She has been happily reunited with the man she loves and is finally free to resume the life she wants in Salem. However, Nicole may find herself drawn back to her former dark ways as she stumbles across a secret that poses a significant challenge to her happily-ever-after ending with Eric on the Tuesday, Oct. 15 episode of “Days of Our Lives.”

Since Nicole (Arianne Zucker) became free to return to Salem, her life has seemingly fallen into place. Not only is she getting to raise her daughter Holly with no challenges, but she has reunited with Eric (Greg Vaughan) and gotten her job back at the Horton Center on the NBC soap. She also had her divorce from Xander (Paul Telfer) finalized as well, giving her true freedom to live a life free of all the drama that has kept her away for so long. However, the fact that Eric did move on when he thought she was dead will come back to haunt her in a big way.

“Nicole stumbles onto a secret,” spoilers reveal.

Previously, Nicole was the one who answered the door at Eric’s apartment as Rolf (William Utay) arrived on a mission from Xander to stop Sarah (Linsey Godfrey) from leaving Salem for good. The doctor wants to leave town because she is pregnant with Eric’s child and knows she can’t be with him because of his commitment to Nicole, and she feels she has no other option but to leave since she doesn’t want him to know the truth. Xander, however, is in love with her and will do anything to get her to stay, so he gave the results which proved Eric was the baby’s father to Rolf and asked him to deliver the news. He since has had a change of heart and wants to stop him—but even if he can keep the news away from Eric, Nicole may figure it out first.

Now, she will be forced to decide if she needs to tell Eric and risk jeopardizing their future, or if she should go along with keeping the truth hidden.

Meanwhile, Sarah herself will be meeting with Eric to reveal her future plans, and he will be stunned when she admits she wants to leave town.

“Sarah reveals to Eric that she’s leaving Salem,” spoilers state.
