Chaos will reign supreme at the DiMera mansion when Sami (Allison Sweeney) finally learns about E.J.'s (James Scott) indiscretions on Days of Our Lives.

Sami Learns The Truth About E.J.'s Affair

In a special episode devoted to the couple on Monday, April 21, Sami will open up an incriminating photograph of E.J. and Abigail (Kate Mansi) together, and the truth about his affair will finally be exposed, just weeks before she planned to wed him once again.

Now, the couple, who survived a stormy history that included E.J. raping Sami back when she was with Lucas (Bryan Dattilo), and Sami shooting E.J. in the head and nearly killing him, could find their relationship at risk once more.

Abigail and E.J. Get Pregnancy Test Results

The question of the hour will be whether or not the couple can now survive E.J. cheating and getting between the sheets with another woman. The only time the episode will break from the couple will be to feature a scene where Marlena (Deidre Hall) and Jennifer (Melissa Reeves) discuss the DiMera family and their tumultuous history.

Sweeney, who announced her plans to leave the soap by the end of the year back in January, spoke to Soap Opera Digest about the episode, and how much she appreciated that the entire episode would be devoted to her character's love story.

"It was such a unique opportunity, and it is an episode that I will treasure having been a part of for the rest of my life," she said. "I was quite flattered that they would want to write an entire episode that was focused on just the two characters."

Days of Our Lives airs Monday-Friday at 1 p.m. on NBC.
