Is the Hamptons ready to face Emily Thorne's biggest reveal?

In the teaser trailer for episode 18 of "Revenge" season 4, Emily (Emily VanCamp) makes an announcement in public, and the audience seem shocked with what she says. Does this mean that Emily is about to confess to everyone that she is actually David Clarke's (James Tupper) long-lost daughter Amanda? 

Spoilers claim that Emily is going to have an emotional conversation with her father David, and she tells him that "it's too late" for her to correct the past mistakes that she committed because of her drive for revenge. 

But could the revelation save her from Victoria's (Madeleine Stowe) wrath after Margaux (Karine Vanasse) accused her of pushing her toward a moving cab, causing Margaux to lose her unborn child with David? 

The official synopsis for the episode titled "Clarity" reads: "A grief-stricken Emily tries to repair her collateral damage while Victoria pursues a fresh lead with renewed vigor." 

Will Emily finally shed her make-believe persona and embrace her true nature? But if Emily will indeed declare that she is the real Amanda Clarke, could this mean that her plotted revenge will finally be over? 

Fans are already waiting to find out if the show will return for season 5 now that it only has four episodes left this season. Rumors claim that the final episode for "Revenge" season 4 might also be the series finale.

Currently, different online polls from various entertainment websites like Zap2it claim that the show will likely be cancelled after the current season. ABC is still silent about its plans though, and it is unknown whether the network will renew or cancel the series.

"Revenge" season 4 episode 18 titled "Clarity" airs on Sunday, March 29.
