive secret about Emily to the world in episode 16.

The one-minute, 20-second-long clip begins with a conversation between the business woman and Ben. When Margaux tells the cop that she has located his ex-wife, he refuses to believe her but she shows him a video footage of April.

The sneak peek video gives an impression that  Daniel Grayson's wife is trying to blackmail Emily's new boyfriend for something, as she says: "Let me explain something about your new girlfriend. Where ever she goes, she leaves pain in her way and I know you don't want to fall victim to that or you wouldn't be here. So did you bring what I asked for?" 

The trailer ends by showing something that can help Margaux to drop a bombshell on Emily and its the protagonist's birth certificate, which will prove she is Amanda Clarke and not Emily Thorne.

However, Ben believes that it will not help the business woman to take her retaliation on his girlfriend, since the people close to Emily know her real identity. But Margaux is confident about her new mission and says: "The world out there likes nothing more than to destroy devils who pretend to be angels. When they hear the whole story, she will be crucified."

So it remains to be seen whether  Daniel's wife will succeed in executing her plan, or fail in her mission. Meanwhile, Natalie throws a giant Fourth of July bash and invites David to be her date with a determination to flaunt her new fortune at Victoria's face.
