On the March 16 episode of "Days of Our Lives," Chad DiMera (Billy Flynn) and Lani Price (Sal Stowers) will interrogate Stefan (Tyler Christopher) regarding the murder of Andre DiMera (Thaao Penghlis). Meanwhile, Abigail Deveraux's (Marci Miller) not-so-good alter ego, Gabby, will be facing a problem that requires the solution of pretending to be Abigail.

Chad still believes that Stefan was the one who murdered Andre. Following what his gut says, he ransacked Stefan's office to find any evidence linking Stefan to Andre's murder. There, he found Andre's missing cellphone which he immediately turned over to the police. Lani had previously arrested Gabi Hernandez (Camila Banus) for what happened to Andre and learning about Stefan hiding an important piece of evidence will pique her interest. The two will then be interrogating Stefan to find answers surrounding Andre's death. 

Will Stefan reveal the truth about who killed Andre? Will he finally reveal that Abigail or, more importantly, her alter ego Gabby, is the one responsible? Will Abigail's condition be finally be revealed?

Speaking of Gabby, she will be facing a somewhat huge crisis in the upcoming episode. She will, unexpectedly, bump into Kayla Johnson (Mary Beth Evans) and Abigail's mother, Jennifer Horton (Melissa Reeves). Because of this, Gabby will be forced to act and pretend like the normal and sane Abigail. Of course, it is inevitable that Jennifer will notice that something is wrong with the way her daughter acts, after all she is her daughter. Kayla, on the other hand, will notice that something is not right with "Abigail" but will not comment on her observation.

Assuming Stefan reveals Gabby's part in the murder, will the two women realize that they are in the company of Abigail's alter ego? Will Kayla connect the time Abigail asked her for medical advice regarding her headaches to the appearance of her alter ego?

"Days of Our Lives" premieres weekdays afternoon on NBC.
