On the latest episode of soapy primetime drama "Revenge," Jack made a confession to Emily and a character came back from the dead.

The episode opened with a flashback of Daniel (Joshua Bowman) getting hot and heavy with Sarah (Annabelle Stephenson). It then cuts to the present day, where they are doing the same thing. Although Daniel may be marrying Emily (Emily VanCamp), he is clearly in love with Sarah.

Emily catches them flirting, so she puts on a histrionic scene, telling Sarah she's threatened by her. Sarah is shocked, and says she's not a home-wrecker.

Later, Emily and Aiden (Barry Sloane) share a kiss, but it's interrupted by a mysterious text from Charlotte (Christa B. Allen). She needs Aiden's help because someone took nude photos of her while she was in Europe, then someone stole her phone with all of the pictures on it. Aiden meets up with the guy and tries to make a deal. When it doesn't work, Aiden beats him up, and is able to retrieve Charlotte's phone.

At Emily's bridal shower, Victoria (Madeleine Stowe) blindfolds Emily and tells her she has a surprise for her: her first husband, which Emily purposely told Bizzy (Ana Ortiz) about. Emily reveals to her that it was a marriage of convenience so he could get his green card and be with his partner.

Sarah then tells off Victoria, who said she can no longer go through with the plan to disrupt Daniel and Emily's relationship.

But later, Daniel tells Sarah that he can't commit to Emily, and is really in love with her. They kiss, but Sarah stops before it goes any further, saying he has to speak to Emily first.

Victoria knows all about Daniel and Sarah's secret meeting, and gives the number of their secret "love shack" to Emily. Emily calls and finds out that they're sleeping together. Emily then tells Daniel shocking news: she's pregnant.

Aiden later tells Nolan (Gabriel Mann) that he has a secret to tell that he can't tell Emily.

Margaux (Karine Vanasse) is doing some digging on the Grayson family, and tells Jack (Nick Wechsler) that she can't meet up with him because she's meeting with someone who knows all about Conrad (Henry Czerny). It turns out that person is Lydia Davis (Amber Valletta), who everyone thought had died on a plane at the end of season one.

On the next episode, titled "Surrender," Emily panics when she thinks Grayson manner is about to be sold, and worries about being unable to keep Daniel close until their wedding. 

The synopsis reads: "As the wedding approaches, Emily tries to put the final touches on her plan, but the Graysons seem to slip from her grasp."
