On the next episode of "Revenge," Emily will struggle to keep her master plan in motion. Then later on in the season, the series' heroine may have to contend with even more potential enemies.  

TVLine revealed that there is a good chance Patrick (Justin Hartley) will be returning for the season's 13th episode, if not sooner. On the 13th episode, Patricks "ruggedly handsome" biological father Jimmy will also be introduced. On that episode, Conrad's (Henry Czerny) first wife, Stevie, will also make her debut, as well as Sara's blue-collar mother, Loretta, who is not happy that she resumed a romance with Daniel (Joshua Bowman). 

TVLine also revealed that "Melrose Place" vet Stephanie Jacobsen is joining the series as a woman from Aiden's (Barry Sloane) past for a multi-episode arc. 

On the lastest episode of the series, Emily (Emily VanCamp) made a confession and a character came back from the dead.

The episode opened with a flashback of Daniel getting hot and heavy with Sarah (Annabelle Stephenson). Although Daniel may be marrying Emily, he is clearly in love with Sarah.

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.

Victoria (Madeleine Stowe) knows all about Daniel and Sarah's secret meetings, 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. 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."

"Surrender" airs Sunday, Dec. 8 at 9 p.m. on ABC.
