Their wedding was almost over and had gone off without a single issue. However, now that Sami has unexpectedly burst onto the scene and warned Marlena not to marry John, all chaos will break out on the Salem square on the Friday, Aug. 24 episode of “Days of Our Lives.”

John (Drake Hogestyn) and Marlena’s (Deidre Hall) big day seemed to be going well, and they were about to be pronounced husband and wife when Sami (Allison Sweeney), who they weren’t expecting, stumbled up the aisle, tripping in the process and begging her mother not to go through with the ceremony. Now, she will have to explain herself and will warn her mother that she’s in danger, hence why she thinks she shouldn’t go through with the ceremony.

Sami will warn Marlena of a dangerous person who can threaten her happiness, telling her that none other than Kristen DiMera (Stacy Haiduk) is alive, and could threaten everything Marlena holds dear, and the safest thing for her to do is not go through with the wedding and hide.

This will shocking news for Marlena, who previously received a warning from Susan (also Haiduk) that Kristen was alive. The other woman, who isn’t known for being stable, told Marlena that Kristen had come to see her when she was in locked away in a hospital in Nashville, which was only a few months ago. Marlena dismissed Susan’s claim as being a hallucination while she was heavily medicated, but now, she may realize it’s true after Sami also makes claims about Kristen being alive.

However, even if she believes her daughter, it may be too late to do anything to save herself, as Kristen herself will then show up at the wedding too—and will approach Sami with a gun drawn.

This will prove to be the disaster Marlena feared for her wedding since Kristen will want revenge against Marlena since she was the woman who pushed her out of a window in Italy, which was why she was presumed dead. Now, as she arrives at the wedding with a gun in hand, everyone could be in trouble.

“Days of Our Lives” airs weekdays on NBC.
