Days of Our Lives (DOOL) spoilers update for Monday, October 21, reveals that Xander Kiriakis (Paul Telfer) will hope for good news now that Brady Black (Eric Martsolf) is a free man. Kristen DiMera (Stacy Haiduk) had been withholding the paralysis cure from Sarah Kiriakis (Linsey Godfrey), but Xander will expect her to surrender it now that Brady’s been released.

Of course, Kristen isn’t known for playing fair, so she’s about to change the terms of her deal.

Days spoilers say Kristen will suddenly ask for something else in exchange for the serum – and Xander isn’t going to like what it is!

DOOL fans can expect Kristen to demand Titan before she’ll hand over the formula.

If Xander’s willing to give up the family company he inherited, then Kristen will give him the serum that could help Sarah regain the use of her legs.

While Xander rages over Kristen’s dirty move, Brady will have an important conversation with Sarah.

Days spoilers say Sarah will apologize for lying and having Brady arrested for her hit-and-run accident.

However, Brady knows how out of control Xander was when he thought Brady was responsible.

Brady would be deceased right now if Sarah hadn’t intervened, so Brady may have a hunch about that and thank her.

Regardless, Brady will know Sarah wasn’t trying to hurt him in any way and will offer forgiveness.

Fiona Cook (Serena Scott Thomas) is the only one who really needs to feel guilty at this point.

Elsewhere, Marlena Evans (Deidre Hall) will talk to Kayla Johnson (Mary Beth Evans) about Brady and Kristen’s toxic pull toward each other.

That may never go away, especially since Kristen and Brady are Rachel Black’s (Finley Rose Slater) parents.

Brady confessed that he was basically a Kristen addict, but he assured Marlena that he wouldn’t fall off the wagon.

Marlena may struggle to believe that as she confides in Kayla on Monday’s DOOL episode.

Plus, Kayla will probably offer updates on Steve Johnson’s (Stephen Nichols) Paris mission and shock Marlena by spilling that “Abigail DiMera” (AnnaLynne McCord) isn’t the real thing.

Meanwhile, Steve will push “Abby” to admit she’s a fraud and divulge who she really is.

Days spoilers say “Abigail” will check on Mark Greene (Jonah Robinson) following his head wound and ultimately agree that Chad deserves the whole story.

“Abigail” will be revealed as Cat Greene – and it’ll come out that her mother is Konstantin Meleounis’ (John Kapelos) daughter, Catharina Meleounis (last played by Ellie Patrikios).

Catharina isn’t a buried corpse after all, but Cat and Mark feared she’d become one if they didn’t trick Chad DiMera (Billy Flynn) with this marriage and money plot.

Clyde Weston (James Read) has been pulling the strings, so Cat played along and convinced Chad that his deceased wife had returned from the grave.

Days of Our Lives spoilers say Chad will lash out over all the deception, but our predictions hint that he’ll mostly be distraught over losing “Abby” once more.
