Hell hath no fury like a Sami scorned, and, last week on Days of Our Lives, viewers learned that the fiery blonde knows all about her fiance EJ's affair with Abigail. In fact, she has an envelope full of photos of the twosome in compromising positions from their rendezvouses on Smith Island.

So far, Sami hasn't said a word to EJ or Abigail. However, she has gone out of her way to make things as uncomfortable as possible for the twosome; going so far as asking Abigail to be her maid of honor.

But anyone who knows Sami, knows she's got to have a plot against EJ up her sleeve. and apparently it somehow involves Kate. But what it is? What will Sami do about her fiance's affair?

"Just you wait," seethes Sami in this week's Days' preview, intimating that she's got something big and explosive planned.

In an interview with Soap Opera Digest, Alison Sweeney admitted she was on board for this surprise storyline twist the moment she heard about it. She also explained that Sami was filled with rage over EJ and Abigail's betrayal and that that was the emotion she was clinging to -- "the anger, as opposed to the fantasy episode which was the hurt and the betrayal."

With that anger comes Sami's desire for payback and Sweeney doubts her character "has limits" when it come to that part of her personality.

So as Sami and EJ's wedding day approaches, what happens next? "There are a lot of pieces to this plan. Will she go through with the wedding or not?" proposes Sweeney, adding that that's the big question.

Meanwhile, across town, there's another blonde with a plan: Eve Donovan. Jennifer's old high school rival returns to stir things up. And it looks like it's going to be a battle royale between the two nemeses.

This week, Eve surprises Jennifer, when she arrives on her doorstep. And it's not to say, "Hey, I'm back in town. Let's do coffee and catch up." Eve's there on a mission and it involves the late Jack, who longtime viewers will recall is her ex-husband.

"I'm here to collect what is due me," she announces to a stunned Jennifer.

"You're a conniving witch," retorts Jennifer, who later clings to a picture of her beloved Jack as tears fill her eyes.

What will Eve and Jennifer's reignited feud mean for their children Paige and JJ? The two high school graduates have fallen hard for one another and were hoping to spend a romantic summer together before Paige heads off to college.

Considering the state of their mothers' relationship, one thing's for sure. The twosome probably aren't going to get their moms' blessing moving forward.
