"Days of Our Lives" spoilers reveal that Kristen DiMera (Eileen Davidson) is returning to the NBC soap opera, and rumor has it she'll be out for revenge. As many "DOOL" fans know, Kristen was obsessed with her former step-son, Brady Black, and after he ditched her for Theresa Donovan, things got crazy. While Theresa was pregnant with Brady's child, Kristen drugged her and had the embryo stolen from her body, and implanted into her own womb. Kristen then carried the child and gave birth to him before Brady or Theresa were even aware that they had a child.

Kristen named the little boy Christopher, but her time with the baby was short lived. Brady and Theresa soon figured out what was happening, and set off to find their son.

Kristen's not dead, and she wants Tate

After finding their son, it was believed that Marlena Evans had killed Kristen after pushing her out of a window during a struggle. However, Kristen's body was never found, and it looks like she survived the fall. Kristen will be now returning to "Days Of Our Lives" with one thing in mind, getting Brady and Theresa's baby boy back. Brady's son, whom they re-named Tate, is now living in the Kiriakis mansion with Brady and Theresa is out of the picture after lying to Brady about not wanting to be a mother anymore and heading off on an ISA mission to help take down a drug dealer that she used to run with.

Theresa has not been seen since her exit, but "DOOL" fans desperately want actress Jen Lilley to reprise the favorite fan role.

Will Theresa return to save her son?

If Kristen DiMera returns to Salem with little Tate in her sights, will Theresa return to help keep her son away from the woman who stole him from her in the past?

While it seems that Brady would do anything in his power to keep his son safe, he has been going through some interesting emotional issues as of late. Not only has he been insanely jealous over his current girlfriend Nicole Walker's friendship with his half-brother, Eric Brady, but he's also started drinking again, which is very dangerous for the recovery addict.

As "Days of Our Lives" fans know, Nicole will be gone from Salem soon, and Theresa's return could be just the thing that Brady needs in his life right now.

More big 'DOOL' returns

In addition to Kristen's return, other former characters such as Will Horton (Chandler Massey), Sami Brady (Alison Sweeney), Billie Reed (Lisa Rinna), and Vivienne Alamain (Louise Sorel), are headed back to Salem in the very near future. "Days of our Lives" fans are now hoping that Jen Lilley's name will be added to that list.
