"Days of Our Lives" spoilers for the beginning of the week reveal that some very big things are happening in Salem. "DOOL" fans will see Nicole Walker freak out about what she may have done while she was high on Halo during the Martin House party. Viewers will also see some very big moments for favorite fan couples, Chad DiMera and Abigail Deveraux and Sonny Kiriakis and Paul Narita.

Nicole murdered Deimos?

According to the latest "Days of our Lives" spoilers, Nicole is in for the shock of her life when she begins to have memories from the night that Deimos Kiriakis was murdered.

When Brady Black tells her that he found Deimos' cursed amulet in Eric Brady's room, Nicole will remember some of the things that happened that night while she and the rest of the party guests were high after being drugged by the devious Deimos. Nicole will come to the shocking revelation that she was likely the person who killed Deimos, but what does this mean for Nicole's future?

Goodbye Arianne Zucker!

As many "DOOL" fans already know, actress Arianne Zucker will be leaving the NBC soap opera in the very near future, and this could be the storyline that sends her out of Salem for good. Nicole could head to jail for the murder of Deimos, or she may decide to skip town again. However, it seems more likely that "Days Of Our Lives" will send her off, with her daughter Holly in tow, to live in a new city (hopefully) happily ever after, until she may return to Salem again in the future.

'Chabby' engagement excites fans

Meanwhile, "Days of our Lives" won't be all dark and sad this week. "DOOL" viewers will watch as two fan favorite couples take huge steps in their relationships. Chad and Abigail have finally found their way back to one another, and this time around they won't be wasting any time. The couple doesn't want to spend another moment apart, and Chad has already proposed to Abby (again) while she's recovery in the hospital after being hit by a car.

Of course, "Chabby" fans are ecstatic about the reunion, and can't wait to see them get married again.

Sonny and Paul are ready to tie the knot, but trouble is coming

However, there will be another wedding to plan. Sonny Kiriakis is now a free man, and he's ready to live his life with boyfriend Paul Narita. Sonny and Paul have a long history together, and they've recently decided to take their relationship to the next level by living together.

Paul was also there for Sonny after he was arrested for Deimos' murder. Now, Sonny is ready to make it official with Paul, and "Days of our Lives" viewers will watch at the two get engaged this week on "DOOL." However, trouble could be brewing for the pair as they plan their wedding.
