Days of Our Lives (DOOL) preview video for the week of November 17-21 hints that Rachel Black (Alice Halsey) will cause Sarah Horton Kiriakis’ (Linsey Godfrey)

allergic reaction and leave Brady Black (Eric Martsolf) reeling over a sudden medical emergency. As DOOL’s weekly promo begins, Lucas Horton (Bryan Dattilo)

wonders if Sami Brady’s (Allison Sweeney) speedy engagement is all about getting under her exes’ skin. EJ DiMera (Dan Feuerriegel) and Rafe Hernandez (Galen Gering)

will have a chance to weigh in on that theory soon enough. Rafe will also deliver huge news to Gabi Hernandez (Cherie Jimenez), who’ll be stunned over his updates on Kristen DiMera (Stacy Haiduk) missing bed check at Statesville.

While Kristen’s prison vanishing act continues to make waves, Jennifer Horton Deveraux (Melissa Reeves) will double down on her custody threats.

Days spoilers say Jennifer will present the paperwork to Chad DiMera (Billy Flynn) and once again vow to take him to court if need be.

Chad will face more pressure to let the kids live in Boston with Jennifer and Jack Deveraux (Matthew Ashford) for the time being.

Another part of Days’ weekly promo shows someone tampering with a drink while wearing black gloves.

Alex Kiriakis (Robert Scott Wilson) will be targeted again since the cup will be next to a takeout bag with his name on it.

Is Jeremy Horton (Michael Roark) up to his old sinister tricks or is some misdirection involved here?

Regardless, Stephanie Johnson (Abigail Klein) could be at risk too if she drinks out of Alex’s tainted cup instead.

Over with Xander Kiriakis (Paul Telfer), his anger issues will flare up. Xander will fume over Brady going after his wife, but Brady will argue that Xander has no say in what Sarah does or who she sees anymore.

It looks like Xander will accept that and meet with Sarah about signed divorce papers, so they may officially close this marriage chapter.

Days’ weekly promo wraps up with Sarah struggling to catch her breath as Brady asks, “Rachel, what did you do?”

Since Sarah is allergic to pistachios and some ice cream sundaes will be on the table, Rachel may give her one with the dessert topping that could prove fatal.

Becoming the source of Sarah’s health crisis could trigger an EJ shooting memory for Rachel, so that’s something to keep in mind.

Days of Our Lives spoilers say Sarah will be OK after some medical attention, but some chaos will erupt in the meantime.
